PLANNING SPOIL PILES
To prevent cave-in's, place spoil pile at least 1 m (3 ft)
away from excavation. The deeper the excavation the
further the spoil pile should be placed from the
excavation. Place spoil piles for convenient truck loading
or backfilling.
On slopes, place spoil piles on the upper side of the slope
for improved machine stability and easier backfilling.

TRENCHING
Before starting work, walk the site to uncover hazards and
to plan the job. Check for buried utility lines and pipes and
for gas and oil pipelines.
To prevent cave-in's, dig a 'V' shaped trench and place
spoil piles at least 1 m (3 ft) away from trench. The
deeper the trench, the further the spoil pile should be
placed from it.
