Hazardous Substances Data: 82657-04-3(Hazardous Substances Data)

Skin, Eye, and Respiratory Irritations
Immediately irritating to the eye. /Pyrethrins/
The chief effect from exposure ... is skin rash particularly on moist areas of the skin. ... May irritate the eyes.
UN 2588
Fire Fighting Procedures
Use carbon dioxide, foam, or dry chemical /on fires involving pyrethroids/. /Pyrethrum/
Fire-fighting: Self-contained breathing apparatus with a full facepiece operated in pressure-demand or other positive-pressure mode. /Pyrethrum/
USEPA/OPP Pesticide Code 128825; Trade Names: FMC 54800, Capture, FMC 54800 technical, Talstar, Brigade, Biflex.
Emulsifiable concentrate; suspension concentrate; wettable powder; ultra-low volume liquid; granule.
Material contains greater than/equal to 97% cis-isomer and less than/equal to 3% trans-isomer.
Reactivities and Incompatibilities
Incompatibility: Strong oxidizers. /Pyrethrins/
... Incompatible with lime & ordinary soaps because acids & alkalies speed up processes of hydrolysis. /Pyrethrins/
Other Preventative Measures
Skin that becomes contaminated with /pyrethrum/ should be promptly washed or showered with soap or mild detergent and water. /Pyrethrum/
Clothing contaminated with /pyrethrum/ should be placed in closed containers for storage until provision is made for the removal of /pyrethrum/ from the clothing. /Pyrethrum/
Respirators may be used when engineering and work practice controls are not technically feasible, when such controls are in the process of being installed, or when they fail or need to be supplemented. Respirators may also be used for operations which require entry into tanks or closed vessels, and in emergency situations. /Pyrethrum/
Employees who handle /pyrethrum/ ... should wash their hands thoroughly with soap or mild detergent and water before eating, smoking, or using toilet facilities. /Pyrethrum/
Avoid contact with skin. Keep out of any body of water. Do not contaminate water by cleaning of equipment or disposal of waste. Do not reuse empty container. Destroy it by perforating or crushing. /Pyrethrum/
Workers should wash: Promptly when skin becomes contaminated. /Pyrethrins/
Work clothing should be changed daily: If it is reasonably probable that the clothing may be contaminated. /Pyrethrins/
Remove clothing: Promptly if it is non-impervious clothing that becomes contaminated. /Pyrethrins/
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
Protective Equipment and Clothing
Employees should be provided with and required to use dust- and splash-proof safety goggles where /pyrethroids/ ... may contact the eyes. /Pyrethroids/
Employees should be provided with and be required to use impervious clothing, gloves, and face shields (eight-inch minimum). /Pyrethroids/
Wear appropriate equipment to prevent: Repeated or prolonged skin contact. /Pyrethrum and pyrethrins/
Wear eye protection to prevent: Reasonable probability of eye contact. /Pyrethrins/
