Eye
injuries in the workplace are surprisingly common. Jerry Traer, of Workplace
Safety North talks us through the many options available to employers to help
safeguard their employees’ sight. While his viewpoint is formed from a pulp and
paper background, his observations are applicable to a huge variety of
industries where workers’ eyesight may be endangered by workplace hazards.
Every year in Ontario, Canada alone, 3,000
people sustain eye injuries on the job, resulting in lost time, and in some cases
vision loss, either temporary or permanent.
According to NIOSH (the National Institute for
Occupational Safety and Health), each day about 2,000 US workers have a
job-related eye injury that requires medical treatment. About one third of the
injuries are treated in hospital emergency departments and more than 100 of
these injuries result in one or more days of lost work.
There are 2.5 million eye injuries annually in
the United States alone. Out of this group, 50,000 people permanently lose part
or all of their vision1. Eye injuries are the number two leading cause of
blindness, second to cataracts. The most staggering realisation about these
statistics is that 90% of eye injuries can be prevented by wearing protective
eye equipment.
Eye
injuries cost industry billions of dollars in workers’ compensation claims,
lost work days and lost productivity. Injuries to the face, including disabling
and non-disabling eye injuries, can cost an average of $17,187 per total claim
and account for 33,010 lost work days in the United States2. On top of the cost
to industry, eye injuries have a devastating effect on the injured worker as
well as your workforce. Without any in-depth explanation needed, the trauma of
losing one’s eyesight is devastating. It also affects the morale of co-workers.
Employees who lose some or all of their eyesight may never be able to work in
the same occupation again. It will completely affect his or her life, both at
work and personally, forever. These figures are sobering given that the majority
of eye injuries are preventable.
Introduction to the eye
The eyes are wonderful sensory organs. They
help people learn about the world in which they live. Eyes see all sorts of
things - big or small, near or far, smooth or textured, colours and dimensions.
The eyes have many parts - all of which must function in order to see properly.
Inside the eye
In addition to the many sections of the
eyeball itself, muscles are attached to the outer walls of the eyeball. The eye
muscles are attached to the eyes so that we can move our eyes. If anything goes
wrong, like diabetic eye disease, an individual might not be able to see as
well.
A complete picture
Visual information from the retina travels
from the eye to the brain via the optic nerve. Because eyes see from slightly
different positions, the brain must mix the two images it receives to get a
complete picture.
What we think of as seeing is the result of a
series of events that occur between the eye, the brain, and the outside world.
Light reflected from an object passes through the cornea of the eye, moves
through the lens which focuses it, and then reaches the retina at the very back
where it meets with a thin layer of colour-sensitive cells called the rods and
cones.
Because the light criss-crosses while going
through the cornea, the retina ‘sees’ the image upside down. The brain then
‘reads’ the image right-side up.
Glossary
• Aqueous Humour: a clear, watery fluid that
fills the front part of the eye between the cornea, lens and iris
• Choroid: the middle layer of the eyeball
which contains veins and arteries that furnish nourishment to the eye,
especially the retina
• Conjunctiva: a mucous membrane that lines
the eyelids and covers the front part of the eyeball
• Cornea: the transparent outer portion of the
eyeball that transmits light to the retina
• Fovea: A tiny spot located in the macula
that is the area of clearest vision on the retina
• Iris: the coloured, circular part of the eye
in front of the lens. It controls the size of the pupil
• Lens: the transparent disc in the middle of
the eye behind the pupil that brings rays of light into focus on the retina
• Macula: is a small area of the retina
located near the optic nerve at the back of the eye. It is responsible for our
central, most acute vision
• Optic Nerve: the important nerve that
carries messages from the retina to the brain
• Pupil: the circular opening at the centre of
the iris that controls the amount of light into the eye
• Retina: the inner layer of the eye
containing light-sensitive cells that connect with the brain through the optic
nerve. It also contains retinal blood vessels which feed the retina and which
can be affected by diabetes
• Sclera: the white part of the eye that is a
tough coating which, along with the cornea, forms the external protective coat
of the eye
• Vitreous Body: a colourless mass of soft,
gelatin-like material that fills the eyeball behind the lens
Causes of eye injuries at work
Common causes for workplace eye injuries
include:
• Flying objects, such as bits of metal,
glass, stone or wood
• Unsafe handling of tools
• Chemical splashes
• Radiation
• Sparks and slag from welding and cutting
• Pipes and wires sticking out of walls
• Objects hanging from ceilings
What you can do: protect your eyes
Luckily, there are things you can do to
decrease these dangers on the job. First and foremost is the identification of
areas where flying parts or debris are a common occurrence.
In
these areas, engineering controls, where appropriate, should be used to limit
the objects’ movements. Shields and vacuum devices will help lessen the chance
of objects in the air.
Once engineering controls are exhausted, then
the next step would be the use of personal protective equipment (PPE). Choose
protective eyewear that is designed for the specific duty or hazard, and make
sure it fits and is worn consistently. Protective eyewear used in Canada must
meet Canadian Standards Association (CSA) standards.
The European Union and associated countries
also have comprehensive legislation regarding the performance requirements and
use of PPE, and this covers all forms of safety eyewear. It is a requirement
that safety eyewear must be assessed and CE marked before it can be supplied
into the European market. It has now been illegal for many years to place an
item of PPE on the market in a European Member State unless it carries the CE mark.
Know your rights and responsibilities
Workers have the right to:
• Know about hazards in the workplace
• Participate in keeping the workplace safe
• Refuse unsafe work
Workers’ responsibilities include:
• Always practice safe work procedures
• Report unsafe conditions to your supervisor
or employer
• Properly wear any protective equipment the
job requires
• Do not do anything on the job that will
endanger yourself or others
Employers must:
• Take every reasonable precaution to protect
a worker’s health and safety
• Make sure necessary safety equipment is
provided, used properly and maintained
• Inform workers and supervisors of any
hazards and how to handle them
• Ensure that procedures are followed in the
workplace
• Provide information, instruction and
competent supervision to protect the health and safety of workers
Supervisors must:
• Take every reasonable precaution to protect
a worker’s health and safety
• Inform workers of job hazards and ensure
they are trained to do their jobs safely
• Ensure that workers work safely and use the
equipment and protective devices properly where required
Causes of eye injuries
• Flying objects, such as bits of metal,
glass, stone or wood
• Unsafe handling of tools
• Chemical splashes
• Pipes and wires out of walls
• Objects hanging from the ceiling
Responsibilities
• Workers - always practice safe work
procedures; report unsafe conditions; wear proper protective equipment
• Supervisors - take every precaution
reasonable; inform workers of eye injury hazards; ensure workers work safely
• Employers - take every precaution
reasonable; make equipment safe, ensure it is used properly and well
maintained; inform workers and supervisors of eye injury hazards in the
workplace; ensure proper procedures are followed; provide information and instruction,
so that jobs are done safely
Controlling eye hazards
• Engineering controls: shields, barriers and
guards for high velocity flying objects; vacuums and exhaust systems for
lighter particles
• Personal Protective Equipment (PPE): safety
glasses (prescription/non-prescription); goggles/face shields; full face
respirators
Excuses for not wearing PPE
• I’m in a hurry (“It will only take a few
seconds”)
• I left them at my work station
• They distort my vision
• They’re uncomfortable, hot and they fog up
• I’ve worked here 25 years without an injury,
I don’t need them
• I look like a geek when I wear them
All the excuses in the world won’t, however,
stand up to the power of the image on page 58. Protect yourself - don’t let
this happen to you!
