Functional Tests

WARNING! 

•

Wear eye protection while performing functional tests.

•

If the SCBA does not operate correctly for all functional tests, remove the SCBA from service. Make sure an MSA trained and certified repair technician corrects the unsatisfactory condition before returning the SCBA to service.

Failure to follow these warnings can result in serious personal injury or death.

NOTE: The cylinder must be full during functional tests. Before starting the functional tests, look at the pressure gauge on the cylinder valve assembly to make sure the cylinder is full.

If the SCBA passes all visual inspections successfully, do the functional tests.

If any part of the SCBA fails the functional test, remove the SCBA from service and return it to a certified repair technician.
