How to use a Self-Contained Breathing Apparatus - Breathe Safety

[@piecetoyou8285]

Got to say this was very clear instructions to follow, and very helpful Thank you I just bought a SABRE air fed breathing apparatus for paint spraying that has this same lung demand valve connected to the mask with a hose and a air compressor fitment nothing else , the person i bought it of said he used it when spraying a few cars and no longer needs it, I own an air compressor, that goes up to 200 psi and the cylinder holds about 100ltr As I am aware of the oil and water vaper from a compressor that may mix with my air it will be connected to a few water and oil filtration traps first, I was wondering if there were a device that would connect to an air compressor hose line and tell me if there is an odour from the oil coming through the air line. Any advice on my rig up that i might not have thought of would be noted and put in place,
