FIRE
|
Flammable.
Gives off irritating or toxic fumes (or gases) in a fire.
|
NO open flames, NO sparks, and NO smoking.
|
Water spray, foam, powder, carbon dioxide.
|
|
Explosion
|
Above 55°C explosive vapour/air mixtures may be formed.
|
Above 55°C use a closed system, ventilation.
|
In case of fire: cool cylinder by spraying with water but avoid contact of the substance with water.

Important Data
|
Physical State; Appearance:
CLEAR, COLOURLESS LIQUID
, WITH CHARACTERISTIC ODOUR.
Physical Dangers:
The vapour is heavier than air.
Chemical Dangers:
The substance can form explosive peroxides on exposure to air and light.
The substance decomposes
on burning or
on contact with water,
producing toxic fumes including hydrogen chloride.
Reacts with strong oxidants.
Reacts violently with chlorosulfonic acid and oleum.
Occupational Exposure Limits:
TLV: 5 ppm as TWA, 10 ppm as STEL; (skin); A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: 10 ppm, 59 mg/m3
Peak limitation category: I(1);
skin absorption (H); (DFG 2004).
OSHA PEL: TWA 15 ppm (90 mg/m3) skin
NIOSH REL: Ca TWA 5 ppm (30 mg/m3) ST 10 ppm (60 mg/m3) skin See Appendix A
NIOSH IDLH: Ca 100 ppm See: 111444
|
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
irritates
the eyes
and
the respiratory tract.
Inhalation of vapour may cause lung oedema (see Notes).
Exposure far above the OEL may result in death.
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.

N O T E S
|
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
Check for peroxides prior to distillation; eliminate if found.
DCEE, Chlorex are trade names.
