How often should the breathing air supplied by a compressor be tested for the presence of carbon monoxide?

How often should the breathing air supplied by a compressor be tested for the presence of carbon monoxide?

RegSense Personal Protective Equipment Safety & Health Construction Safety General Industry Safety Best Results FAQ Respiratory Protection English Focus Area USA

The frequency of monitoring will depend on the breathing air system in place, adherence to required maintenance procedures, and the location of the air intake for the compressor. For example, keeping in mind that a given measurement represents only that instant in time and must be representative of long-term air quality, periodic monitoring may be appropriate in situations where the compressor is well maintained and the air intake for the compressor is located in an area free from contaminants. In contrast, continuous monitoring would be warranted for older compressors where oil blow-by is more likely due to piston ring and cylinder wear, or in situations where rental compressors are used and/or the maintenance history is not known.
