| (a) Restrictions. An O&M licensee is limited to
performing the practices and procedures described in this section
for O&M activities in a public building that involve friable and
nonfriable ACBM and are SSSD activities. These activities are subject
to the following conditions:
(1) the practices and procedures must be performed
by individuals licensed or registered to perform the applicable activity
and supervised by a licensed O&M supervisor or a licensed asbestos
abatement supervisor;
(2) an asbestos O&M licensee may perform or supervise,
as applicable, an SSSD O&M activity following the practices and
procedures described in this section;
(3) if the practices and procedures are supervised
by an O&M supervisor, the public building must be under the control
of the O&M supervisor's employer who is a licensed asbestos O&M
contractor or a licensed asbestos abatement contractor;
(4) a larger project must not be broken down into smaller
projects or tasks in order to qualify under this section as an SSSD
O&M project to circumvent the restricted applicability of this
section or other applicable requirements of this chapter;
(5) an activity conducted under, or a licensee or public
building owner acting under, this section remains subject to all applicable
requirements of §296.191 of this chapter (relating to Asbestos
Management in a Public Building, Commercial Building, or Facility),
including, without limitation, the requirement of an asbestos survey
performed by an individual licensed to conduct it and the requirement
to provide DSHS with written notification, as required in §296.251
of this chapter (relating to Notifications) and §296.211 of this
chapter (relating to General Requirements for Asbestos Abatement in
a Public Building); and
(6) the practices and procedures described in this
section do not limit and must be used only to the extent that they
are consistent with the requirements of any other applicable law,
including 29 CFR §1926.1101 (relating to Asbestos).
(b) Work practices. Work practices under this section
must comply with the following requirements.
(1) An employer must furnish and require the use of
a respirator, protective clothing, HEPA vacuum machines, glove bags,
and other necessary equipment for an employee who performs an SSSD
O&M activity.
(2) A regulated area must be established where an SSSD
O&M activity will be conducted and at minimum, asbestos caution
tape must be used to demarcate the regulated area. Except as otherwise
provided by other applicable law, access to the regulated area must
be limited to:
(A) licensees;
(B) emergency responders;
(C) licensed, registered, or accredited building professionals
required for emergency situations;
(D) appropriate governmental inspectors;
(E) authorized personnel, in accordance with 29 CFR §1926.1101(e)
(relating to Asbestos); and
(F) a building owner or building owner's authorized
representative, if authorized by the O&M contractor and accompanied
by a licensed O&M contractor, licensed asbestos abatement contractor,
licensed O&M supervisor, licensed asbestos abatement supervisor,
licensed asbestos consultant, or the consultant's designated licensed
asbestos project manager or licensed asbestos air monitoring technician
project monitor. A building owner or building owner's authorized representative
who enters the regulated area must have at a minimum the personal
protective equipment required for workers performing the SSSD O&M
activity and must comply with all other applicable health and safety
procedures.
(3) A warning sign that complies with 29 CFR §1926.1101,
must be displayed at all entrances to regulated area. To protect the
public from accidental entry, a warning sign must be displayed, at
minimum, in both Spanish and English at the same location. Asbestos
caution tape must not be substituted for a warning sign.
(4) Before beginning the SSSD O&M activity, all
uncontaminated movable objects must be removed from the regulated
area or covered with 4-mil thick plastic sheeting. Any object that
is already contaminated must:
(A) be cleaned with a HEPA-filtered vacuum or wet-wiped
before removal; or
(B) be completely encased in two layers of 6-mil thick
plastic sheeting and treated as ACWM.
(5) Asbestos material must be wetted with amended water
or another wetting agent and remain wet throughout the work operation
and until final disposal, unless wet methods are not feasible because
the asbestos work is being performed on live electrical equipment
or in other areas where water will seriously damage materials or equipment.
(6) A small amount of ACM may be removed by using a
glove bag, removing the entire asbestos-covered pipe or structure,
or constructing a mini-containment, as appropriate, in accordance
with the following procedures for the method utilized.
(A) Glove bags.
(i) A glove bag made of transparent 6-mil thick plastic,
and seamless at the bottom, must be installed so that it completely
covers the pipe or other structure where asbestos work is to be done.
The open edges must be folded together and securely sealed with tape.
All openings in the glove bag must be sealed with duct tape or equivalent
material and the integrity of the bag must be maintained at all times.
(ii) Respirator use and selection must comply with
29 CFR §1910.134 (relating to Respiratory protection) and it's
required written respiratory protection program, in accordance with
29 CFR §1926.1101(h)(2), 29 CFR §1910.1001(g)(2) (relating
to Asbestos), and 40 CFR Part 763, Subpart G (relating to Asbestos
Worker Protection), whichever is applicable. An employee who performs
asbestos removal with a glove bag or in close contact with the glove
bag must properly wear required respirators at all times during SSSD
O&M activity.
(iii) The ACM must be thoroughly wetted with amended
water before it is removed from the pipe (applied with a sprayer through
the precut port provided in most glove bags or applied through a small
hole in the bag). A razor knife must be used to cut any painted canvas
covering ACM and peel it away from the ACM. Nips, tin snips, or other
appropriate tool must be used to cut and remove any wire mesh covering
the ACM. If the ACM beneath the canvas or wire mesh is dry, it must
be resprayed with a wetting agent, including any layer of dry material
that is exposed beneath the mesh, the surface of the stripped underlying
structure, and the inside of the glove bag.
(iv) Once the ACM is removed from the pipe it must
be thoroughly wetted with amended water.
(v) After removal of the layer of ACM, the surface
from which asbestos was removed must be thoroughly cleaned with a
wire brush and wet-wiped with a wetting agent until no traces of the
ACM are visible.
(vi) An asbestos-containing insulation edge that was
exposed as a result of the removal or maintenance activity must be
encapsulated with a bridging encapsulant that creates a membrane over
the surface before the glove bag is removed.
(vii) When the asbestos removal and encapsulation is
complete, the glove bag must be vacuumed with a HEPA-filtered vacuum
by inserting the vacuum's hose into the glove bag through the port.
Once the air has been removed from the bag, the bag, after being squeezed
tightly as close to the top as possible and twisted, must be sealed
with tape. Once the HEPA vacuum is then removed from the bag, the
glove bag itself must be removed from the work area for proper disposal.
A glove bag must only be used once and must not be moved.
(B) Mini-containments.
(i) A mini-containment must completely contain any
disturbance or removal of ACM and must be constructed of 6-mil thick
plastic sheeting by:
(I) affixing the plastic sheeting to the walls with
spray adhesive and tape;
(II) covering the floor with plastic, and sealing that
plastic floor covering to the plastic on the walls; and
(III) sealing any penetration, such as pipes or electrical
conduit, with tape; or
(IV) using equivalent methods that effectively establish
a leak-proof and puncture-resistant mini-containment; and
(V) constructing a change room, contiguous to the mini-containment,
made of 6-mil thick plastic sheeting, supported by 2-inch by 4-inch
lumber, or equivalent, to which the plastic is attached with staples
or spray adhesive and tape, or which otherwise complies with 29 CFR §1926.1101(j)
and 40 CFR Part 763, Subpart G, whichever is applicable.
(ii) Before use, the mini-containment must be checked
for leaks and any leaks sealed.
(iii) The mini-containment must be placed under negative
pressure by means of a HEPA-filtered vacuum or similar ventilation
unit.
