1. Safety Precautions
Related to Networks

2. Installing network cables,
whether copper or fiber-optic, can be
dangerous. Often, cables must be
pulled through ceilings and walls
where there are obstacles or toxic
materials.

3. You should wear clothing such as
long pants, a long-sleeved shirt,
sturdy shoes that cover your feet, and
gloves to protect you from those toxic
materials. Most importantly, wear
safety glasses.

4. Safety precautions when using a
ladder:
Read the labels on the ladder, and
follow any safety instructions
written on it.
Never stand on the top rung of the
ladder. You could easily lose your
balance and fall.

5. Make sure that people in the area
know you will be working there.
Cordon off the area with caution
tape or safety cones.
When you are using a ladder that
leans up against a wall, follow the
instructions written on the ladder,
and have someone hold the ladder
to help keep it steady.

6. Safety rules when working with
cables:
The tools required to install
copper and fiber-optic cable may
cause danger through improper use.

7. When working with cables, strictly
follow these safety rules:
Make sure that the tools you are
using are in good working
condition.
Watch what you are doing, and
take your time. Make sure that
you do not cut yourself or place
anyone in danger.

8. Always wear safety glasses when
cutting, stripping, or splicing
cables of any kind. Tiny fragments
can injure your eyes.
Wear gloves whenever possible,
and dispose any waste properly.

9. Fiber-Optic Safety
Fiber-optic cables are useful for
communications, but they have
certain hazards.

10. Certain Hazards
Dangerous chemicals
Tools with sharp edges
Light which you cannot see that
can burn your eyes
Glass shards produced by cutting
fiber-optic cable that can cause
bodily harm

11. Specific types of tools and chemicals
are used when working with fiber-
optic cable. These materials must be
handled with care.

12. Chemicals
The solvents and glues used with
fiber optics are dangerous. You
should handle them with extreme
care. Read the instructions on the
label, and follow them carefully. Also,
read the material safety data sheet
(MSDS) that accompanies the
chemicals to know how to treat
someone in case of emergency.

13. Tools
When working with any tool,
safety should always be your first
priority. Any compromise in safety
could result in serious injury or even
death. The tools used for working
with fiber optics have sharp cutting
surfaces that are used to scribe glass.

14. Glass Shards
The process of cutting and
trimming the strands of fiber-optic
cables can produce tiny fragments of
glass or plastic that can penetrate
your eyes or skin and cause severe
irritation.

15. When you work with fiber-optic
cabling, the working surface should
be a dark mat so that you can see the
tiny glass or plastic fragments. The
mat should also be resistant to
chemical spills.

16. Harmful Light
Protect your eyes from the
harmful light that may be in the fiber-
optic strands. The light is a color that
humans cannot see. It can damage
your eyes before you can feel it. When
you use a magnifier to inspect fiber-
optic cable and connectors, the light
emitted from the fiber could be
directed into your eyes.

17. Caution:
Obtain proper training before you
attempt to cut, strip, or splice fiber-
optic cable. An experienced
technician should supervise you until
you become adequately skilled.
