How often shall the air quality from compressors, cascade storage cylinders, and related equipment be tested?

• A. at least every 3 months
• B. daily
• C. every 6 months
• D. yearly

Answer: (A)

Regular testing of breathing air from compressors and cascade storage is essential to keep SCBA air safe for firefighters. The standard requires a quarterly check, meaning at least every three months. This cadence catches issues like oil carryover, moisture, particulates, and trace contaminants before they reach the cylinders. Daily or continuous checks aren’t the typical requirement for this system, and waiting six months or a year could let problems go undetected and compromise air quality. If a test shows contaminants outside allowable limits, maintenance actions such as refreshing filters, drying systems, or servicing equipment must be performed before use. Adhering to a quarterly testing schedule helps ensure consistent safety while remaining practical to implement.
