1. What are the potential hazards that we are trying to protect against?
There are at least 6 different hazards that we are trying to protect against.
A. Foreign Particles – This can include dust, sawdust, metal shavings or any other particle that might come in contact with the eye.
B. Chemicals – This is most commonly splash protection but might also include airborne chemicals that may irritate or harm the eyes.
C. Heat – Extreme heat can be harmful to the eyeball and even lower amounts of heat, if not treated properly, can dehydrate the eye and cause damages.
D. Light – Light can affect the eyes in much the same manner as heat with the results not showing up until hours later. Lasers and welding are especially dangerous to the eyes and can results in a permanent burning of the retina.
E. Blow or Impact – Blows, bumps and trauma to the eyeball can result from impacts to the eye socket, even when the eye is closed.
F. Cuts – Lacerations to the eyeball can come from a variety of ways. In at least one instance, a piece of paper, falling out of a cabinet, caused a “paper cut” across a women’s retina that was severe enough to require surgery.
Tomorrow we will look at When and where the hazards are present.
