           The above description is part 1 only you can refer remaining parts and section for other electrical installation,
           items devices and equipments.
           Lifting and handling of loads
           Many of the accidents reported involve injuries caused by lifting and carrying loads. A electrician may need to
           install motors, lay heavy cables, do wiring, which may involve a lot of lifting and carrying of loads. Wrong lifting
           techniques can result in injury.

           A load need not necessarily be very heavy to cause injury. The wrong way of lifting may cause injury to the
           muscles and joints even though the load is not heavy.
           Further injuries during lifting and carrying may be caused by tripping over an object and falling or striking an object
           with a load.
           Crushing of feet or hands
           Feet or hands should be so positioned that they will not be trapped by the load. Timber wedges can be used when
           raising and lowering heavy loads to ensure fingers and hands are not caught and crushed.
           Safety shoes with steel toe caps will protect the feet. (Fig 1)
           Preparaing to lift :  Load which seems light enough to carry at first will become progressively heavier, the farther
           you have to carry it.
