Level I: Small Isolated Areas (10 sq.
ft or less) - e.g., ceiling tiles, small areas on walls.
- Remediation can be conducted by the
regular building maintenance staff as long as they are
trained on proper clean-up methods, personal protection,
and potential health hazards. This training can be
performed as part of a program to comply with the
requirements of the OSHA Hazard Communication Standard (29
CFR 1910.1200).
- Respiratory protection (e.g., N-95
disposable respirator) is recommended. Respirators must
be used in accordance with the OSHA respiratory
protection standard (29 CFR 1910.134). Gloves and eye
protection should be worn.
- The work area should be unoccupied.
Removing people from spaces adjacent to the work area is
not necessary, but is recommended for infants (less than
12 months old), persons recovering from recent surgery,
immune-suppressed people, or people with chronic
inflammatory lung diseases (e.g., asthma,
hypersensitivity pneumonitis, and severe allergies).
- Containment of the work area is not
necessary. Dust suppression methods, such as misting (not
soaking) surfaces prior to remediation, are recommended.
- Contaminated materials that cannot be
cleaned should be removed from the building in a sealed
impermeable plastic bag. These materials may be disposed
of as ordinary waste.
- The work area and areas used by
remediation workers for egress should be cleaned with a
damp cloth or mop and a detergent solution.
- All areas should be left dry and
visibly free from contamination and debris.
