| First Aid Measures | Back to Contents | 【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 | Back to Contents | 【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 | Back to Contents | 【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. | 【Eyes】
A stuffy, runny nose and scratchy throat following inhalational exposure may be noted. | 【Hazards】
Containers may explode when heated. Runoff may pollute waterways. | 【UN (DOT)】

| Exposure Controls/Personal Protection | Back to Contents | 【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 | 【Poison Class】

| Fire Fighting Measures | Back to Contents | 【Flash Point】
166 | 【Fire Fighting】
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) | 【Fire Potential】
Slight fire hazard. Combustible |
| Accidental Release Measures | Back to Contents | 【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 | Back to Contents | 【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. | 【Decomposition】
When heated to decomposition it emits acrid fumes. | 【Combustion Products】
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. |
