Toxic to fish, birds, and other wildlife.

3. HAZARDS IDENTIFICATION

POTENTIAL HEALTH EFFECTS

ROUTE(S) OF ENTRY: May be fatal if swallowed, inhaled, or absorbed through eyes or skin. May

produce acute cholinesterase depression. May cause corrosive destruction of the skin,

mucous membranes and the eyes.

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.

This product is expected to be corrosive to the eyes. The degree of injury will depend on the

amount and duration of the contact and the speed and thoroughness of the first aid

treatment. Expected adverse health effects resulting from direct exposure to the eye may

include pain, tears, swelling, redness, blurred vision, irreversible eye damage and possibly

blindness.

This product is expected to be corrosive to the skin. The degree of injury will depend on the

amount and duration of the contact and the speed and thoroughness of the first aid

treatment. The expected adverse health effects resulting from a direct exposure to the skin

may include pain or a feeling of heat, discoloration, swelling, blistering, and irreversible

tissue damage.

This product is expected to be corrosive to the digestive tract, and, if ingested, may cause

nausea, vomiting and diarrhea.

This product is expected to be corrosive to the respiratory tract, and, if inhaled, may cause

symptoms that include nasal discharge, sore throat, coughing, bronchitis, pulmonary edema,

and difficulty in breathing.

SIGNS OF CHRONIC OVEREXPOSURE: Repeated exposures to small doses of Naled and other

organophosphates may lower the cholinesterase to levels where the above symptoms of

acute overexposure are observed.

3. HAZARDS IDENTIFICATION, cont'd

CARCINOGENICITY: There is no evidence of carcinogenicity in laboratory animals tested with Naled

Technical. EPA under its 1999 proposed Guidelines for Carcinogen Risk Assessment has

classified DDVP, an impurity in Naled, as having "suggestive evidence of carcinogenicity,

but not sufficient to assess human carcinogenic potential.". IARC lists DDVP (Dichlorvos)

as being possibly carcinogenic to humans (Group 2B). Based on the results of testing in

mice, the IARC has recently classified Naphthalene, a component of the solvent used for this

formulation, as being possibly carcinogenic to humans (Group 2B). CARE SHOULD BE

EXERCISED IN HANDLING THIS FORMULATION.

MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Preexisting 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;

benzalkonium salts, organic mercury compounds, ciguatoxins or solanines; and (for RBC)

hemolytic anemias.

4. FIRST AID MEASURES

DIBROM® 8 Emulsive CONTAINS A CHOLINESTERASE INHIBITOR (NALED). A PHYSICIAN

SHOULD BE CONTACTED IN ALL CASES OF EXPOSURE TO NALED AND ITS

FORMULATIONS. THIS PRODUCT IS CORROSIVE TO EYES AND SKIN.

EYES: Immediately flush the eyes with copious amounts of clear, cool running water for a minimum

of 15 minutes. Hold the eyelids apart during the flushing to ensure rinsing of the entire

surface of the eyes and lids with water. Contact a physician immediately. If there will be a

delay in getting medical attention, rinse the eyes for at least another 15 minutes.

INHALATION: Remove victim to fresh air. If breathing has ceased, clear the victim's airway and

start mouth-to-mouth artificial respiration. If breathing is difficult, give oxygen. Contact a

physician immediately.

INGESTION: DO NOT induce vomiting. If victim is conscious, administer an 8 oz. glass of water

containing 2 tbsp. activated charcoal. Have person lie on their left side to slow down

absorption of the ingested material. Never give anything by mouth to an unconscious

person. Contact a physician immediately.

SKIN: Immediately flush all affected areas with large amounts of clear water for at least 15 minutes.

Remove contaminated clothing. Do not attempt to neutralize with chemical agents. Wash

clothing before reuse. Contact a physician immediately.

NOTE TO PHYSICIANS: This is an Organophosphate (OP) Insecticide. Do not wait for laboratory

confirmation to treat patients with strong clinical evidence of poisoning. In the USA and

other countries, contact your local or national poison control center for more information.

4. FIRST AID MEASURES, cont'd

Do Not handle the patient without the following protective equipment in place: chemical

resistant gloves and apron (preferably nitrile). Remove contaminated clothing and do not

reuse without thorough cleaning with detergent and hot water. Dispose of heavily

contaminated clothing, including shoes, as a hazardous waste.

Establish airway and oxygenation. IV Atropine sulfate 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 g in adults or 20-50 mg/kg in children may be repeated in 1 to 2 hours if muscle

weakness, twitching, and/or respiratory depression persist. Avoid morphine, aminophylline,

phenothiazines, reserpine, furosemide and ethacrynic acid.

Bathe and shampoo contaminated skin and hair. If ingested, empty stomach. Due to the

presence of aromatic solvents, gastric lavage should be considered following intubation with

a cuffed endotracheal tube to prevent aspiration of vomitus. Activated charcoal is useful to

further limit absorption.
