Important Data
|
Physical State; Appearance:
HYGROSCOPIC
PELLETS
OR FLAKES
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
Chemical Dangers:
On combustion, forms toxic and corrosive gases.
Upon heating, toxic fumes are formed.
The solution in water is a strong base, it reacts violently with acid and is corrosive.
Reacts with oxidants.
Attacks many metals in presence of water.
Occupational Exposure Limits:
TLV: 0.5 ppm as TWA; (ACGIH 2004).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol,
through the skin
and
by ingestion.
Inhalation Risk:
A harmful contamination of the air can be reached rather quickly 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 substance 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.

|
|
N O T E S
|
The substance may exist as solid or liquid depending on ambient temperature.
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.
The recommendations on this Card also apply to Hexamethylenediamine solution, 70-80 %, UN No. 1783.
