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 toxic and irritating fumes (hydrogen chloride, ICSC # 0163; chlorine, ICSC # 0126; phosgene, ICSC # 0007).
Reacts violently with some metals such as aluminium, barium, magnesium, potassium, sodium, with fluorine and other substances,
causing fire and explosion hazard.
Attacks copper, lead and zinc.
OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV (as TWA): 5 ppm; 31 mg/m3 A2 (skin) (ACGIH 1992-1993).
MAK: 10 ppm; 65 mg/m3; II,1, H, D (1992).
MAK: class III B (1992).
OSHA PEL: TWA 10 ppm C 25 ppm 200 ppm (5-minute maximum peak in any 4 hours)
NIOSH REL: Ca ST 2 ppm (12.6 mg/m3) 60-minute See Appendix A
NIOSH IDLH: Potential occupational carcinogen 200 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 liver, kidneys and the central nervous system
, resulting in unconsciousness.
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.

NOTES
|
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.
Ascordin, Katarin, Tetracol, Chlorasol are trade names.
