Negative Pressure Containment
Negative pressure containment is a key technique in professional mold work. Plastic barriers isolate the work area, and filtered air is exhausted out of it, so air flows into the containment rather than escaping into the rest of the building.
The problem
What usually leads to a call about negative pressure containment
Removing moldy material disturbs spores and dust. Without containment, they spread through doorways, stairwells, and ductwork. Negative pressure turns the work area into a controlled space and protects the clean parts of the property.
Signs to watch for
- Any remediation involving removal of drywall, insulation, or flooring
- Work in occupied homes or buildings
- Mold near HVAC returns
- Sensitive occupants elsewhere in the building
Scope
