Ventilation of containment area and decontamination unit, using HEPA filters 1. Install a ventilation system in the containment area that draws the air supply through the decontamination and load-out units. 2. Operate ventilation system 24 hours a day from start of abatement through final clearance OR until Consultant directs. 3. Place at the decontamination unit entrance a pressure gauge that measures differential pressure between abatement and ambient areas. Gauge must be read hourly and logged or continuously recorded. 4. The ventilation system must create, as a minimum, a negative pressure of 0.02 inches of water inside the containment area (relative to the outside of the containment area) and must be sized for a minimum of four air changes per hour or more, as specified in the Site specific microbial abatement plan. 5. Locate HEPA filters in order to prevent dead air 6. Exhaust filtered air to outside of building, unless otherwise approved by the Industrial Hygienist.
