The U.S. Department of Transportation has estimated that almost half a million vehicle backing accidents occur each year, even though virtually all of these crashes could have been prevented. The following information is intended to help drivers avoid backing accidents, through awareness of the hazards involved, and knowledge of the techniques that can be used to prevent them.

The hazards of backing up

Backing is performed so often that operators may become complacent to the special hazards involved.

The hazards of backing up include:

• Limited visibility of the area behind the vehicle
• The steering wheels are no longer the lead wheels
• Steering response can be quick and exaggerated
• Moving the steering wheel while backing provides an opposite vehicle reaction, as compared to when traveling forward
• Vehicle and trailer combinations can be more difficult to maneuver in reverse

Tips on backing

The best way to avoid backing hazards is to avoid backing up altogether. Maneuver the vehicle so that it does not have to be backed in or out. If that’s not possible, operators should consider the following:

• Scrutinize the area behind and around the vehicle. Make sure that a clear view is provided.
• Safely park then exit the vehicle. Check the intended path of travel for obstructions (posts, fences, power and communication lines, utility poles, pot holes, uneven surfaces, etc.).
• If obstructions are present, check for adequate clearances (width, height, length).
• If the vehicle must be turned while backing, position the vehicle so that the turn is made on the driver’s side, allowing for a better view.
• Use a competent ground guide to assist, but remember that doing so never relieves you of the responsibility of backing up.
• If using a ground guide, have the guide stand away from the vehicle on the driver’s side, in a position with a clear view, that allows for good communication.
• The operator should frequently check both mirrors while backing, but should never rely on mirrors alone.
• Proceed slowly. Back up no farther than absolutely necessary.
• Use your horn and four-way flashers.
• If anyone or anything enters your blind spot, stop and do not move until you see him, her or it reappears.
• Make every attempt to avoid having to back into traffic.

Conclusion

Awareness is key to identifying and recognizing backing as a special hazard, requiring thought and attention to proper technique.

Operators must competently perform this essential driving task every time.

Employing proper backing procedures, and practicing when possible, will sharpen backing skills, and help to prevent backing accidents.

The purpose of this program is to protect employees from injuries due to the potential release of hazardous energy while servicing and maintaining equipment and comply with OSHA 29 CFR 1910.14 — Control of Hazardous Energy.

Scope

This program establishes requirements for hazardous energy control. It is to be used to ensure that machines and equipment as described in Attachment B are isolated from all potentially hazardous energy sources:

1. Whenever servicing or maintenance activities are in progress or when equipment guards or other safety devices are removed.
2. An employee is required to place any part of their body into an area on a machine or piece of equipment where work is actually performed upon the material being processed (point of operation) or where an associated danger zone exists during a machine operating cycle.

Responsibilities

Program coordinator

The program coordinator is designated by the employer and is responsible to oversee the implementation of this program.

Specific responsibilities include:

1. Providing Hazardous Energy Control training to employees and supervisors.
2. Maintaining a current listing of employees who have completed lockout training (Attachment A in PDF)
3. Maintaining a current listing of all equipment/machines which fall under the Hazardous Energy Control program (Attachment B in PDF). Listing is to be updated each time a change occurs.
4. Implementing and enforcing this program
5. Maintaining an adequate supply of padlocks and DANGER tags for use each time a lockout process is performed, conducting an annual inspection and review as required by section VII of this program.

Supervisors

Supervisors are responsible for the effective implementation of this program and to see that all required procedures are followed in every instance and will initiate all lockouts.

Employees

Employees are responsible for learning and following the procedures and practices developed under this program and follow the instructions of their supervisor. Employees will be designated as authorized, affected or other and will receive training based on their designation.

Basic lockout procedures

All equipment must be locked out and tagged to protect against accidental or inadvertent operation. Locks are to be applied and removed only by the authorized employee who is performing the servicing or maintenance. No one should attempt to operate locked out equipment.

Lockout devices (padlocks, hasps, etc.) with an appropriate DANGER warning tag shall be used only for energy control. Prior to the servicing or maintenance of equipment a padlock and DANGER warning tag will be obtained from the designated lockout center. Each padlock must be keyed differently with no master key or duplicate keys available.

All electrically energized equipment should be verified as zero energy state through the use of testing equipment by a qualified person.

Training

Each authorized employee must receive training in the recognition of applicable hazardous energy sources, the type and magnitude of the energy available in this workplace, and the methods and means necessary for proper energy isolation and control of the energy source.

Each affected employee working in the area of the equipment lockout must be instructed in the purpose and use of the energy control procedure and their roles and responsibilities during lockout operations.

All other employees who do not work in areas where lockout may be used must be provided a brief overview of the lockout program so they can identify when a lockout is used.

Training in lockout should be given to all new employees as a part of their orientation. Retraining should be conducted whenever there is a change in job assignment, a change in machinery or equipment or process change that presents a new hazard or energy source.

Names of authorized employees who have received appropriate lockout training are identified on the Hazardous Energy Control Training Record (Attachment A in PDF).

Lockout instructions

Authorization

Identify the persons who are authorized to lockout the machine or equipment using this Lockout/tagout procedure

The following procedures are adapted from OSHA 1910.147 — Control of Hazardous Energy

• Step 1: The authorized employee will identify the energy source(s) that the machine or equipment uses, understand the hazards of the energy source(s), and the method(s) to control the energy before using this procedure.
• Step 2: All affected employees must be notified that the machine or equipment is to be shut down and locked out for service or maintenance. Notification will be made to all employees who may enter or be working in the area where the equipment lockout is to be initiated.
• Step 3: The machinery or equipment must be shut down using the normal stopping procedure as identified by the instructions used for the equipment.
• Step 4: The machinery or equipment must be completely isolated from its energy source(s).
• Step 5: Each employee who will be performing work on the machine or equipment must use an individual lock on the energy isolating device.
• Step 6: If any residual or stored energy is present it must be released or controlled.
• Step 7: Verify all energy sources are isolated pressing attempting to start the machine that is locked out. Ensure all start controls are returned to their off or neutral position.
• Step 8: For electrically energized equipment, a qualified person must use electrical testing equipment on the load side of the equipment being locked out to verify there is no electrical energy present.

Release from lockout/tagout

Return the machinery or equipment to its normal operating condition

• Step 1: Check the machine or equipment and the immediate area around it to make sure all nonessential items (tools/materials) have been removed and that the machine or equipment is ready to energize. Ensure all guards have been replaced including interlocks, if so equipped.
• Step 2: Make sure all employees are safely positioned away from the machine or equipment
• Step 3: Verify that the controls are in neutral or off position.
• Step 4: Remove the lockout devices and reenergize the machine or equipment.
• Step 5: Notify affected employees that the servicing or maintenance is completed and the machine or equipment is ready for use.

Periodic review

At least annually, the program coordinator or auditor must verify the effectiveness of the energy control procedures. The review must include a demonstration of the procedures and may be carried out through random audits and observations.

The program coordinator or auditor must review the Hazardous Energy Control Procedure with all authorized employees, and actually observe the employees using the Hazardous Energy Control Procedure. The review must be certified and documented by the auditor. A sample Hazardous Energy Control Lockout Program Inspection form is attached. (Attachment C in PDF).

The review is to ensure that the energy control procedures are being properly used and authorized employees can ask questions related to the procedures. Any deficiencies must be corrected immediately, either by modification of the procedure, retraining of employees, or a combination of both.

Outside contractors

Outside personnel or contractors involved in lockout of equipment or machinery that affect facility employees must inform facility management of their energy control procedures and be informed of the energy control procedures used by the facility.

Here is what you can do to help protect your equipment

When a transformer overheats, circuit breakers trip, or electronically controlled variable speed motor controllers drop off-line, all for no apparent reason, should you look only at the utility as the source of the problem, or should you also look at your own plant and equipment as the possible culprit? The answer may be both.

The microwave clock was blinking again, its bright LED display flashing. The power had gone off for a brief moment. Yet, plugged into the same outlet as the microwave was an old electric motor driven clock, the sweeping hands of its analog dial seeming to not miss a beat. Has this ever happened to you? How many times have you had to reset digital clocks, the VCR or DVD recorder, or the microwave oven in the last year? When a momentary power interruption occurs at home, it can be a source of irritation. When the same momentary interruption occurs in an office, a process line, or production line, the result can be a costly equipment breakdown.

What’s the problem?

A momentary power outage can occur within thousandths of a second, and may only be obvious by a very rapid blinking of lights. Years ago a momentary outage was not considered a problem because, under most conditions, it was not perceptible. At that time, the majority of electrical equipment was based upon electro-mechanical technology, a technology which rarely reacted negatively to momentary power outages. A sustained power outage is typically much more readily identifiable, since it results in a complete loss of power for a comparatively extended time period. Sustained outages have always been considered a problem, but if they occurred infrequently and could not be avoided, most people were willing to accept the inconvenience.

Compared to the older electro-mechanical technology, solid state devices provide reductions in size and weight, increases in versatility and possible reductions in both initial and maintenance costs.

However, solid state devices are very sensitive to power system fluctuations. It is this drawback that brought about the increased awareness of power system variations, a reality of life which had always been present.

Power quality — what is it?

Power quality is a term used to describe an old problem. To most people, power quality means how often the lights go out due to power interruptions. These interruptions can be caused by natural disasters (hurricanes, tornadoes, and ice storms), pole-line accidents, tree contact with power lines and other easily recognized factors. An interruption can be momentary or sustained. Historically, most calls and complaints received by electric utilities have been of the simple “lights out” variety.

Most of the older electro-mechanical equipment was robust and could handle minor changes in voltage with little or no impact on operations. Due to major technological advances several years ago in consumer electronics and commercial and industrial applications of solid state electronics, our understanding and definition of power quality has been expanded. Power system conditions included in today’s definition include harmonic distortion, voltage variations (sags and swells), voltage reductions, power interruptions (momentary and sustained) and voltage surges.

Harmonic distortion

Much of the equipment we use today, such as computers, automated process control equipment and solid state power conversion equipment, contains circuits which convert alternating current (AC) to direct current (DC). When energized, these power conversion circuits, themselves very sensitive to power fluctuations and abnormalities, create harmonics which can severely distort the power supply and cause problems for others connected to the same source.

Most circuits in the United States are designed to operate at a frequency of 60 hertz. The frequency of a harmonic current or voltage is a multiple of the original frequency. For example, in a 60 hertz system, the second harmonic would be 120 hertz; the third harmonic would be 180 hertz and so on. Harmonics add to the fundamental frequency in magnitude and can produce peak voltages greater than the line voltage. These voltages can become a problem when they exceed the design voltage of electrical devices.

It once was extremely difficult and very time consuming to identify the presence of harmonics in a power system. Most electrical measuring instruments could not respond fast enough to detect harmonics. Today, high speed analyzers are available to identify and record the frequencies present in the power system. Software and personal computers also help simplify the process of identifying each discrete frequency. With these tools, troublesome frequencies can be identified in a relatively short period of time.

Once identified, a variety of things can be done to reduce or eliminate the effects of these unwanted frequencies. For circuits generating harmonics, filtering circuits can be designed and installed. For electrical circuits which must carry additional harmonic current, neutral wires with higher current carrying capacities can be installed to minimize overheating and potential fire hazards. For transformers subjected to harmonic loads, the transformer’s load can be reduced to accommodate the additional harmonic current, a larger transformer can be installed, or a transformer designed to handle harmonic currents can be specified.

Whenever changes are planned in an electrical power system or any potentially harmonic producing equipment is to be added, it is important to investigate the susceptibility of the power system to possible harmonic distortion problems. These investigations should be made in addition to any normal power system studies done whenever changes to an electrical system are anticipated.

Voltage sags and swells

When an electric clothes dryer is started, the lights may dim for an instant and then return to normal. In an industrial plant, starting a large motor produces similar results. In both cases the line voltage momentarily decreases due to the inrush of current drawn by the heavy starting load. When a large load is removed from a circuit, the voltage may increase slightly and lights may get brighter for an instant. These events are referred to as sags and swells respectively.

Older electro-mechanical equipment could typically handle these types of changes in voltage with little or no effect on operation. The worst case might be a machine tripping off-line. Modern solid state controls are more sensitive to these voltage variations, and can be damaged by higher voltage levels or trip off-line with a minor drop in voltage. This can become serious in process applications where it either takes considerable time to restart the interrupted process, or the work in progress is lost or a product spoiled.

When these situations occur, equipment owner/operators have successfully worked with electric utilities, consulting engineers and equipment manufacturers to find a solution. The results of this team approach have typically been the development of cost effective solutions to allow solid state controlled equipment to operate normally whenever voltage sags and swells occur.

Voltage reductions

At times of extremely high power consumption, an electric utility may have to reduce the supply voltage for energy conservation purposes. This condition is called a “brownout.” In other cases, the inadvertent overloading of a transformer may cause unplanned voltage reductions. In either case, solid state equipment may not operate within its voltage rating, resulting in malfunction or failure.

In these cases it may be necessary to work with the utility to increase the size of the transformer supplying a plant, develop load management systems for a facility to prevent energizing major loads at the same time, or install an uninterruptible power supply (UPS) system to help protect sensitive loads.

Momentary interruptions

Storms can cause a tree limb to come in contact with a power line. A squirrel or large bird may come in contact with an insulator on a power line or in an electric substation. These events can cause a circuit breaker to trip in order to protect the utility equipment. After the fault is cleared the breaker that opened is able to re-close, sometimes automatically, thereby restoring power. Fault clearing and automatic re-closing typically occur in a matter of milliseconds. Electro-mechanical equipment was generally not affected by these brief outages.

However, computers and other electronically controlled equipment are extremely sensitive to even the briefest power interruption. A momentary power interruption can result in inaccurate data or incorrect signals to a process computer. The result can be an upset in a manufacturing process, a product which cannot be sold due to incorrect mixing or processing, or damage to expensive machinery. The use of a UPS system or other source of emergency power could help the process control system ride through these brief outages with no ill effects.

Sustained interruptions

Sustained interruptions can be caused by storms, accidents involving utility owned equipment, or malfunctions of utility owned equipment. These longer-term power outages can last from hours to days. Extreme examples of sustained outages include the 1965 blackout that affected a large portion of the Northeast and the major outage of 2003 that knocked out power all over the Northeastern United States and Southeastern Canada.

Critical electrical equipment that requires an orderly shutdown should be provided with emergency back-up systems such as emergency generators, batteries, or UPS systems. For example, a furnace in a steel mill requires cooling water to prevent hot metal break-out. The loss of cooling water during a power outage can spell disaster. A back-up diesel driven pump or emergency generator will allow the cooling system to continue to operate, thereby averting a serious problem.

Voltage surges

Surges in an electrical power system can be caused by lightning, utility switching operations and system faults. Surge protection is generally provided by surge arresters located either in the utility system or within the customer’s power distribution system. Power supply circuits for computers and electronically controlled equipment should be evaluated to ensure that the installed surge protectors are properly sized and applied to help protect equipment during a power disturbance.

System reliability

The fundamental quality of utility power systems throughout the world has not significantly degraded. What has changed is that today’s society is a heavy user of solid state electronics. This “power qualitysensitive” technology has accentuated imperfections in the power supply which have always existed.

The equipment of “yesteryear” may have been less sophisticated and larger than today’s solid state equivalents, but it operated very successfully in its electrical environment. It is inevitable that as older equipment is phased out, manufacturers will develop future generations of solid state equipment that are more resilient to an imperfect power supply.

Managing power quality

Problems with power quality are not, and should not remain, mysteries. Although these problems are not always easy to identify and sometimes expensive to investigate, once they are identified and resolved a very high degree of reliability can be restored to a power system.

It is important to remember that an electric utility is at least as interested in the satisfaction of its customers as are the customers themselves. To this end, they are generally willing and helpful in identifying a problem and recommending solutions. Consulting engineers and equipment manufacturers can also serve as resources, providing investigative services and expert advice on power quality problems.

Pool and spa owners and operators play an important role in alerting your customers to the safety behaviors that could reduce pool and spa accidents. Learn more about these behaviors.

Recreational time at public swimming pools and spas is a favorite activity for children and adults around the country. Whether enjoying pool time with family or friends, exercising, playing water sports or learning to swim, everyone needs to be mindful of the potential for drowning, submersion injuries and entrapments.

Since many families spend time at public pools and spas, these visits service as a prime opportunity for owners and operators to join with the Consumer Product Safety Council (CPSC) in reminding families how to stay safe in and around the water.

By encouraging families to take extra safety steps like those outlined below, you can help reduce the number of drowning incidents and submersion injuries that occur every year in the United States.

Staying close, being alert and watching children in and around the pool

Never leave a child unattended in a pool or spa and always watch your child when they are in or near water.

• Teach children basic water safety tips.
• Keep children away from pool drains, pipes and other openings to avoid entrapments.
• Have a portable telephone close by at all times when you or your family are using a pool or spa.
• If a child is missing, look for him or her in the pool or spa first.
• Share safety instructions with family, friends and neighbors.

Learning and practicing water safety skills

• Learn how to swim and teach your child how to swim.
• Learn to perform CPR on children and adults, and update those skills regularly.
• Understand the basics of life-saving so that you can assist in a pool emergency.

Having the appropriate equipment for your pool or spa

Install a four-foot or taller fence around the perimeter of the pool and spa and use self-closing and self-latching gates; ask your neighbors and community groups to do the same at all residential and public pools.

• If your house serves as a fourth side of a fence around a pool, install door and window alarms and always use them.
• Install pool and gate alarms to alert you when children go near the water.
• Ensure any pool and spa you use has compliant drain covers, and ask if you do not know.
• Maintain pool and spa covers in good working order.
• Consider using a surface wave or underwater alarm.
• Have life-saving equipment such as life rings and reaching poles available for use.

Do you allow personal use of your company owned/leased vehicles to employees for their use during or after hours?  This is a common benefit companies will offer to attract and maintain valuable staff; however, it’s important to understand and control the added exposures this creates for your business.  The types of use permitted, restraint requirements, authorized drivers, and the radius of permitted personal use are just some of the considerations a company should outline in their related policies. 

If family members of your employee, such as their spouse, are permitted to drive the company owned vehicle, policies should ensure these permitted family members are approved and vetted using the same driver screening procedures utilized for all staff upon hire and at a minimum annually thereafter.  Family members authorized to drive company-owned vehicles should be required to read and sign your organization’s safe driver policies, including a commitment to remain distraction-free while driving and report all motor vehicle moving violations to your management team. 

Personal miles driven and related tax implications should be discussed with your legal counsel and tax advisor.  Polices should also include collision reporting requirements immediately following the collision or as soon as reasonably possible.  All vehicles should be equipped with appropriate accident reporting and insurance documentation kits. 

Policies should address where the vehicle will be parked (off-street parking requirements) when not in use at the employee’s residence to mitigate theft and struck-while-parked collisions.  Fueling controls, passenger considerations, and appropriate usage including the possible towing of trailers or securing transported items on the roof are also important items to consider within your policies.

LC 2022-321

This report contains a review of the requirements contained in the Food and Drug Administration (FDA) Standard for Microwave and Radio Frequency Emitting Products. Details include information on power density levels, user and service instructions and labeling.

Introduction

The provisions of this standard are applicable to microwave ovens manufactured after October 6, 1971. In 2016, changes were published for Standard for Microwave and Radio Frequency Emitting Products. This report will synopsize the latest version. For complete details, see 21 CFR 1030. Standards on microwave and radio frequency products are administered by the Food and Drug Administration.

Definitions

• Microwave oven means a device designed to heat, cook or dry food through the application of electromagnetic energy at frequencies assigned by the Federal Communications Commission in the normal ISM heating bands ranging from 890 megahertz to 6,000 megahertz. As defined in this standard, "microwave ovens" are limited to those manufactured for use in homes, restaurants, food vending or service establishments, on interstate carriers, and in similar facilities.
• Cavity means that portion of the microwave oven in which food may be heated, cooked or dried.
• Door means the movable barrier which prevents access to the cavity during operation and whose function is to prevent emission of microwave energy from the passage or opening which provides access to the cavity.
• Safety interlock means a device or system of devices which is intended to prevent generation of microwave energy when access to the cavity is possible.
• Service adjustments or service procedures means those servicing methods prescribed by the manufacturer for a specific product model.
• Stirrer means that feature of a microwave oven which is intended to provide uniform heating of the load by constantly changing the standing wave pattern within the cavity or moving the load.
• External surface means the outside surface of the cabinet or enclosure provided by the manufacturer as part of the microwave oven, including doors, door handles, latches and control knobs.
• Equivalent plane-wave power density means the square of the root-mean-square (rms) electric field strength divided by the impedance of free space (377 ohms).

Requirements

The subject standard (21 CFR 1030) specifies several design features for microwave ovens. All parameters must be thoroughly tested by the manufacturer for conformance to the standard.

• Power density limit — The power density of the microwave radiation emitted by a microwave oven must not exceed one (1) milliwatt per square centimeter at any point five centimeters or more from the external surface of the oven.
• Safety interlocks — Microwave ovens must have a minimum of two operative safety interlocks. At least one operative safety interlock on a fully assembled microwave oven must not be operable by any part of the human body, or any object with a straight insertable length of 10 centimeters. Such interlock must also be concealed, unless its actuation is prevented when access to the interlock is possible. Any visible actuator or device to prevent actuation of this safety interlock must not be removable without disassembly of the oven or its door. A magnetically operated interlock is considered to be concealed, or its actuation is considered to be prevented, only if a test magnet held in place on the oven by gravity or its own attraction cannot operate the safety interlock.
  
  Failure of any single mechanical or electrical component of the microwave oven must not cause all safety interlocks to be inoperative.
  
  Service adjustments or service procedures on the microwave oven must not cause the safety interlocks to become inoperative or the microwave radiation emission to exceed the specified power density limits as a result of service adjustments or procedures.
  
  Microwave radiation emission in excess of the limits specified in paragraph (c)(1) of this section shall not be caused by insertion of an insulated wire through any opening in the external surfaces of a fully assembled oven into the cavity, waveguide, or other microwave-energy-containing spaces while the door is closed, provided the wire, when inserted, could consist of two straight segments forming an obtuse angle of not less than 170 degrees.
  
  One (the primary) required safety interlock shall prevent microwave radiation emission in excess of the requirement of paragraph (c)(1) of this section; the other (secondary) required safety interlock shall prevent microwave radiation emission in excess of five milliwatts per square centimeter at any point five centimeters or more from the external surface of the oven. The two required safety interlocks shall be designated as primary or secondary in the service instructions for the oven.
  
  A means of monitoring one or both of the required safety interlocks shall be provided which shall cause the oven to become inoperable and remain so until repaired if the required safety interlock(s) should fail to perform required functions as specified in this section. Interlock failures shall not disrupt the monitoring function.

Measurement and test conditions

Compliance with the power density limit in paragraph (c)(1) of this section shall be determined by measurement of the equivalent plane-wave power density made with an instrument which reaches 90 percent of its steady-state reading within three seconds, when the system is subjected to a step-function input signal. Tests for compliance shall account for all measurement errors and uncertainties to ensure that the equivalent plane-wave power density does not exceed the limit prescribed by paragraph (c)(1) of this section.

Microwave ovens shall be in compliance with the power density limits if the maximum reading obtained at the location of greatest microwave radiation emission, taking into account all measurement errors and uncertainties, does not exceed the limit specified in paragraph (c)(1) of this section, when the emission is measured through at least one stirrer cycle. As provided in 1010.13 of this chapter, a manufacturer may request alternative test procedures if, as a result of the stirrer characteristics of a microwave oven, such oven is not susceptible to testing by the procedures described in this paragraph.

Measurements shall be made with the microwave oven operating at its maximum output and containing a load of 275 +/-15 milliliters of tap water initially at 20 +/-5 deg. centigrade placed within the cavity at the center of the load-carrying surface provided by the manufacturer. The water container shall be a low form 600-milliliter beaker having an inside diameter of approximately 8.5 centimeters and made of an electrically nonconductive material, such as glass or plastic.

Measurements shall be made with the door fully closed as well as with the door fixed in any other position which allows the oven to operate.

User instructions

Manufacturers of microwave ovens are required to provide, with each oven, radiation safety instructions which:

• Occupy a separate section and are an integral part of the regularly supplied users' manual and cookbook, if supplied separately, and are located so as to elicit the attention of the reader.
• Are as legible and durable as other instructions with the title emphasized to elicit the attention of the reader by such means as bold-faced type, contrasting color, a heavy-lined border, or by similar means.

Microwave user instructions must include the following precautions to avoid possible exposure to excessive microwave energy:

• Do not attempt to operate this oven with the door open since open-door operation can result in harmful exposure to microwave energy. It is important not to defeat or tamper with the safety interlocks.
• Do not place any object between the oven front face and the door or allow soil or cleaner residue to accumulate on sealing surfaces.
• Do not operate the oven if it is damaged. It is particularly important that the oven door close properly and that there is no damage to the: (1) door (bent), (2) hinges and latches (broken or loosened), and (3) door seals and sealing surfaces.
• The oven should not be adjusted or repaired by anyone except properly qualified service personnel.
• Include additional radiation safety precautions or instructions which may be necessary for particular oven designs or models, as determined by the Director, Bureau of Radiological Health, or the manufacturer.

Service instructions

Manufacturers of microwave ovens must provide servicing dealers and distributors with adequate servicing and radiation safety instructions which:

• Occupy a separate section and are an integral part of the regularly supplied service manual and are located so as to elicit the attention of the reader.
• Are as legible and durable as other instructions with the title emphasized so as to elicit the attention of the reader by such means as bold-faced type, contrasting color, a heavy-lined border, or by similar means.

Microwave service instructions must include the following precautions to be observed before and during servicing to avoid possible exposure to excessive microwave energy:

• Do not operate or allow the oven to be operated with the door open.
• Make the following safety checks on all ovens to be serviced before activating the magnetron or other microwave source, and make repairs as necessary: (1) interlock operation, (2) proper door closing, (3) seal and sealing surfaces (arcing, wear, and other damage), (4) damage to or loosening of hinges and latches, and (5) evidence of dropping or abuse.
• Before turning on microwave power for any service test or inspection within the microwave generating compartments, check the magnetron, wave guide or transmission line, and cavity for proper alignment, integrity, and connections.
• Any defective or misadjusted components in the interlock, monitor, door seal, and microwave generation and transmission systems shall be repaired, replaced, or adjusted by procedures described in this manual before the oven is released to the owner.
• A microwave leakage check to verify compliance with the federal performance standard should be performed on each oven prior to release to the owner.
• Include additional radiation safety precautions or instructions which may be necessary for particular oven designs or models, as determined by the Director, Bureau of Radiological Health, or the manufacturer.

Labels

Microwave ovens are required to have the following warning labels:

A label, permanently attached to or inscribed on the oven, which must be legible and readily viewable during normal oven use, and which must have the title emphasized and be so located as to elicit the attention of the user. The label must bear the following warning statement:

Property crime occurs every three seconds…theft occurs every five seconds…auto theft occurs every 25 seconds…violent crime occurs every 35 seconds…robbery occurs every 60 seconds. Keep yourself safe.

Remember the acronym: B-SAFE

Brightness

• If you are parking during daylight hours, think about when you will be returning to your car. If it will be dark when you return, park in a well-lit area as close to lights as possible. Even if you plan on returning during daylight hours, park somewhere where your vehicle will be well lit in case you are delayed.
• If parking at night, choose an area that is well lit. If you cannot see your vehicle from a fair distance from the building, park somewhere else. The greater the isolation of the vehicle and the less amount of light, the more the opportunity is created for a thief.

Security devices

• Make sure you lock your car to engage the alarm. If your car is not equipped with an alarm system, consider having one installed. Alarm stickers and decals are a great visible deterrent.
• Other visible deterrents include steering wheel locks and brake pedal locks. These show criminals that your vehicle will take much more time to steal or vandalize, and they will most likely leave and look for an easier target. If you prefer, a whistle can be carried to notify any bystanders if you become involved in a dangerous situation.

Awareness

• Be aware of your surroundings both when parking and returning to your vehicle. Drive through the lot and check it out first if you are unfamiliar with that particular lot. Look around when getting out of your vehicle after parking. If you see any individuals loitering or acting suspicious, park somewhere else and notify the appropriate management or security; this also applies for when returning to your vehicle.
• Keep your keys in hand when returning so you can enter your vehicle quickly if needed. Also, it is always a good idea to check your backseat before entering your vehicle to ensure there is no one hiding inside.

Foliage

• Do not park close to bushes, trees, walls, large vehicles or any other obstruction that may provide a cover for criminals. It can also reduce your ability to see and assess your surroundings. Making yourself and your vehicle highly visible will greatly reduce the chance for creating an opportunity for theft or vandalism.

Enclose

• One of the most important (and easily forgettable) tips, LOCK all doors and make sure all windows are shut TIGHT. Don’t forget to lock the trunk if it locks separately from the vehicle doors.
• When returning to your vehicle, lock your doors immediately upon entering.
• Lock and secure everything even if entering a building for a couple of minutes; it only takes a thief a few seconds to enter the vehicle and steal property or the vehicle itself.
• Hide or remove anything valuable from the vehicle. Conceal them when walking into the building; do not carry valuables in the open. If you cannot take it with you, place it in the glove compartment or trunk and lock it. If that is not possible, cover the items with a blanket as to not make them visible. Even if the items don’t seem valuable to you, they may be valuable to a thief.

One last tip

Back your vehicle into parking spaces if possible. This allows you to be able to leave quickly if a situation becomes dangerous. Note where you have parked; this reduces unnecessary time walking around the parking lot.

If your workers use any type of ladder for their work, the OSHA rules must be followed.

What does this cover?

OSHA rules cover all step ladders, straight ladders and extension ladders whether they are wood, fiberglass or metal. There are rules for installing and using them properly, as well as inspecting them. There are also rules for training workers before they use ladders.

What else do I need to know?

Ladders are the most widely used piece of equipment on construction sites and need to be set up, inspected and used properly every time they are moved to a new work area.

Securing the ladder

Straight and extension ladders have to be secured so they don’t slip or kick out and cause someone to fall. Tying off at the top keeps the ladder from slipping sideways, but remember to secure the bottom, especially if the ladder will be in place for more than a day.

Inspecting ladders

Consider that ladders are not always cared for and can get pretty beat up from constant use. All ladders need to be inspected before they are used. Cracks, loose rivets and bolts, and damaged rungs may eventually cause the ladder to fail. Don’t allow any workers to fix a ladder; only the manufacturer can do that.

Ladder set-up

Most construction workers have heard of the “4:1 rule” which means the bottom of the ladder should be placed 1 foot away from a wall for every 4 feet in wall height. This is how the ladder is tested and gets its capacity rating (Type I, Type IA or Type lAA). Ladders with a designated capacity are the only types of ladders that should be used. Look on the side rail for the ladder Type and rating which will be 250lb, 300lb or 375lb.

Step ladder use

Only allow step ladders to be set-up with the side locking arms locked in place, never allow a step ladder to be leaned against a surface.

Traffic areas

Consider using cones or caution tape around ladders where other equipment is operating or when the ladder might be out of view like around corners or doorways.

What about training?

OSHA rules are in place that require all workers who use a ladder to be trained on proper use, inspection and placement.

Workers should know not to overreach and should follow the “belt buckle rule” which means keeping their belt buckle between the side rails. Make sure you document the training.

Where can I get more help?

The Hanover Risk Solutions website has additional information that you can review or use for worker training. Additional resources can also be found on the OSHA website.

Studies show a link between accidents and past driving performance. Most drivers involved in vehicle accidents have had more than one accident or violation during the prior three years. Past driving record is a good indicator of how the person will drive in the future since drivers often continue their established habits. A recent study found that prior traffic violations were the second best predictor of future accidents, second only to prior accident history. Furthermore, studies have shown that almost half of job applicants understate the number of accidents and convictions in their initial application.

Motor vehicle records

A driver’s Motor Vehicle Record (MVR) is one of the best predictors of accident experience. MVRs should, therefore, be obtained for all drivers before they go behind the wheel. Obtain MVRs from each state since non‐CDL drivers may possess licenses from more than one. Then check MVRs at least once a year to determine if remedial action is needed.

Obtain written authorization from employees when requesting their MVR information. Consult with legal counsel in the event you decide to take disciplinary action against an employee as a result of any findings contained in the MVR, because there may be certain federal or state laws that apply.

Make MVRs part of driver files. Review them with your drivers. Doing so can provide insight into attitudes toward traffic rules and regulations.

Guidelines for screening MVRs

If driving is part of the job, MVRs that are clean or acceptable should be a condition of employment. Establish clear standards for what constitutes an acceptable MVR, and the penalties for not having one.

Consider the guidelines listed on page 3. These are the same guidelines used by The Hanover/Citizens Insurance Companies; however, exercise caution to assure all applicants and employees are evaluated under the same criteria. Again, you should consult with legal counsel in the event you decide to take disciplinary action against an employee as a result of any findings contained in his or her MVR.

Additional factors to consider

A driver’s age may be a contributing factor in vehicle accidents. For example, a youthful operator may possess a clean record; however, because the individual has been licensed a relatively short time, his or her driving experience may be limited.

On the other hand, long term “good” drivers may develop adverse trends over time. You should, therefore, conduct MVR checks on all drivers at least once annually. Again, you should make this periodic check a condition of employment and should obtain written authorization from your employees to do so.

How to obtain MVRs

State Departments of Motor Vehicles (DMVs) are good sources for Motor Vehicle Records. Our Risk Solutions Partner SambaSafety can help support your screening efforts.

Some states offer a service that allows businesses to receive automatic notifications of changes to their drivers' MVRs. This is an excellent way to provide immediate intervention and counseling of drivers rather than waiting for an annual MVR review.

Sample MVR program guidelines

Major violations — One makes driver unacceptable:

• Negligent homicide within last five years
• Criminal‐type conviction within last five years
• Hit‐and‐run within last five years
• Manslaughter within last five years
• Suspended or revoked license — currently suspended or revolved
• Drag racing within last five years
• Driving under influence/impaired within last five years

Moving violations

• Reckless driving within last five years
• Careless driving within last three years
• Assault involving a motor vehicle within last five years
• Passing a stopped school bus within last three years

Unacceptable*

• Three or more moving violations within the last three years
• Two or more at‐fault accidents within the last three years
• Violations and accidents combined: More than one at‐fault accident and 1 moving violation within the last three years when not the same incident

Moving violations

• Speeding violations
• Improper or excessive lane changes
• Following the vehicle ahead too closely
• At‐fault accidents (any accident where the driver is cited with a violation, or negligently contributes to the incident OR; any single‐vehicle accident that is not caused by actual equipment failure)
• Running a red light or stop sign
• Failure to yield

Acceptable

• The driver has violations but does not meet the MAJOR or UNACCEPTABLE criteria

Clean

• No violations listed on the MVR

Please note this list is not all inclusive, but a general guideline of the types of violations that fall into “Major Violations” and “Unacceptable”. The actual wording of a violation varies by state.

*Not‐at‐fault accidents, failure to wear seat belts, failure to register vehicle, failure to maintain vehicle, improperly marked or secured loads, oversize/overweight violations, non‐compliance with financial responsibility laws, and other non‐moving violations may also be considered unacceptable. Multiple incidents of these types of violations may indicate a general disrespect for safety controls and laws.

Determine the optimal viewing height and distance for your monitor.

• If you have a nice workstation set up, but find that you experience fatigue in your head and shoulders, your monitor may be in the wrong place for you. To minimize upper body fatigue your monitor should be at the correct height and distance for you. How do you determine this?
  1. Pull up some typical viewing material on your monitor screen. This may be a spreadsheet or other type of document.
  2. Position yourself at your workstation.
  3. Close your eyes. Roll your head around to relax and let your head find a natural and comfortable position.
  4. Open your eyes.
• What happened? If you have to raise or lower your chin to see the monitor screen, the existing viewing height may not be right for you.
• If you lowered your chin after step four, the monitor may be too low. Monitor blocks or a monitor stand may be needed.
• If you raised your chin after step four, the monitor may be too high. Lowering the monitor may help.
• Make adjustments and repeat steps one to four.
• You may want to try moving the monitor forward and backward on the work surface to fine tune viewing conditions. Repeat steps one to four as needed. This is especially important for individuals who wear multi-focal-length lenses.
• Finally, move around periodically. Ergonomists tell us that changing positions can ease muscle tension and minimize fatigue. Ideally, variety in the workday provides these whole body motions to complement static seated work postures.
