1. Glove Selection

2. Breakthrough Time - time after application on the exterior that it takes to detect a chemical on the interior of a glove rate at which a chemical moves through the material (units: mcg/cm 2 /min) Permeation Rate - Degradation - reduction in one or more of the physical properties of a glove material due to contact with a chemical

3. Chemical Combinations- choose the glove material based on the compound with the shortest breakthrough time and based on Potential Effects of Skin Exposure as well as Decontamination Procedures if gloves are compromised

4. good for solvents, oils, greases, and some acids and bases use thicker, reusable gloves for extended contact Nitrile Butyl Rubber good for ketones and esters bad for aliphatic, aromatic, and halogenated hydrocarbons good for acids, bases, alcohols, peroxides, hydrocarbons, and phenols bad for halogenated and aromatic hydrocarbons good for acids, bases, alcohols, peroxides, hydrocarbons, and phenols bad for halogenated and aromatic hydrocarbons Neoprene good for biological and aqueous materials low chemical protection can cause latex allergies Latex

5. good for most hazardous chemicals improve the low dexterity by wearing heavier weight nitrile gloves on top Silver Liner (aka Norfoil) good for chlorinated and aromatic solvents bad for ketones resistant to cuts and abrasions Viton PVC good for acids, bases, oils, fats, peroxides, and amines bad for most organic solvents resistant to cuts and abrasions good for chlorinated and aromatic solvents bad for aqueous solutions good for chlorinated and aromatic solvents bad for aqueous solutions PVA
