Method 4 — Discard Remove damaged materials and seal in plastic bags. Building materials and fur- nishings that are contaminated with mold growth and are not salvageable should be double-bagged using 6-mil polyethylene sheeting. These materials can then usually be discarded as ordinary construction waste. It is important to package mold- contaminated materials in sealed bags before removal from the containment area to minimize the dispersion of mold spores throughout the building. Large items that have heavy mold growth should be covered with polyethylene sheeting and sealed with duct tape before they are removed from the containment area. Always use gloves and eye protection when cleaning up mold. Containment The purpose of containment during remediation activities is to limit release of mold into the air and surroundings, in or- der to minimize the exposure of remedia- tors and building occupants to mold. Mold and moldy debris should not be allowed to spread to areas in the building beyond the contaminated site. In general, the size of the area helps determine the level of containment. How- ever, a heavy growth of mold in a relatively small area could release more spores than a lighter growth of mold in a relatively large area. Choice of containment should be based on professional judgment. The primary object of containment should be to prevent occupant and remediator exposure to mold. Limited Containment: Limited contain- ment is generally recommended for areas involving between 10 and 100 sq. ft. of mold contamination. The enclosure around the moldy area should consist of a single layer of 6-mil, fi re-retardant polyethylene sheeting. The containment should have a slit entry and covering fl ap on the outside of the containment area. For small areas, the polyethylene sheeting can be affi xed to fl oors and ceil- ings with duct tape. For larger areas, a steel or wooden stud frame can be erected and polyethylene sheeting attached to it. All supply and air vents, doors, chases, and risers within the containment area must be sealed with polyethylene sheeting to minimize the migration of contaminants to other parts of the building. Heavy mold growth on ceiling tiles may impact HVAC systems if the space above the ceiling is used as a return air plenum. In this case, containment should be installed from the fl oor to the ceiling deck, and the fi lters in WE'VE BEEN FOLLOWING THE BUILDING BLOCKS OF RESPONSIBLE DESIGN & MANUFACTURING SINCE 1962.
