General Precautions
Workers struck by vehicles or mobile equipment account for many fatal work zone injuries. Work zones need traffic controls identified by signs, cones, barrels and barriers.
Drivers, workers on foot and pedestrians must be able to see and understand the proper routes.
Construction project managers should provide traffic control plans within construction/
demolition worksites.
Traffic control devices, signals and message boards should instruct drivers to follow paths away from where work is being done.
Approved traffic control devices, including cones, barrels, barricades and delineator posts, are also used inside work zones.
Work Zone Protections
Various concrete, water, sand, collapsible barriers, crash cushions and truck-mounted attenuators can help limit motorist intrusions into construction work zones.
Training
Flaggers must be trained/certified and should use authorized signaling methods.
Driving
- Seat belts and rollover protection should be used on equipment and vehicles as recommended by the manufacturer.
Flagging
Flaggers should wear high visibility clothing with a fluorescent background made of retroreflective material.
High visibility clothing makes workers visible for at least 1,000 feet in any direction. Check the label or packaging to ensure that the garments are performance Class 2 or Class 3.
Drivers should be warned with signs that there will be flaggers ahead.
Flaggers should use STOP/SLOW paddles, paddles with lights, or flags (only in emergencies).
