How often should breathing air be tested?
every three months
How often should you conduct breathing air tests? It is vital that the breathing air quality is maintained through regular checks and testing of the equipment and the compressed air supply. Government health and safety guidelines say that breathing air tests should be carried out at least every three months.

What is OSHA Grade D breathable air?
OSHA defines Grade D air as suitable for breathing with the following characteristics: Oxygen content of 19.5-23.5 percent. Hydrocarbon (condensed) content of 5 milligrams per cubic meter of air or less. Carbon monoxide content of 10 parts per million (ppm) or less. Carbon dioxide content of 1,000 ppm or less.

Can you use a regular air compressor for breathing air?

Which standard is applied for breathing air?
Breathing air standards were developed by ANSI and specifically the Compressed Gas Association of ANSI. These standards were then adopted by OSHA and enforced under the respiratory standard 29 CFR 1910.134. The OSHA standard draws from the Gas Association Commodity Specification for air G-7-1989.
What grade of breathing air is required for air supplied respirator?
Grade D
Most respirator manufacturers will require that Grade D or better air be supplied to their respirators. One of the most important items that most facilities are clueless about is incompatible disconnects.
What PPE should always be worn when working with compressed air?

Can you breath compressed air?
Compressed air gets used across a range of industries to provide respiratory protection. It’s used in applications where the risk of breathing ambient air is too high to mitigate using half or full-face respirators. But it is not safe to breathe the compressed air directly following compression.
