Traffic Cone and Flare Placement
Traffic cones and flares can help define the incident area and provide another level of visibility. Cones and flares should be placed while facing oncoming traffic at all times.
Wear high-visibility safety apparel that meets the Performance Class 2 or 3 requirements of ANSI/ISEA 107–2004 when placing cones or flares.
Place a FIRE ACTIVITY AHEAD sign before placing cones or flares.
Use a lookout if traffic is heavy for added safety. Also take into consideration weather, sight distance, and any visual obstructions such as hills and curves.
If using flares, ignite the flares while standing on the shoulder before deploying in traffic.
