According to the EPA, why is it recommended to clean up mold?
It gradually destroys the things it grows on.
How should materials that cannot be salvaged be disposed of?
Double bagged using 6 mil poly. Bags must be sealed before disposal to minimize mold dispersion. Large items with heavy mold should be covered with poly sheeting and sealed with duct tape.
Is there special disposal instructions once bagged?
No, mold can be disposed of like regular garbage.
What size surface area is limited containment?
10 to 100 sq feet
What size surface area is full containment used?
More than 100sf
What is a PAPR and when is it recommended?
Power air purifying respirator used in full containment situations. It uses a blower to force air through the HEPA filter that is supplied to a mask that covers the entire face.
The containment must be maintained by what type of pressure?
Negative
Double layers of 6 mil poly should be used in what type of containment?
Full – surface area greater than 100 square feet
What type of containment is recommended in the EPA guidance for 10 to 100sf?
Minimum
- one layer of fire retardant 6mil poly
- hvac return/supply blocked
- slit opening and flap on the outside of containment
- objects being removed must be cleaned/remediated prior to removal
- the containment is to be ventilated with HEPA ventilation unit exhausted outside the building
What containment is recommended for removal of mold by the EPA for greater than 100sf?
Full
- double layers of fire retardant 6 mil poly
- a decon chamber or airlock constructed for entry into and exit from remediation area (airlock chamber)
- slit entry with flap
- should be large enough to hold waste container and allow person to put on/remove PPE, all contaminated PPE should be placed in sealed bag in this chamber, excluding respirators
- respirators should be worn until outside decon chamber.
PPEs must be worn when during full containment?
Must be worn throughout the final stages of HEPA vacuuming and damp wiping of the contained area. PPE must also be worn during HEPA vacuum filter changes or cleanup of the HEPA vacuum
