First Aid Measures

Ingestion

Do not induce emesis. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.

Inhalation

Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.

Skin

Remove contaminated clothing and jewelry. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing. Systemic absorption - there is little evidence that fluoroacetate can be absorbed systemically in toxic amounts through intact skin (ellenhorn & barceloux, 1988). Should systemic symptoms develop following dermal contact with this material - treatment should include recommendations listed in the inhalation exposure section when appropriate.

Eyes

Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. Systemic toxicity - there is no evidence that fluoroacetate can be absorbed in toxic quantities following ocular exposure. Should systemic symptoms develop following exposure by this route - treatment should include recommendations listed in the inhalation exposure section when appropriate.

Handling and Storage

Storage

Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.

Handling

All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Hazards Identification

Inhalation

Respiratory depression and cyanosis may develop. Death may be due to hypoxia and respiratory depression during seizures.

Eyes

Blurred vision, facial paresthesias, and hypersalivation may be noted.

Ingestion

Nausea, vomiting, hypersalivation, abdominal or epigastric pain, and diarrhea may be seen.

Hazards

Very toxic fumes of fluoride may be emitted in a fire.

Exposure Controls/Personal Protection

Personal Protection

Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.

Respirators

Use NIOSH/MSHA approved respirator appropriate for exposure of concern.

Exposure Effects

Respiratory depression, reduced body temperature, rapid heart rate, and abnormally low blood pressure may occur. Apprehension, diaphoresis, disorientation, agitation, paresthesias, muscle twitching, hyperactive behavior, tingling, coma, and convulsions may develop.

Fire Fighting Measures

Flash Point

31

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.

Accidental Release Measures

Small spills/leaks

Avoid inhalation and skin contact. (Non-Specific -- Fluoroacetic Acid) Do not touch spilled material; stop leak if you can do so without risk. Use water spray to reduce vapors. Small spills: absorb with sand or other noncombustible absorbent material and place into containers for later disposal. Large spills: dike far ahead of spill for later disposal.

Stability and Reactivity

Stability

No data.

Incompatibilities

Strong oxidizing agents.
