What is the exhaust requirement for auto repair bays?

The correct exhaust requirement for auto repair bays is based on the need to ensure safety and proper ventilation when working with potentially hazardous materials and exhaust fumes from vehicles. The guideline of 1.5 CFM (cubic feet per minute) per square foot of floor area is designed to provide sufficient air movement to dilute harmful vapors and maintain a healthy working environment for technicians.

This level of exhaust helps to reduce the accumulation of flammable and toxic substances that can build up due to the presence of solvents, fuels, and other chemicals typically used in auto repair. Proper ventilation is key in preventing adverse health effects and ensuring compliance with safety regulations, thereby securing a safe atmosphere for both workers and clients in the garage.

Option choices that exceed this requirement, such as 2.0, 2.5 CFM, or even higher amounts, may reflect a misunderstanding of the typical ventilation needs for this specific application, which should balance sufficient air exchange with energy efficiency and operational cost considerations. Hence, the established standard of 1.5 CFM per square foot is recognized as adequate for most auto repair environments.
