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:
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 OVEREXPOSURE - CHRONIC HAZARDS: Inhalation of dust may result in
pulmonary and respiratory damages. Prolonged or repeated inhalation of dust may cause
lung damage. Respirable crystalline silica dust is considered a suspect human carcinogen by
IARC. Risk to ones health depends on level and duration of exposure.
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.

SECTION 5 - FIRE FIGHTING MEASURES
=========================================================
FLASH POINT: N.A. LOWER EXPLOSIVE LIMIT: N.A.
UPPER EXPLOSIVE LIMIT: N.A.
AUTOIGNITION TEMPERATURE: N.E.
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 (MSHA/NIOSH approved or equivalent) and full protective gear.
Use water spray to cool exposed surfaces.
=========================================================
SECTION 6 - ACCIDENTAL RELEASE MEASURES
=========================================================
SPILL OR LEAK PROCEDURES: Sweep up excess powder. Place remaining powder into
containers.
=========================================================
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: 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.
