Specialhazards arising from the chemical: High thermal decomposition makes toxic andharmful substances. Liquid gas leakage vaporization, a lot of heat absorptionfrom the surrounding, can cause skin injury. In the closed space leakage, thereis a possibility of suffocation, so the room, so fully ventilation is necessary.Inhalation of high concentrations of gas, may cause general paralysis andsimilar symptoms. Continuous direct contact, inhalation, may occur dizzinessheadache, slow, panting, confusion, movement disorders and other temporarynerve paralysis, hypofunction and other symptoms, serious can lead toarrhythmia and even cardiac arrest.
Specialprotective actions for fire-fighters: The substance is an inflammable liquefiedgas. The container may explode when exposed to high heat in a fire.
