Mechanical exhaust for central supply locations should not exceed how many cubic feet per minute (cfm)?

The appropriate limit for mechanical exhaust in central supply locations is set to not exceed 500 cubic feet per minute (cfm). This standard is in place to ensure the safe removal of any potentially hazardous gases or contaminants that could be present in medical gas storage and supply areas. Maintaining the exhaust within this limit helps to balance the need for effective ventilation with energy efficiency and noise control considerations.

Exceeding this limit might lead to safety issues, including the potential for gas accumulation if the exhaust system is not properly designed or managed. Furthermore, regulations and guidelines, such as those from the National Fire Protection Association (NFPA) and the Facility Guidelines Institute (FGI), emphasize the importance of adhering to these established limits for health and safety in medical environments.

As a result, the selection of 500 cfm reflects industry standards aimed at ensuring adequate ventilation and maintaining a safe environment in facilities that supply medical gases.
