| SECTION 3 - HAZARDS IDENTIFICATION |
|-------------------------------------------------------------------------|
EMERGENCY OVERVIEW: WARNING! Injurious to eyes. May cause burns. May cause
eye and skin irritation. Avoid skin and eye contact. Removal of this
product after use will result in the generation of dust. If dry-sanded,
exposure to dust may result in build-up of material in eyes, ears, nose,
and mouth which may cause irritation.
POTENTIAL HEALTH EFFECTS: The International Agency for Research on Cancer
(IARC)has determined that crystalline silica in the form of quartz or
cristobalite that is inhaled from occupational sources is carcinogenic to
humans (Group 1没 carcinogenic to humans). Refer to IARC Monograph 68,
Silica, Some Silicates and Organic Fibres (published in June 1997) in
conjunction with the use of these materials. The National Toxicology
Program (NTP) classifies respirable crystalline silica as 么known to be a
human carcinogen枚. Refer to the 9th Report on Carcinogens (2000). The
American Conference of Governmental Industrial Hygienists (ACGIH)
classifies crystalline silica, quartz, as a suspected human carcinogen
(A2).
EFFECTS OF OVEREXPOSURE - EYE CONTACT: May cause eye irritation.
EFFECTS OF OVEREXPOSURE - SKIN CONTACT: May dry skin. May develop
enough heat to cause burns if a large mass such as a cast of hand or arm,
is kept in contact with skin while hardening.
EFFECTS OF OVEREXPOSURE - INHALATION: Exposure to dust may cause
irritation to nose, throat, and respiratory system.
EFFECTS OF OVEREXPOSURE - INGESTION: Ingestion may result in
obstruction when wetted plaster hardens.
EFFECTS OF OVEREXPOSURE - CHRONIC HAZARDS: Breathing dust containing
respirable crystalline silica may not cause noticeable injury or illness
even though permanent lung damage may be occurring. Inhalation of dust may
have the following serious chronic health effects: Excessive inhalation of
respirable dust can cause pneumoconiosis, a respiratory disease, which can
result in delayed, progressive, disabling and sometimes fatal lung injury.
Symptoms include cough, shortness of breath, wheezing, non-specific chest
illness and reduced pulmonary function. Smoking exacerbates this disease.
Individuals with pneumoconiosis are predisposed to develop tuberculosis.
There is some evidence that breathing respirable crystalline silica or the
disease silicosis is associated with an increased incidence of significant
disease endpoints such as scleroderma (an immune system disorder manifested
by fibrosis of the lungs, skin and other internal organs) and kidney
disease.

| SECTION 7 - HANDLING AND STORAGE |
|-------------------------------------------------------------------------|
STORAGE INFORMATION: Store away from caustics and oxidizers. Keep
containers tightly closed when not in use. Keep containers from excessive
heat and freezing. Do not store at temperatures above 120 degrees F.
OTHER PRECAUTIONS: Use in a well ventilated area. Provide fresh air such
that chemical odors cannot be detected during use and while drying.
|-------------------------------------------------------------------------|
| SECTION 8 - EXPOSURE CONTROLS/PERSONAL PROTECTION |
|-------------------------------------------------------------------------|
ENGINEERING CONTROLS: If dry-sanding, provide sufficient mechanical
ventilation to maintain exposure below PEL and TLV. While mixing, provide
sufficient mechanical ventilation (local or general exhaust) to maintain
exposure below PEL and TLV.
RESPIRATORY PROTECTION: National Institute for Occupational Safety and
Health (NIOSH) has recommended that the permissible exposure limit be
changed to 50 micrograms respirable free silica per cubic meter of air
(0.05 mg/m3) as determined by a full shift sample up to 10 hour working
day, 40 hours per week. The 1974 NIOSH Criteria for a recommended Standard
for Occupational Exposure to Crystalline Silica should Be consulted for
more detailed information. If 8 hour exposure limit or value is exceeded
for any component, use an approved NIOSH/OSHA dust mask. Consult your
safety equipment supplier and the OSHA regulation, 29 CFR 1910.134 for
respirator requirements. A respiratory protection program that meets OSHA
1910.134 and ANSI Z88.2 requirements must be followed whenever workplace
conditions warrant a respirator's use. If 8 hour exposure limit or value is
exceeded for any component, use an approved NIOSH/OSHA respirator. Consult
your safety equipment supplier and the OSHA regulation, 29 CFR 1910.134 for
respirator requirements. A respiratory protection program that meets OSHA
1910.134 and ANSI Z88.2 requirements must be followed whenever workplace
conditions warrant a respirator's use.
EYE PROTECTION: Safety glasses with side shields recommended.
SKIN PROTECTION: Gloves recommended for repeated or prolonged contact with
skin.
OTHER PROTECTIVE EQUIPMENT: Provide eyewash and coveralls if body contact
may occur.
HYGIENIC PRACTICES: Remove contaminated clothing and wash before reuse.

The International Agency for Research on Cancer (IARC) published monograph
in 1997 (Volume 68, Silica, Some Silicates, Coal Dust and Para-Aramid
Fibrils) changing its classification of crystalline silica from a Group 2A
category (probably carcinogenic to humans) to a Group 1 category
(carcinogenic to Humans) by concluding that 么 there is sufficient evidence
in humans for the carcinogenicity of inhaled crystalline silica脿 from
occupational sources.枚
In April 2000, the American Conference of Government Industrial Hygienists
(ACGIH) classified crystalline silica as a 么Suspected Human Carcinogen枚 and
reduced its recommended Threshold Limit Value for exposure to crystalline
silica to .05 mg/m3 (respirable fraction) over an 8 hour tome weighted
average.
In May 2000, the National Toxicology Program (NTP) changed its
classification of respirable crystalline silica from 么reasonably
anticipation to be a carcinogen枚 to 么known to be a human carcinogen枚.
The 2001 ACGIH Threshold Limit Values for Chemical Substances and Physical
Agents lists the median Respirable Particulate Mass (RPM) point for
crystalline silica at 4.0 microns in terms of the particle's aerodynamic
diameter.
