What is the minimum mechanical ventilation rate required per square foot of floor area over a storage area?

The minimum mechanical ventilation rate required per square foot of floor area over a storage area is set at 1 cfm. This standard ensures that sufficient fresh air is supplied to the space, which is crucial for maintaining air quality and preventing the buildup of harmful contaminants, especially in storage environments where materials may off-gas or require specific ventilation to remain safe.

In storage areas, proper ventilation helps to control temperature and humidity levels, as well as to reduce the risk of mold and mildew, which can thrive in poorly ventilated conditions. Achieving this minimum ventilation rate also facilitates compliance with health and safety regulations, ensuring that the environment is suitable for both stored items and personnel who may enter the space.

By adhering to the established rate of 1 cfm, HVAC professionals can effectively contribute to the overall efficiency and safety of the system that services these storage areas.
