3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW:
DANGER! POISON! CORROSIVE! An off-white to straw yellow liquid with a
sharp, pungent odor that causes irreversible eye and skin damage. May be
fatal if swallowed, inhaled or absorbed through skin and eyes. Is a
cholinesterase inhibitor. Rapidly absorbed through skin. Repeated inhalation
or skin contact may, without symptoms, progressively increase susceptibility to
organophosphate (including Naled) poisoning. May be an aspiration hazard.
May cause an allergic reaction.
Product is combustible.
Toxic to fish, birds, and other wildlife.
POTENTIAL HEALTH EFFECTS
ROUTE(S) OF ENTRY: May be fatal if swallowed, inhaled or absorbed through skin and eyes. 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.

3. HAZARDS IDENTIFICATION, cont'd
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.
CARCINOGENICITY: 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® 14 CONCENTRATE (High Flash) 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.

4. FIRST AID MEASURES, cont'd
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.
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.
