CDE Emergency Procedures & First Aid Flashcards

What is the primary purpose of placing flares or reflective triangles around a crash scene?

Answer: To warn approaching drivers and prevent secondary collisions

Warning devices alert oncoming traffic so that additional crashes do not occur at an already hazardous scene.

A driver's brakes suddenly fail while driving downhill. What is the best immediate action?

Answer: Downshift to a lower gear and look for a runaway-truck ramp or soft terrain

Downshifting uses engine braking to slow the vehicle, and runaway-truck ramps or soft shoulders provide a safe deceleration area.

What should a driver do if the accelerator pedal becomes stuck?

Answer: Shift to neutral, apply steady brake pressure, and pull safely off the road

Shifting to neutral cuts engine power while maintaining steering and braking control until you can safely stop.

At a crash scene with multiple casualties, which victim should bystanders prioritize for first aid?

Answer: Those who are silent and not breathing or have severe bleeding

Silent victims who are not breathing or have uncontrolled bleeding face the greatest immediate threat to life and require priority attention.

What is the recommended rate for chest compressions when performing hands-only CPR?

Answer: 100–120 compressions per minute

The American Heart Association recommends 100–120 compressions per minute to effectively circulate blood during cardiac arrest.

If a vehicle catches fire after a crash, when should occupants attempt to exit?

Answer: Immediately, before the fire spreads to the fuel tank

A vehicle fire can spread rapidly to the fuel system, causing an explosion, so immediate evacuation is essential.
