Hazards and Protection.
Storage
Ventilate well. Store in closed drum in cool, dry place. 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.
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.
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
No data.
Incompatibilities
Incompatible with alkaline materials. Incompatible with lime and ordinary soaps because acids and alkalies speed up processes of hydrolysis.
Decomposition
When heated to decomposition it emits acrid smoke and fumes.

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

Exposure effects
   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.
