How many hours per day must alternative air for Medical Air compressor intakes be available?

The requirement for alternative air sources for medical air compressor intakes is set to ensure continuous availability of medical air in healthcare facilities. According to NFPA 99, the standard specifies that alternative air must be available for a minimum of 24 hours per day. This requirement is crucial for patient safety and respiratory health, as medical air is necessary for powering ventilators and other life-supporting equipment.

Having an alternative air source available 24 hours a day ensures that in the event of a failure of the primary medical air system, the facility can continue to provide safe and effective respiratory care without interruption. The specification is part of a broader risk management strategy within healthcare environments, emphasizing the stability and reliability of medical gas systems.
