FIRE
|
Combustible.
Gives off irritating or toxic fumes (or gases) in a fire.
|
NO open flames.
|
Powder, water spray, foam, carbon dioxide.
|
|
Explosion
|
Finely dispersed particles form explosive mixtures in air.
Risk of explosion on contact with many substances.
|
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.
|
In case of fire: keep drums, etc., cool by spraying with water.
Combat fire from a sheltered position.

with
reducing agents
,
strong bases
and
oxidants
causing explosion hazard.
Occupational Exposure Limits:
TLV: 0.2 mg/m3 as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2004).
MAK: skin absorption (H);
Carcinogen category: 2;
(DFG 2004).
TLV and MAK are for mixed isomers (CAS 25321-14-6)
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation,
through the skin
and

The substance may cause effects on the
blood
, resulting in
formation of methaemoglobin.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the
blood
, resulting in
formation of methaemoglobin.
This substance is possibly carcinogenic to humans.
Animal tests show that this substance possibly causes toxicity to human reproduction or development.
