Question 265Safety & Environmental - 1st Asst/Chief

The correct answer is B. The key factors are that the engine room has been flooded with CO2 to extinguish a fire, and the emergency team needs to re-enter the space safely. Option B is correct because it specifies that the team should wait until there are no signs of smoke or heat before approaching the engine room door. This ensures that the CO2 has done its job and the space is safe to re-enter. The team should then approach the door with firefighting gear and SCBA (self-contained breathing apparatus) and crack the door open with a charged fire hose at the ready, in case any fire remains. The other options are incorrect because they either specify an arbitrary wait time (A and D) or do not mention the use of a charged fire hose (C), which is an important safety precaution when re-entering a space that has been flooded with CO2.
