| Hazard Information | Back Directory | [Chemical Properties]
White crystalline solid. Nearly odorless. | [General Description]
Colorless crystals. Used as a soil fumigant to control weeds and insects. | [Air & Water Reactions]
Decomposes in water to yield fumigant vapor. Acidic solution yields carbon disulfide, formaldehyde, and methyl amine. | [Reactivity Profile]
A thiadiazine. | [Potential Exposure]
Dazomet is a dithiocarbamate insecti-
cide, herbicide, fumigant, fungicide, nematicide. It is used
as a soil fumigant used against germinating weed seeds,
soil insects, nematodes, and soil-borne diseases in forest
nursery seed beds, tobacco crops, greenhouse crops, and substrates for potted plants, turf, and ornamentals. It is also
used as an antimicrobial agent for slimicide preparations
and for adhesives, paper-mill slimicide, paint, and cooling
water slimicides. | [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) 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. Do not induce vomiting when
formulations containing petroleum solvents are ingested. | [Shipping]
UN3077 Environmentally hazardous substances,
solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous
hazardous material, Technical Name Required. | [Incompatibilities]
Sensitive to moisture and heat.
Decomposes on heating above 102
C, producing toxic
fumes including nitrogen oxides and sulfur oxides.
Dithiocarbamate esters are combustible. They react vio-
lently with powerful oxidizers such as calcium hypochlo-
rite. 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]
Do not discharge into drains
or sewers. Dispose of waste material as hazardous waste
using a licensed disposal contractor to an approved landfill.
Consult with environmental regulatory agencies for guid-
ance on acceptable disposal practices. Generators of waste
containing this contaminant (≥100 kg/mo) must conform
with EPA regulations governing storage, transportation,
treatment, and waste disposal. A potential candidate for
liquid injection incineration at a temperature range of
650℃
to 1600℃
and a residence time 0.1 to 2 seconds.
Also, a potential candidate for rotary kiln incineration at a
temperature range of 820℃
to 1600℃
and residence times
of seconds for liquids and gases, and hours for solids
.In
accordance with 40CFR165, follow recommendations for
the disposal of pesticides and pesticide containers.
Containers must be disposed of properly by following
package label directions or by contacting your local or
federal environmental control agency, or by contacting your
regional EPA office. |
