PHYSICAL STATE; APPEARANCE:
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 hydrogen chloride (see ICSC # 0163), phosgene (see ICSC # 0007), and other toxic gases.
Reacts with strong oxidizers, strong bases and metals such as sodium, potassium, magnesium and powdered aluminium.
Attacks many plastics, rubber, steel and zinc.
OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 10 ppm; 55 mg/m3 (as TWA) (skin) (ACGIH 1993-1994).
OSHA PEL: TWA 10 ppm (45 mg/m3) skin
NIOSH REL: Ca TWA 10 ppm (45 mg/m3) skin See Appendix A See Appendix C (Chloroethanes)
NIOSH IDLH: Potential occupational carcinogen 100 ppm
|
ROUTES OF EXPOSURE:
The substance can be absorbed into the body
by inhalation of its vapour,
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 may cause effects on the central nervous system, kidneys, liver
, resulting in central nervous depression, liver impairment and kidney impairment.
Exposure at high levels may result in unconsciousness.
EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.

N O T E S
|
Flash point unknown in literature.
Combustible vapour/air mixtures difficult to ignite, may be developed under certain conditions.
Use of alcoholic beverages enhances the harmful effect.
The relation between odour and the occupational exposure limit cannot be indicated.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
