GENERAL PRECAUTIONS SAFETY Always design and maintain the roads on the jobsite so that the machines can travel safely. WORKING ON LOOSE GROUND 0. Avoid traveling or operating your machine too close to the edge of cliffs, overhangs, and deep ditches. The ground may be weak in such areas. If the ground should collapse under the weight or vibration of the machine, there is a hazard that the machine may fall or tip over. Remember that the soil after heavy rain or blasting or after earthquakes is weak in these areas. When working on embankments or near excavated ditches, there is a hazard that the weight and vibration of the machine will cause the soil to collapse.
Before starting operations, take steps to ensure that the ground is safe and to prevent the machine from rolling over or falling. DO NOT GO CLOSE TO HIGH-VOLTAGE CABLES 0. Do not travel or operate the machine near electric cables. There is a hazard of electric shock, which may cause serious injury or property damage. On jobsites where the machine may go close to electric cables, always do as follows. Before starting work near electric cables, inform the local power company of the work to be performed, and ask them to take the necessary action. A0060820 Even going close to high-voltage cables can cause electric shock, which may cause serious burns or even death.
Always maintain a safe distance (see the table on the right) between the machine and the electric cable. Check with the local power company about safe operating procedure before starting operations. To prepare for any possible emergencies, wear rubber shoes and gloves. Lay a rubber sheet on top of the seat, and be careful not to touch the chassis with any exposed part of your body. Use a signalman to give warning if the machine approaches too close to the electric cables. When carrying out operations near high voltage cables, do not let anyone come close to the machine.
If the machine should come too close or touch the electric cable, to prevent electric shock, the operator should not leave the operator's compartment until it has been confirmed that the electricity has been shut off. Also, do not let anyone come close to the machine. 2-12 Nominal Voltage Safety Distance up to 1000 V 1 m over 1 kV up to 110 kV 3 m over 110 kV up to 220 kV 4 m over 220 kV up to 380 kV 5 m with unknown nominal voltage 5 m
