You can protect against electrical hazards by the correct use of the following measures:

PROPER WIRING

All new, permanent or temporary electrical installations, or the replacement, modification, repair or rehabilitation of any electrical installation must be made in compliance with the requirements of the National Electrical code (NEC) of the National Fire Protection Association (NFPA). Electrical power distribution systems must be equipped with over current protection such as fuses or circuit breakers, which must never exceed the rated capacity of the circuit. All newly installed receptacles must be of the grounding type.

GROUNDING AND BONDING

Grounding eliminates a difference in electrical potential between a conductive object and the ground by connecting them. Grounding will protect you from electrical shock by providing a path which offers less resistance to the current than you do. Bonding eliminates a difference of potential between conductive objects. All exposed, non-current-carrying metal parts of fixed and portable equipment which are liable to become energized must be grounded.

INSULATION

If you work continually with or around electricity, you should wear rubber-soled footwear to guard against slipping and to provide insulation. Portable tools or appliances protected by an approved (Underwriters' Laboratories) system of double insulation or its equivalent need not be grounded. Where such a system is employed, the equipment must be distinctly marked. Avoid using electrical equipment or tools where there is moisture present. If it is unavoidable to do so, use ground fault circuit interrupters. Use a wooden or fiberglass ladder instead of a metal one, if work requires the use of a ladder around electrical equipment.
