Description / Abstract:
This practice describes work practices for asbestoscement
products when maintenance, renovation, and repair are required.
This includes common tasks such as drilling and cutting holes in
roofing, siding, pipes, etc. that can result in exposure to
asbestos fibers if not done carefully. These work practices are
supplemented and facilitated by the regulatory, contractual,
training, and supervisory provisions of this practice.
Materials covered include those installed in or on buildings and
facilities and those used in external infrastructure such as water,
wastewater, and electrical distribution systems. Also included is
pavement made from asbestos-cement manufacturing waste.
The work practices described herein are intended for use only
with asbestos-cement products already installed in buildings,
facilities, and external infrastructure. They are not intended for
use in construction or renovation involving the installation of new
asbestos-cement products.
The work practices are primarily intended to be used in
situations where small amounts of asbestos-cement products must be
removed or disturbed in order to perform maintenance, renovation,
or repair necessary for operation of the building, facility, or
infrastructure.
The work practices described herein are also applicable for use
where the primary objective is the removal of asbestoscement
products from the building or other location, particularly the use
of wet methods and other means of dust and fiber control.
The values stated in inch-pound units are to be regarded as
standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and
are not considered standard.
Warning—Asbestos fibers are acknowledged
carcinogens. Breathing asbestos fibers can result in disease of the
lungs including asbestosis, lung cancer, and mesothelioma.
Precautions in this practice should be taken to avoid creating and
breathing airborne asbestos particles from materials known or
suspected to contain asbestos. Comply with all applicable
regulatory requirements addressing asbestos.
This practice does not address safety hazards associated
with working on asbestos-cement products such as falling through
roof panels or trench cave-ins. The use of power tools presents
possible electrical hazards, particularly in wet environments.
These and other safety hazards must be considered and controlled in
compliance with the employer's policies and applicable
regulations.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
