Precleaning
Wet wipe and HEPA vacuum all surfaces potentially contaminated with
asbestos prior to establishment of an enclosure.
3.2.4
Asbestos Control Area Requirements
**************************************************************************
NOTE: When negative pressure enclosure is
infeasible, use paragraph entitled "Glovebag" and
delete paragraph entitled "Negative Pressure
Enclosure." If the project has both areas which can
be enclosed and areas which cannot be enclosed,
retain the appropriate paragraphs and identify the
areas which must be enclosed and the areas which
cannot be enclosed.
**************************************************************************
3.2.4.1
Negative Pressure Enclosure
Block and seal openings in areas where the release of airborne asbestos
fibers can be expected. Establish an asbestos negative pressure enclosure
with the use of curtains, portable partitions, or other enclosures in order
to prevent the escape of asbestos fibers from the contaminated asbestos
work area. Negative pressure enclosure development shall include
protective covering of uncontaminated walls, and ceilings with a continuous
membrane of two layers of minimum 0.15 mm 6-mil plastic sheet sealed with
tape to prevent water or other damage. Provide two layers of 0.15 mm 6-mil
plastic sheet over floors and extend a minimum of 300 mm 12 inches up
walls. Seal all joints with tape. Provide local exhaust system in the
asbestos control area. Openings will be allowed in enclosures of asbestos
control areas for personnel and equipment entry and exit, the supply and
exhaust of air for the local exhaust system and the removal of properly
containerized asbestos containing materials. Replace local exhaust system
filters as required to maintain the efficiency of the system.

NOTE: Specify the asbestos material to be removed
in the first blank and identify the location of the
area which cannot be enclosed in the second blank.

The construction of a negative pressure enclosure is infeasible for the
[removal] [encapsulation] of [_____] located [_____]. Use alternate
techniques as indicated in 29 CFR 1926.1101. Establish designated limits
for the asbestos regulated area with the use of rope or other continuous
barriers, and maintain all other requirements for asbestos control areas.
The PQP shall conduct personal samples of each worker engaged in asbestos
handling (removal, disposal, transport and other associated work)
throughout the duration of the project. If the quantity of airborne
asbestos fibers monitored at the breathing zone of the workers at any time
exceeds background or 0.01 fibers per cubic centimeter whichever is
greater, stop work, evacuate personnel in adjacent areas or provide
personnel with approved protective equipment at the discretion of the
Contracting Officer. This sampling may be duplicated by the Government at
