More Definitions of Negative pressure

Negative pressure means that the direction of airflow is inward through any natural draft openings and the building is maintained to ensure negative pressure differential values of at least 0.013 mm of mercury (0.007 inches of water), as demonstrated in accordance with the relevant provisions of this Consent Decree.

Negative pressure. The gas shall not be produced at or encounter before delivery a pressure of less than atmospheric pressure.

Negative pressure means a system that extracts air directly from work area, filters such extracted air through a HEPA filtering system, and discharges this air directly outside work area to exterior of building. This system shall maintain a minimum pressure differential of 5 Pa relative to adjacent areas outside of work areas, be equipped with an alarm to warn of system breakdown, and be equipped with an instrument to continuously monitor and automatically record pressure differences;

Negative pressure means a reduced pressure within the Asbestos Work Area) (>0.04 in.) established by extracting air directly from Asbestos Work Area and discharging it to exterior of building. Volume of air extracted must be sufficient to provide one (1) air change every 20 minutes during wet removal and once every 15 minutes during dry.

Negative pressure means a pressure greater than atmospheric.

Negative pressure means a condition that exists when less air is supplied to a space than is exhausted from the space, so the air pressure within that space is less than that in surrounding areas.

Negative pressure means a reduced pressure within the Asbestos Work Area (>0.04 in.) established by extracting air directly from Asbestos Work Area and discharging it to exterior of building. Volume of air extracted must be sufficient to provide one (1) air change every 20 minutes during wet removal and once every 15 minutes during dryremoval while ensuring that at all times, air movement flows into the Asbestos Work Area as determined by visual or smoke testing to the satisfaction of the Contract Administrator..
