How FD Blockers Prevent Accidents and Improve Work-Zone Safety

FD blockers put a rated barrier between traffic and the responders working an incident scene. They extend attenuator protection beyond planned work zones.

Incident scenes are some of the most dangerous places on a highway. Responders work in the open, often at night, with traffic still moving past. FD blockers give them the same kind of protection a TMA gives a work crew: a rated barrier that absorbs an errant vehicle instead of the people behind it.

What a blocker protects against

• Distracted or impaired drivers approaching a scene at speed.
• Secondary crashes, where traffic reacting to the first incident causes another.
• The exposure of firefighters, medics, and police working in live lanes.

Part of a larger setup

A blocker does its best work alongside clear signaling. Arrow boards and message boards warn drivers early; the blocker stands as the last line if a warning is missed. Positioned upstream of the scene, it absorbs the hit and keeps the errant vehicle out of the work area, buying responders the space they need.
