What does the 'service life' label on an SCBA cylinder indicate?

• A. It indicates hydrostatic test dates and overall service life; cylinders exceeding limits must be removed from service.
• B. It indicates the color coding of the cylinder.
• C. It indicates the manufacturing factory.
• D. It indicates the recommended cleaning schedule.

Answer: (D)

The service life label on an SCBA cylinder shows how long the cylinder is considered safe to use and when it must be re-tested or retired. It typically encodes both the overall life expectancy of the cylinder and the date by which the next hydrostatic test is required. This label helps ensure the cylinder is not used past its safe period, since cylinders exceeding their service life or due for testing must be removed from service. This isn’t about color coding, the factory where it was made, or a cleaning schedule. Those aspects are unrelated to the cylinder’s safety life, which centers on aging and testing requirements.
