Containment procedure

The first step is to use hard materials to form a frame for 4 mil to 6 mil or greater plastic to form around. Then an air tight containment is setup around the frame using negative pressure and HEPA filtration (air being sucked out of the containment and pushed outside of the building if possible). This cleans the air within and bring fresh air in to make it safe for the workers and minimize mold moving out of the area to other parts of the building. You can also see a decontamination chamber (smaller containment) for cleaning of tools, suites, masks, etc before re-entering the building by the workers.

We ensure that there are access doors to enter and exit the containment have flaps or zipper doors so that mold spore leaving the containment are minimized.


Then all the surfaces are final wet wiped and HEPA vacuumed. At this time a clearance test can be completed after a proper amount of time for HEPA air scrubbing using non-negative air filtration (closed system) to extract the majority of the mold spores in the air. It is typical that there will still be mold in the air but the typical clearance test is to show that the containment samples near the affected area are less than outside of the building samples. If there was a pre-test done it should also be shown that the air samples after remediation are lower than before remediation. Additional, a visual inspection should show no mold growth (possibly reminisce or stains but no growth) and moisture levels of the affected area should be back to normal conditions.
