TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION


EXPOSURE
STRICT HYGIENE!

Inhalation Cough. Sore throat. Laboured breathing. Nausea. Vomiting. Convulsions.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin Redness. Pain.
Protective gloves.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness. Pain.
Face shield, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Abdominal cramps. (Further see Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING

TRICHLOROMETHANESULFENYL CHLORIDE ICSC: 0311
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
YELLOW, OILY LIQUID, WITH PUNGENT ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes including hydrogen sulfide and sulfur oxides. The substance decomposes on contact with water producing hydrogen chloride, sulfur dioxide and carbon dioxide. Reacts with bases, oxidants and reducing agents. Attacks many metals.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 ppm (ACGIH 2003).
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 very quickly on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is severely irritating to the eyes, the skin and the respiratory tract. Inhalation of vapour at high concentrations may cause lung oedema (see Notes). Exposure above the OEL may result in death. The effects may be delayed. Medical observation is indicated.

PHYSICAL PROPERTIES
Boiling point: 147-148C
Relative density (water = 1): 1.7
Solubility in water: none
Vapour pressure, kPa at 20C: 0.4
Relative vapour density (air = 1): 6.4
ENVIRONMENTAL DATA

NOTES
Environmental effects from the substance have not been investigated adequately. 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 are therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered. The name Perchloromethyl mercaptan is also used for a compound with CAS number 75-70-7 (CCl_3SH).
