In 2010, 576 people died in work zone crashes, an average of one fatality every 15 hours. Here’s what OSHA requires for keeping construction site workers, drivers, and pedestrians safe.

Delineate the proper route: Use concrete, water, sand, collapsible barriers, crash cushions, and truck-mounted attenuators to direct drivers away from the jobsite.

Clothe employees correctly: Workers wearing fluorescent, retroreflective material should be visible for at least 1,000 feet in any direction. Check the label or packaging to ensure garments are performance class 2 or 3.

Protect flaggers: Use signs to warn drivers there will be flaggers ahead. Flaggers should use STOP/SLOW paddles, paddles with lights, or flags.

Lighting: Illuminate flagger stations. Lighting for employees on foot and for equipment operators should be at least five foot-candles; where that’s not possible, use flares or chemical lighting. Control and/or eliminate glare.

Training: Flaggers must be trained/certified and use authorized signaling methods.

Driving: Follow manufacturer recommendations for seat belt and rollover protection use.
