Current through Register Vol. 56, No. 18, September 16, 2024
(a) To
allow the lead dust to settle, post abatement cleaning shall begin no sooner
than one hour after the lead hazard abatement project has been
completed.
(b) Cleaning shall take
place when the abatement project has been completed and before abated surfaces
are painted or sealed.
1. Removal of plastic
sheeting shall be done as follows:
i. Plastic
sheeting used in the abatement area shall be removed first. Plastic sheeting
used to isolate the abatement area shall be removed only when all other plastic
sheeting has been removed;
ii.
Immediately prior to removal, plastic sheeting shall be misted with water to
hold down dust. If necessary, to prevent debris from falling on unprotected
floors, moistened debris on plastic sheeting covering floors shall be swept
toward the middle of the plastic sheeting prior to folding;
iii. Plastic sheeting shall be removed by
folding the ends toward the middle to trap any dust residue;
iv. The plastic sheeting shall be placed in
double four mil or single six mil plastic bag(s) that are then sealed with duct
tape and removed from the project area for disposal; and
v. The plastic sheeting shall be removed in
the following order:
(1) Upper level plastic
sheeting, such as that on cabinets and counters;
(2) The top layer of the floor plastic
sheeting;
(3) Vent cover and
doorway plastic sheeting;
(4)
Bottom layer of floor plastic sheeting; and
(5) Plastic used to isolate the abatement
project.
2.
Work clothing and equipment shall be decontaminated as follows:
i. Work clothing shall be placed in a bag.
The bag shall be labeled and sealed for transport to a laundry facility
equipped to clean lead contaminated clothing or shall be discarded with other
project waste;
ii. All tools shall
be wiped down with rags or sponges using trisodium phosphate or other detergent
solution formulated to bind lead. An original, marked container showing the
nature of the formula and any necessary precautions shall be available at the
work site. The name of the product used and its manufacturer shall be included
in the records retained by the contractor;
iii. Disposable supplies such as mop heads,
sponges, and rags shall be sealed and shall be disposed of as allowed by the
New Jersey Department of Environmental Protection; and
iv. Durable equipment such as power and hand
tools, generators, and vehicles shall be HEPA vacuumed and then washed with a
detergent solution as required in (b)2ii above prior to removal from the work
site.
3. The abatement
area(s) shall be vacuumed with a HEPA vacuum cleaner as follows:
i. HEPA vacuuming shall be sequenced to avoid
passing through rooms already cleaned. The entryway shall be vacuumed last;
and
ii. In each room, vacuuming
shall begin with the ceiling and shall proceed down the walls. Every surface
shall be vacuumed including, but not limited to, ceiling, walls, windows,
window sills, exterior sills, window wells, doors, heating and air conditioning
equipment, fixtures, such as light fixtures, and built-in appliances. Floors
shall be the final surface vacuumed.
4. The abatement area(s) shall be wet washed
with a detergent solution as required in (b)2ii above prepared in accordance
with manufacturer's instructions.
i. In each
room, the wet wash process shall begin with the ceiling and work down to the
floor following the sequence in (b)3i and ii above.
ii. String mops and mop buckets with wringers
are required for wet washing floors. Sponge mops shall not be used.
5. When dry, the abated area(s)
shall be HEPA vacuumed again, following the sequence in (b)3i and ii
above.
6. As an alternative to the
HEPA vacuum, wet wash, HEPA vacuum cycle described in (b)3 above, a HEPA spray
cleaner vacuum may be used.
(c) A preliminary visual inspection shall be
conducted to ensure that all surfaces described in the scope of work have been
abated and that there is no visible lead dust or residue.
1. If the visual inspection is
unsatisfactory, the HEPA vacuum, wet wash, HEPA vacuum cycle described in (b)3
through 5 above shall be repeated.
2. If the visual inspection is satisfactory,
any other construction work that will disturb lead-based paint surfaces shall
be completed.
(d) All
abated surfaces, such as walls, ceilings, and woodwork, shall be primed with an
appropriate primer. Those areas shall then be painted or stained and sealed.
Surfaces subjected to repeated friction, such as window sashes, jambs, sills,
and wells, shall be painted with a final coat of high gloss enamel or clear
sealer.
1. Surfaces enclosed with vinyl,
aluminum coil stock, or other materials that are traditionally not painted, and
new replacement components are exempt from this provision.
(e) After the painting or sealing has been
completed, a final cleaning of the area is required unless dust clearance tests
were already passed prior to painting or sealing. The final cleaning shall
follow the HEPA vacuum, wet wash, HEPA vacuum cycle described at (b)3 through 5
above.
1. Surfaces newly painted with latex
paint are exempt from the final wet wash. However, those surfaces must be HEPA
vacuumed.
