ASBESTOS AWARENESS
THREE OSHA REGULATIONS PERTAIN TO
PONTENTIAL WORKPLACE EXPOSURES
TO ASBESTOS
•
29 CFR 1926.1101
– Applies to construction, demolition, abatement and maintenance
activities in any structure or building. In general, most activities that
may intentionally disturb asbestos fibers are governed by this
standard.
•
29 CFR 1915.1001
– Applies to all maritime or ship related asbestos activities.
•
29 CFR 1910.1001
– Applies to all other potential occupational exposures to asbestos, that
may result in contact, which does not disturb the asbestos. Some of
these activities include:
– Housekeeping such as cleaning asbestos containing or presumed
asbestos containing building materials such as flooring or
walls
– Repairing or replacing automotive brakes and clutches
– Manufacturing of asbestos containing products.
– ASBESTOS AWARENESS TRAINING
• is a provision of the general industry standard
29 CFR 1910.1001 that requires “asbestos
awareness training” for employees who perform
housekeeping operations in an area that contains
ACM or PACM . Asbestos awareness may also
be suitable for other individuals who work
around , but do not disturb, ACM or PACM, as
well as individuals who need to be informed
about asbestos related work activities that may
be conducted by others in their work area.
ACRONYMS
• ACM
– Asbestos containing material
• PACM
– Presumed asbestos containing
material

GENERAL PROTECTIVE MEASURE
A. Identification
B. Isolation
C. Monitoring
D. Special work practices
E. Clean-up of the work area
(CAUTION: Remember, cleanup or removal of
asbestos can only be done by qualified contractors).
WARNING - CAUTION - NOTE
– Asbestos containing materials in good condition do
not pose a health hazard, nor does EPA recommend
the removal of ACM in good condition. Do not
initiate self-help, or any renovation / demolition
work that may involve building materials that are
known or suspected of containing asbestos without
coordination with Environmental.
POINTS FOR REVIEW
• 1.
What is asbestos
• Asbestos is a naturally occurring mineral that has been used
for hundreds of years as an insulation and fireproofing
material.
• 2.
Is bonded or covered asbestos a health hazard ?
• Asbestos that is bonded, coated, covered or otherwise
protected
so that no fibers can become airborne
doesn’t present a hazard.
• 3.
What is “friable” Asbestos ?
• Friable asbestos is asbestos that may be crumbled,
pulverized or reduced to powder by hand pressure when
dry. Friable asbestos has the potential to release asbestos
fibers that can become airborne.
• 4.
Can asbestos be identified visually ?
• There is no way to visually identify asbestos. Many materials that
contain asbestos look just the same as materials that don’t.
• 5.
How can you identify asbestos containing materials ?
• The only way to be sure is to have representative samples of the
material, called bulk samples, analyzed in a laboratory.
6.
What are some of the health effects that could
result from exposure to airborne asbestos fibers ?
* Asbestosis - a progressive,
non-cancerous and
irreversible scarring of the
lungs that can produce
shortness of breath..
ASBESTOSIS
PLEURAL DISEASE
* Pleural disease - plaque
deposits or a thickening of
the thin tissue that separates
the lungs from the other
organs in the body.
* Lung cancer - cancerous
tumors that have a latency
period of 20 to 30 years.
Lung cancer is usually fatal.
* Mesothelioma - a cancer in
the lining of the chest cavity
or abdomen. Mesothelioma
is always fatal.
LUNG CANCER
MESOTHELIOMA
• 7.
How does smoking relate to asbestos exposure ?
• Research has shown that smoking significantly increases the
risk of lung cancer in individuals who are exposed to
asbestos. Tobacco smoke interacts with the asbestos
increasing the damaging effects on the body’s lung tissue. A
person who smokes 2 packs a day and is exposed to asbestos
is 100 times more susceptible to lung cancer than a nonsmoker with no asbestos exposure.
• 8.
What are some of the typical locations
where asbestos may be found in the
workplace ?
•
9.
What are some of the locations within a
home where asbestos can be found ?
shingles, wall boards, tile, piping
• 10. What should you do if you suspect that asbestos
containing material may be present and that your work
activity may disturb the material ?
•
•
•
•
Stop what you are doing
Do not allow others into the area
Do not modify the suspected asbestos containing material
Do not try to clean up any debris that may include suspected
asbestos containing material
• Alert your supervisor that you may have encountered suspected
asbestos containing material. (Supervisor must immediately
contact Environmental)
• 11.
Important housekeeping procedures that relate to
asbestos containing material.
• Don’t remove any asbestos containing material unless
you have received adequate training and all
appropriate work practices are followed.
• All surfaces should be kept as free as possible of
asbestos dust, debris and waste.
• Use a High Efficiency Particulate Air (HEPA) filtered
vacuum for any clean- up of asbestos contaminated
material.
• Use wet methods to prevent dust release whenever
possible.
• Use low speed floor buffers (less than 300 RPM) with
low abrasion pads when cleaning or stripping asbestos
containing floor material. (OSHA Class 4 janitorial)
• Dispose of all asbestos contaminated materials in
properly labeled impermeable bags or containers
according to governmental requirements.
• 12. General workplace protective measures that are
employed during asbestos related work activities.
• Identification - including bulk sampling and laboratory
analysis when necessary .
• Isolation - including restricting access and erecting
enclosures when needed.
• Monitoring of the isolation, work and clean-up to verify
that the engineering controls are working properly and
that no asbestos fibers have escaped the enclosure.
(NOTE: This is done by BIO-)
• Special work practices including using proper personal
protective equipment and, where appropriate, negative
pressure within the work area to prevent fiber release.
– Protect your self from the hazards of
asbestos
• Understand the possible risk
• Follow policies and procedures and
• Do not disturb, Ask if you have any concerns.
Quicksilver Policy
• Activities that require the transporting,
removal, handling, and/or disposal of
asbestos containing material shall be
performed by qualified asbestos removal
contractors only!
