Buy only what you need If you must purchase products that are hazardous, buy only what you can use completely. That way you won't have to worry about storage or disposal. If you do have leftovers, try to find someone who can use them. Do not, however, give away old pesticides. The label should tell you what equipment you need when using a specific product, but if you're not sure, ask the dealer or call the manufacturer.
Gloves help prevent chemicals from being absorbed through the skin.
Nitrile gloves, available in safety supply stores, will protect your hands against most products, except strong acids or bases. Products that contain acids or bases require the use of heavy rubber gloves. Chemical splash goggles prevent splashes and vapors from getting in the eyes. Respirators and dust masks prevent inhalation of particulates, mists, vapors and fumes. Be sure to use the right cartridge and filter for the job.
