Maneb is a yellow powder or crystalline solid
with a faint odor. | [Potential Exposure]
A potential danger to those involved
in manufacture, formulation, and application of this broad
spectrum dithiocarbamatefungicide. Some dithiocarbamates
have been used as rubber components. DFG warns of danger of skin sensitization. The BPS Pesticide incident in
West Helena, AK resulted in an explosion and death of
three firemen. The burning of a 1000-lb sack of Azinphos
Methyl or the flashing of Maneb which was present on the
facility may have caused the explosion | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions,
including resuscitation mask) if breathing has stopped and
CPR if heart action has stopped. Transfer promptly to
a medical facility. When this chemical has been swallowed,
get medical attention. Give large quantities of water and
induce vomiting. Do not make an unconscious person
vomit. | [Shipping]
UN2210 Maneb or Maneb preparations with
not <60% maneb, Hazard Class: 4.3; Labels: 4.3-Dangerous
when wet material, 4.2-Spontaneously combustible material. UN2968 Maneb stabilized or Maneb preparations,
stabilized against self-heating, Hazard Class: 4.3; Labels:
4.3-Dangerous when wet material | [Incompatibilities]
Incompatible with oxidizers (chlorates,
nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires
or explosions. Keep away from alkaline materials, strong
bases, strong acids, oxoacids, epoxides, water.
Dithiocarbamate esters are combustible. They react violently with powerful oxidizers such as calcium hypochlorite. Poisonous gases are generated by the thermal
decomposition of Dithiocarbamate compounds, including
carbon disulfide, oxides of sulfur, oxides of nitrogen,
hydrogen sulfide, ammonia, and methylamine. Thio and
dithiocarbamates slowly decompose in aqueous solution
to form carbon disulfide and methylamine or other
amines. Such decompositions are accelerated by acids.
Flammable gases are generated by the combination of
dithiocarbamate with aldehydes, nitrides, and hydrides.
Dithiocarbamate are incompatible with acids, peroxides,
and acid halides. | [Waste Disposal]
Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA
regulations governing storage, transportation, treatment,
and waste disposal. Maneb is unstable to moisture and is
hydrolyzed by acids and hot water. It decomposes at about
100℃ but may spontaneously decompose vigorously when
stored in bulk. Incineration is the preferred disposal
means. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package
label directions or by contacting your local or federal environmental control agency, or by contacting your regional
EPA office |
