Question

Which statements are true of halon as a fire suppression agent? (Choose TWO):

A) Halon is safe for humans.
B) Halon deals with Class A category of fire.
C) Halon gas suppresses fire by a chemical reaction.
D) FM-200 is an EPA-approved replacement for halon.
E) Halon is currently approved by the Environmental Protection Agency (EPA).

Answer 1

The true statements are that halon suppresses fire by a chemical reaction, and FM-200 is an EPA-approved replacement for halon. Halon is not currently EPA-approved due to its environmental impact.

Step-by-step explanation:

The true statements about halon as a fire suppression agent are that halon gas suppresses fire by a chemical reaction (C) and that FM-200 is an EPA-approved replacement for halon (D). Halon is indeed able to stop fires through a chemical reaction that interrupts the combustion process. However, due to environmental concerns, particularly its role in depleting the ozone layer, usage of halon as a fire suppressant has been largely phased out and is not currently approved by the EPA. The FM-200 system is one of the replacements that has been developed which impact the environment less significantly.
