TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.

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

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION (See Ingestion).
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN MAY BE ABSORBED! (See Ingestion).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES
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 Blue lips or fingernails. Confusion. Headache. Weakness. Dizziness. Nausea. Vomiting. Diarrhoea. Convulsions. Laboured breathing. Unconsciousness.
Do not eat, drink, or smoke during work. Wash hands before eating.
Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Rest. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Do NOT wash away into sewer. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: chemical protection suit including self-contained breathing apparatus).
Provision to contain effluent from fire extinguishing. Separated from acids, bases, iron, food and feedstuffs. Dry. Well closed.
Do not transport with food and feedstuffs.
Severe marine pollutant.

PHYSICAL STATE; APPEARANCE:
PURE: COLOURLESS CRYSTALS ; TECHNICAL: BROWN FLAKES , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes including sulfur oxides, chlorine fumes. Reacts with bases causing toxic (sulfur dioxides fumes) hazard. Attacks iron.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 mg/m3 (as TWA), A4 (skin) (ACGIH 1997).
OSHA PEL†: none
NIOSH REL: TWA 0.1 mg/m3 skin
NIOSH IDLH: N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin, and by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the central nervous system, blood , resulting in irritability, convulsions and renal failure. Exposure at high levels may result in death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Melting point: (technical) 70-100°C; (pure) 106°C
Density: 1.7
g/cm3
Solubility in water: none
Vapour pressure, Pa at 80°C: 1.2
Octanol/water partition coefficient as log Pow: 3.55-3.62

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to birds, and soil organisms. In the food chain important to humans, bioaccumulation takes place, specifically in aquatic organisms. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use.

N O T E S

Use of alcoholic beverages enhances the harmful effect. If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s). Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Beosit, Chlortiepin, Cyclodan, Devisulphan, Endocel, Endosol, Hildan, Insectophene, Malix, Rasayansulfan, Thifor, Thimul, Thiodan, Thionex, and Thiosulfan are trade names.
Transport Emergency Card: TEC (R)-61G41b.
