Cartridge or cylinder operated dry chemical extinguishers with mild steel shells require hydrostatic testing how often?

• A. Once every year
• B. Once every 5 years
• C. Once every 12 years
• D. Once every 15 years

Answer: (C)

Cartridge or cylinder operated dry chemical extinguishers with mild steel shells require hydrostatic testing once every 12 years. This testing is crucial for ensuring the integrity and safety of the extinguisher under pressure. Over time, materials can degrade, and internal pressure can affect the structural soundness of the cylinder. The 12-year interval is established by standards set by organizations such as the National Fire Protection Association (NFPA) and is designed to keep extinguishers operational and safe for users. By adhering to this schedule, you help to ensure that the extinguisher can perform effectively in an emergency situation.
