Distance To High Voltage Cables; Ensure Good Visibility - Komatsu GALEO PC200 Manual

SAFETY

DISTANCE TO HIGH VOLTAGE CABLES

Do not travel or operate the machine near electric cables.
There is a hazard of electric shock, which may cause serious
injury or property damage. On jobsites where the machine may
go close to electric cables, always do as follows.
Before starting work near electric cables, inform the local
power company of the work to be performed, and ask them
to take the necessary action.
Even going close to high-voltage cables can cause electric
shock, which may cause serious burns or even death.
Always maintain a safe distance (see the table on the right)
between the machine and the electric cable. Check with
the local power company about safe operating procedure
before starting operations.
To prepare for any possible emergencies, wear rubber
shoes and gloves. Lay a rubber sheet on top of the seat,
and be careful not to touch the chassis with any exposed
part of your body.
Use a signalman to give warning if the machine
approaches too close to the electric cables.
When carrying out operations near high voltage cables, do
not let anyone come close to the machine.
If the machine should come too close or touch the electric
cable, to prevent electric shock, the operator should not
leave the operator's compartment until it has been con-
firmed that the electricity has been shut off.
Also, do not let anyone come close to the machine.

ENSURE GOOD VISIBILITY

Check for any persons or obstacles in the area around the machine and check the conditions of the jobsite to
ensure that operations and travel can be carried out safely. Always do as follows.
When working in dark places, turn on the working lamp and front lamps installed to the machine, and set
up additional lighting in the work area if necessary.
Stop operations if the visibility is poor, such as in mist, snow, rain, or dust.
