Important Data
|
Physical State; Appearance:
BLACK TO BROWN HYGROSCOPIC CRYSTALS
.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating above 200°C
producing
toxic and corrosive gases
including
chlorine
and
hydrogen chloride
.
The substance decomposes
on contact with water
producing hydrogen chloride.
The solution in water is a medium strong acid.
Reacts violently with alkali metals, allyl chloride, ethylene oxide, styrene and bases
causing explosion hazard.
Attacks metal
forming flammable/explosive gas (hydrogen - see ICSC0001)
.
Occupational Exposure Limits:
TLV: (soluble iron salts, as Fe) 1 mg/m3 (ACGIH 2004).
MAK not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
,
the skin
and
the respiratory tract
.
Corrosive on ingestion.
Effects of Long-Term or Repeated Exposure:
|
|
