What is the minimum airflow requirement in a repair garage when the facility is occupied?

The minimum airflow requirement in a repair garage when the facility is occupied is set to ensure adequate ventilation, maintaining air quality and safety standards for workers and customers. The established standard of 1 cfm (cubic foot per minute) per square foot of occupied space is deemed sufficient to adequately dilute and remove potential contaminants, such as exhaust fumes, solvents, and dust generated from the repair work.

Ensuring that a repair garage meets this minimum airflow requirement not only helps comply with health and safety regulations but also contributes to a more comfortable working environment. It is critical in settings where there may be a build-up of hazardous substances or where workers are exposed to various chemicals and materials.

Higher airflow rates can lead to improved air quality but may not be necessary for every situation and can result in increased energy costs. Hence, the standard of 1 cfm/ft² strikes a balance between safety and economic efficiency in common repair garage environments.
