When attacking a fire in the passenger area of a vehicle, you should pay special attention to which safety factor?

• A. The Fire Stream to Maintain a Tight Pattern.
• B. Fires in the Engine or Trunk First.
• C. Using a Prying Tool to Break the Windows.
• D. Supplemental Restraints.

Answer: (D)

Supplemental restraints, such as airbags and seat belt pretensioners, are the safety factor to watch in the passenger area. Airbags are located in the dash, steering wheel, and sometimes side panels, and their inflators can be heated or damaged by fire. Heat or embers can cause an airbag to deploy violently or rupture an inflator, sending gas and debris into the cabin and injuring anyone nearby. Seat belt pretensioners, which tighten the belt during a crash, rely on pyrotechnic charges that can fire in high heat or electrical faults, creating unexpected torque and crowding the space you’re working in. Because these systems live in the passenger compartment, crews must approach with awareness that they could deploy unexpectedly or become a dangerous obstacle during rescue and fire-fighting operations. This is why paying special attention to supplemental restraints is the safest priority in this scenario. Other considerations like stream pattern, addressing engine fires first, or breaking windows are important tactics, but the immediate risk inside the passenger area comes from these restraint systems.
