Drop-off or Edge
When working at edge of an excavation or near a drop-off, the
machine could tip over, which can result in death or serious
injury. Always fasten your seat belt. Check ground conditions of
work site before operating to prevent the machine from falling or
roll-over, and to prevent ground, stockpiles, or banks from
collapsing.
Do not travel too close to edge of a drop-off.
Poor Visibility
For good visibility, always do the following:
•
When working in dark areas, attach working lights and
front lights to the machine. If necessary, set up additional
lighting at work site.
•
Stop operations when visibility is poor, such as in fog, mist,
snow, and rain. Wait for visibility to improve before starting
operation.
To avoid hitting work equipment and damaging other property,
always do the following:
•
When working in tunnels, on bridges, under electrical
wires, or when parking the machine or performing other
operations in places with limited height, be careful not to hit
and damage other equipment or property.
•
To prevent hitting objects, operate machine at a slow
speed when working in confined spaces, indoors, or in
crowded areas.
•
Do not swing bucket over the top of personnel or over
operator's cabin of dump truck.
Loose or Soft Ground
Do not operate on soft ground or near edge of drop-offs,
overhangs, and deep ditches. The ground can collapse because
of the weight of the machine causing the machine to fall or roll-
over.
Check ground conditions before beginning work with the
machine. If ground is soft, reposition the machine before
operating.
The excavated material must not be dumped too close to edge.
How far away from edge of trench excavated material must be
dumped depends on soil type and moisture content. If loose clay
is being excavated, place it at least 5 m (16 ft) away from edge.
If excavated material is dumped too close to edge, its weight can
cause a landslide.
Thawing of frozen ground, rain, traffic, piling and blasting are
other factors which increase risk of landslide. The risk also
increases on sloping ground. If it is not possible to dig a trench
and adequately slope its sides, always install shoring
equipment.
