Safety - Section 20 03/13 OM2032 Page 20-4 PRECAUTIONS DURING OPERATION HAUL ROADS Determining the travel road at the work site is an important for safety, maintenance and speed. 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. 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. Safe practices start before the operator gets to the equipment! Limit intersections if possible. Design any necessary intersections to provide safe crossings. BEFORE STARTING THE ENGINE When walking to and from a truck, maintain a safe distance from all machines even when the operator is visible. Install mirrors at curves with poor visibility.
Before starting the engine, thoroughly check the area for any unusual conditions that could be dangerous. Install signs to warn of any dangers along the road. Install adequate lighting and reflectors for safe travel. Examine the road surface at the job site and determine the best and safest method of operation. Road grades should not exceed 10% and emergency ramps installed for brake failures. Choose an area where the ground is as horizontal and firm as possible before performing the operation. 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.
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.
