Partially full compressed gas containers containing residual gases shall be considered as full for purposes of the controls required. B. On Manufacturing 1. The compressor air intake shall be located where no contamination from engine exhausts, fuel storage vents, vacuum system discharges, particulate matter, or odor of any type is anticipated. 2. The intake to medical air compressors shall be located outdoors above roof level at a minimum distance of three meters (3 m) from any door, window, exhaust, other intake, or opening in the building, and a minimum distance of six meter (6 m) above the ground. Intakes shall be turned down and screened or otherwise be protected against the entry of vermin or water, with screening that shall be fabricated or composed of a non-corrosive material such as stainless steel or other suitable material. 3. Ventilating systems having fans with motors or drive belts located in the air stream shall not be used as a source of medical air intake. 4. Two or more compressors shall be installed as alternate for simultaneous demand. Compressors shall be sized to serve peak demand with the largest compressor out of service. 5. A device shall be provided to automatically activate the additional compressors if the unit in operation is incapable of adequately maintaining pressure. A signal indicating that the reserve compressor is running shall operate a local audio and visual alarm and serve to activate remote master alarms. 6.
