Five tips for protecting employees in construction work zones
Each year, many workers are injured and killed while performing highway and street construction. Most of these injuries and fatalities occur in what is known as the “work zone.” The work zone is an area where highway construction, maintenance, or utility work activities take place. What makes this area dangerous is passing motorists, construction vehicles, and equipment are moving through the same space that the construction employees are working in.
#1 Understand what causes accidents
Accidents that occur in work zones are often caused by:
- Poor traffic control procedures,
- Unsatisfactory construction vehicle and equipment maintenance (such as malfunctioning warning devices),
- Poorly designed work zones, and
- Failure to establish and follow policies and procedures for ensuring safety on the job.
Vehicles and equipment operating in and around the work zone are involved in over half of the worker fatalities in the heavy and highway construction industry.
Sometimes passing motorists are at fault for the injuries and fatalities that occur in the work zone when they mistakenly enter it. Other times, it’s the construction vehicles and equipment operating within the work zone that causes the accidents and injuries.
#2 Know the work zone hazards
There are two types of work zone hazards:
- Internal hazards are activities within the workspace, such as moving vehicles.
- External hazards are presented by passing cars and trucks, and the debris they kick up.
Potential hazards in work zones include:
- Traffic and construction equipment accidents,
- Working above level,
- Slippery conditions,
- Machinery pinch points,
- Crush zones,
- Drop-offs,
- Trenches,
- Airborne lead and silica particles,
- Truck tip-overs, and
- Energized electrical lines and conductors.
#3 Train all personnel
Train all personnel, including visitors, on each work zone’s hazards and how to avoid them. NIOSH suggests training on topics such as:
- Recognizing, eliminating, or avoiding hazards involving equipment,
- Knowing the locations and sizes of blind spots around equipment,
- Knowing the hazards and protective measures associated with working at night, and
- Understanding communication methods and alarms.
#4 Provide equipment operator training
OSHA requires operators to be trained on the equipment and machines they’ll operate. Make sure the training includes instruction on:
- How to avoid rollovers;
- Information on the clearances that must be maintained between vehicles;
- Hazards such as unstable surfaces, trenches, excavations, and overhead utility lines; and
- Instruction on the location, size, and configurations of blind spots and how to minimize their potential for contributing to accidents.
#5 Review your existing work zone safety procedures
It’s always a good idea to review all your safety procedures on a regular basis. The same is true for you work zone safety procedures, so look at them to see if they can be improved.
Key to remember
Construction employees face internal and external work zone hazards. You can protect them by establishing a safe work zone, recognizing potential hazards, and providing proper training. Review your existing work zone safety procedures to see if they can be improved.
