How often are SCBA cylinders hydrostatically tested?

How often are SCBA cylinders hydrostatically tested?

• A. Every 2 years
• B. Every 5 years
• C. Every 10 years
• D. Every 7 years

Answer: (B)

Periodic hydrostatic testing checks that SCBA cylinders can safely withstand pressures beyond their normal operating level and to catch any wall flaws before they fail in use. For SCBA cylinders, the standard interval is every five years. This timing comes from NFPA 1981 guidelines and the fire service practice of scheduling a complete integrity check at five-year cycles, matching how the material and construction (steel, aluminum, or carbon-fiber wrapped) age under pressure. During the test, the cylinder is filled with water and pressurized to a higher test pressure to reveal leaks, deformation, or cracks that aren’t visible at normal service pressure. If the cylinder passes, it’s stamped with the new test date and the next due date; if it doesn’t, it’s taken out of service and handled per procedures. The other intervals listed aren’t the standard for SCBA cylinders in typical fire service practice, which is why five years is the best answer.
