  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, powder, foam, carbon dioxide.   

 PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  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 Diarrhoea. Nausea. Vomiting.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into sealable containers. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT wash away into sewer.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
GREYISH-YELLOW POWDER. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Decomposes on heating and on contact with acids and moisture. This produces toxic and irritating fumes including sulfur oxides, nitrogen oxides, zinc oxide, manganese oxide, hydrogen sulfide, carbon sulfide, ethylene thiuram sulfide, ethylene bisisothiocyanate, ethylene urea and 2-mercaptoimidazoline. 

Formula: C4H6N2S4Mn . C4H6N2S4Zn

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 irritating to the eyes and respiratory tract. The substance is mildly irritating to the skin. 

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

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


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is 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
Maneb, a related substance, may cause also other effects after long-term exposure.
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.
See ICSC1148, 2-Mercaptoimidazoline, a contaminant and breakdown product, ICSC0173 Maneb and ICSC0350 Zineb.
