First Aid Measures
Ingestion
There is no specific antidote for pyrethrin poisoning. Treatment is symptomatic and supportive and includes monitoring for the development of hypersensitivity reactions with respiratory distress. Provide adequate airway management when needed. Gastric decontamination is usually not required unless the pyrethrin product is combined with a hydrocarbon. Allergic reaction: mild: antihistamines with or without epinephrine. Severe: oxygen, aggressive airway management, antihistamines, epinephrine (adult: 0.3 To 0.5 Ml of a 1:1000 solution subcutaneously; child: 0.01 Ml/kg; may repeat in 20 to 30 min), corticosteroids, ecg monitoring, and iv fluids.

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 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.

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. Employees should be provided with and be required to use impervious clothing, gloves, and face shields (eight-inch minimum). Wear appropriate equipment to prevent: repeated or prolonged skin contact. Wear eye protection to prevent: reasonable probability of eye contact.

Accidental Release Measures
Small spills/leaks
Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Water spill: Use natural deep water pockets, excavated lagoons, or sand bag barriers to trap material at bottom. If dissolved, in region of 10 ppm or greater concentration, apply activated carbon at ten times the spilled amount. Remove trapped material with suction hoses. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.

Stability and Reactivity
Stability
More stable towards UV light than natural pyrethrins decomposed by UV light. Hydrolyzed in alkaline media. Are stable for long periods in water-based aerosols where emulsifiers give neutral water systems.

Incompatibilities
Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products Reacts with many acids and bases liberating heat and flammable gases (e.g., H2) Reacts with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat Incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides Reacts violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4.
