PHYSICAL STATE; APPEARANCE:
VOLATILE COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
PHYSICAL DANGERS:
The vapour is heavier than air.
CHEMICAL DANGERS:
On contact with hot surfaces or flames this substance decomposes forming irritating and toxic fumes (hydrogen chloride, ICSC # 0163; phosgene, ICSC # 0007; chlorine, ICSC # 0126).
The substance decomposes slowly
under influence of air and light.
Reacts violently with strong bases, strong oxidants, some metals, such as aluminium, lithium, magnesium, potassium and sodium,
causing fire and explosion hazard.
Attacks plastic, rubber and coatings.
OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV (as TWA): 10 ppm; 50 mg/m3 (ACGIH 1992-1993).
MAK: 10 ppm; 50 mg/m3; II,1, B (1992).
MAK: class III B (1992).
OSHA PEL: C 50 ppm (240 mg/m3)
NIOSH REL: Ca ST 2 ppm (9.78 mg/m3) 60-minute See Appendix A
NIOSH IDLH: Potential occupational carcinogen 500 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 very quickly on evaporation of this substance at 20°C.
EFFECTS OF SHORT-TERM EXPOSURE:
The substance
irritates
the eyes.
The substance may cause effects on the heart, liver, kidneys and the central nervous system
, resulting in unconsciousness.
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.
This substance is possibly carcinogenic to humans.

ENVIRONMENTAL DATA
|
This substance may be hazardous to the environment; special attention should be given to water.
|
N O T E S
|
Turns combustible on addition of small amounts of a flammable substance or an increase in the oxygen content of the air.
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.
