INHALATION OR INGESTION: Symptoms secondary to cholinesterase inhibition are: headache, giddiness, nervousness, blurred vision, weakness, nausea, cramps, diarrhea, chest discomfort, sweating, miosis, tearing, salivation, and other excessive respiratory tract secretion, vomiting, cyanosis, muscle twitching, and convulsions. EYES: Irritating. SKIN: Irritating-can cause dermatitis. (USCG, 1999)
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 min, 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. Effects may be delayed. Medical observation is recommended.
Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
May be combustible. (NOAA, 2007)
In case of fire in the surroundings, use appropriate extinguishing media.
Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Sweep spilled substance into covered sealable containers. Carefully collect remainder. Then store and dispose of according to local regulations. If liquid: collect leaking liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

ACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Wear respiratory protection. Avoid dust formation. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Methods and materials for containment and cleaning up: Pick up and arrange disposal without creating dust. Sweep up and shovel. Keep in suitable, closed containers for disposal.
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.

Naled is a white solid that may be dissolved in a liquid organic carrier with a pungent odor. It is a water emulsifiable liquid. It is insoluble in water and sinks in water. It can cause illness by inhalation, skin absorption and/or ingestion. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. If it is in liquid form, it can easily penetrate the soil and contaminate groundwater and nearby streams. It is used as a pesticide.

Decomposes on heating and on contact with acids and oxidants. This produces toxic and corrosive fumes including hydrogen bromide, hydrogen chloride and phosphorus oxides. Decomposes on contact with water. This produces dichlorvos and dichloroacetaldehyde. Attacks metals, plastics, rubber and coatings.
Stable under recommended storage conditions.
Not combustible. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.NALED is incompatible with the following: Strong oxidizers, acids, sunlight, water [Note: Corrosive to metals. Hydrolyzed in presence of water.] (NIOSH, 2016). Unstable in presence of Iron (USCG, 1999). Organophosphates 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.

The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the nervous system. This may result in convulsions and respiratory depression. Cholinesterase inhibition. Exposure far above the OEL could cause death. The effects may be delayed. Medical observation is indicated.
Cholinesterase inhibition. Cumulative effects are possible. See Acute Hazards/Symptoms.
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.
AEROBIC: As a chemical class, the organophosphorus insecticides, such as naled, are generally considered to be biodegradable(1). The metabolism of naled in unsterile sandy loam was 3 times faster than in sterile sandy loam, and was 2-3 times faster than in sand, loam, and silt soils(2). The half-lives were 1.4 and 4 hours, respectively, for unsterile and sterile sandy loams. The half-lives for naled ranged from 2.6 to 4.0 hours for other soil types; DDVP was detected in all soil samples(2). The metabolism of 14C-labelled naled in Oakly sandy loam soil under aerobic conditions showed that degradation of naled to 14C-carbon dioxide was rapid with a half-life of 3 days(2). In a cranberry bog, the half-life for the aerobic metabolism of 14C-labelled naled was about 6 hours with most of the naled metabolized to carbon dioxide (71% in 30 days)(2).
An estimated BCF of 0.4 was calculated for naled(SRC), using a log Kow of 1.38(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Koc values of 180(1) and 344(2) have been reported for naled. According to a classification scheme(3), these Koc values suggest that naled is expected to have moderate mobility in soil.

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.
