ENVIRONMENTAL DATA
NOTES
Reacts violently with fire extinguishing agents such as water,
producing explosive gas.
The substance may contain contaminant resulting in the release of the toxic gas phosphine on contact with water.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Also consult ICSC 0089 Acetylene.
Card has been partly updated in October 2005. See section Emergency Response.
