Chemical Permeation Data
Before using a garment in a chemical situation, consult the chemical permeation
data appropriate to the garment material. This information is to be used as a
guide only. The permeation performance of any material depends on a number
of factors including chemical concentration, temperature, time and amount of
exposure, etc. Due to the large number of variables, it is impossible for all garment
materials to be tested against all chemicals, all combinations or mixtures, and all
temperatures at which the chemical might be encountered.
Chemical permeation tests are performed under laboratory conditions – not
actual workplace conditions. They address chemical breakthrough characteristics
and do not account for physical performance characteristics that affect barrier
such as abrasion, flex fatigue, puncture, tear, oxidative degradation, or degraded
performance due to previous contamination.
No single protective material will protect against all chemicals for all situations.
The best course of action is to test the primary garment materials against the
specific chemical hazard, at the temperature and in the concentrations to be
encountered. Kappler, Inc. will provide free swatches of primary garment materials
for testingand help arrange to have these tests performed.
Static Electricity
Under certain conditions, such as cold and dry weather, it is possible for garments
to build and discharge static electricity. Discharges are not normally dangerous
except in situations where generation of an electrical spark could ignite a flamma-
ble atmosphere. When working around flammable chemicals, steps to eliminate
potential static discharges should be used. In these situations, recommended
precautionary steps include raising humidity level of the work area and/or using
a commercial, anti-static application.
