Cylinder hydro date for SCBA cylinders should be performed how often?

Cylinder hydro date for SCBA cylinders should be performed how often?

• A. Every 2 years
• B. Every 3 years
• C. Every 5 years
• D. Every 10 years

Answer: (C)

Cylinder hydro date for SCBA cylinders should be performed every five years. This hydrostatic test checks the cylinder’s strength by applying pressure higher than its normal operating pressure and inspecting for leaks, cracks, or deformation. Standards for SCBA use (NFPA 1981 and related DOT requirements) specify a five-year interval for this test, ensuring the cylinder remains safe to use under its service pressure. The date stamped on the cylinder marks when the next test is due, so after a successful hydro test, a new hydro date is recorded and the five-year cycle starts again. The other intervals aren’t the typical requirement for standard SCBA cylinders.
