There
seems are no safety shoes which can provide protection for all hazards like
electric shocks, slippery, chemical hazard and etc… All footwear manufactured
to ANSI specifications will be marked with the specific portion of the standard
with which it complies.
Customs
who want buy cheap safety shoes should match
safety footwear to a specific environment or hazard, other factors include
traction, chemical exposure, cold and heat. Burns resulting from chemical and
molten metal splashes or other flammable and explosive materials are frequent
in the mining and manufacture of heavy metals and the production of chemicals.
The following I’ll take a introduction for chemical-resistant footwear.
Chemical-resistant
footwear
as the name implies should be worn in areas with potential chemical or
corrosive splashes. Unfortunately, there are more chemical compounds than types
of shoes, and matching footwear material to a chemical hazard can be a
challenge.
Generally,
there are three types of chemical-resistant footwear material: rubber, neoprene
or PVC. Seek a chemical resistance comparison guide to find out which one is
best for a chemical.
1.
Rubber is suitable for some chemical environments and is rated excellent for
many acids and ammonias.
2.
Neoprene, lighter in weight than rubber, is rated excellent for most acids,
oils, petroleum and many other chemicals. This compound can be used in
environments where rubber will not work: meat and poultry processing,
petrochemical, agrichemical, oil drilling and refining, dairy and food
processing, fishing, breweries and bottling, farming and waste disposal.
"Blood
and animal fats are serious enemies to rubber and would deteriorate the boot
very quickly. Neoprene has tremendous resistance to attack by blood and animal
fats and also has tremendous resistance properties to petroleum and
petrochemical products."
3.
PVC is rated excellent for some acids and some oils. Its compounding is
relatively convenient in determining blends to resist specific chemicals.
PVC
products range from general industrial applications with no serious chemicals,
to moderate blends to resist chemicals in poultry or animal waste environments,
to serious compounds for hazmat technicians, site remediation and emergency
responders. The latter meets the National Fire Protection Association (NFPA)
1991 chemical permeation-resistant and flame-resistant requirements. It is
permeation tested to resist NFPA 1991's list of 21 challenge chemicals.
While
we should do not rely on matching footwear material to a chemical hazard solely,
the best way to make sure a particular material will work in a specific
chemical environment is to have the high quality working
shoes tested.
