General Requirements
Prepare Area
Non-stationary items should be removed from the work area to prevent contamination of
the items and to facilitate the removal process.
Cover Fixed Objects
Items not being removed from the work area, such as light fixtures etc., should be wetwiped or HEPA vacuumed and wrapped in place with 6-mil polyethylene and sealed with
duct tape.
Electrical outlets should be sealed with tape or covered with 6-mil polyethylene and then
taped and the electricity shut off at the breaker panel. All electricity should be brought
into the abatement area through a ground fault interrupter (GFI).
Critical Barriers
Critical barriers shall be installed in order to reduce the chance of airborne asbestos fibers
and/or lead dust being released into the environment outside this containment. All vents,
air ducts and other openings inside the work area should be covered and sealed with twolayers of 6-mil polyethylene and duct tape. The first layer of polyethylene should be left
in place until the area has passed final visual inspection and clearance air and/or wipe
sampling.
Wall Cover
One layer of 6-mil polyethylene is used to cover the walls including windows. The sheets
should be hung from the top of the wall. The vertical sheets should be overlapped and
seam-sealed with spray adhesive and duct tape.

Floor Cover
Six mil polyethylene sheets should be used to cover the floor (scaffold). Sheets may be
seamed together with spray adhesive and duct tape with a minimum 12-inch overlap at
the seams.
3.0
Decontamination Unit
The decontamination unit (Decon) is designed to allow passage to and from the wok area
during the removal operations. A typical unit consists of a clean room, a shower room
and an equipment room separated by airlocks.
Clean room
No asbestos and/or lead-contaminated items should enter this room. Workers use this
area to suit up, store street clothes, and don respiratory protection prior to entering the
work area.
Shower room
All persons are required to pass through the shower room after exiting the work area. The
Contractor’s supervisor will be responsible to ensure all personnel and equipment is
decontaminated prior to entering the clean room.
Equipment room
This is a contaminated area where equipment, boots or shoes, hard-hats, goggles, and any
additional contaminated stored work clothes. Workers shall place disposable clothing
such as coveralls and hoods in bins/bags before leaving this area for the shower room.
Respirators are worn until workers enter the shower and thoroughly wash them with
water. The equipment room may require cleanup several times daily to prevent asbestos
and or lead containing materials from being tracked into the shower and clean room.
Water used during this process will be filtered through a 20-micron followed by a 5micron water filter prior to being discharged in the public water system.
4.0
Engineering Control
Engineering controls will include the use of high efficiency particulate air-filtered
(HEPA) vacuums, ventilation and negative air filtration systems. The use of negative air
filtration system includes:
1
Changing the air within the containment area approximately once every 15
minutes.
2
Establishing condition in which air from all portions of the containment area is
being pulled toward the negative air filtration system.
The exhaust units should be located so that the makeup air enters the work area primarily

through the decontamination facility and traverses the work area as much as possible.
Provide HEPA filters that are individually tested and certified by the manufacturer and
able to trap 99.97% of all particles 0.3 microns in diameter & larger. The exhaust units
should be started prior to removal and should run continuously to maintain a constant
negative pressure until decontamination of the work area is complete.
Replace the pre-filters two to four times a day or when accumulations of particulate
matter become visible. Intermediate filters must be replaced once every day, and the
HEPA filter may be replaced prior to removal, if needed.
5.0
Asbestos Work Procedures
Environmental Protection Agency (EPA) regulations which cover the removal of asbestos
materials (40 CFR, part 61, subparts A&B) require wetting of ACMs before removal
begins and keeping the material wet while removal is in progress and until it is bagged
for disposal.

dust being released into the environment outside this containment:
•
•
•
•
•
Misted water
Local HEPA filtered exhaust, i.e. vacuum
Area ventilation
Critical barriers
Other methods deemed appropriate for the job
Prior to each work shift and continuously throughout the project, containment area shall
be inspected and repaired as needed.
If the Contractor’s work practices cause a release of lead paint chips or dust from the
work area as determined by the Consultant, then additional engineering controls must be
implemented. The construction of additional containments shall be at no additional cost
to the Owner.

Final Visual Inspection and Air Monitoring
Once the gross portion of the asbestos and lead-containing materials are removed, the
work area shall be detail cleaned. The contractor’s competent person will notify the
consultant for a visual inspection.
Once the consultant is satisfied that the area is clean the contractor’s competent person
will mist the entire work area with a “lock-down” encapsulant and determine the setting
time for the encapsulating compound.
Air Monitoring
Area air samples for asbestos and lead will be collected on a daily basis during the
abatement phase.
Asbestos
Should any exterior area air sample exceed the EPA clearance criteria of 0.01 fibers per
cubic centimeter of air (f/cc), analysis by Phase Contrast Microscopy (PCM), during the
asbestos removal, the work will be stopped and Omega Environmental Services, Inc.
(Omega) on-site inspector will determine what action shall be taken to reduce the
airborne fiber concentration to / or below 0.01f/cc.
Post asbestos abatement air sampling will be conducted using high volume pumps with
the flow rate between 8 to 16 liters per minute, and the sample volume shall be no less
than 1200 liters. All collected air samples for asbestos will be analyzed using NIOSH
Method 7400, “A” counting rules.
Lead
Ambient airborne lead levels outside the work area, cannot exceed the action level of 30
micrograms per cubic meter (30µg/m³) or baseline, whichever is less. If the airborne lead
concentration outside the work area should exceed 30µg/m³, then abatement must stop
and operations be reviewed and modified until the airborne lead concentration can be
reduced to within the acceptable limits.
8.0
Respiratory Protection
The abatement Contractor is responsible for providing respirators, and all employees
assigned to work in the containments are required to wear a minimum half-face respirator
equipped with High Efficiency Particulate Air (HEPA) filters, which must be approved
by the National Institute for Occupational Safety and Health (NIOSH).

All waste materials shall be disposed of in double 6-mil impermeable bags at a minimum.
The waste materials shall be kept in a wet state until the bags are completely sealed and
labeled. Do not overfill the bags; remember wet material is much heavier than dry. Care
must be taken when placing heavy or sharp objects into the plastic disposable bags to
prevent accidental spills.
After the waste is sealed in the properly labeled bags/containers, the waste may be
removed from the containment area. Prior to transporting the bags they should be wet
wiped, HEPA vacuumed, or rinsed off to prevent the transfer of any asbestos fibers or
lead dust to the outside environment.
All waste should be placed (not thrown) into the containers for transport to the landfill.
