Emergency Exit and Evacuation

What this domain tests

Emergency Exit and Evacuation tests exit locations, the decision to evacuate or stay aboard, how far to move students, and how to supervise the group once they are out.

Core rules

  • Exits include the main door, the rear emergency door, emergency side windows, roof hatches, and on some buses a left-side door.
  • Evacuate for fire or the smell of smoke, an unsafe stopping position, or any situation you cannot control.
  • Stay aboard with a downed power line unless the bus is on fire; the bus body protects riders.
  • Move students at least 100 feet from the bus and off the roadway. Go upwind of a hazardous-material release.
  • Set the parking brake, shut off the engine, turn on the hazard lights, and radio for help.
  • Take the extinguisher, first aid kit, and reflectors when you can do so safely, and assign an older student to help at the rear door.
  • Stand outside where you can see every student, usually near a front or rear corner away from traffic.

Worked example

Smoke pours from the engine compartment of a conventional bus. Because the engine sits at the front, the driver sends students out the rear emergency door, walks them upwind to a point 100 feet off the road, and radios dispatch while counting heads against the route list.

Traps that cost marks

  • Evacuating students into the traffic lane instead of away from the road.
  • Leaving the bus in gear or without the parking brake set.
  • Using the front door when the fire is at the front of the bus.
  • Failing to account for every student after they leave the bus.
