| Hazard Information | Back Directory | [Chemical Properties]
Parathion is a clear liquid when fresh; pale
yellow to dark brown liquid with a garlic-like odor.
Commercial formulations use carrier solvents that may
change the physical properties shown. | [Potential Exposure]
A severely hazardous pesticide formulation.
Those exposed include those engaged in manufacture,formulation and application of this broad spectrum insecticide.
This material has also been used as a chemical warfare agent. | [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.
Medical observation is recommended for 2448 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]

Poisonous materials. | [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. Strong oxidizers may cause
release of toxic phosphorus oxides. Organophosphates, in
the presence of strong reducing agents such as hydrides,
may form highly toxic and flammable phosphine gas. Keep
away from alkaline materials. Attacks some plastics, rubbers,
and coatings. Rapidly hydrolyzed by alkalis. | [Waste Disposal]
Consult with environmental
regulatory agencies for guidance 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. 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. One manufacturer recommends the
use of a detergent in a 5% trisodium phosphate solution
for parathion disposal and cleanup problems. For parathion
disposal in general, however, the recommended
method is incineration (816°C, 0.5 second minimum for
primary combustion; 1204°C, 1.0 second for secondary
combustion) with adequate scrubbing and ash disposal
facilities. |
