| [Fire Fighting] Use carbon dioxide, foam, or dry chemical on fires involving pyrethroids. | |
| [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. | |
| [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. | |
| [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. | |
| [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. | |
| [Respirators] Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive pressure mode. Any supplied-air respirator with a full face piece and operated in pressure-demand or other positive pressure mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive pressure mode. | |
| [Exposure Effects] The toxological properties of this substance have not been fully investigated. | |

| [EC Index Number] 607-239-00-5 | |
| [EC Class] Very toxic; Toxic; Harmful; Dangerous for the Environment | |
| [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] Decomposed in alkaline solutions. Exposure to light and air leads to oxidation and loss of activity. 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 Incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions Incompatible with other oxidizing agents such as peroxides and epoxides Can react vigorously with reducing agents. |
