If breathing is difficult, give oxygen. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask. Treat symptomatically and supportively. No specific antidote exists. Vapors may form an explosive mixture with air.
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. Wear appropriate protective clothing to prevent contact with skin and eyes. Reacts with most metals to form highly flammable hydrogen gas which can form explosive mixtures with air. Vapors may be heavier than air.
