A
Effective even if ventilation is not shut down
B
Non-corrosive
C
Effective on electrical equipment
D
Will not deteriorate in storage
AI Explanation
The correct answer is A) Effective even if ventilation is not shut down. Carbon dioxide (CO2) fire-extinguishing agents are not effective if ventilation is not shut down. CO2 works by displacing the oxygen in the air, which suffocates the fire. If ventilation is not shut down, the CO2 will be quickly dispersed, rendering the agent ineffective. The other characteristics listed - non-corrosive, effective on electrical equipment, and not deteriorating in storage - are accurate for CO2 fire extinguishers.
