CHAPTER 6-600. ASBESTOS PROJECTS
§6-607. Standards for Minor, Small and Incidental Asbestos Projects. [48]
A. The Board shall establish by regulation standards for minor and
small asbestos projects in order to protect the health and safety of occupants
of private residences and buildings and the general public by preventing the
dispersal of asbestos fibers through the building, private residences, or into
the environment. Such minor and small asbestos project standards shall include,
but shall not be limited to, the following requirements:
(1) Work
Area Preparation:
(a) Appropriate caution signs shall be posted at
all entrances to the asbestos project work area and the waste storage area at
all times during the asbestos project until the re-occupancy standard has been
met.
(b) All furniture, equipment, fixtures, and other movable objects
shall be HEPA-vacuumed and, where feasible, wet-cleaned and removed from the
work area.
(c) All other objects that cannot be removed shall be
HEPA-vacuumed and, where feasible, wet-cleaned and covered with plastic sheeting
taped in place.
(d) Except for small asbestos projects, the work area
shall be isolated for the duration of the asbestos project by completely
enclosing the work area and sealing off all doors, windows, ducts, and other
openings with plastic sheeting taped in place.
(e) Except for small
asbestos projects, all floors, walls, and other surfaces, shall be covered with
plastic sheeting, as specified by the major project standards, taped in
place.
(f) A sealable barrier of plastic sheeting shall be constructed
at the entrance to the work area.
(g) All ventilation systems into and
out of the work area shall be shut down.
(h) Occupants shall be removed
from any floor where an asbestos project is in progress unless the work area is
completely enclosed and sealed off from other areas.
(2) Asbestos
Project Procedures:
(a) General Procedures:
(.1) No
person shall enter the work area without proper equipment, clothing, and
training.
(.2) The contractor or supervisor shall provide all
authorized persons who enter the work area with the same protective clothing and
equipment required for major asbestos projects and shall ensure that it is
properly used.
(.3) The contractor or supervisor shall ensure that all
workers remove asbestos debris from clothing and equipment before leaving the
work area.
(.4) The contractor or supervisor shall ensure that
appropriate air monitoring to determine worker exposure shall be conducted for
asbestos workers not covered by the OSHA Asbestos Standard.
(b) Other
Procedures:
(.1) The contractor or supervisor shall ensure that all
removal, enclosure, encapsulation, waste disposal, work area clean-up, and
re-insulation procedures required for major asbestos projects are
followed.
(c) Air Monitoring:
(.1) Air monitoring shall be
conducted both inside and outside the work area in accordance with the methods
and procedures established by the Board.
(.2) Air sampling and
analysis shall be conducted according to the latest NIOSH or EPA method for
phase contrast or electron microscopy, if a standard NIOSH or EPA protocol has
been established.
(.3) Air samples shall be analyzed by an independent
certified laboratory by appropriate analytic methods.
(.4) The
asbestos contractor or supervisor shall immediately halt asbestos work and
implement appropriate remedial measures if air testing results show any increase
in airborne asbestos levels outside the work area which exceeds the standard set
for major asbestos projects.
(.5) The Board shall establish a
re-occupancy standard setting a maximum airborne asbestos level no higher than
one one-hundredth (.01) fibers per cubic centimeter of air or the ambient level
outside the building, whichever is greater.
(.6) After final clean-up,
the asbestos project work area, including any part of the building evacuated
during an asbestos project, shall not be unsealed or re-occupied until air
testing results show that airborne asbestos levels do not exceed the
re-occupancy standard.
(d) The asbestos project work area, including
any part of the building evacuated during an asbestos project, shall not be
unsealed or re-occupied until the contractor or supervisor certifies
that:
(.1) based on a visual inspection, the area contains no visible
dust or debris; and,
(.2) based on the results of aggressive air
monitoring, the airborne asbestos level in the area does not exceed the
re-occupancy standard.
(e) Alternate Standards:
(.1) The
Board may establish by regulation alternate standards for renovation, repair,
and demolition projects involving non-friable asbestos materials that may be
rendered friable by project activity, and for projects involving the repair or
enclosure of friable asbestos materials where the asbestos materials are not
disturbed by the process of repair or enclosure.
B. The Board shall
establish by regulation standards for incidental asbestos projects in order to
protect the health and safety of occupants of buildings and private residences
and the general public by preventing the dispersal of asbestos fibers through
the building, private residence or into the environment.
