Get a grip on hand hazards

New-age gloves are here to help
According to Jeff Stauffer, vice president of
Stauffer Glove and Safety, Inc., “We’ve seen
the momentum of specialized work gloves
grow over the past several years. There is a
definite trend away from traditional leather and cotton
work gloves toward gloves that offer specialized protection,
better dexterity and better value.”
Stauffer’s own company, a 103-year-old
Pennsylvania enterprise that started as a manufacturer
of cotton work gloves, has witnessed the transition.
Under fourth-generation family ownership,
the company no longer manufactures cotton
gloves and is now a distributor of all kinds of
work gloves.
Today’s PPE glove market is filled with alternatives
to traditional leather and cotton work
gloves. Gloves knit of engineered yarns provide
high levels of cut resistance. Polymer-coated
cotton and nylon knit gloves now meet workforce
needs for more flexible, longer-lasting
gloves. Hi-vis colors, illuminated backs, ventilated
backs, task-specific levels of coatings and
specific sizing all work to make these gloves the
up-and-coming gloves of choice for construction
workers. Not only are these gloves more resilient
and serviceable for more applications than
traditional work gloves, they also have superior
barrier properties and longer lasting coatings.
The technology
The specifics behind this trend to new-age
gloves lie with technology.
“The technology in these new gloves provides
better protection and yield along with better
fit, lighter weight and task-specific features,”
Stauffer says. He also says that because it is
hard to change what has been accepted for years
and because there are still some construction
jobs for which leather is a viable choice, he
believes leather will remain a contender.
Some of the chemicals used in leather glove
curing may pose hazards to workers. Chromates,
which are known sensitizers and carcinogens,
have been used to cure leathers. These chemicals
are not used in polymer-coated gloves. Most
leather and cotton glove models are manufactured
on a “few sizes fit all” basis, which makes
fit a problem.
Manufacturers of polymer-coated gloves
spend millions of dollars annually researching
newer and better glove designs in sizes
ranging from extra small to extra, extra large.
Polymer coatings made from Natural Rubber
Latex (NRL) or the synthetic polymers, Nitrile,
Neoprene, PVC or Polyurethane, have come
into their own in the past few years. These
lighter-weight, ergonomic glove designs allow
workers to keep wearing gloves while performing
tasks that require more accurate feel and
finer dexterity — tasks that yesteryear’s workers
often performed “gloveless.”
In addition, today’s technology produces polymeric
gloves with length-of-wear times two to
ten times longer than those of leather and cotton
gloves. Some flat-dipped gloves
even have an extra layer of polymer
in stress areas such as the thumb
crotch between the thumb and first
finger. Polyurethane-coated nylon
or HPPE gloves offer very durable
coatings that are super lightweight
and comfortable.
Wear the right glove
Polymer coatings may be engineered to either
absorb or repel oil or to serve as a barrier to
chemicals that may irritate, burn or sensitize skin.
Protection against chemicals is particularly important
because some chemicals used on the worksite may
be absorbed into the skin and may result in long-term
chronic toxic effects from low-level exposure.
For example, caustic wet cement water can immediately
penetrate cotton and leather gloves. On the
other hand, a fully coated polymer glove offers excellent
protection from exposure to caustic cement water
and hexavalent chromium from Portland cement. This
is important because hexavalent chromium is a potent
skin sensitizer that causes dermatitis and debilitating
chemical sensitization in workers whose skin is
exposed to it.
More than 1.3 million workers in the construction
trade are exposed to Portland cement and thousands
more to cement dust. Skin conditions in the masonry
industry are 2.5 times the national average. A study
by the EPA and Johns Hopkins showed a very strong
dose-response relationship for chromate exposure
and the development of lung cancer. Another study
by Mancuso showed that 23.3 percent, or almost
one fourth, of the deaths of workers in a chromate
plant since 1951 were from lung cancer. In addition,
according to The National Safety Council’s “Injury
Facts 2010,” there were nearly 49,000 new skin diseases
or disorders for the construction industry reported
to the Bureau of Labor Statistics.
Prevent lacerations
According to The National Safety Council’s “Injury
Facts 2010,” its last survey (2007) lists for the construction
industry 12,530 injuries to the fingers, 7,490
injuries to the hand excluding fingers and 3,770 injuries
to the wrist. Gloves designed for cut resistance
and oil absorbance are an excellent choice to reduce
injuries from cuts and/or dropping parts. Protection
from lacerations along with enhanced gripping action
are a win-win. High performance fibers such as HPPE
can be made even stronger by wrapping with stainless
steel or fiberglass yarn for the highest cut resistance
available. Sponge and foam Nitrile coatings offer the
advantage of adding high durability to cut-resistant
liners that could be worn out quickly in handling concrete
blocks or bricks.
It should be noted that there is no cut-resistant
glove that works for moving or serrated blades.
With new developments in glove technology, lack
of dexterity or cumbersomeness can be a thing of the
past. Reduction of hand injuries in the construction
industry is everyone’s job. Non-leather hand protection
products are designed to enhance safety, comfort
and worker acceptance. The only missing ingredients
are training and enforcement. Workers must be
trained on the risks associated with the jobs they are
performing and given the proper PPE to help reduce
those risks. New-age gloves are here to make that
happen.
