Traffic isn’t the only threat to workers in construction zones
OSHA 29 CFR 1926 Subparts G and O are intended to protect workers in highway construction zones from injury, especially from the movement of construction vehicles and passing motorists. But what about other hazards to which these workers are exposed?
In 2022, Zanesville, Ohio, emergency response personnel were called into action to rescue a 43-year-old road construction worker who had gotten trapped in an auger. The worker was part of a crew performing boring activities under and around the highway. The incident could have been prevented and is a stark reminder that traffic isn’t the only threat to highway and road work zone employees.
Work zone hazards
The Bureau of Labor Statistics (BLS) reports fatal injuries to road construction workers averaged 123 per year from 2003-2020. Workers being struck by vehicles is the most prevalent hazard, especially when work is being performed along busy highways. Workers may also be involved in crashes within the work zone. However, these aren’t the only hazards road workers face. Highway and road work hazards include:
- Struck by vehicles or equipment. The Federal Highway Administration (FHA) reports that the number of deaths from crashes in work zones has increased an average of 794 from 2015-2020. Workers were not only struck by forward-moving vehicles, but by backing vehicles, semi-trucks, dump trucks, and heavy equipment. Flaggers are especially at risk of injury from vehicle incidents.
- Caught in or between equipment. As with the Zanesville worker, road workers can get caught in or between augers, heavy equipment, conveyors, and other construction equipment. They may also be caught between work vehicles and heavy machinery if they aren’t visible to vehicle operators. Additionally, workers may be caught in vehicles that have overturned while working on steep embankments or are being loaded on/off trailers.
- Falls and falling objects. Workers could fall from heavy equipment, scaffolding intended to reach overpasses, or from flatbed trailers. Heavy equipment operators are at risk of being struck by falling objects as well, such as dirt falling from a bucket or equipment dropped from a crane.
- Electrical. Electrical hazards include direct exposure to electrical wires as well as indirect exposure when operating a crane that contacts a power line.
- Burns. In addition to potential burns from contact with electrical power lines, workers are also exposed to gas pipelines, hot asphalt, or equipment that could catch fire or explode.
- Musculoskeletal disorders (MSDs). Work zone warriors are required to bend, twist, lift, and handle machinery such as jackhammers. All of these are ergonomic stressors that can lead to fatigue and potentially long-lasting MSDs.
- Extreme temperatures. Work zone construction rarely takes a rest from the heat of the summer or the frigidity of the winter. Workers are susceptible to heat and cold exposures that can lead to injuries and illness if hazards aren’t mitigated.
OSHA isn’t the only agency that sets out to protect road workers. Employers should ensure compliance with local and state agencies, the Department of Transportation (DOT) and the National Transportation Safety Board (NTSB) requirements. Careful consideration should be given to National Institute of Occupational Safety and Health (NIOSH) and the American National Standards Institute (ANSI) recommendations as well since OSHA often refers to them.
What can employers do to protect workers from all work zone hazards?
- Understand and ensure compliance with all work zone safety regulations.
- Implement an internal traffic control plan (ITCP) to address chain of command, equipment and personnel on site, shift work, work zone layout, emergency response plans, traffic control, etc.
- Ensure work zone layouts don’t place workers in the line of fire of equipment, traffic, or other hazards. For example, close the road completely and redirect all traffic and give motorists sufficient warning to reroute. Whenever possible, separate workers on foot from equipment.
- Utilize temporary traffic and speed control devices.
- Implement extensive training for equipment operators, workers, and flaggers.
- Provide proper personal protective equipment (PPE) including cold and warm weather wear, as well as high visibility clothing. Require high visibility clothing be worn when entering, exiting, or working within the work zone. Such clothing must be maintained so color is not faded, reflective properties are still visible, and clothing isn’t covered with mud, oil, or other debris. High visibility clothing shouldn’t be limited to vests. Consider gloves, hats, and other articles.
- Provide adequate lighting for the work zone, while controlling glare for workers and motorists.
- Ensure workers maintain constant visual and verbal communication with one another.
- Verify all equipment and tools are inspected and maintained in safe working condition.
- Confirm workers are trained and certified to perform their work and operate equipment assigned to them.
Did you know?
The Alliance, an OSHA Cooperative Program, works with OSHA, NIOSH, and the Roadway Work Zone Safety and Health Coalition to provide members, government, and non-government with resources and guidance for helping protect workers from roadway work zone hazards.
Goals of the Alliance include:
- Developing hazard awareness training and education on work zone safety.
- Fostering outreach and communication for EHS professionals and other professions aimed at improving work zone safety.
- Promoting a national dialogue on workplace safety to raise awareness.
- Demonstrating leadership commitment through informative forums, innovation, and teamwork.
Key to remember
Employers and road workers must work together through planning and training to minimize all work zone hazards, not just traffic collisions.
