| Hazard Information | Back Directory | [Potential Exposure]
A potential danger to those involved
in the manufacture, formulation, and application of this
systemic insecticide and acaricide. | [First aid]
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration
with the aid of a pocket mask equipped with a one-way valve
or other proper respiratory medical device. Administer oxy-
gen if breathing is difficult. Remove and isolate contami-
nated clothing and shoes. In case of contact with substance,
immediately flush skin or eyes with running water for at
least 20 minutes. For minor skin contact, avoid spreading
material on unaffected skin. Keep victim warm and quiet.
Effects of exposure (inhalation, ingestion, or skin contact) to
substance may be delayed. Ensure that medical personnel are
aware of the material(s) involved and take precautions to
protect themselves. Medical observation is recommended for
24 to 48 hours after breathing overexposure, as pulmonary
edema may be delayed. As first aid for pulmonary edema, a
doctor or authorized paramedic may consider administering
a drug or other inhalation therapy | [Shipping]

Demeton is a light brown liquid with an odorof sulfur compounds; Freezing/Melting point #213℃.Molecular weight = 516.92; Boiling point =134℃ at2 mmHg at 20℃; Flash point =45℃; Explosive limits:LEL = 1%; UEL = 5.3%. Hazard Identification (based onNFPA-704 M Rating System): Health 3, Flammability 2,Reactivity 0. Insoluble in water. | [Chemical Properties]
Demeton is a light brown liquid with an odor
of sulfur compounds; freezing/melting point ≤‐13
C | [Waste Disposal]
The thiono-and thiolo-isomers of
this mixture are 50% hydrolyzed in 75 minutes and 0.85 min-
ute, respectively @ 20℃
and pH 13. At pH 9 and 70 ℃
, the
half-life of Demeton is 1.25 hour, but an pH 1-5 it is over
11 hours. Sand and rushed limestone may be added together
with a flammable solvent; the resultant mixture may be burned
in a furnace with afterburner and alkaline scrubber
.In
accordance with 40CFR165, follow recommendations for the
disposal of pesticides and pesticide containers. Must be dis-
posed properly by following package label directions or by
contacting your local or federal environmental control agency,
or by contacting your regional EPA office. | [Uses]
Demeton-O is an organophosphorus pesticide found in some imported crops and fruits samples. | [Definition]
ChEBI: Demeton-O is an organic thiophosphate. | [storage]
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with demetonyou should be trained on its proper handling and storage. Aregulated, marked area should be established where thischemical is handled, used, or stored in compliance withOSHA Standard 1910.1045. Before entering confined spacewhere this chemical may be present, check to make surethat an explosive concentration does not exist. Store inDemeton 861tightly closed containers in a cool, well-ventilated areaaway from oxidizers, strong bases, water, soluble mercury,and other pesticides. Where possible, automatically pumpliquid from drums or other storage containers to processcontainers. |
