A great deal of attention has
been focused on ergonomic design of furniture, workstations, and
other equipment to reduce the growing number of repetitive-motion
injuries. However, no one seems to be looking at ergonomics as it
applies to slip-and-fall accidents.
An opportunity is being missed. Slips and falls are one of the
biggest causes of injuries in business and industry today.
Ergonomics may be part of the solution.
Generally, ergonomics is considered the science of designing
workplaces (or other areas) so as to encourage the most economic
expenditure of human effort. In modern usage, however, the term
has often been applied to problems in the workplace that emerge
as injuries affecting the performance of people's jobs. Injuries
caused by repetitive motion, such as carpal tunnel syndrome, are
classic examples. The response has been to redesign the workplace
in some way to reduce or eliminate the likelihood of such
injuries, and we are now surrounded by "ergonomic"
chairs, desks, workstations, and computer keyboards.
A far more costly threat to productivity is the everyday
slip-and-fall accident. For each of the last several years,
according to the Bureau of Labor Statistics, slip-and-fall
accidents have accounted for about 10 percent of all the
non-fatal workplace injuries in the U.S. Many of these injuries
are much more serious than carpal tunnel syndrome, involving head
and back injuries that require lengthy recovery.
The National Safety Council reports that the average cost of a
"disabling" injury-meaning one that causes time lost
from work, even for one day-topped $27,000 in 1993.
A slip-and-fall accident involves many "hidden" cost,
such as training a replacement for the injured worker and
overtime pay needed to catch up on lost production. This is a
tremendous burden on American businesses.
Though the benefits of ergonomic changes in the workplace are
hard to pin down in terms of real savings, reducing slip-and-fall
accidents can have an immediate and highly visible "return
on investment" because of such accidents' high cost.
Slip-and Fall Threats Abound
One factor in these accidents is the amazing number of
opportunities for slips. They are present even in companies with
the best housekeeping. Think of the possibilities: wetness near
doors and loading docks, condensation from chemical storage
tanks, grease, and oils from production or from maintaining
vehicles and machinery, cleaning substances, spills of fluids
used in production, metal stairs on a humid day. And those are
just the indoor hazards.
One of the critical factors is the need for workers to cross or
work on public areas where the employer has no control over the
surface.
For example, firms scrape and salt their own drives in winter to
protect people, but they have no control over the footing under
the worker repairing a machine in the field or crossing a public
street to his or her car.
A third factor, often overlooked, is fatigue. Many workers must
stand or sit in the same place for hours each day. That takes an
unseen toll on the feet and legs.
Slip-and-fall accidents have accounted for about 10 percent of
all the non-fatal workplace injuries in the U.S. for each of the
last several years.
Finally, many workers don't acknowledge these risks, or they
minimize the danger. The result is thousands of slip-and-fall
accidents each year that could have been prevented and millions
of dollars in lost profits.
Applying Ergonomics to Slips and Falls
How do you apply an ergonomic solution to slips and falls? The
goal is to work toward the most economical effort for the worker,
thus helping cut accident costs. There are three basic steps:
1. Analyze and change the
environment.
2. Analyze and change the equipment your people work with.
3. Change your workers' minds.
This is the same process you use
in redesigning a work center to eliminate sore backs. In the case
of slips and falls, changing the workers' environment really
means studying the floors they walk on. Floors can be changed to
a degree to prevent slips. Especially greasy areas can be
roughened by applying coatings, friction decals, or a rougher
surface. Traffic patterns can be analyzed and changed. Obvious
hazards such as leaks can be corrected. Signs, high-visibility
paint, and color-coding can call attention to dangerous areas.
Housekeeping can always be improved.
The next step is to change the equipment the workers use. That
suggests the obvious: If you can't change every low friction
surface, try to put better traction on the shoes the workers wear
on those surfaces. High-traction footwear is a flexible solution
to the problem of slips and falls. Then workers take their
accident prevention with them wherever they go. It's
cost-effective, and it works.
High-traction footwear means more than rubber boots for all
workers. Standard rubber boots will help on dry surfaces, but
they can be more slippery than regular shoes when the going gets
wet. Manufacturers have put a fair amount of technology into true
high-traction footwear, and it pays to study your options.
One example is a boot in which traction is provided by aluminum
oxide grit embedded in the soles. The grit is in strips that are
angled-instead of running straight across the sole-for better
grip. This angled design mimics the metatarsal bones of the foot
to maximize surface contact.
Another key element of the design is a series of grooves between
the angled strips of grit. These grooves use the natural walking
motion of the foot. This is important because no matter how good
a safety product is, workers will not use it if it is difficult
or inconvenient for them. Good high-traction footwear will have
features like extra-wide openings to accommodate thick boots and
special smooth areas inside the heel to help the workers put them
on and remove them easily.
How about fatigue? Again, the ergonomic approaches are to try to
change the environment and to change the equipment. Some
companies install mats to improve the underfoot environment and
ease the load on machine operators' feet. Many footwear makers
offer cushioned insoles that fit any work shoe or boot and help
prevent fatigue in feet, ankles, knees, and backs.
Training Can Help
Safety training gets less attention than it should at many
companies, partly because managers don't always know how to
conduct safety training effectively. Most suppliers of safety
equipment are more than happy to assist in training.
Whether or not OSHA regulations on ergonomics are ever
implemented, the ergonomic approach to workplace problems seems
sure to spread. It has already reached into many areas where no
one ever expected ergonomics to go. Look for this trend to
continue.
