You come upon a crashed vehicle displaying a hazardous materials placard, with emergency responders on scene. What should you do?
-
A.
Move your vehicle closer to see if you can help identify the placard
-
B.
Evacuate as best you can by following the directions of emergency responders Correct
-
C.
Approach the vehicle to help pull the driver out
-
D.
Stand at the edge of the scene to direct traffic around the crash
The answer is "Evacuate as best you can by following the directions of emergency responders"
For a crash involving a hazardous materials placard, evacuate as best you can by following responder directions. Choice C appeals to the instinct to pull an injured driver out; the placard warns that the load itself can harm anyone approaching, and delayed toxic exposure is why responders control the perimeter.
The traps in the wrong answers
A. Move your vehicle closer to see if you can help identify the placard
Moving closer exposes you to the hazard rather than evacuating you from it. This answer treats placard identification as a bystander task, when responders already have it in hand.
C. Approach the vehicle to help pull the driver out
The placard warns of a hazardous load that can harm anyone approaching the vehicle. This answer overrides the placard warning with a good-Samaritan reflex to reach the driver.
D. Stand at the edge of the scene to direct traffic around the crash
Directing traffic is not among the steps the manual describes for a placarded crash. This answer substitutes a bystander-helper role the manual never assigns for a hazardous-load scene.
