What are the general safety hazards of temporary power and piling machines in the construction site?
General sites are! Lose cable! High voltage electricity wounding! Poor site results in equipment tilting
3, the night construction should be safe and meet the lighting, lighting equipment and components should be consistent with the quality of the current national mandatory standards, not allowed to use insulation aging or damaged appliances and devices. In the event of a sudden power failure, the staff needs to evacuate the working place in time, it is necessary to install emergency lighting equipment with its own power supply.4, mobile power tools, hand-held power tools should be maintained before use, grounding, and the use of safety voltage. Electric tool load line should select type of weather resistant rubber sheathed copper cable and any joint. When using hand-held power tools, it is necessary to wear and wear protective clothing according to the rules.5, the use of self generating units, there should be special management.
Piling machine electrical short circuit can not strike fire, need temporary power consumption precautions:The construction site of 1 piles and electricity should be used temporarily laying cable laying, temporary power lines should be in conformity with the special safety electricity demand, cable line of mobile often demand, should be laid by vehicle rolling, trampled and pipe, where the workpiece collision is not easy, and may not be placed in soil and water. The electrician needs at least one power outage every week to check the outer wear of the cable and find that the problems need to be dealt with in a timely manner. When the cable goes through a temporary route, it uses a steel pipe as a sheath, trenching, laying underground, and setting a firm and significant azimuth symbol.2, temporary power construction, it is necessary to set up special switch cabinet or switch box, cabinets (boxes) necessary equipment over-current, overload, short-circuit and leakage maintenance equipment. Mechanical equipment and maintenance of the switch cabinet is provided with neutral or ground, switch cabinet (box), anti rain (tide) and cabinet (box) within the switch electrical equipment, switch cabinet (box) with "electric temporary construction site safety technical specification shall be the equipment".
