3: Hazards Identification:
EMERGENCY OVERVIEW
Danger! Poison! Poisonous if swallowed, inhaled or absorbed through skin and eyes. Rapidly absorbed through
skin. Repeated inhalation or skin contact may, without symptoms, progressively increase susceptibility to
Dichlorvos (DDVP) poisoning.
Routes of Exposure: Inhalation: Yes. Skin: Yes. Ingestion: Yes.
Dichlorvos (DDVP) is poisonous if swallowed, inhaled or absorbed through skin or eyes. Hazards from 1,1,1-
trichloroethane (these effects are secondary to the toxicity of the DDVP in this formulation): Eye: May cause pain
and slight, transient (temporary) irritation with corneal injury. Vapors may irritate eyes. Skin: Prolonged or repeated
contact may cause irritation, drying or flaking. Ingestion: Single oral dose toxicity is low. Inhalation: In confined or
poorly ventilated areas, vapors, which readily accumulate, can cause unconsciousness and death. Minimal narcotic effects
may be seen.
Signs of Acute Overexposure: Acute cholinesterase depression may be evidenced by headache, nausea, vomiting,
diarrhea, abdominal cramps, excessive sweating, salivation, and tearing, constricted pupils, blurred vision, tightness in
chest, weakness, muscle twitching and confusion. In extreme cases, unconsciousness, convulsions, severe respiratory
depression and death may occur.
Signs of Chronic Overexposure: Repeated exposure to small doses of DDVP or other organophosphates may lower the
cholinesterase to levels where the above symptoms of acute overexposure are observed.
Carcinogenicity: NTP: No. IARC Monographs: Possible (Group 2B). OSHA Regulated: No.
EPA has classified Dichlorvos as a Class C possible human carcinogen. CARE SHOULD BE EXERCISED IN
HANDLING THIS PRODUCT.
Medical Conditions Generally Aggravated by Exposure: Pre existing conditions which lower cholinesterase levels
increase vulnerability to cholinesterase depression. These include: (for plasma) genetic cholinesterase deficiency, advanced

liver disease, chronic alcoholism, malnutrition, dermatomyositis, existing toxicity from exposure to carbon disulfide,
bezalkonium salts, organic mercury compounds, ciguatoxins of solanines, and (for RBC) hemolytic anemias.
4: First Aid Measures:
If swallowed: Call a physician or Poison Control Center immediately. Gastric lavage is indicated, if material was taken
internally. Do not induce vomiting unless other treatment is not available. Vomiting may cause aspiration pneumonia. If
it is necessary to induce vomiting, give person one or two glasses of water and insert finger in back of throat. Repeat until
vomit fluid is clear. Do not induce vomiting or give anything by mouth to unconscious person.
If inhaled: Remove person to fresh air. Apply respiration if indicated.
If on skin: Wash immediately with soap and water.
If in eyes: Flush eyes for at least 15 minutes with water.
Note to physicians: Dichlorvos (DDVP) is an Organophosphate (OP) Insecticide and a cholinesterase inhibitor. Do not
wait to treat patients with strong clinical evidence of poisoning. The Health Information Service (HIS) is available for
further recommendations regarding control of poisoning, emergency treatment, and other information regarding the toxicity
of DDVP. The toll free number for HIS is 1-800-228-5635, ext. 169.
Establish airway and oxygenation. IV Atropine is the antidote of choice. Moderately severe poisoning: use 0.4 - 2.0 mg in
adults or 0.05 mg/Kg in children. Repeat every 15 minutes until atropinization is achieved. Severe poisoning may require
larger doses. Cholinergic toxicity may recur as atropinization wears off; monitor patient closely. Draw blood for RBC and
plasma cholinesterase. In addition, pralidoxime (2-PAM) is indicated during the first 36 hours in severe poisonings. Slow
IV administration (no less than 2 minutes) of 1 gm in adults of 20 - 50 mg in children may be repeated in 1 to 2 hours if
muscle weakness, twitching, and/or respiratory depression persist. Avoid morphine, aminphylline, phenothiazines,
reserpine furosemide and ethacrynic acid. Bathe and shampoo contaminated skin and hair. If ingested, empty stomach;
activated charcoal is useful to further limit absorption. If victim is alert, Syrup of Ipecac (2 tablespoons in adults, 1
tablespoon in small children) followed by water (2 glasses for adults, 1 glass for children) is indicated. If symptoms such
as loss of gag reflex, convulsions, or unconsciousness occur before emesis, gastric lavage should be considered following
intubation with a cuffed endotracheal tube.

5: Fire Fighting Measures:
148o F. closed cup.
Flash Point (Method Used):
Flammable Limits: LEL: 1.9 UEL: 12.6 (Solvent - approximate)
Extinguishing Media: CO2, Foam, Dry Chemical, water spray.
Special Fire Fighting Procedures: Fight fire from upwind position. Use self contained breathing apparatus and
equipment designed to prevent skin and eye contact. Cool exposed containers with water spray. This product is toxic to
birds, fish and other wildlife. Prevent spread of contaminated runoff.
Unusual Fire and Explosion Hazards: May give off hydrogen chloride, CO, phosphorus oxides and other carbon oxides.
Foam is preferred method of fighting fires to help prevent spread of contaminated runoff.
6: Accidental Release Measures:
Steps to be taken in case material is released or spilled: Evacuate personnel and thoroughly ventilate the area. Use
adequate ventilation and air supplied respirators, as well as impervious clothing and safety goggles. Keep bystanders
upwind and away from the spill.
Small spill: Cover with absorbent material, such (clay, sawdust, straw, kitty litter, etc.) to absorb the liquid. Sweep onto a
shovel and put the sweepings into a salvage drum. Decontaminate the area and equipment with dilute alkalai or ammonia
(less than 5% solution) and detergent. Flush the area with water. Absorb and sweep into the same salvage drum. Close
the drum and dispose of as a hazardous waste. Place any leaking container into another salvage drum.
Large spill: Dike the spill to prevent contamination of local water sources. Siphon the majority of the liquid into drums
for use or disposal, depending on the circumstances. Clean the area as described for a small spill.
7: Handling and Storage:
Handling: Do not contaminate water, food or feed by storage or disposal. Store in a dry place away from temperature
extremes. Avoid inhalation of vapors. Poisonous if swallowed, inhaled or absorbed through skin. Avoid contact with
skin. Wear clean protective clothing. Wash thoroughly and change clothes after handling.
Storage: Do not contaminate water, food or feed by storage or disposal. Store in a cool, dry, locked place out of reach of
children.
Other precautions: Periodically inspect stored materials.
8: Exposure Control/Personal Protection:
Respiratory protection: Wear a pesticide respirator jointly approved by the Mining Enforcement and Safety
Administration (formerly US Bureau of Mines) and the National Institute for Occupational Safety and Health (NIOSH),
under the provisions of 30 CFR Part II, for DDVP protection.

sleeved shirt, or overalls, shoes with socks and headgear for overhead exposure.
Work/Hygienic practices: Poisonous if inhaled, absorbed through skin or eyes. Do not get in eyes, or on skin. Do not
breathe fumes. Rapidly absorbed through skin. Wear chemical resistant gloves, protective clothing, and goggles when
handling. Wash hands, arms and face thoroughly with soap and water before eating or smoking. Wash all contaminated
clothing with soap and hot water before reuse. Keep all unprotected persons out of operational area. Do not allow children
or pets to contact treated areas until spray has dried. This product is toxic to fish, birds and other wildlife. Birds and other
wildlife feeding in treated areas may be killed. Do not apply directly to water. Do not apply this product when weather
conditions favor drift from areas treated. Do not contaminate water by cleaning of equipment or disposal of wastes. This
pesticide is highly toxic to bees exposed to direct treatment or residues remaining on the treated area. Do not apply when
bees are actively visiting vegetation or weeds blooming in the treatment area. Applications should be timed to provide
