The purchase of Halon fire extinguishers for flight line, hanger, and shop use is?

• A. Required
• B. Prohibited
• C. Restricted
• D. Permitted

Answer: (B)

Halon extinguishers are tightly controlled because those chemicals deplete the ozone layer. Global and national regulations limit who can buy Halon and for what uses, making new purchases for flight line, hangar, or shop use not allowed. In practice, you should avoid buying new Halon extinguishers and instead use approved substitutes or work only with existing, properly managed Halon stock through licensed service providers. This is why the correct stance is that purchasing Halon extinguishers for those environments is prohibited.
