3.1. Laser Handling precautions
WArninG:
Never look directly into the end of a fiber 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 magnifiers 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.
3.2. safety precautions
WArninG:
Isopropyl alcohol is flammable with a flashpoint at 54ºF. It can cause irritation to
eyes on contact. In case of contact, flush eyes with water for at least 15 minutes. Inhalation
of vapors irritates the respiratory tract. Exposure to high concentrations has a narcotic effect,
producing symptoms of dizziness, drowsiness, headache, staggering, unconsciousness and
possibly death.
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 fiber.
Pieces of glass fiber 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.
3.3.
Glass Fiber Precautions
CAution:
Cleaved or broken glass fibers are very sharp and can pierce the skin easily.
Do not let these pieces of fiber 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 fibers and place
them on a loop of tape kept for that purpose alone.
Good housekeeping is very important.
3.4.
Cable Handling Precautions
CAution:
Fiber optic cable is sensitive to excessive pulling, bending, and crushing forces.
Consult the cable specification sheet for the cable you are installing. Do not bend the cable
more sharply than the minimum recommended bend radius. Do not apply more pulling force
to the cable than specified. Do not crush the cable or allow it to kink. Doing so may cause
damage that can alter the transmission characteristics of the cable; the cable may have to be
replaced.
