HEALTH HAZARDS DATA:
NOTE: Health studies have shown that exposure to chemicals pose potential risks which may vary from person to person. Exposure to liquids, vapors, mists or fumes should be minimized.

PRINCIPAL HEALTH HAZARDS:
Skin Contact: Prolonged/repeated exposure may cause irritation and drying or flaking of skin with possible dermatitis.
Eye Contact: May cause irritation producing tears. May cause slight temporary corneal injury.
Ingestion: May cause gastro-intestinal disturbances, pain and discomfort
Inhalation: May cause irritation and upper respiratory tract discomfort, headache, nausea, insensibility and other nervous system effects. Repeated exposure to high concentrations may cause liver and kidney damage.
Chronic Effects: Contains styrene monomer, a possible carcinogen.

FIRST AID PROCEDURES:
Skin: Avoid direct contact with this chemical, wash with soap and water, seek medical attention if a rash persists
Eyes: Flush with warm water for 20 minutes, obtain medical attention
Ingestion: DO NOT INDUCE VOMITING, have victim drink 8 to 10 oz. of water to dilute material in stomach. Seek medical attention.
Inhalation: Remove victim to fresh air if ill effects develop. If effects persist, administer oxygen, apply A/R if necessary and seek immediate medical attention.

PREVENTIVE MEASURES:
Skin: Always apply appropriate barrier cream to exposed skin. Wear impervious gloves (butyl rubber), coveralls and
safety footwear.
Eyes: Chemical proof goggles or full face respirator if vapours cause eye irritation.
Ingestion: Wash thoroughly before consuming food stuffs.
Inhalation: Use only in well ventilated areas or use NIOSH approved respiratory protection with organic vapour cartridges.

CONTROL MEASURES & PRECAUTIONS
Keep container tightly closed. Do not consume food, drink or tobacco in work area or material storage areas. Use caution and personal cleanliness to avoid skin and eye contact. Avoid breathing vapours of heated materials. Use paper covering absorbent wipes and suitable disposable containers in work area.

SPILL, LEAK & DISPOSAL METHODS
Review fire and explosion hazards and safety precautions before proceeding with cleanup. Restrict access to area. Contain spill to prevent liquid from entering sewers or waterways. Recover free liquid and use an absorbent material (i.e. sand, vermiculite) to soak up balance. Place in suitable container for disposal.

DISPOSAL METHOD
Dispose only in a facility permitted to dispose of hazardous waste by Federal, Provincial and Municipal regulations.
