Some manufacturers use a combination of materials to produce
heavy-duty gloves which provide even greater user protection.
Some of the common natural materials
used include variations of deerskin and cowhide leather and, for
additional insulation, lining material, such as sheepskin. A durable
material, leather gloves excellent gripping characteristics, as well as
resist moderate heat, sparking, and cuts from sharp or abrasive materials.
Gloves produced from a combination
of natural and synthetic rubbers and leather material are effective in
preventing shock and burns from electrical contact. Specifically, these
rubber gloves may contain leather protectors and cuffs and be lined with
insulating wool and thermal materials. These electrical gloves are
typically OSHA-compliant and are considered either ozone resistant or
non-ozone resistant. Both variants should be electrically tested before
use and regularly after use. Some of the typical applications and
processes that require these gloves include plant and facility procedures,
and power utility maintenance.
