Building materials and furnishings 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.
Gloves are required to protect the skin from contact with mold
allergens (and in some cases mold toxins) and from potentially
irritating cleaning solutions. Long gloves that extend to the
middle of the forearm are recommended. The glove material should
be selected based on the type of materials being handled. If you
are using a biocide (such as chlorine bleach) or a strong cleaning
solution, you should select gloves made from natural rubber, neoprene,
nitrile, polyurethane, or PVC. If you are using a mild detergent
or plain water, ordinary household rubber gloves may be used.
To protect your eyes, use properly fitted goggles or a full-face
respirator with HEPA filter. Goggles must be designed to prevent
the entry of dust and small particles. Safety glasses or goggles
with open vent holes are not acceptable.
Respirators protect cleanup workers from inhaling airborne mold,
mold spores, and dust.
Full: In situations in which high levels of airborne dust or mold
spores are likely or when intense or long-term exposures are expected
(e.g., the cleanup of large areas of contamination), a full-face,
powered air purifying respirator (PAPR) is recommended. Full-face
PAPRs use a blower to force air through a HEPA filter. The HEPA-filtered
air is supplied to a mask that covers the entire face or a hood
that covers the entire head. The positive pressure within the
hood prevents unfiltered air from entering through penetrations
or gaps. Individuals must be trained to use their respirators
before they begin remediation. The use of these respirators must
be in compliance with OSHA regulations.
