Air fills from fire station SCBA compressors

[redacted]

Unfortunately the THC in this context (as I understand it) is mostly methane.

Cows or beer?

 

[NAM001]

thc ,,,,,,,,,,,,, total hydrocarbon

many older fire stations that do not have scuba teams had compressors that only put out grade d. I thought that I saw somewhere the air quality of SCBA was now L or E or something like it. some one I am sure can find the regs for required scba air quality.
