done safe and quickly.)
o Warn others that a gas line has been
cut and that they should leave the
area. This may include nearby homes
or buildings. If jobsite is along a street,
stop traffic.
o Leave jobsite as quickly as possible.
Immediately call your local emergency

Keep all bystanders away.
Before operating the vacuum
excavator, make sure to be familiar
with all controls and functions.
Maintain in line of sight to any
moving components such as the
debris tank door, debris tank, and
boom.
Follow proper procedures in the
operator's manual.
Know what you are vacuuming and
what may already be in the tank.
Keep suction hose away from face
and body parts.
Shut off the engine to correct the
clogged hose.
Never open any component when
the unit is operating in reverse flow.
Switch to vacuum or shut off
engine before opening any system
component.
Keep unit in “vacuum” mode unless
pressure is needed.
Restrain hose prior to
pressurization.
Do not use pressure to clear clogs
in vacuum hose.
Always identify all overhead power
lines prior to the start of excavation.
Always stay away from overhead
electric lines while operating raised
equipment or boom.
Follow regulations for working
around overhead power lines. If
voltage is unknown, equipment
must be kept at least 20 feet away

Disposal of spoils
from energized powerlines.
Assume all electrical lines are
energized and uninsulated.
If you must work near overhead
energized lines:
De-energize lines if possible.
Make sure required distance is
maintained.
Have a spotter to ensure required
distance is maintained.
Meet with all required personnel at
the jobsite and ensure to review the
location of the powerlines and
precautions to take as well as the
areas to avoid.
•
Regulations for disposal of spoil
tank contents vary from job to job.
•
Some jobs do not allow excavated
soil to be placed back into the
excavation if it has been mixed with
water.
•
Only dispose contents in approved
locations.
