What are the requirements for a breathing air compressor?
It must be constructed and situated so as to: • Prevent entry of contaminated air into the air-supply system. • Minimize moisture content so that the dew point at 1 atmosphere pressure is 10 degrees F (5.56 C) below the ambient temperature. • Have suitable in-line air-purifying sorbent beds and filters to further ensure breathing air quality. Sorbent beds and filters shall be maintained and replaced or refurbished periodically following the manufacturer’s instructions. • Have a tag containing the most recent change date and the signature of the person authorized by the employer to perform the change. The tag shall be maintained at the compressor.
