Question 233Safety & Environmental - QMED

The correct answer is D) Halon 1301 extinguishes the fire by a chain breaking reaction. Halon 1301 is an effective fire extinguishing agent that works by interrupting the chemical chain reaction of the fire. It does this by releasing bromine atoms that disrupt the combustion process, effectively extinguishing the fire. This chain breaking mechanism makes Halon 1301 highly effective, especially on electrical fires, as it does not leave any conductive residue. The other answer choices are incorrect. Halon 1301 is more effective than carbon dioxide, it is not highly toxic when stored in pressurized cylinders, and it can be used on electrical fires without leaving a residue.
