Uses
Insecticide, acaricide.
General Description
Yellow to amber liquid. Works as an insecticide and acaricide. Not registered as a pesticide in the U.S.
Reactivity Profile
When heated to decomposition, MEPHOSFOLAN emits very toxic fumes of nitrogen oxides, phosphorus oxides and sulfur oxides. Stable at neutral pH. Hydrolyzed by acid or alkali. [EPA, 1998]. Organophosphates, such as MEPHOSFOLAN, are susceptible to formation of highly toxic and flammable phosphine gas in the presence of strong reducing agents such as hydrides. Partial oxidation by oxidizing agents may result in the release of toxic phosphorus oxides.
Health Hazard
MEPHOSFOLAN is highly toxic if swallowed or absorbed through the skin.
Fire Hazard
When heated to decomposition, MEPHOSFOLAN emits very toxic fumes of nitrogen oxides, phosphorus oxides and sulfur oxides. Stable at neutral pH. Hydrolyzed by acid or alkali.
Potential Exposure
A potential danger to those involved
in the production, formulation, and application of this
insecticide and acaricide. Not currently registered for use in
the US
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. Speed in removing material from skin
is of extreme importance. Shampoo hair promptly if contaminated. 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
N3018 Organophosphorus pesticides, liquid,
toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
UN2810 Toxic liquids, organic, n.o.s., Hazard Class: 6.1;
Labels: 6.1-Poisonous materials, Technical Name Required
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. Similar organic amides
react with azo and diazo compounds, releasing toxic gases.
Contact with reducing agents can release flammable gases.
Amides are very weak bases but they can react as acids,
forming salts. Mixing amides with dehydrating agents
such as such as phosphorus pentoxide or thionyl chloride
generates the corresponding nitrile.
