Which of the following statements is true concerning the Halon 1301 fire extinguishing agent?

Correct Answer: Option B — Halon extinguishes the fire by a chain breaking reaction.

Halon 1301 is a clean agent that suppresses fires by chemically interrupting the combustion chain reaction. Unlike water or CO2, it is highly effective at low concentrations and does not leave a residue, making it particularly suitable for protecting sensitive electrical equipment and machinery spaces.
