During post-use SCBA maintenance, which action is performed just after reassembling the unit?

• A. Clean the exterior only.
• B. Reassemble the unit.
• C. Check and recharge the cylinder.
• D. Log maintenance.

Answer: (C)

The main idea here is ensuring the air supply is ready and safe before the unit is stored or returned to service. After reassembling the SCBA, the next step is to verify the cylinder’s charge and bring it up to the proper pressure if needed. This checks that you actually have sufficient breathing air and that the system holds pressure without leaks, which is essential for the unit to be usable when needed. If you only cleaned the exterior or logged the maintenance without confirming the cylinder is charged, you could end up with a unit that looks fine but has no air or a low-pressure condition. Logging typically comes after all checks are complete, and cleaning exterior is a separate, often earlier or later, housekeeping step.
