7. www.jst.umn.edu Glove Usage Wear gloves of a material known to be resistant to permeation by the substances in use. Look for an expiration date on individual packages of gloves. Before use, check gloves (even new ones) for physical damage such as tears or pinholes. Check reusable gloves for previous chemical damage. Dispose of gloves when they show any sign of leakage or deterioration. Select gloves of the correct size and fitting. Some gloves, especially lightweight disposables, may be flammable: keep hands well away from flames or other high temperature heat sources. Replace gloves periodically, depending on the frequency of use and their permeation and degradation characteristics relative to the substances handled. Remove gloves before handling objects such as doorknobs, telephones, pens, and computer keyboards. When removing gloves, do so in a way that avoids skin contact with a possibly contaminated glove exterior. Always wash hands after removing gloves. Dispose of contaminated gloves properly. Do not attempt to re-use disposable gloves. 7 http://www.dehs.umn.edu/PDFs/gloves.pdf
