Which Halon extinguishing agents have been identified as ozone depleting agents?

• A. 1301, 1211, and 2402
• B. 1302, 1212, and 2403
• C. 1300, 1200, and 2401
• D. 1301, 1210, and 2400

Answer: (A)

Ozone depletion potential (ODP) of Halon extinguishing agents is what this question hinges on. The Halons that have been identified as ozone-depleting substances are those containing bromine, which releases reactive bromine radicals that harm the stratospheric ozone layer when discharged. Among common Halons, the ones listed as ozone-depleting are 1301, 1211, and 2402. These are the classic ozone-depleting Halons that have been phased out under international agreements. The other Halon formulations mentioned differ in composition and are not identified as ozone-depleting agents in this context, so they’re not the correct trio here.
