FIRE
|
Combustible under specific conditions.
See Notes.
|
|
In case of fire in the surroundings: all extinguishing agents allowed.
|
|
Explosion
|
|
Prevent build-up of electrostatic charges (e.g., by grounding).
|
In case of fire: keep drums, etc., cool by spraying with water.

Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air.
As a result of flow, agitation, etc., electrostatic charges can be generated.
Chemical Dangers:
On contact with hot surfaces or flames this substance decomposes forming
toxic and corrosive fumes
(
phosgene
,
hydrogen chloride
).
The substance decomposes
on contact with strong alkali
producing dichloroacetylene
, which increases fire hazard.
Reacts
violently with metal powders such as magnesium, aluminium, titanium, and barium. Slowly decomposed by light in presence of moisture, with formation of corrosive hydrochloric acid.
Occupational Exposure Limits:
TLV: 50 ppm as TWA; 100 ppm as STEL; A5; BEI issued; (ACGIH 2004).
MAK:
Carcinogen category: 1; Germ cell mutagen group: 3B;
(DFG 2004).
OSHA PEL: TWA 100 ppm C 200 ppm 300 ppm (5-minute maximum peak in any 2 hours)
NIOSH REL: Ca See Appendix A See Appendix C
NIOSH IDLH: Ca 1000 ppm See: 79016
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
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 irritating to
the eyes
and
the skin
.
Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis.
The substance may cause effects on the
central nervous system
, resulting in
respiratory failure
.
Exposure could cause lowering of consciousness.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact with skin may cause dermatitis.
The substance may have effects on the
central nervous system
, resulting in
loss of memory.
The substance may have effects on the
liver
and
kidneys
(see Notes).
This substance is probably carcinogenic to humans.

|
|
N O T E S
|
Combustible vapour/air mixtures difficult to ignite, may be developed under certain conditions.
Use of alcoholic beverages enhances the harmful effect.
Depending on the degree of exposure, periodic medical examination is suggested.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
