1,2,3-Trihydroxybenzene	                   87-66-1	             	 99%                  

4. FIRST AID: Eyes: Rinse immediately for 15 min. with plenty of water & transport to hospital. Skin: Rinse with plenty of soap & water and seek medical advice. Ingestion: Do not induce vomiting without medical advice. Rinse with water. Consult physician. Inhalation: Move to fresh air.  If not breathing give artificial respiration. Consult a physician. Physician: Treat symptomatically & supportively. 

5. FIREFIGHTING: Info: Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH & full PPE. Irritating & highly toxic gases may be generated by thermal decomp/combustion. Extinguishing:  Use water spray, dry chem, carbon dioxide, or alcohol-resistant foam. Haz comb:  Carbon oxides.

6. ACCIDENTAL RELEASE; Info: Use proper PPE as indicated in Section 8. Avoid contact with eyes and skin. 
Spill: Vacuum or sweep up material & place into a suitable disposal container. Clean up spills immediately, observing precautions in the Protective Equipment Section. Avoid generating dusty conditions. Provide ventilation.

7.  HANDLING & STORAGE: Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in well-ventilated area. Minimize dust generation and accumulation. Do not get in eyes, on skin, or on clothing. Do not ingest or inhale. Do not breathe dust, vapor, mist, or gas. Storage: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Do not expose to air. Absorbs oxygen from the air and will darken upon exposure. Store protected from light. 

8. EXPOSURE: 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.
