Negative pressure enclosure definition
Negative pressure enclosure means an air-tight enclosure using a local exhaust and HEPA filtration system to maintain a lower air pressure in the work area than in any adjacent area and to generate a constant flow of air from the adjacent areas into the work area.
Negative pressure enclosure means any enclosure of an asbestos abatement project where the air pressure outside the enclosure is greater than the air pressure inside the enclosure and the air inside the enclosure is changed at least four times an hour by exhausting it through a HEPA filter.
Negative pressure enclosure means a barrier surrounding the area of asbestos abatement comprised of a plastic with a minimum thickness of 6 mil any enclosure of an asbestos abatement project area where the air pressure outside the enclosure is greater than the air pressure inside the enclosure and the air inside the enclosure is changed at least four times an hour by exhausting it exhausting through a HEPA filter exhaust system measured by an attached and functioning manometer or similar device and resulting in a negative pressure environment of -0.02 inches of water column. The barrier must cover all gaps in the area surrounding the asbestos abatement including but not limited to doorways, windows, HVAC systems, drains, plumbing, and other gaps.
