SAFETY
WORK SITE HAZARDS
Before proceeding with any excavating operations it is important to
be aware of the hazards involved with this operation. Below is a list
outlining what to do to avoid some of these hazards.
•
Before starting any excavating operations, contact all utility
departments in your area and have them identify and mark any
underground system locations, (gas lines, water lines, electrical
lines, sewer lines, etc.).
•
Check your work area for any unusual ground conditions.
•
Make sure your work area is as level as possible and you will
be able to maneuver your work equipment or machine easily.
•
If you will be working near a high traffic area, (pedestrians or
cars) have a dedicated worker available to direct traffic or
install safety fencing around your work site.
•
Always be aware of all your work site dangers or distractions.
WORKING CLEARANCES
It is always a good idea to be aware of your clearances around, in front, behind and especially above your work area or travel
rout.
Because of the additional height posed by the backhoe boom 1m (3 ft.)
is added above the canopy that cannot be seen by the operator when the
machine is in the travel posture. Some basic safety precautions to pre-
vent risk are:
•
When working or traveling in an area where clearances are a prob-
lem, travel at a slow cautious speed.
•
If you are not sure of your clearances, request the aid of another
person who can guide or warn you if you get too close to objects.
•
Be aware of the dangers when working around overhead electrical
lines, high humidity may pose an electrical hazard even if your
machine clears the overhead power lines.
•
If your machine should come in contact with overhead electrical
lines, stop the machine and remain on the machine until the power
company clears the lines and it is safe to get off or move the machine.
•
If low power lines pose a greater hazard, ask the power company to remove the lines until your work is finished.
