If mold growth has occurred or materials have been wet for more than
48 hours, consult Table 2 guidelines. Even if materials are dried
within 48 hours, mold growth may have occurred. Items may be tested
by professionals if there is doubt. Note that mold growth will not
always occur after 48 hours; this is only a guideline.
These guidelines are for
damage caused by clean water. If you know or suspect that the water
source is contaminated with sewage, or chemical or biological pollutants,
then Personal Protective Equipment and containment are required
by OSHA. An experienced professional should be consulted if you
and/or your remediators do not have expertise remediating in contaminated
water situations. Do not use fans before determining that the water
is clean or sanitary.
If a particular item(s)
has high monetary or sentimental value, you may wish to consult
a restoration/water damage specialist.
§ The subfloor under the
carpet or other flooring material must also be cleaned and dried.
See the appropriate section of this table for recommended actions
depending on the composition of the subfloor. |
