This material is highly toxic; it is capable of causing death or permanent injury by exposure during normal use. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
1. insure that a clear airway exists by aspiration of secretions if necessary. admin oxygen by mechanically assisted pulmonary ventilation if respiration is depressed. improve tissue oxygenation as much as possible before admin atropine to minimize risk of ventricular fibrillation. in severe poisonings, it may be necessary to support pulmonary ventilation mechanically for several days. 2. admin atropine sulfate iv, or im if iv injection is not possible. ... in moderately severe poisoning: adult dosage and children over 12 yr: 0.4-2.0 mg repeated every 15 min until atropinization is achieved. maintain atropinization with repeated dosage of 0.02-0.05 mg/kg body weight. organophosphate pesticides

Environmental precautions
Prevent further spillage or leakage if it is safe to do so. Do not let the chemical enter drains. Discharge into the environment must be avoided.
Methods and materials for containment and cleaning up
1. ventilate area of spill or leak. 2. collect for reclamation, or absorb in vermiculite, dry sand, earth, or a similar material. parathion
SECTION 7: Handling and storage

Appropriate engineering controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures, such as personal protective equipment (PPE)
Wear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

SECTION 10: Stability and reactivity
Reactivity
No rapid reaction with air. No rapid reaction with water.
Chemical stability
Stable @ normal temperatures
Possibility of hazardous reactions
Organophosphates, such as LEPTOPHOS, 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.
Conditions to avoid

Persistence and degradability
In die-away tests using a natural water (pH 7 collected from a drainage ditch in a vegetable growing area of Canada), sterilized natural water, and distilled water, leptophos degraded only slightly more rapidly in the unsterilized natural water over a 16-week incubation period(1); over the 16-week period, approximately 55-60% of the initial leptophos was degraded with removal only several percent more rapid in the unsterilized natural water as compared to the other waters(1); although some biodegradation was occurring, it was concluded that chemical degradation is more important than microbial degradation(1).
Bioaccumulative potential
Residues of leptophos and its metabolites exhibited bioaccumulation factors of 1443 and 48398 in fish and snail, respectively.
Mobility in soil
The adsorption behavior of leptophos in soil and aqueous suspension of soil and sediment was studied in the laboratory(1); based upon results of leaching tests, leptophos was assigned a mobility factor of zero, which indicated that it was not leachable from either sand or various organic soils(1); Freundlich adsorption isotherms measured in a river sediment, sandy loam soil and sand(1) can be used to determine respective log Koc values of 5.07, 4.98 and 4.85(1). An experimentally determined log Koc of 3.97 has also been reported(2). According to a suggested classification scheme(3), these estimated Koc values indicate that leptophos is immobile in soil(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
