Ohio Volunteer Firefighter Practice Exam

Question: 1 / 400

How long is an electric vehicle considered unsafe after it has been turned off?

5-10 minutes

10-15 minutes

An electric vehicle remains unsafe for about 10-15 minutes after it has been turned off due to the potential hazards associated with the high-voltage systems that can persist after the vehicle is powered down. During this time, the capacitors within the vehicle's electrical system may still hold a charge, posing a risk of electric shock to anyone working on or around the vehicle. Firefighters and first responders must wait for this critical period to ensure that these systems are properly discharged, minimizing the risk of injury.

This timeframe is important for safety protocol in emergency situations, as it allows for the assessment of any potential hazards and ensures that responders do not encounter unforeseen dangers while dealing with electric vehicles. The option that indicates a duration longer than this range may not reflect the best current practices for safety when handling such a vehicle.
