Glove Selection

Chemical Compatibility

Evaluation Criteria

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/cm2/min)

Permeation Rate -

Degradation -

reduction in one or more of the physical properties of a glove material due to contact with a chemical

Additional Criteria

Chemical Combinations-

choose the glove material based on the compound with the shortest breakthrough time

and based onPotential Effects of Skin Exposure

as well asDecontamination Proceduresif gloves are compromised

Glove Types

•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

Neoprene

• good for biological and aqueous materials• low chemical protection• can cause latex allergies

Latex

Glove Types (cont’d)

• 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

PVA
