When discharging a Halon fire extinguisher in the cabin, why is it mandatory for the cabin crew member to wear a Protective Breathing Equipment (PBE)?

Halon gas is toxic when inhaled and decomposes into highly irritating halocarbon byproducts under extreme heat. Halon completely depletes the cabin of all oxygen within 5 seconds of discharge. The PBE protects the crew member from the freezing temperature of the liquid water agent. PBE is only worn to block the loud noise of the extinguisher discharging.

Correct Answer:

Halon gas is toxic when inhaled and decomposes into highly irritating halocarbon byproducts under extreme heat.
