This material is super toxic; the probable oral lethal dose for humans is less than 5 mg/kg, or a taste (less than 7 drops) for a 150-lb. person. It has direct and immediate effects whether it is swallowed, inhaled, or absorbed through the skin. (EPA, 1998)
Treatment is the same as that for poisoning by other organic phosphorus cmpd ... The beneficial effects of oximes in people poisoned by mevinphos have been noted in several cases ... but not in all ... The importnace of thorough bathing is emphasized by a case in which continuing illness suggested continuing dermal absorption.
If material is on fire or involved in a fire: Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog. Solid streams of water may be ineffective. Cool all affected containers with flooding quantities ofwater. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide. keep run-off water out of sewers and water sources.
Fire may produce irritating or poisonous gases. Runoff from fire control may give off poisonous gases and also cause pollution. When heated to decomposition, it emits toxic fumes of phosphorus oxides. Avoid strong oxidizers. Avoid temperatures above 77-86F, sources of heat, fire, free flames or spark-generating equipment. (EPA, 1998)
Wear self-contained breathing apparatus for firefighting if necessary.
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Do NOT wash away into sewer. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.
If phosdrin is spilled or leaked ... collect for reclamation or absorb in vermiculite, dry sand, earth or similar material.
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Separated from food and feedstuffs and strong oxidants. Keep in a well-ventilated room. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.Rooms used for storage only should be soundly constructed & fitted with secure locks. Floors should be kept clear & pesticides clearly identified. If repacking is carried out in storage rooms, adequate light should be available; floors should be impervious & sound . Pesticides

Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
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.

Mevinphos is a pale yellow to orange liquid, with a weak odor. Used as an insecticide and acaricide on vegetables, alfalfa, deciduous fruits and nuts. (EPA, 1998) May be found in the form of a dry mixture where the liquid is absorbed onto a dry carrier.

Decomposes on heating. This produces toxic and corrosive fumes including phosphoric acid and phosphorus oxides. Reacts violently with strong oxidants. This generates fire and explosion hazard. Attacks iron, stainless steel, brass, some forms of plastic, rubber and coatings.

Organophosphates, such as MEVINPHOS, 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.

In laboratory studies in Chehalis clay loam, 95% of the applied mevinphos degraded in 1 day(1). An enzyme was found to be responsible for the degradation which was heat labile(1). Another investigator, who did hydrolysis studies of mevinphos in water, reported that mevinphos degradation in soil was generally rapid with a half-life of 2-12 hr(2). This degradation rate, which is much more rapid than the rate of hydrolysis in water at pH 9(2), is consistent with a microbially-mediated process(SRC).
Using an estimated log Kow of -0.24(1), one would estimate a BCF of 0.4 for mevinphos using a recommended regression equation(2). This would indicate that mevinphos would not bioconcentrate in aquatic organisms. Bioaccumulation of mevinphos may be unlikely in some systems because it is metabolized in some animals(3).
The amount of mevinphos bound by soils increased with increasing orgainc content. ... soil moisture has a major influence on the availability and extractability of residues of organophosphorus pesticides ... because of competition between the insecticides and water for adsorption sites on clay particles. ... mevinphos /when compared to other organophosphorus pesticides/ 1.4-fold more active in moist soils than in dry soils. however, even though there is a major interaction between insecticides and water, it does not appear to move freely in soils with water, and loss by leaching does not appear to be a major factor. ...

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.
