area condition to ensure safe operation.
• Inspect the topography and ground
condition of the working area, or the
structure of the building when working
indoors, and take the safety precautions as
necessary.
• Be sure to avoid all hazards and
obstructions such as ditches, underground
lines, trees, cliffs, overhead electrical wires,
or places where there is a danger of falling
rocks or slides.
PRECAUTIONS WHEN PREPARING
• Check with the administrator for the
locations of buried gas pipes, water pipes
and power cables. If necessary, determine
what specific precautions must be taken to
insure safety by consulting with the
administrator.
• When working on roads, be sure to
consider the safety of pedestrians and
vehicles.
· Use a flag person and/or a signal.
· Fence off the working area and keep off
unauthorized persons.
• When working in water or crossing shallow
streams or creeks, check the depth of the
water, the solidity of the ground and the
water flow speed beforehand.
