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. Toxicity of
other components: This product contains a Xylene Range Aromatic Solvent composed of xylenes,
ethylbenzenes and aromatic naphtha containing trimethylbenzenes. Inhalation of solvent vapors at high
concentrations can cause central nervous system depression, respiratory tract irritation, asphyxiation,
cardiac stress, and coma. Exposure to extremely high levels of xylenes may cause kidney or liver
damage.
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:
112o 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.
Ventilation:
Local Exhaust: As required to meet TLV values.
Special: As required to meet TLV values.
Mechanical: As required to meet TLV values.
Other: As required to meet TLV values.
Protective Gloves: Chemical resistant.
Eye Protection: Face shield if there is a chance of splashing, or goggles, or safety glasses.

Other protective clothing or equipment: Wear clothing designed to prevent skin contact, such as long
pants and long 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 maximum possible interval
between treatment and the next period of bee activity. Do not use, pour or spill near heat or open flame.
