What must the workplace-specific written program ensure regarding air supply?

• A. The atmosphere-supplying air is adequate
• B. It is replaced monthly
• C. It is increased monthly
• D. It is optional

Answer: (A)

The key idea is that the written program ensures the air used to supply breathing in the workplace is safe and sufficient for the task and the respirator being used. Adequate atmosphere-supplying air means it provides enough oxygen and is free from harmful contaminants or hazardous levels of gases, vapors, or particulates for the duration of the work. This involves selecting proper air sources, verifying purity (and, for breathing air, meeting applicable standards), and confirming that delivery systems supply the required flow and pressure. If the air isn’t adequate, workers could suffer oxygen deficiency or exposure to toxins, so the program requires ongoing verification and appropriate controls. Replacing air monthly, increasing air monthly, or treating air supply as optional do not address safety—adequacy is the essential requirement.
