What are the maximum feet allowed for supplied air lines?

The maximum length allowed for supplied air lines is 300 feet. This limitation is critical to ensure that the air supply remains safe and effective for respiratory protection during asbestos abatement activities. Longer air lines can lead to a decrease in air pressure and an increase in the possibility of contaminants entering the system, compromising the quality of the air delivered to the worker.

In general, the standards set for supplied air lines take into account factors such as pressure loss over extended distances and potential contamination risks, which is why 300 feet is considered the maximum safe distance. Ensuring that air lines do not exceed this length helps maintain the integrity of the air supply system and protects the health and safety of personnel working in environments where asbestos exposure is a concern.
