Transcript Glove

Glove Selection
Breakthrough Time time after application on the exterior that it takes to
detect a chemical on the interior of a glove
Permeation Rate rate at which a chemical moves through the material
(units: mcg/cm2/min)
Degradation reduction in one or more of the physical properties
of a glove material due to contact with a chemical
Chemical Combinationschoose 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
Latex
• good for biological and aqueous materials
• low chemical protection
• can cause latex allergies
Nitrile
•good for solvents, oils, greases, and some acids and bases
•use thicker, reusable gloves for extended contact
Butyl Rubber
•good for ketones and esters
•bad for aliphatic, aromatic, and halogenated hydrocarbons
Neoprene
• good for acids, bases, alcohols, peroxides,
hydrocarbons, and phenols
• bad for halogenated and aromatic hydrocarbons
• good for most hazardous chemicals
Silver Liner
• improve the low dexterity by wearing
heavier weight nitrile gloves on top
(aka Norfoil)
Viton
•good for chlorinated and aromatic solvents
•bad for ketones
•resistant to cuts and abrasions
PVC
•good for acids, bases, oils, fats, peroxides, and amines
•bad for most organic solvents
•resistant to cuts and abrasions
PVA
• good for chlorinated and aromatic solvents
• bad for aqueous solutions
Including Details of Evaluation Criteria:
• Breakthrough Time
• Permeation Rate
• Degradation
