[Fire Fighting] Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. In case of fire use water spray, dry chemical, carbon dioxide, orchemical foam. | |
[Fire Potential] HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. | |
[Ingestion] Get medical aid immediately. Wash mouth out with water. | |
[Inhalation] Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. | |
[Skin] Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. | |
[Eyes] Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids. Get medical aid. | |
[Storage] Keep away from sources of ignition. Store in a cool, dry place. Store in a tightly closed container. | |
[Handling] All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood. | |
[Ingestion] Harmful if swallowed. | |
[Inhalation] May cause irritation. | |
[Skin] May cause irritation. | |
[Eyes] May cause irritation. | |
[Hazards] Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. | |
