TYPES OF HAZARD
/ EXPOSURE
ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE-FIGHTING
FIRE Combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames. NO contact with water.  Use carbon dioxide, dry powder. NO hydrous agents. NO water. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!   
Inhalation Cough. Sore throat.  Use local exhaust or breathing protection.  Fresh air, rest. 
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   Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
YELLOW POWDER OR CRYSTALS. 

Physical dangers
 

Chemical dangers
Decomposes on contact with acids or moisture. This produces toxic and flammable gases including hydrogen sulfide and carbon disulfide. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: Sensitization of skin (SH); (DFG 2003). 

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, skin and respiratory tract. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the kidneys and central nervous system. This may result in kidney impairment and neurologic and neuropsychiatric disorders (manganism). 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Decomposes at 192-204°C
Density: 1.92 g/cm³
Solubility in water: very poor 
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
UN number 2968: Haz class 4.3; Pack Group III; Maneb stabilized against self-heating.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
Chloroble M, Dithane M 22, Kypman 80, Manebgan, Manesan, Manzate, Polyram M, Rhodianebe, Sopranebe and Trimangol are trade names.
