OFFICE
SAFETY
General
Office Safety
A large percentage of workplace accidents
and injuries occur in office buildings. Like the shop or laboratory the
office requires a few preventive measures to ensure a safe and healthful
environment. Common causes of office accidents include the following:
-
Slipping, tripping, and falling hazards
-
Burning, cutting, and pinching hazards
-
Improper lifting and handling techniques
-
Unobservant and inattentive employees
-
Improper office layout and arrangement
-
Dangerous electrical wiring
-
Exposure to toxic substances
-
Horseplay
The following sections address several office
safety practices. Other preventive measures not mentioned here may be necessary
also.
REMEMBER:
The office building is not a sterile
working environment; common workplace hazards can be extra dangerous when
you ignore them.
Refer to other chapters in this manual, such
as Electrical Safety, General Safety, Fire Safety, and others for more
information on workplace safety. Always use common sense when safety is
a concern.
Good
Housekeeping Practices
Many office accidents are caused by poor housekeeping
practices. By keeping the office floor both neat and clean, you can eliminate
most slipping, tripping, and falling hazards. Other good housekeeping practices
include the following:
-
Ensure that office lighting is adequate and
available. Replace burned out light bulbs, and have additional lighting
installed, as necessary.
-
Ensure that electrical cords and phone cords
do not cross walkways or otherwise pose a tripping hazard. If you cannot
move a cord, have a new outlet installed or secure the cord to the floor
with cord covering strips. Do not tape cords down or run them underneath
carpet.
-
Report or repair tripping hazards such as
defective tiles, boards, or carpet immediately.
-
Clean spills and pick up fallen debris immediately.
Even a loose pencil or paper clip could cause a serious falling injury.
-
Keep office equipment, facilities, and machines
in good condition.
-
Store items in an approved storage space.
Take care to not stack boxes too high or too tight. Ensure that boxes are
clearly labeled with their contents.
Hazardous
Objects and Materials
Hazardous objects such as knives and firearms
are not permitted in the workplace. In addition, hazardous chemicals and
materials should not be stored in the general office. Hazardous materials
include, but are not limited to, the following:
-
Carcinogens
-
Combustibles
-
Flammables
-
Gas cylinders
-
Irritants
-
Oxidizers
-
Reactives
Preventing
Cuts and Punctures
Cuts and punctures happen when people use
everyday office supplies without exercising care. Follow these guidelines
to help reduce the chance for cuts and punctures:
-
When sealing envelopes, use a liquid dispenser,
not your tongue.
-
Be careful when using kitchen knives, scissors,
staplers, letter openers, and box openers. Any of these items could cause
a painful injury.
-
Avoid picking up broken glass with your bare
hands. Wear gloves and use a broom and a dust pan.
-
Place used blades or broken glass in a rigid
container, such as a box, before disposing in a wastebasket.
Preventing
Machine Accidents
Only use machines that you know how to operate.
Never attempt to operate an unfamiliar machine without reading the machine
instructions or receiving directions from a qualified employee. In addition,
follow these guidelines to ensure machine safety:
-
Secure machines that tend to move during operation.
-
Do not place machines near the edge of a table
or desk.
-
Ensure that machines with moving parts are
guarded to prevent accidents. Do not remove these guards.
-
Unplug defective machines and have them repaired
immediately.
-
Do not use any machine that smokes, sparks,
shocks, or appears defective in any way.
-
Close hand-operated paper cutters after each
use and activate the guard.
-
Take care when working with copy machines.
If you have to open the machine for maintenance, repair, or troubleshooting,
remember that some parts may be hot. Always follow the manufacturer's instructions
for troubleshooting.
-
Unplug paper shredders before conducting maintenance,
repair, or troubleshooting.
Some items can be very dangerous when worn
around machinery with moving parts. Avoid wearing the following items around
machines with unguarded moving parts:
-
Loose belts
-
Jewelry
-
Long, loose hair
-
Long, loose sleeves or pants
-
Scarves
-
Ties
Preventing
Slips and Falls
As outlined in the General Safety chapter
of this manual, the easiest way to avoid slips and falls is to pay attention
to your surroundings and to avoid running or rushing. To ensure safety
for others in the office, however, follow these guidelines:
-
Arrange office furnishings in a manner that
provides unobstructed areas for movement.
-
Keep stairs, steps, flooring, and carpeting
well maintained.
-
Ensure that glass doors have some type of
marking to keep people from walking through them.
-
Clearly mark any difference in floor level
that could cause an accident.
-
Secure throw rugs and mats to prevent slipping
hazards.
-
Do not place wastebaskets or other objects
in walkways.
Preventing
Stress
To reduce stress and prevent fatigue, it is
important to take mini-breaks (not many breaks) throughout the day. If
possible, change tasks at least once every two hours. Stretch your arms,
neck, and legs often if you do the same type of work for long periods of
time. Rest your eyes often by closing them or looking at something other
then the work at hand. For a quick pick-me-up, breathe deeply several times
by inhaling through your nose and exhaling through your mouth. In addition,
always try to eat your lunch somewhere other than your desk.
Other examples of stress-relieving exercises that
can be done at your desk include the following:
-
Head and Neck Stretch:
-
Slowly turn your head to the left, and hold it for
three seconds. Slowly turn your head to the right, and hold it for three
seconds. Drop your chin gently toward your chest, and then tilt it back
as far as you can. Repeat these steps five to ten times.
-
-
Shoulder Roll:
-
Roll your shoulders forward and then backward using
a circular motion.
-
-
Upper Back Stretch:
-
Grasp one arm below the elbow and pull gently towards
the other shoulder. Hold this position for five seconds and then repeat
with the other arm.
-
-
Wrist Wave:
-
With your arms extended in front of you, raise and
lower your hands several times.
-
-
Finger Stretch:
-
Make fists with your hands and hold tight for one
second, then spread your fingers wide for five seconds.
Equipment
Safety
As mentioned earlier, common office machines, such
as the following, require special safety consideration: copiers, microwaves,
adding machines, typewriters, and computers. Be sure you know how to operate
these machines before using them, and never use one of these machines if
you think it is defective.
Other office equipment that requires safety consideration
includes furniture such as file cabinets and shelves, desks, and chairs.
File
Cabinets and Shelves
Because file cabinets and shelves tend to
support heavy loads, treat them with special care.
Follow these safety guidelines for file
cabinets:
-
Secure file cabinets that are not weighted
at the bottom. Either bolt them to the floor or to the wall.
-
Ensure that file cabinet drawers cannot easily
be pulled clear of the cabinet.
-
Do not block ventilation grates with file
cabinets.
-
Open only one drawer at a time to keep the
cabinet from toppling.
-
Close drawers when they are not in use.
-
Do not place heavy objects on top of cabinets.
Be aware that anything on top of a cabinet may fall off if a drawer is
opened suddenly.
-
Close drawers slowly using the handle to avoid
pinched fingers.
-
Keep the bottom drawer full. This will help
stabilize the entire cabinet.
In addition, follow these safety guidelines
for office shelves:
-
Secure shelves by bolting them to the floor
or wall.
-
Place heavy objects on the bottom shelves.
This will keep the entire structure more stable.
-
Ensure that there is at least 18 inches between
the top shelf items and the ceiling. This space will allow ceiling sprinklers
(if present) to function properly if a fire occurs.
-
Do not block ventilation grates with shelves.
-
Never climb on shelves (even lower shelves).
Use an approved ladder.
Desks
Follow these safety guidelines for office desks:
-
Keep desks in good condition (i.e., free from sharp
edges, nails, etc.).
-
Ensure that desks do not block exits or passageways.
-
Ensure that glass-top desks do not have sharp edges.
-
Ensure that desks with spring-loaded tables function
properly. The table should not spring forth with enough force to cause
an injury.
-
Do not climb on desks. Use an approved ladder.
-
Keep desk drawers closed when not in use.
-
Repair or report any desk damage that could be hazardous.
Chairs
Safety guidelines for office chairs include the following:
-
Do not lean back in office chairs, particularly swivel
chairs with rollers.
-
Do not climb on any office chair. Use an approved
ladder.
-
Office desk chairs should have adjustable back supports
and seat height. Make sure that your chair's back support position and
seat height are comfortable.
-
Take care when sitting in a chair with rollers. Make
sure it does not roll out from under you when you sit down.
-
Repair or report any chair damage that could be hazardous.
-
Do not roll chairs over electrical cords.
Ladders
Always use an approved ladder or stool to
reach any item above your extended arm height. Never use a makeshift device,
such as a desktop, file cabinet, bookshelf, or box, as a substitute for
a ladder.
Follow these guidelines when using ladders:
-
Do not load a ladder above its intended weight
capacity.
-
Place ladders on slip-free surfaces even if
they have slip-resistant feet. Secure the ladder if a slip-free surface
is not available.
-
Avoid placing ladders in walkways. Secure
a ladder if its location could cause an accident.
-
Keep areas around ladders clean and free of
debris. Do not use a ladder in front of a door unless the door is locked
and barricaded.
Refer to the Shop Safety chapter in this manual
for more information on ladder safety.
Work
Station Arrangement
With the extensive use of computers and other
automated desk devices in the workplace, employees must take special care
to ensure proper work station arrangement. For the purpose of this manual,
a work station consists of the equipment and furniture associated with
a typical desk job (i.e., desk, chair, and computer components).
In recent years, computer screens or Video
Display Terminals (VDTs) have received much attention concerning nonionizing
radiation levels. Tests prove, however, that VDTs do not emit harmful levels
of radiation. Improper work station arrangement combined with repetitive
motion, however, may contribute to visual and musculoskeletal fatigue.
Cumulative trauma disorders, such as carpal
tunnel syndrome may result from the stress of repetitive motion. Therefore,
it is very important to arrange your work station properly and to take
breaks frequently.
The following sections offer recommendations
for ensuring employee comfort through proper work station arrangement.
Operator's
Position
Your seating position at work is important
to your comfort and safety. To reduce the painful effects of repetitive
motion, follow these guidelines when working with computers or typewriters:
-
Always sit up straight. Make sure your chair
is adjusted to provide adequate support to your back.
-
Place your feet flat on the floor or on a
footrest. Lower legs should be approximately vertical, and thighs should
be approximately horizontal. The majority of your weight should be on the
buttocks.
-
Ensure that there is at least 1 inch of clearance
between the top of your thighs and the bottom of the desk or table.
-
Keep your wrists in a natural position. They
should not rest on the edge of the desk.
-
Keep the front edge of your chair approximately
4 inches behind your knees.
Equipment
Arrangement
By properly arranging your equipment, you can also
help reduce the harmful effects of repetitive motion. Follow these guidelines
for arranging office equipment:
§ Lighting:
Lighting around computer work stations should
illuminate the work area without obscuring the VDT or causing glare. Position
computer screens, draperies, blinds, and pictures to reduce glare during
work hours (e.g., place the VDT screen at a right angle to the window).
§ VDT Screen:
VDT images should be clear and well-defined. Adjust
the screen's brightness, contrast and display size to meet your needs.
If a screen flickers or jumps, have it repaired or replaced.
Place the VDT 20-28 inches away from your face.
The center of the VDT should be approximately 15 to 25 degrees below your
line of vision.
§ Keyboard:
Position computer keyboards so that the angle
between the forearm and upperarm is between 80 and 120 degrees. Place the
keyboard in an area that is accessible and comfortable.
§ Wrist
Support:
Use wrist supports made of a padded material.
The support should allow you to type without bending your wrists.
§ Document
Holders:
Keep documents at approximately the same height
and distance from your face as the VDT screen.
§ Telephones:
Neck tension is a common problem caused by holding
the telephone between the head and neck. Use a headset or speakerphone
if you use the telephone for extended periods of time.
