DANGER
Contacting underground hazards with the
machine while drilling or reaming can cause
explosion, electrocution, breathing problems,
severe trauma, and death to you or bystanders.
– Ensure that all personnel at the job site wear
personal protective equipment including
a hard hat, eye protection, and hearing
protection.
– Keep bystanders and spectators away from
the job site, including the complete bore
path.
– Locate and expose all electric and gas lines
that you will be crossing by careful hand
digging.
– Ensure that you use the Zap-Alert system
whenever you operate the machine.
Common hazards include the following:
–
Gas lines
DANGER
Drilling into a gas line can cause an explosion
or fire, burning, injuring, or killing you or
others in the vicinity of the break.
◊ Do not smoke or have any source of flame
near gas lines or at either end of a bore
that will be crossing a gas line.
◊ Keep bystanders and spectators away
from the job site, including the complete
bore path.
◊ Locate and expose all gas lines that you
will be crossing by careful hand digging.
◊ Have the gas company turn off the gas
to any lines you will be crossing before
drilling.
◊ Use the receiver to track the exact position
of the drill head when approaching gas
lines.
–
Electrical power lines
DANGER
Drilling into an electric power line will cause
the machine to become electrified and may
electrocute you or any bystanders.
◊ Keep bystanders and spectators away
from the job site, including the complete
bore path.
◊ Locate and expose all electric lines that
you will be crossing by careful hand
digging.
◊ Have the electric company turn off the
power to any lines you will be crossing
before drilling.
◊ Use the receiver to track the exact
position of the drill head when
approaching electric lines.
◊ Before drilling, setup and use the
Zap-alert system which is designed to
notify in the case of an electric strike and
electrically isolate the machine operator
from the machine. If the Zap-alert alarm
triggers, stop what you are doing and do
not leave the operator’s position. Refer
to
Deploying the Zap-alert System (page
67)
for detailed instructions on using the
Zap-alert system.
