1. Precautions
WARNING: Never look directly into the end of a ber that may be carrying laser light. Laser
light can be invisible and can damage your eyes. Viewing it directly does not cause pain. The iris
of the eye will not close involuntarily as when viewing a bright light. Consequently, serious damage
to the retina of the eye is possible. Should accidental eye exposure to laser light be suspected,
arrange for an eye examination immediately.
WARNING: DO NOT use magniers in the presence of laser radiation. Diffused laser light can
cause eye damage if focused with optical instruments. Should accidental eye exposure to laser
light be suspected, arrange for an eye examination immediately.
CAUTION: Recommend the use of safety glasses (spectacles) conforming to ANSI Z87, for eye
protection from accidental injury when handling chemicals, cables, or working with ber. Pieces of
glass ber are very sharp and have the potential to damage the eye.
CAUTION: The wearing of cut-resistant safety gloves to protect your hands from accidental injury
when using sharp-bladed tools and armored cable is strongly recommended. Use extreme care
when working with severed armor. There will be a sharp edge where armor is cut. To minimize
the chance of injury from the cut armor, cover the exposed edge with a wrap of electrical tape. To
minimize the chance of injury from sharp-bladed tools, always cut away from yourself and others.
Dispose of used blades and armor scrap properly.
CAUTION: Cleaved or broken glass bers are very sharp and can pierce the skin easily. Do not
let these pieces of ber stick to your clothing or drop in the work area where they can cause injury
later. Use tweezers to pick up cleaved or broken pieces of glass bers and place them on a loop of
tape kept for that purpose alone. Good housekeeping is very important.
