ENVIRONMENTAL DATA |

N O T E S | ||||
Auto-ignition temperature varies from 24°C on a rusty iron surface to 270°C on glass surface.
Depending on the degree of exposure, periodic medical examination is suggested.
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.
The odour warning when the exposure limit value is exceeded is insufficient.
Rinse contaminated clothes (fire hazard) with plenty of water.
Other UN numbers are: UN 2030 Hydrazine hydrate or Hydrazine, aqueous solutions with 37-64% of hydrazine; UN 3293 Hydrazine, aqueous solutions with not more than 37% of hydrazine.
