First Aid Measures

Ingestion

Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.

Inhalation

If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention.

Skin

Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. Vitamin e topical application is highly effective in relieving paresthesias.

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.

Handling and Storage

Storage

Pyrethrins with piperonyl butoxide topical preparations should be stored in well-closed containers at a temperature less than 40C, preferably between 15-30C.

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

Ingestion

Nausea, vomiting and abdominal pain commonly occur and develop within 10 to 60 minutes following ingestion.

Inhalation

Hypersensitivity reactions characterized by pneumonitis, cough, dyspnea, wheezing, chest pain, and bronchospasm may occur. Rare cases of respiratory failure and cardiopulmonary arrest have been reported.

Skin

Irritant and contact dermatitis may develop. Erythema which mimics sunburn has also been noted after prolonged repeated exposure.

Exposure Controls/Personal Protection

Personal Protection

Employees should be provided with and required to use dust- and splash-proof safety goggles where pyrethroids may contact the eyes. Pyrethroids.

Respirators

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

Poison Class

3

Fire Fighting Measures

Flash Point

107 (technical grade)

Fire Fighting

Use carbon dioxide, foam, or dry chemical on fires involving pyrethroids.

Fire Potential

Pyrethrins. Burn with difficulty.

Accidental Release Measures

Small spills/leaks

Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.

Stability and Reactivity

Incompatibilities

Incompatible with azocyclotin, and perhaps other azo compounds and organometallics.

Stability

Pyrethrins are stable for long periods in water-based aerosols where emulsifiers give neutral water systems. Pyrethrins thermally stable @ room temperature.
