WAC 296-842-22020 states: Prior to each use the unit must be checked to ensure that a proper seal is achieved. A 10 second negative pressure seal check is required.
The best way to do this is with your 2nd stage regulator.

Agility– restrictive movements
Facial Features– seal issues
Contact Lenses– otherwise glasses inserts are provided
Respiratory– any smokers?
Mental– training, confidence, “cool”
Limited visibility– peripheral vision is reduced, fogging
Communication– failures of lapel mics, amplifiers not turned on.
Weight– 25-35 extra pounds
Mobility– backpack and straps reduce ability to move freely
Equipment malfunction– Know what to do if your equipment suddenly malfunctions
Cold Weather– water spray from fire fighting activities can cause SCBA to freeze up and not function properly.

Nobody wants to accept liability!
We’re talking about IMPROPERLY functioning SCBAs!
ALMOST ALL PACK FAILURES WILL OCCUR AS THE BOTTLE IS TURNED ON! Don’t let this happen at the front door!
That’s EMERGENCY OPS!
**NOTE** Vibralert will not function if this happens
If the MMR regulator won’t control it, USE THE BOTTLE VALVE! DON’T WASTE AIR!
**Remember, if the regulators do not provide air, the quick fill option will not do any good**
GET OUT FAST!! And Get Out ALIVE!!
