Important Data
|
Physical State; Appearance:
COLOURLESS
TO YELLOW
,
VISCOUS
,
HYGROSCOPIC LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air.
Chemical Dangers:
The substance decomposes
on burning
producing
toxic and corrosive gases
including
nitrogen oxides
.
The solution in water is a strong base, it reacts violently with acid and is corrosive.
Reacts violently with oxidants, nitric acid, and organic nitro compounds.
Attacks many metals in presence of water.
Occupational Exposure Limits:
TLV: 1 ppm as TWA; (skin); (ACGIH 2004).
MAK: sensitization of skin (Sh); (DFG 2004).
OSHA PEL: none
NIOSH REL: TWA 1 ppm (4 mg/m3) skin
NIOSH IDLH: N.D. See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour,
through the skin
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is corrosive to
the eyes,
the skin
and
the respiratory tract.
Corrosive on ingestion.
Inhalation of the vapour may cause lung oedema (see Notes).
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
Repeated or prolonged contact may cause skin sensitization.
Repeated or prolonged inhalation exposure may cause asthma.

Environmental
Data
|
|
|
N O T E S
|
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.
