Which statement correctly describes the SCBA cylinder maintenance interval?

Which statement correctly describes the SCBA cylinder maintenance interval?

• A. Tested every 2 years
• B. Tested every 5 years
• C. Tested every 10 years
• D. Never tested

Answer: (B)

SCBA cylinders must be proven to withstand the pressures they’ll face, and that proof comes from a hydrostatic test conducted at five-year intervals. This test pushes the cylinder to a higher pressure than normal service pressure and looks for any cracks, delamination, or other signs of weakness. Keeping this interval ensures cylinders remain safe to use and helps identify when a cylinder should be retired or replaced. So the correct maintenance interval is five years.
