polyethylene sheeting and duct tape or with sealed rigid
coverings].
b.
Containment features for exterior lead hazard control projects:
[Plastic sheeting] [Portable partitions] [Colored caution tape]
[_____] [A roped-off boundary perimeter, using caution tape or a
barrier installed at [_____] distance from where the lead control
work is performed].
3.1.3
Negative Air Pressure System Containment
**************************************************************************
NOTE: Require containment to be equipped with
negative air pressure control equipment specified in
paragraph NEGATIVE AIR PRESSURE SYSTEM and operated
as specified below if lead hazard control activities
require blasting or power sanding techniques to
remove lead. Remove this paragraph if not required
in the project.
**************************************************************************
a.
The negative air pressure systems shall be operated to provide at
least [10] [_____] air changes per hour inside the containment.
The local exhaust unit equipment shall be operated continuously
until the containment is removed. The negative air pressure
system shall be smoke tested for leaks at the beginning of each
shift. The certified supervisor is responsible to continuously
monitor and keep a pressure differential log with an automatic
manometric recording instrument. The Contracting Officer shall be
notified immediately if the pressure differential falls below the
prescribed minimum. The building ventilation system shall not be
used as the local exhaust system. The local exhaust system shall
terminate out of doors unless the Contracting Officer allows an
alternate arrangement. All filters shall be new at the beginning
of the project and shall be periodically changed as necessary to
maintain specified pressure differential and shall be disposed of
as lead contaminated waste.
b.
Discontinuing Negative Air Pressure System. The negative air
pressure system shall be operated continuously during abatement
activities unless otherwise authorized by the Contracting Officer.
At the completion of the project, units shall be run until full
cleanup has been completed and final clearance testing
requirements have been met. Dismantling of the negative air
pressure systems shall [conform to written decontamination
procedures] [be approved by the Contracting Officer] [be as
presented in the Lead Hazard Control Plan]. The HEPA filter
machine intakes shall be sealed with polyethylene to prevent
environmental contamination.
