SECTION 2 - COMPOSITION, INFORMATION ON INGREDIENTS
Risk Phrases: 22 36/38 45 52/53
SECTION 3 - HAZARDS IDENTIFICATION EMERGENCY OVERVIEW Harmful if swallowed. Irritating to eyes and skin. May cause cancer. Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment. Potential Health Effects
Causes eye irritation.
Causes skin irritation. May be absorbed through the skin in harmful amounts. If absorbed, causes symptoms similar to those of ingestion.
Harmful if swallowed. May cause liver damage. Contact with stomach acid may liberate toxic hydrogen sulfide gas. Hydrogen sulfide affects the nervous system producing headache, dizziness, excitement, staggering gait, diarrhea, and painful or difficult urination. H2S doesn't combine with hemoglobin; its asphyxiant action is due to paralysis of the respiratory center.
May cause respiratory tract irritation. May cause effects similar to those described for ingestion.
Possible cancer hazard based on tests with laboratory animals. Chronic ingestion may cause liver damage. When administered in the diet, thioacetamide induced hepatocellular carcinomas in mice of both sexes, hepatocellular neoplasms in male rats, and bile duct or cholangiocellular neoplasms in rats of both sexes.
SECTION 4 - FIRST AID MEASURES
In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid.
In case of contact, flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical aid if irritation develops and persists. Wash clothing before reuse.
If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Get medical aid.
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
SECTION 5 - FIRE FIGHTING MEASURES
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. Runoff from fire control or dilution water may cause pollution.
Use extinguishing media most appropriate for the surrounding fire.
SECTION 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, observing precautions in the Protective Equipment section. Avoid generating dusty conditions. Provide ventilation. U.S. regulations require reporting spills and releases to soil, water and air in excess of reportable quantities.
SECTION 7 - HANDLING and STORAGE
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Avoid breathing dust.
Store in a cool, dry place. Keep containers tightly closed.
SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations low. Exposure Limits CAS# 62-55-5: Personal Protective Equipment
Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Wear appropriate protective gloves to prevent skin exposure.
Wear appropriate protective clothing to prevent skin exposure.
A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant respirator use.
