During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Substance is noncombustible. To extinguish fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
This material is probably combustible.
Contact with metals may evolve flammable hydrogen gas.
Fire may produce irritating, corrosive and/or toxic gases.
Abnormally low blood pressure and labored respirations may occur. CNS depression and peripheral neuropathy have been reported after ingestion.
May cause digestive tract disturbances.
May cause respiratory tract irritation. Effects of inhalation may be delayed.
May cause skin irritation. Effects of contact may be delayed.
