Containment Barriers and Negative Air Guide

How plastic barriers, zipper doors and negative air machines keep dust, spores and soot where they belong.

Containment is a sealed work area. Plastic sheeting, tape and zipper doors separate the work zone from clean living space. A negative air machine pulls air out of the zone through a HEPA filter, so any leakage goes in, not out.

It is used for mold, sewage, fire and demolition. A good containment looks simple but depends on tight seams, a controlled entry and steady airflow. Entry and exit procedures, such as a decontamination chamber, also keep contamination from spreading on clothing.
