Safety - Section 20
Page 20-4
HAUL ROADS
• Determining the travel road at the work site is an
important for safety, maintenance and speed.
• When possible restrict travel to one direction. If it
is necessary to provide for traffic in both
directions, ensure the road is wide enough.
• When creating haul roads, orient the road so the
loaded truck passes on the side closest to the hill
face. Keep the road as straight as possible. If
curves are necessary, make the curve radius and
road width as large as possible. Ramp the
outside of curves so they are higher than the
inside.
• Limit intersections if possible. Design any
necessary
intersections
crossings.
• Install mirrors at curves with poor visibility.
• Install signs to warn of any dangers along the
road.
• Install adequate lighting and reflectors for safe
travel.
• Road grades should not exceed 10% and
emergency ramps installed for brake failures.
• Properly maintain haul roads for safe travel. Use
a grader or a dozer to smooth rough roads and
strengthen where necessary. Spray the roads
with water to prevent excessive dust and poor
visibility.

PRECAUTIONS DURING OPERATION
Prevention is the best safety program. Prevent a
potential accident by knowing the employer's safety
requirements and all necessary job site regulations.
In addition, know the proper use and care of all the
safety equipment on the truck. Only qualified opera-
tors or technicians should attempt to operate or
maintain a Komatsu machine.
Safe practices start before the operator gets to the
equipment!
BEFORE STARTING THE ENGINE
•
When walking to and from a truck, maintain a
safe distance from all machines even when the
operator is visible.
•
Before starting the engine, thoroughly check the
area for any unusual conditions that could be
dangerous.
•
Examine the road surface at the job site and
determine the best and safest method of
operation.
•
Choose an area where the ground is as
horizontal and firm as possible before performing
the operation.
•
If it is necessary to operate the machine on or
near a public road, protect pedestrians and cars
by designating a person for work site traffic duty
or by installing fences around the work site.
•
The operator must personally check the work
area, the roads to be used, and existence of
obstacles before starting operations.
•
Always determine the travel roads at the work
site. Maintain roads to ensure machine and
operator safety.
•
If travel through wet areas is necessary, check
the depth and flow of water before crossing the
shallow parts. Never drive through water which
exceeds the permissible water depth.
