CHAPTER 2

SAFETY PRECAUTIONS

WARNING

Before you start installation of your tower
let us warn you of the danger of letting any
part of your metal tower system touch
electrical power lines -YOU MAY BE
KILLED!

General Safety Rules

8. 

Don't climb tower; use separate ladder or

lower tower with gin pole for antenna
rotator servicing.

9.

Don't overload. The design load limit is
9.5 square feet of antenna on a two foot
mast for winds up to 50 MPH.

Hundreds of people are killed each year
because they don't use common sense when
they install their towers or antennas. It
happens more often than you realize. Someone
falls off a roof or gets electrocuted by
touching a power line with an antenna tower
or metal ladder.

There is no such thin- as a good tower site if it
near electrical power lines. Unfortunately,
iiiost tower systems, and in many cases, the
ladders used during an installation are metal. If
any metal tower part or ladder touches a power
line, it completes an electrical path from the
power line through the metal tower and the
installer (YOU!).

DO'S

1. Do install the tower away from power

lines. Check the distance to the power
lines before you start installing - we
recommend you stay a minimum of-
twice the maximum length of the tower
assembly away from all power lines.

2. Do install the tower on a calm day and

assure yourself of having plenty of
daylight to complete installation.

3.

Do stay clear if the tower starts to fall
or come in contact with power lines.

DON'TS

4. -Do call the power company to remove

fallen towers from power lines or to
help pick out a safe antenna site.

4.

Don't try to catch the tower if it starts to
fall

5

6

Don't try to remove any metal objects
from the power lines.

Don't be afraid to call the power
company for advice when picking a
tower site or removing a fallen tower
froni the power lines.

If someone is accidentally electrocuted, don't
touch him or the tower if he is still in contact
with the tower or downed power lines. Use a
dry stick, like a broom handle or wooden
ladder, etc., and in one sweep push the person
free from the tower or knock the wire away
and off the vi~aiq. Do not allow the wire to
touch the victim again. Have someone call the
power company and an ambulance.

7. Don't remove winch handle; use safety

chain with lock to secure_

5. Do crank tower-down to retracted

position when winds are anticipated to
exceed 50 mph.

1. Don't install any tower near power lines.

2. Don't install a tower on a windy day.
