Question 216Safety & Environmental - QMED
70% to passWhy is it essential to introduce CO2 from a fixed fire extinguishing system, into a large engine room, as quickly as possible?
AThe fire may warp the CO2 piping.
BTo keep the fire from spreading through the bulkheads.
CCarbon dioxide takes a long time to disperse to all portions of a space.
DUpdraft from the fire tends to carry the CO2 away.
AI Explanation
The correct answer is D) Updraft from the fire tends to carry the CO2 away. The reasoning behind this is that a fire in an engine room creates a strong updraft, which can carry the carbon dioxide (CO2) away from the seat of the fire before it has a chance to extinguish the flames. Introducing the CO2 quickly is essential to ensure it reaches the base of the fire and smothers the flames before the updraft disperses it. The other answer choices are incorrect because: A) the fire itself does not warp the CO2 piping, B) the goal is to extinguish the fire, not just prevent it from spreading, and C) while CO2 can take time to disperse, the key issue is the updraft, not the dispersion time.
