Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis.
PHYSICAL PROPERTIES
Boiling point: 76/C Vapour pressure, kPa at 20/C: 13
Melting point: -96/C Relative vapour density (air = 1): 4.2
Relative density (water = 1): 1.5 Relative density of the vapour/air-mixture at 20/C (air = 1): 1.4
Solubility in water: reaction Flash point: 75/C
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
Reacts violently with fire extinguishing agents such as 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 is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Card has been partly updated in October 2005. See section Emergency Response.
