breathing gas must contain less than 5 parts per million (ppm) of carbon monoxide
if the breathing gas contains higher concentrations then as it is compressed the partial pressure of carbon monoxide may rise to potentially lethal levels
main source of the gas is from the exhaust fumes of the engine of an air compressor
if not expelled well away from the inlet to the compressor, may be drawn into the diver's air cylinder
