Office Safety Tips

In municipal government, labor-intensive jobs in public works, law enforcement and emergency services, are the source of most work-related injuries. But, are you aware that employees who work in office settings are also at risk of suffering disabling injuries? The injuries may look different, but they still cause pain, cause expensive workers’ compensation claims, and reduce overall productivity. Office workers deserve a spotlight on how to stay safe and healthy at work.

Employees may feel safe in the comfort of their office, but that’s where the dangers are. Poor ergonomics and organization can lead to three common office injuries – repetitive use injuries, computer eye strains, and falls. Here’s what you need to know about these injuries and how you can avoid them to make the office a safe workspace.

Repetitive Stress Injuries

A Repetitive Stress Injury (RSI) or overuse injury is caused by repeating the same motion for extended periods and RSIs affect millions of workers every year. In an office setting, extended periods of sitting and computer work without proper ergonomics can cause strain on the back and upper extremities, wrists, elbows, and hands.

Employees who perform repetitive activities are at risk of developing carpal tunnel syndrome, a common RSI. Carpal tunnel syndrome causes swelling in the wrist that puts pressure on the nerves and causes pain, tingling, and numbness. Also, prolonged sitting can lead to different posture problems, like strained neck and shoulders or lower back pain. While these may seem like small injuries, they can cause a lot of pain and make work difficult. As they get more severe over time, these RSIs can potentially require long-term physical therapy and rehabilitation.

The best way to avoid these injuries is by preventing them with ergonomic workstations. Ergonomics is the study of how people interact with their physical environment. You can maximize productivity and minimize injuries by building the physical environment around a person, or fitting a workspace to an employee, rather than forcing an assorted-sized workforce to all fit within the same dimensions.

For example, consider a 5-foot-tall employee using the same chair settings as a 6-foot-tall employee. The shorter worker could have tension in their back and thighs if their feet can’t rest comfortably on the ground, and the taller worker could strain their neck having to look down at the computer monitor. Different workers have different needs.

To get started on improving ergonomics, follow these guidelines:

·         Provide adjustable work stations that allow employees to alternate between seated and standing positions

·         When working at a computer, keep wrists in a neutral position, elbows by your side, shoulders back, and sit up straight

·         Keep regularly used items, like the telephone and calculator, within easy reach

·         Adjust your chair so your feet rest firmly on the floor with your knees bent at 90-degree angles

·         Position your computer monitor directly in front of your head, just at or slightly below eye level

Along with these ergonomic guidelines, encourage employees to take frequent breaks to stand, walk around, and stretch their hands and wrists.

Computer Eye Strain

With the average U.S. worker spending seven hours a day on the computer, not to mention personal time staring at phone screens, eye strain has become a common injury for office workers. A survey from the American Optometric Association reported that 58% of adults have experienced eye strain or vision problems as a direct result of too much screen time.

Symptoms of computer eye strain include headaches, blurred vision, dry eyes, eye twitching, or even physical fatigue and increased number of work errors. Most office employees rely on computers to complete their work, so you can’t get rid of computers to fix this problem. However, there are several adjustments workers can make to reduce eye strain and improve productivity.

These adjustments include:

·         Cover windows or close the blinds to reduce excessively bright light coming from outside

·         Use fewer light bulbs or lower intensity bulbs to reduce excessive indoor brightness

·         Position computers to the side of a window rather than in front of or behind it

·         Adjust the brightness of the computer display to match the brightness of the surrounding workstation

·         Alter text size and contrast for comfort

Employees should also take breaks away from the computer to avoid eye fatigue. One common method encouraged by eye doctors is the “20-20-20 rule.” Every 20 minutes, workers should turn their gaze to an object that’s 20 feet away for at least 20 seconds. This rule relaxes the muscles inside the eye. A recent study by the National Institute for Occupational Safety and Health (NIOSH) found that these breaks not only significantly reduced eye strain, they also increased work productivity.

Slips, Trips, and Falls

According to the National Safety Council, slips and trips account for the greatest number of work-related injuries in offices. The Centers for Disease Control and Prevention (CDC) adds that office workers are two to 2.5 times more likely to suffer a disabling injury from a fall than non-office workers.

While falls are usually just accidents, they are preventable. Clear work areas, proper lighting, and promptly cleaned up messes can help prevent most workplace falls. The CDC states that the most common causes of office falls are:

·         Tripping over open drawers, electrical cords, loose carpeting, or objects in walkways

·         Reaching for something while seated in an unstable chair

·         Standing on a chair instead of a ladder

·         Slipping on wet floors

·         Not being able to see due to inadequate lighting

Employers can reduce the $70 billion spent annually on workers’ compensation and medical costs for falls by encouraging employees to follow some simple tips:

·         Don’t place objects in common walking paths

·         Close file and desk drawers when you finish using them

·         Get up to reach something rather than trying to reach from your chair

·         Secure electrical cords and loose carpeting

·         Clean up spills on the floor (even if you didn’t make the mess), or place caution signs over spills until they’re cleaned up

·         Use stepladders instead of chairs to reach items overhead

Although work-related injuries in an office setting can be severe, they’re also mostly preventable. So, start making your office a safer place by following these simple tips and educating your workforce.

Preventing Falls

Falls continue to be the second leading cause of death to workers. To help reduce fall-related injuries and fatalities, OSHA advises employers to “plan, provide, and train” their workers who work at heights of 6 feet or more (bucket truck, water tower, utility vault, etc.)  These situations require a plan for safety and emergency retrieval and the proper equipment for performing work tasks at height. Workers need to be properly trained to understand the hazards, and how to control them through administrative controls, engineering controls, and personal protective equipment (PPE).

Plan – When planning a job that requires working from height, the employer is responsible for ensuring the work can and will be done safely. When planning for the budget, employers must include the cost involved for purchasing the proper safety equipment to perform elevated tasks. They must plan to have the necessary equipment available and used at the job site.

Provide – Employers must provide fall protection and related equipment (ladders, scaffolds, safety harnesses, etc.) for employees working 6 feet or more above a lower level. If workers use personal fall arrest systems for work in trees or bucket trucks, a harness for each worker who needs to tie off to an anchor must be provided. Each system must properly fit the worker and be inspected regularly. Purchase equipment from reputable vendors that provide hands-on training on their equipment.

Train – Every worker must be trained on the proper set up and safe use of their fall protection system and they must be deemed proficient by their supervisor before doing hazardous work at height.

When working with ladders, workers should know to maintain 3 points of contact (2 hands and 1 foot or 2 feet and 1 hand) on the ladder at all times. Keep ladders on a level surface, secure ladders by locking their metal braces, and avoid over-reaching when performing tasks outside the ladder edges. As for working on scaffolds, a worker must know how to safely set up the scaffold including how to set up guardrails and ensure stable footing can be maintained. The scaffold must be set up level. The scaffolding should be inspected by a supervisor before workers are allowed to use it.

For off or below ground work, the workers need to make sure their harness fits properly, straps are sufficiently backed up, and they are securely tied off or belayed at all times. Workers should be able to check that their anchor points are secure and make sure any openings are protected or covered.

Working at heights is a very serious situation - don’t under estimate the danger. Falls from heights are low in frequency but high in severity. This kind of accident could be catastrophic for a worker and your municipality.

Preventing Worker Deaths from Trench Collapse

Trench collapse accidents are rarely survivable. OSHA statistics reveal fatalities caused by trench wall collapse are increasing. This trend is preventable by complying with OSHA standards that every municipal utility service employee should know. Municipal employees who dig or excavate trenches are at risk of death if they enter an unprotected trench and the walls collapse.  

Hazards associated with trench work and excavation are well defined in the OSHA standard for excavation and trenching found in 29 CFR 1926.651 and 1926.652 Subpart P. It describes the precautions needed for safe excavation work. There is no reliable warning when a trench fails. The walls can collapse suddenly, and workers will not have time to move out of the way. Even though small amounts of dirt may not seem dangerous, a single cubic yard of dirt can weigh more than 3,000 pounds, which can fatally crush or suffocate workers. Even small, solid pieces of dirt can cause serious injuries.

Most incidents involve excavation work on water, sewer, pipeline, communications and power-line maintenance, repair, and/or construction. OSHA data shows that most fatalities in trenches occur at depths of 10 feet or less. Lack of a protective system was the leading cause of trench-related fatalities.

OSHA requires all trenches 5 feet deep or more use one of the following protective systems:

  • Sloping the trench walls
  • Benching the trench walls
  • Shoring the trench with pneumatic or hydraulic jacks and trench plates
  • Shielding the trench using a trench box

Workers should never enter a trench that does not have a protective system in place designed and installed by a competent person. Factors such as type of soil, water content of soil, environmental conditions, proximity to previously backfilled excavations, weight of heavy equipment or tools, and vibrations from machines and motor vehicles can greatly affect soil. Not all protective systems can be used in all types of soil. A competent person is one who understands OSHA regulations, can recognize hazards, and is authorized to correct them.

Employer Responsibilities

Call 811 before digging so that utility lines can be marked.  Train and designate a competent person to ensure safety measures are in place. What is a competent person? A competent person is an individual who can identify existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to workers, and who is authorized to take prompt corrective measures to eliminate them.

Competent Person Responsibilities

  • Classifying soil
  •  Inspecting protective systems
  •  Designing structural ramps
  •  Monitoring water removal equipment
  • Conducting site inspections
  • Planning the job layout to identify safe locations for spoil piles and heavy equipment routes
  • Determining what type of protective system will be used for the job and scheduling the steps needed to have the system complete and in place before workers enter
  • Ensuring that employees are trained to spot signs of imminent trench collapse, including tension cracks, bulging, and toppling
  • Developing a trench emergency action plan to describe steps to be taken and to provide contact information in case of an emergency
  • Ensuring that ladders and other means of exit from the trench are repositioned so that ladders are never more than 25 feet away from any worker in the trench
  • Must remove workers from the excavation upon any evidence of a situation that could cause a cave-in, such as accumulation of water in the trench or protective system problems
  • Take actions for other types of hazards such as falling loads or hazardous atmospheres
  • Monitor other types of trench–related hazards that can occur such as falls from the edge, rigging hazards, or toxic and combustible gases
  • Implement and enforce procedures to ensure that work in an unprotected trench is not allowed

Workers

  • Do not enter an unprotected trench, even for a short task
  • Inspect the protected trench before entering
  • Exit the trench and call the competent person if you see any evidence of problems with a protective system
  • Do not assume there will be a warning sign before a cave in or that you will have time to move out of the way
  • Manually uncover utilities to determine the exact location and depth before mechanical digging with a backhoe or trackhoe

Do you ever work in a confined space?

Do you ever work in a confined space? There are many types of confined spaces – tanks, silos, pits, tunnels, pipes, boilers, sewer manholes, trenches, etc. No matter what the type, confined spaces have something in common. They have limited ways to get in and out, and the atmosphere within them could be dangerous. 

A confined space has three characteristics: 1) It has limited openings for entry and exit, 2) it is large enough to permit a worker to enter, and 3) it is not designed for continuous worker occupancy. The characteristics of a confined space cause it to present unique hazards. Early miners knew some of the dangers of a confined space. Have you ever heard about the canary that died? Miners took a bird into the mine. When the bird died, the miners knew the atmosphere in the mine was getting dangerous. The death of the canary told miners it was time to leave. Today we have more sophisticated ways of testing the atmosphere in confined spaces, but the principle is the same. Check the atmosphere to make sure it is safe to work in before you enter a confined space. 

Confined spaces present many dangers – some of which the miners of yesteryear never knew. Here are some common confined space hazards: 

•    Lack of oxygen, presenting a suffocation hazard

•    Fire or explosion hazards from an accumulation of flammable vapors

•    Health hazards from toxic vapors

•    Difficulty exiting the space in the event of an emergency

•    Cramped spaces to work in, resulting in a danger of being caught in/on equipment  

•    Poor visibility

•    High levels of noise

•    Temperature extremes

Regulatory agencies require workplaces to have a plan for working in confined spaces safely. If you work in a confined space, you should know your municipality’s procedures for safely entering the space and working in it. Confined spaces should be identified and classified, and safe entry procedures developed. Some confined spaces are called “permit-required confined spaces,” meaning a permit is required for entry into the confined space. In addition to the normal characteristics of a confined space, permit-required spaces present one or more of these hazards: 

•    Has the potential to contain a hazardous atmosphere

•    Could contain material capable of engulfing someone entering the space

•    Has an internal configuration such that a person could be trapped or asphyxiated by inwardly converging walls or by a floor which slopes downward and tapers off to a smaller cross-section (i.e. grain elevator) 

•    Contains any other recognized serious hazard

In general, these are the things you should be aware of before you enter a confined space: 

•    Know how to enter it safely

•    Know how to exit quickly

•    Know that the atmosphere in the space is tested and found to be free of dangerous levels of toxic or flammable vapors, and that there is sufficient oxygen

•    Know that the atmosphere within the space is going to remain safe while you are working

•    Know the rescue plan in the event of an emergency, and make sure the proper rescue equipment is available and in good condition

•    Know that another person outside the confined space is keeping an eye on you as you work, and that they know the rescue plan also

•    Know what other procedures are necessary to follow to work safely, such as locking out energy sources

Another very important thing to remember is what to do if someone working in a confined space becomes ill or injured. In the event of such an emergency, you should never enter a confined space to rescue someone without the proper equipment, training, and atmospheric testing. Chances are, whatever caused the illness or injury will get you too! Many confined space accidents claim the lives of multiple victims because the initial ill or injured person is a friend and co-worker. People often react to the situation with poor judgment - they just see their friend is in need and jump in to help them without thinking about the danger to themselves. The next thing you know they succumb to the hazard. 

It is possible to work safely in confined spaces, but it is a task that requires careful planning and preparation. Don’t be tempted to take shortcuts when it comes to confined spaces. Follow all safety precautions and don’t hesitate to speak up if you are unsure of the correct procedures. You play the most important role of all when it comes to working safely. By consistently following safe work procedures and not taking chances, you will be working safely for a long time to come.

Keeping Solid Waste Workers Safe

It’s dangerous to be a “Trash Man”. According to the Solid Waste Association of North America, there were 7 fatalities to sanitation workers in the first 10 days of 2018.  In addition, the Bureau of Labor Statistics has determined that refuse and recyclable materials collectors have the 5th highest fatal work injury rate among civilian occupations. Then there are the non-fatal injuries; sprains, strains, and over-exertion injuries in solid waste collection are 10 times more likely, due to jumping on/off trucks, handling heavy loads, and being backed over by drivers. Exposure to potentially dangerous materials is another major concern in the solid waste industry.

Although OSHA regulations don’t expressly govern sanitation employees or vehicles, it does inspect industrial employers if fatalities occur. The American National Standards Institute (ANSI) has published Safety Standards for Mobile Refuse Collection and Compaction Equipment, a group of procedures that offers worker guidance:

·        Ride only in the vehicle cab or on steps specifically designed for riding

·        Remain inside the vehicle cab until the vehicle is completely stopped

·        Ensure workers are not using riding steps when the vehicle is backing, exceeding 10mph, or traveling more than 2/10th ‘s of a mile

·        Ensure no one rides on the loading sills or in hoppers

·        Wear personal protective equipment, high visibility vests, and/or outerwear

·        Never use cellphones while driving trucks or at a disposal facility

·        Always wear a seatbelt

Equipment makes a difference.  Garbage trucks with automated side-loader systems enhance sanitation worker safety by limiting exposure to hazards outside the truck, as well as those associated with heavy lifting. The same worker can drive the truck and operate the mechanical side arm, which collects refuse containers, dumps contents into the truck and returns the container to the ground. The automated side-loader, from an equipment standpoint, has made a huge difference to worker hazard exposure. No more manual lifting, no being exposed to hazardous waste, and no more being hit by vehicles in the roadway.

Some workers, however, still manually load garbage into trucks despite the emergence of more widespread automated collection. Municipalities may want to establish weight limits for garbage, but these must be rigorously enforced. Workers don’t know by looking at a bag how heavy it is until they lift it. The contents of the bag may not immediately be apparent, putting workers at risk of chemical or bio-hazards.

Many garbage trucks these days are equipped with rearview cameras and other technology to augment the mirrors on both sides of the truck. It should be stressed to drivers to look back and forth between mirrors and cameras when driving and backing the vehicle, to establish good awareness of the environment and to be sure they know where ground workers, other people, vehicles, buildings, and other hazards are at all times. Although maintaining focus remains the goal of drivers, industry experts find that complacency can still develop. There is truth to the concern that workers will become complacent and distracted after having done the same thing day after day, week after week, month after month, without anything bad happening. That is why we need to train and retrain on safety and communicate why it is important and everybody’s job. In addition, drivers should participate in extended training on a Focus 6 Program, designed to help them maintain the skills to eliminate the six most frequent types of sanitation industry incidents: backing, rollover, rear collision, intersection, pedestrian/bicycle, and push-pull-and lift.

Although hazards are also present during post-collection operations at landfills, transfer stations, and recycling centers, these are more fixed facilities and the hazards are more defined and can be adjusted. Observing people is easier because of the controlled environments at these facilities.

Communication between workers and supervisors is a key element to sanitation safety. Supervisors should remain aware of new techniques and industry standards by subscribing to waste management periodicals. It takes collaboration, leadership, and teamwork to make the industry safer.

Is 911 your confined space rescue plan? If so, here's what you should know.

The dangers of confined space work have been written about since Roman times, when the Emperor Trajan was noted to have sentenced criminals to clean sewers, an occupation considered one of the worst.  Working conditions have improved vastly since Trajan’s time, but the same hazards persist and result in workplace injuries and fatalities each year.  According to the Bureau of Labor Statistics nearly 100 work fatalities occur in permit-required confined spaces.  In addition, for every victim who dies in a confined space, 3 would-be rescuers lose their lives trying to rescue a victim. 

Even though you’ve met all the requirements for a safe confined space entry: you have an attendant, an entrant, and a supervisor, you have the space clearly marked and protected as a confined space, you are monitoring atmospheric conditions, you’ve made sure the entrant has a harness, tripod, tag-line and winch in place, and you have a correctly completed confined space entry permit, you aren’t done.  The only requirement remaining is completion of the rescue plan.  Most municipalities usually complete the rescue plan by writing “CALL 9-1-1.” That is not sufficient.

Relying solely on 9-1-1 as your means of emergency rescue is essentially planning for a body recovery, not a rescue.  To prevent injuries and fatalities, the Occupational Safety & Health Administration (OSHA) requires a specific plan of operation for confined space rescue. These operations must be established by the employer (municipality)¹. If 9-1-1 is part of your emergency plan, the employer is to, among other things, do the following:

·         Evaluate the emergency responder’s ability to respond in a timely fashion

-          OSHA expects emergency care to be administered to the victim in 3-4 mins²

·         Ensure the responder has the equipment and training to enter the specific confined space you are working in

-          Even though you are in a small community and the fire station is just around the corner, that doesn’t necessarily mean that your local firefighters have the training and equipment to respond to a confined space rescue

·         Ensure the responder is proficient in performing the needed rescue services

-          OSHA standards require that the owner of the confined space ensure that the emergency responders are proficient at conducting rescues from the specific types of spaces

-          OSHA lists 24 types of confined spaces depending on the size of the opening, shape of the opening, and location with respect to the space

-          The OSHA term “Proficient” means the employer has certified the responder as being proficient in conducting rescues from the specific type of confined space encountered

Municipalities, like private employers, have two options when considering permit-required confined space rescue, since for most, “9-1-1” is not a viable option for emergency confined space response and rescue operations. 

-          Train your employees to conduct permit-required confined space rescue operations and provide medical assistance, or

-          Hire a third-party Rescue and Response company to provide those services for your municipality.

Who Is "At Risk" in a Work Zone?

Each year in the US, hundreds of workers are killed or seriously injured when vehicles crash through traffic control devices and enter a work zone. Workers are also struck by equipment operating within the work area. Whether it’s repairing streets, cleaning storm sewer catch basins, painting intersections, or rebuilding manholes, tasks that require workers to share the road with vehicles put them at risk.

Preventive Measures:

A traffic control plan must be developed before the work begins to guide drivers through and around work zones. The traffic control plan must include:

·         Advanced warning to drivers of the work being done ahead

·         Placement of traffic control devices to clearly mark the work zone and channel traffic through it

·         A return to normal traffic patterns as quickly, safely, and efficiently as possible

The traffic control plan must address these factors:

·         The type of roadway (number of lanes, divided or undivided highway, etc.)

·         Traffic volume and speed (approximate number of vehicles passing through and the speed of vehicles)

·         Type of work to be done and how long it will last (pothole repair, fix a broken water line, roadway line painting, etc.)

·         Type and number of traffic control devices and signs needed to make the work zone safe

Creating a buffer zone between workers and traffic is the best way to protect them. Set up detours or use barriers such as type 3 barricades or concrete barriers, which protect workers much better than cones or barrels.

Reducing the speed of traffic in work zones also provides a safer work environment for workers. Put down portable rumble strips or using a pilot car to guide traffic at reduced speeds through the work zone area.

Advanced Warning Signs should be located far enough in advance to allow vehicles to move efficiently and smoothly through work areas. They must clearly inform motorists of approaching activity and guide drivers through that activity.

All advanced warning signs must be:

·         Orange background with black lettering or symbols

·         Retro-reflective or illuminated if used after dark

·         4x4 feet if traffic moves at 45 mph or faster

·         3x3 feet if speeds are 40 mph or slower

·         7 feet above the road surface (measured to the bottom of the sign)

·         At least 1 foot above the road surface if the sign is portable

·         Less than 50% of the top two rails or not more than 33% of all rails if mounted on a barricade

Advance warning signs should be placed so as to give motorists enough time to react to the conditions they will find ahead of them. In general, the distance between the first warning sign and the work area should be increased the faster traffic is moving (Example: less than 40 mph = advanced warning sign 300 feet ahead; more than 45 mph = advanced warning sign 500 before work zone with at least 2 signs before entering work zone; add 100 feet for every 5 mph over 45 mph).

Traffic Control Devices such as cones, drums, barricades, tubular markers, and pavement markers are commonly used to alter or channel normal traffic flow. They alert drivers of work activities ahead and provide smooth and gradual traffic movement from one lane to the next. Cones, drums, and other devices must be made of lightweight materials and give way when struck by a vehicle. They must not break apart or be capable of penetrating the passenger compartment of a vehicle. The material used to weigh down devices (ballast) to prevent them from being easily blown over must also be made of materials that will cause only minimal damage to vehicles. Drums must be at least 3 feet tall and 18 inches wide, they must be orange and have 2 white alternating retro-reflective stripes. Stripes must be between 4 to 6 inches in width. The tops of the drums must be closed to prevent accumulation of debris. Steel drums are prohibited.  Barricades are of 3 types and can be portable or fixed: Type 1 must be at least 3 feet tall with one rail 2 feet in length; Type 2 must be at least 3 feet tall with 2 rails 2 feet in length; Type 3 must be at least 5 feet tall, have 3 rails at least 4 feet long. The rails on all 3 types must be between 8 and 12 inches wide. They should be equipped with warning lights and the lights should be either steady burn or flashing. The stripes on barricades must be alternating orange and white with reflective striping. The stripes should slope down at a 45-degree angle in the direction traffic is moving. Striping should be at least 4 inches wide (If the rails are more than 3 feet long the stripes should be 6 inches wide.) There should be a minimum of 270 square inches of retro-reflective tape for on-coming traffic.

Laws to Protect Workers

The US Department of Transportation and the Federal Highway Administration have issued the Manual on Uniform Traffic Control Devices (MUTCD). OSHA enforces the MUTCD and it is part of OSHA’s standards for the construction industry (29 CFR 1926.200, 29 CFR 1926.203). For state and local workers not covered by OSHA, the Department of Transportation requires that the standard be followed on all public roadways.

It is the municipality’s responsibility and duty to comply with these standards to protect both workers performing duties in and on roadways, as well as drivers and pedestrians using those roadways.

Work Zone Safety According to OSHA

Traffic incidents and workers struck by vehicles or equipment account for the highest number of fatal work injuries in America according to the Bureau of Labor Statistics. Emergency responders, clean-up crews, utility workers, and construction workers working in areas where there are moving vehicles and traffic are exposed to being hit by a moving vehicle. Work zones are used to move traffic in an approved direction and are typically identified by signs, cones, barricades, and barriers. Municipal workers and citizens are to be protected by planning work zones (areas where construction and maintenance are being conducted) and using the proper protective and communication devices.

There must be a traffic control plan for the movement of vehicles in areas where there are workers conducting other tasks. Drivers, workers on foot, and pedestrians must be able to see and understand the routes they are to follow. The authority in charge (federal, state, or local) will determine the internal traffic control plan within the construction worksite. When there are several projects, coordinated vehicle routes and communication between contractors will reduce incidents where people are struck by a vehicle.

Standard highway signs for information, speed limits, and advanced warnings for work zones will assist drivers in identifying such directives as “do not enter”, “road/lane closed”, and “reduced speed”. Using standard highway signs for construction or maintenance work sites will assist workers in recognizing the route they are to use at the work site.

Standard traffic control devices, signals, and message boards will instruct drivers to follow a path away from where work is being done. The authority in charge will determine the approved traffic control devices such as cones, barrels, barricades or candlestick posts that will be used as part of the traffic control plan. Use these same types of devices inside the work zone.

Various styles of concrete, water, sand, collapsible barriers, crash cushions, and truck mounted attenuators should be used to limit motorist intrusions into a construction work zone.

Flaggers and others providing temporary traffic control must wear high visibility clothing with a background of fluorescent orange-red or yellow-green and retroreflective material of orange, yellow, white, silver, or yellow-green. In areas of traffic movement, this personal protective equipment (PPE) will make a worker visible for at least 1,000 feet, so the worker can be seen from any direction, and make the worker stand out from the background. Make sure to check labels or packaging to ensure the garments are performance class 2 or 3.

Drivers should be warned in advance with signs that there will be a flagger ahead. Flaggers should use STOP-SLOW paddles with reflectorized panels. The STOP side should be octagonal in shape and be red with white letters, the SLOW side should also be octagonal shaped with orange coloring and black letters.

Flagger stations should be illuminated. Lighting for workers on foot and equipment operators is to be at least 5-foot candles or greater. Where available lighting is not sufficient, flares or chemical lighting should be used. Glare affecting workers and motorists must be controlled or eliminated.

Flaggers should be trained/certified and use the signaling methods required by the authority in charge. Workers on foot, equipment operators, and drivers in internal work zones need to understand routes that construction vehicles will be using. Equipment operators and signal workers need to know the hand signals used for the work site. Operators and workers on foot need to know the visibility limits and “blind spots” for each vehicle on site. Workers need to be made aware of the ways shiftwork and nightwork may affect their performance.

Finally, seatbelts and Rollover Protections Systems must be used on equipment and vehicles in and off the work site.
