• Important points to consider
• All chemicals will permeate protective barriers.
• No single protective material will be an
  effective barrier against all chemicals.
• Gloves and other PPEs may look similar, so care
  must be taken in choosing.
• A chemical that has been absorbed by a protective
  glove material will continue to permeate!

HAZWOPER

• Glove permeation data likely is based on
  room-temp conditions. Higher temps may likely
  increase permeation rates!
• Glove protection information based on generic
  materials. Manufacturers should be consulted.
• Increasing thickness normally will increase the
  time to breakthrough, but benefit may be offset
  by decrease in flexibility and tactility.
• If glove protection is critical to health,
  material should be tested against chemicals to be
  used!

• In the OSHA Standard for Air Contaminants (29 CFR
  1910 Subpart Z), in Table Z-1-A (Limits for Air
  Contaminants), there is a column for Skin
  Designation. The standard states

HAZWOPER

• To prevent or reduce skin absorption, an
  employees skin exposure to substances listed in
  Table Z-1-A with an X in one or both of the
  Skin Designation columns following the substance
  name shall be prevented or reduced to the extent
  necessary in the circumstances through the use of
  gloves, coveralls, goggles, or other appropriate
  personal protective equipment, engineering
  controls or work practices.
• A small subset of these chemicals include
• Acrylamide Isopropyl alcohol
• Benzene Methyl alcohol
• n-butyl alcohol Phenol
• Carbon disulfide Toluene

• Sometimes even the obvious needs stating!
• Gloves will not provide protection against
  chemical exposure if
• they have holes caused by punctures, cuts or
  abrasions.
• (Additional, heavier-duty gloves may be needed.)
• Gloves will not provide suitable protection
  against a chemical
• exposure if the gloves are degraded by exposure
  to the chemical, or they are permeated by the
  chemical in a significant amount. (Note that
  some chemicals can permeate rapidly through
  materials which will resist degradation, and the
  user can be exposed unexpectedly.)
