How often do wet chemical and water mist extinguishers require hydrostatic testing?

• A. Once every year
• B. Once every 5 years
• C. Once every 10 years
• D. Once every 12 years

Answer: (B)

Wet chemical and water mist extinguishers require hydrostatic testing every 5 years to ensure their structural integrity and safety. Hydrostatic testing involves applying a high pressure to the extinguisher to check for leaks, bulging, or other signs of wear or damage. This periodic testing is crucial because over time, pressure vessels can develop weaknesses that may not be visible externally, posing a risk when the extinguisher is needed for an emergency. By adhering to the 5-year testing schedule, it helps maintain compliance with safety regulations and ensures that the extinguishers will function effectively when required.
