Course Description

Electrical safety plays an important role in electrical power systems in maintaining the safety to human being and equipment. Also it will maintain the continuity of power supply and power quality to the industrial and commercial consumers. A properly plan, design and operation of the electrical power system should ensure the safety and reliability of the system.

Understanding the steps and procedures employed in a good electrical safety program requires an understanding of the nature of electrical hazards. Understanding the nature of the hazards is useless unless protective strategies are developed to protect the worker. This course includes a synopsis of the types of protective strategies that should be used to protect the worker.

This course covers all aspects of safety issues of Electrical power system including regulatory and environmental requirements, general design considerations, application of switching and power equipment, and safe grounding design.

Course Objective

To present the recommended practices, and guides, of which NFPA 70E contained, which are developed through a consensus standards development process approved by the American National Standards Institute.
To provide The Safety Standards.
To provide a practical understanding of electrical power system safety.
To declare the regulatory and legal safety requirements.
To demonstrate the earthing systems Safety and Risk Assessment.
To explain the relation between maintenance activities for various equipment and safety.
To select and maintain the electrical equipment in hazardous areas and its standard.
To indicate arc flash hazard and mitigation.
To introduce main recommendations for electrical safety.
To review of general work and plant safety rules.
