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, chlorine).
The substance decomposes
on contact with strong alkali
producing dichloroacetylene
, which increases fire hazard.
Reacts
violently with metals such as lithium, magnesium aluminium, titanium, barium and sodium. Slowly decomposed by light in presence of moisture, with formulation of corrosive hydrochloric acid.
OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 50 ppm; 269 mg/m3 (STEL): 200 ppm; 1070 mg/m3 (ACGIH 1992-1993).
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: Potential occupational carcinogen 1000 ppm
|
ROUTES OF EXPOSURE:
The substance can be absorbed into the body
by inhalation,
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
irritates
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.
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 liver and kidney
(see notes).

ENVIRONMENTAL DATA
|
This substance may be hazardous to the environment; special attention should be given to water organisms.
|
|
NOTES
|
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 indicated.
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.
Technical grades may contain small amounts of carcinogenic stabilizers.
