Which type of fire extinguisher is recommended for fires involving A2L refrigerants?

• A. Class A fire extinguisher
• B. Class B fire extinguisher
• C. Class C fire extinguisher
• D. Class D fire extinguisher

Answer: (B)

A Class B fire extinguisher is recommended for fires involving A2L refrigerants because these refrigerants are flammable and can ignite in the presence of an open flame or heat source. Class B fire extinguishers are designed to combat fires fueled by flammable liquids, gases, and vapors, which is applicable to A2L refrigerants. These extinguishers typically contain agents such as foam, dry chemical, or carbon dioxide, which effectively smother and suppress flammable vapors and liquids, thereby preventing the spread of the fire. Proper training and understanding of the type of fire extinguisher to use are crucial for ensuring safety in environments where A2L refrigerants are present.
