|-------------------------------------------------------------------------|
EMERGENCY OVERVIEW: WARNING! Injurious to eyes. When mixed with water, this
material hardens and then slowly becomes hot. DO NOT attempt to make a
cast enclosing any part of the body using this material. Failure to follow
these instructions may cause severe burns that may require surgical removal
of affected tissues. 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.
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: : Irritating to mouth, throat, and
stomach. Ingestion may result in obstruction when wetted plaster hardens.
EFFECTS OF OVER EXPOSURE - CHRONIC HAZARDS
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 known to be a human carcinogen. 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).
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.
MEDICAL CONDITIONS WHICH MAY BE AGGRAVATED BY CONTACT: Asthma and
asthma-like conditions may worsen from prolonged and repeated exposure.
PRIMARY ROUTE(S) OF ENTRY: SKIN CONTACT INHALATION
|-------------------------------------------------------------------------|
| SECTION 4 - FIRST AID MEASURES |
|-------------------------------------------------------------------------|
EYE CONTACT: Flush with large quantities of water until irritation
subsides. Contact a physician.
SKIN CONTACT: Wash with soap and water. If irritation persists consult a
physician.
INHALATION: Remove to fresh air. Contact a physician immediately.
INGESTION: DO NOT INDUCE VOMITING. Contact a physician or Regional Poison
Control Center immediately.
COMMENTS: In case of a medical emergency call: 1-800-327-3847.

EXTINGUISHING MEDIA: CO2 DRY CHEMICAL FOAM
UNUSUAL FIRE AND EXPLOSION HAZARDS: None known. Material will not burn.
SPECIAL FIREFIGHTING PROCEDURES: As in any fire, wear self-contained
breathing apparatus pressure-demand (NIOSH approved or equivalent) and
full protective gear. Use water spray to cool exposed surfaces.
|-------------------------------------------------------------------------|
| SECTION 6 - ACCIDENTAL RELEASE MEASURES |
|-------------------------------------------------------------------------|

| SECTION 7 - HANDLING AND STORAGE |
|-------------------------------------------------------------------------|
HANDLING INFORMATION: KEEP OUT OF REACH OF CHILDREN. Avoid prolonged or
repeated contact with skin. Avoid contact with eyes. Do not inhale dusts
of this product.
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. Prevent build up of
dust by providing fresh air such that dust cannot be detected during use
and while any sanding.
|-------------------------------------------------------------------------|
| 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.
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.
