Which sequence best describes the vehicle fire suppression approach?

• A. Attack from a 45-degree angle; use a piercing nozzle to access under the hood; open the door before forcing entry
• B. Attack from a 90-degree angle; use a fog nozzle; force entry first
• C. Attack from a 0-degree angle; spray from distance
• D. Attack from a 60-degree angle; rely on a halligan only

Answer: (A)

The main idea is to get control of the engine fire quickly while keeping the firefighters protected. Approaching the vehicle at about a 45-degree angle lets you work from the side, reducing exposure to radiant heat and flames while giving a stable position to reach the engine compartment. Using a piercing nozzle lets you breach into the engine bay to apply water directly to the fire, delivering fast knockdown without needing to fully open the hood and vent heat unpredictably. Opening the door before forcing entry helps verify occupant status and plan ventilation, which can reduce the need for forcible entry and improve overall safety and access. Other approaches fall short because they either don’t provide effective water application to the engine bay, rely on a method that exposes you more to heat, or skip a safe entry/ventilation sequence.
