How often are SCBA cylinders hydrostatically tested?

How often are SCBA cylinders hydrostatically tested?

• A. Generally every 5 years, per NFPA guidelines, with manufacturer's instructions and local policies observed.
• B. Every 2 years.
• C. Every 10 years.
• D. Only once during the life of the cylinder.

Answer: (A)

High-pressure SCBA cylinders must be periodically checked to ensure they can safely contain the compressed air. Hydrostatic testing does this by filling the cylinder and pressurizing it to a test level higher than its normal service pressure to see if it leaks or shows any weakness or deformation. The standard interval used in the fire service is generally every five years, in line with NFPA guidelines. This timing balances safety with practicality, but the exact requirement can be influenced by the cylinder’s manufacturer and local agency policies. So the best answer is that five-year interval, with any adjustments coming from manufacturer instructions or local rules. Why the other options aren’t correct: testing every two years is more frequent than typical NFPA guidance for SCBA cylinders, testing every ten years risks missing developing flaws, and testing only once in the cylinder’s life ignores normal wear and potential damage over time.
