MANEB ICSC: 0173
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
YELLOW POWDER OR CRYSTALS

CHEMICAL DANGERS:
The substance decomposes on contact with acids and moisture producing toxic and flammable gases including hydrogen sulfide and carbon disulfide.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: 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 20C 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, the skin and the 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, resulting in kidney impairment and neurologic, neuropsychiatric disorders (manganism).
PHYSICAL PROPERTIES
Decomposes below melting point at 192-204C
Density: 1.92 g/cm
Solubility in water: very poor
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be given to avoid any additional release, e.g. 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.
