What type of respirator pumps clean air from outside the work area?

The supplied air respirator is designed to provide clean air from an external source, ensuring that the wearer receives breathable air while working in environments where the air may be contaminated or insufficient. This type of respirator connects to an air supply, such as an air compressor or tank, allowing for an uninterrupted flow of clean air directly to the user. This is particularly important in lead abatement work, where exposure to hazardous materials can pose serious health risks.

In contrast, other types of respirators, such as powered air purifying respirators, use a filter system to clean contaminated air rather than supplying fresh air. Positive pressure respirators maintain a higher internal air pressure to prevent outside air from entering but do so by relying on an internal breathing air source rather than connecting to an external clean air supply. Half mask respirators consist of a mask that covers only part of the face but also rely on filtering air rather than supplying it from an outside source.

By utilizing a supplied air respirator, workers exposed to lead and other hazardous substances can effectively mitigate the risk associated with poor air quality, thereby enhancing their safety and health during lead abatement processes.
