Where should negative pressure machines be located relative to the decontamination unit?

The correct choice is to position negative pressure machines in the area furthest away from the decontamination unit. This placement is crucial for maintaining safety and ensuring that any potential contaminants are effectively contained within the work area. By locating the negative pressure machines away from the decontamination unit, you minimize the risk of spreading asbestos fibers or other hazardous materials to areas designated for clean personnel and equipment.

Negative pressure machines work by creating suction that draws air (and any airborne contaminants) towards them, effectively preventing contaminants from escaping into the surrounding environment. When they are positioned at a distance, it allows for a more controlled flow of air, ensuring that any particulate matter remains away from clean zones and the exit points for workers. This setup enhances the overall effectiveness of the asbestos abatement process and protects the health of workers and the integrity of surrounding areas.
