What is the service interval for a wet chemical fire extinguisher?

• A. Every 12 months
• B. Every 3 months
• C. Every 6 months
• D. Every 24 months

Answer: (C)

Regular service of wet chemical extinguishers is about keeping the pressure system, seals, and the chemical agent in proper working order. In kitchen environments, where these extinguishers are common, heat, humidity, and oil residues can accelerate wear or allow leaks and contamination to develop. Check-ups every six months provide a reliable balance: they catch issues like pressure loss, blocked or degraded discharge paths, or degraded agent before an emergency, while not being so frequent as to be unnecessary for typical use. Waiting longer than six months increases the risk that a fault goes unnoticed and the extinguisher fails when needed. Shorter intervals, like every three months, are usually not required unless the specific facility or local code calls for it, and longer intervals such as annually or every two years risk unrevealed problems.
