Approaching and Ending Fire Activity Zones
Application Notes
Incident management activities may occur throughout an incident zone over a long section of road.
Use the FIRE ACTIVITY AHEAD sign with a distance plaque indicating the length of the traffic control zone as the first sign in a series of incident management signs.
Use the END FIRE ACTIVITY sign to let road users know that they may resume normal driving. Place the END FIRE ACTIVITY sign on the opposite side of the road from the FIRE ACTIVITY AHEAD sign warning road users coming from the other direction.
If the incident activity occurs over more than 5 miles of road, install additional FIRE ACTIVITY AHEAD signs with the distance plaque at least every 5 miles.

For operations lasting less than 30 minutes, signs are not required if the incident vehicle uses activated high-intensity rotating, flashing, oscillating, or strobe lights.
Hazard-warning signals on vehicles may be used to supplement—but not replace—high-intensity rotating, flashing, oscillating, or strobe lights.
