OM2036 08/11 Safety - Section 20 Page 20-7 Ensuring Good Visibility When working in dark places, install work lamps and headlamps. The following actions are effective in preventing acci- dents while working near high voltages: Wear shoes with rubber or leather soles. Safely stop the truck if visibility is poor, such as in mist, snow, or rain. Wait for the weather to improve to allow safe travel. Use a signalman to give warning if the machine approaches an electric cable. If the work equipment must touch an electric cable, the operator must remain in the cab. Operating On Snow When working on snowy or icy roads, there is danger that the machine may slip on even the slightest slope.
Travel slowly and avoid sudden starting, turning, or stopping in these conditions. When working near high-voltage cables, DO NOT allow anyone to approach the machine. Check with the electrical maintenance department about the voltage of the cables before operating the truck. Use caution when clearing snow. The road shoulder and other objects may be buried in the snow and cannot be seen. When Loading The Truck Ensure the surrounding area is safe. If so, stop the machine in the correct loading position and evenly load the body.
Avoid Damage To The Dump Body When working in tunnels, on bridges, under electric cables, or when entering an enclosed area where there are height limits, use extreme caution. The dump body must be completely lowered before driving. DO NOT leave the operator's seat during loading. When Dumping Before starting, 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.
Driving with a raised dump body, or raising the dump body in an enclosed area, may result in serious damage and bodily injury or death. Drive with the dump body resting on the frame. When dumping on slopes, machine stability is poor and there is danger of tip over. Avoid dumping on slopes whenever possible. Driving Near High-Voltage Cables DO NOT travel with the dump body raised. Driving near high-voltage cables can cause electric shock. Maintain the safe distances between the machine and the electric cable, as listed below. 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 and result in serious injury or death. Remember that ground surfaces in these areas may be weakened after heavy rain or blasting. Freshly laid soil and the soil near ditches is loose. It can collapse under the weight or vibration of the machine. Avoid these areas whenever possible.
