Physical dangers Inhalation risk
The vapour is heavier than air and may travel along the ground; A harmful contamination of the air can be reached very quickly on
distant ignition possible. evaporation of this substance at 20/C.
Chemical dangers Effects of short-term exposure
The substance decomposes on heating or on burning producing The substance and the vapour is corrosive to the eyes, the skin
toxic fumes including nitrogen oxides. The substance is a weak and the respiratory tract. Inhalation of the vapour may cause lung

explosion hazard. Attacks some metals in presence of water. observation is indicated.
Occupational exposure limits Effects of long-term or repeated exposure
TLV: 5 ppm (Ceiling value); (skin); (ACGIH 200). Repeated or prolonged contact with skin may cause dermatitis.
MAK: 5 ppm 15 mg/m 3; Peak limitation category: I(2); skin
absorption (H); Pregnancy risk group: IIc; (DFG 2004).
PHYSICAL PROPERTIES
Boiling point: 78/C Relative vapour density (air = 1): 2.5
Melting point: -50/C Flash point: -12/C c.c.
Relative density (water = 1): 0.74 Auto-ignition temperature: 312/C
Solubility in water: miscible Explosive limits, vol% in air: 1.7-9.8
Vapour pressure, kPa at 20/C: 10.9 Octanol/water partition coefficient as log Pow: 0.86
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
The occupational exposure limit value should not be exceeded during any part of the working exposure.
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 sections Occupational Exposure Limits, Emergency Response.
