TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible under specific conditions. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! STRICT HYGIENE!   
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
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   Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL

IMPORTANT DATA
Physical State; Appearance
WHITE OR COLOURLESS CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes above 102°C . This produces toxic fumes including nitrogen oxides and sulfur oxides. Decomposes on contact with acids. This produces carbon disulfide. Decomposes on contact with water or moisture. This produces toxic gases. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of short-term exposure
The substance is irritating to the eyes. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 104-105°C
Relative density (water = 1): 1.3
Solubility in water, g/100ml at 20°C: 0.3
Flash point: 93°C
Octanol/water partition coefficient as log Pow: 1.4  
The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to plants. Avoid release to the environment in circumstances different to normal use. 

NOTES
The technical grade is 98% pure; dazomet is moderately stable but is sensitive to temperature > 35°C and to moisture.
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.
