	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.	NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.	Use water spray, foam, powder, carbon dioxide.

PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. Abdominal pain. Nausea. Vomiting.	Use local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness. Pain.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	Wear safety goggles or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Abdominal pain. Nausea. Vomiting.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE POWDER. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. Chemical dangers Decomposes on heating and on burning. This produces toxic and irritating fumes including nitrogen oxides and sulfur oxides. Decomposes on contact with acids.	Formula: ((CH₃)₂NCS.S)₂Zn / C₆H₁₂N₂S₄Zn Molecular mass: 305.8 Melting point: 240-250°C Density: 1.7 g/cm³ Solubility in water: very poor Octanol/water partition coefficient as log Pow: 1.09

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. Effects of short-term exposure The substance is severely irritating to the eyes. The substance is irritating to the skin and respiratory tract.	Inhalation risk A harmful concentration of airborne particles can be reached quickly when dispersed. Effects of long-term or repeated exposure Repeated or prolonged contact may cause skin sensitization. Tumours have been detected in experimental animals but may not be relevant to humans.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

Effects of short-term exposure
The substance is severely irritating to the eyes. The substance is irritating to the skin and respiratory tract.

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed.

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Tumours have been detected in experimental animals but may not be relevant to humans.

OCCUPATIONAL EXPOSURE LIMITS
MAK: (inhalable fraction): 0.01 mg/m³; peak limitation category: I(2); sensitization of skin (SH); pregnancy risk group: C

ENVIRONMENT
The substance is very toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.

NOTES
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.
