Explanation:
At one time, Halon was considered the perfect fire suppression method in computer operations centers, due to the fact that it is not harmful to the equipment, mixes thoroughly with the air, and spreads extremely fast. The benefits of using Halons are that they do not leave liquid or solid residues when discharged.
Therefore, they are preferred for sensitive areas, such as computer rooms and data storage areas.
However, several issues arose with its deployment, such as that it cannot be breathed safely in concentrations greater than 10 percent, and when deployed on fires with temperatures greater than 900°, it degrades into seriously toxic chemicals - hydrogen fluoride, hydrogen bromide, and bromine.
Some common EPA-acceptable Halon replacements are
FM-200 (HFC-227ea)

CEA-410 or CEA-308

NAF-S-III (HCFC Blend A)

FE-13 (HFC-23)

Argon (IG55) or Argonite (IG01)

Inergen (IG541)

Low pressure water mists

Incorrect Answers:
B: Inergen is an EPA-approved replacement for Halon. Therefore, this answer is incorrect.
C: FM-200 is an EPA-approved replacement for Halon. Therefore, this answer is incorrect.
D: FE-13 is an EPA-approved replacement for Halon. Therefore, this answer is incorrect.
