Safety - Section 20 03/13 OM2032 Page 20-8 Operate Carefully On Snow When working on snowy or icy roads, there is danger that the machine may slip to the side on even the slightest slope. Always travel slowly and avoid sudden starting, turning, or stopping in these conditions. When Dumping Before dumping, check that there is no person or objects behind the machine. Stop the machine in the desired location. Check again for persons or objects behind the machine. Give the determined signal, then slowly operate the dump body. If necessary, use blocks for the wheels or position a flagman. Use extreme caution when clearing snow.
The road shoulder and other objects are buried in the snow and cannot be seen. When dumping on slopes, machine stability is poor and there is danger of tip over. Always perform such operations using extreme care. Avoid Damage To Dump Body Always use extreme caution when working in tunnels, on bridges, under electric cables, or any other place where there are height limits. The dump body must be completely lowered before driving the machine. Never travel with the dump body raised. Working On Loose Ground Avoid operating the machine near cliffs, overhangs, and deep ditches. If these areas collapse, the machine could fall or tip over, resulting in serious injury or death.
Remember that ground surfaces in these areas may be weakened after heavy rain or blasting. Driving Near High Voltage Cables Driving near high-voltage cables can cause electric shock. Always maintain safe distances between the machine and electric cables, as listed below. Freshly laid soil and soil near ditches is loose. It can collapse under the weight or vibration of the machine. Avoid these areas whenever possible. Loading The Body Check that the surrounding area is safe, stop the machine in the correct loading position, then evenly load the body. DO NOT leave the operator's seat during loading. The following actions are effective in preventing acci- dents while working near high voltages:
Parking The Machine Wear shoes with rubber or leather soles. Choose a horizontal road surface to park the machine. If the machine must be parked on a slope, always put blocks under all the wheels to prevent the machine from moving. Use a signal person to give a warning if the machine approaches an electric cable. If the work equipment should touch an electric cable, the operator must remain in the cab. When parking on public roads, provide signals, such as flags or lights, to warn pedestrians and other vehicles. Ensure the machine, flags, or lights do not obstruct the traffic. When driving near high voltage cables, DO NOT allow anyone to approach the machine.
Check with the electrical maintenance department about the voltage of nearby cables before operating. Before leaving the machine, fully lower the dump body, activate the parking brake, stop the engine, and lock everything. Always take the key with you.
