Safety Gloves ByungJoon Lim 10/16/2012
Safety Gloves • Protect your hands from hazardous chemicals • “Gloves MUST BEworn whenever handling hazardous chemicals. Appropriate gloves MUST BE provided for all laboratory employees.” – From EHS lab safety manual • Glove compatibility charts are useful to choose proper gloves.
Latex • Mostly produced from natural rubber tree • Excellent protection from aqueous solution, but weak protection from various organic chemicals • Some people are allergic to latex.
Nitrile • Most widely used in organic labs • Synthetic rubber copolymer of acrylonitrile and butadiene • Very resistant to aliphatic hydrocarbons, but permeable to aromatic hydrocarbons or ketones
Neoprene • Synthetic rubber polymer registered by DuPont • Monomer is chloroprene. • Similar or Better protection effect against most chemical than nitrile • But more expensive!
Other polymers • Butyl – isobutylene and isoprene • Polyvinyl chloride (PVC) – vinyl chloride • Viton - hexafluoropropyleneand vinylidene Fluoride • Ethylene vinyl alcohol (EVOH) – ethylene and vinylalcohol • Working very well but very expensive! • Hardly used as disposable gloves in labs
Cautious! • “ANYglove can be permeated by chemicals.” – From EHS lab safety manual • Don’t believe gloves too much - Replace used gloves regularly! • Put on two folds of gloves (latex & nitrile) • More information for individual solvent or chemical • http://www.showabestglove.com/site/ • http://www.mapaglove.com/index.cfm
