Never give anything by mouth to an unconscious person. Get medical aid immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Vapors can travel to a source of ignition and flash back.
During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use water spray to keep fire-exposed containers cool. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. Vapors may form an explosive mixture with air.
