47. Do not use defective material.
48. Inspect all electrical equipment & devices to ensure there is no damage or exposed wires

that may causes a fire or shock.

50. Use superior quality of material (ISI mark)
51. By the use of proper rating protective devices with the electrical circuits.
52. There should not be any loose connection in the electrical installation & these should be checked periodically.
53. Electrical installation & equipments used in hazards area should be satisfied the specification/type of protection.
54. Know the work content and work sequence, especially all safety measures.
55. Know the proper tools and instruments required for the work, that they have the full capability of safely performing the work, and that they are in good repair and/or are calibrated.
56. Check to determine that all de-energized circuits and equipment are locked out and that ground are placed on all sides of the work area prior to beginning work.
57. Segregate all work areas with barriers or tapes, confine all your activities to these areas, and prevent unauthorized access to the area.
58. Insure that all energized circuits and equipment adjacent to the work area are isolated, protected, or marked by at least two methods (e.g., rubber mats, tapes, signs, etc.) for personnel protection.
59. Do not perform work on energized circuits and equipment without the direct authorization of your unit manager. When work on energized circuits and equipment has been authorized, use appropriate Safety-tested equipment (i.e., rubber gloves, sleeves, mats, insulated tools, etc.).
60. Your foreman and qualified employee must inform you of all changes in work conditions. You then must repeat this information to your foreman and qualified employee to insure your recognition and understanding of the condition.
61. Do not work alone; work with another worker or employee at all times. Do not enter an energized area without direct permission from your foreman and qualified employee.
62. Discuss each step of your work with your foreman and qualified employee before it is begun.
63. Do not directly touch an unconscious fellow worker since he or she may be in contact with an energized circuit and equipment. Use an insulated device to remove him or her from the suspect area.
64. Do not perform, or continue to perform, any work when you are in doubt about the safety procedure to be followed, the condition of the equipment, or any potential hazards. Perform this work only after you have obtained directions from your foreman and qualified employee.
