Electrical System Safety Hazards and Safegurads

This course covers the knowledge and skills needed to safely work with energized high-voltage high-energy electric power systems. Principles and procedures for the safe operation and maintenance of high voltage systems are covered. Insulated hand tools,  "hot-sticks", proper grounding procedures,  proper protective clothing, and thorough job-planning procedures are stressed throughout the course. Properties of electric charge, energy, electric potential, dielectric stress, capacitive and inductive coupling, and material behavior in electromagnetic fields are covered. The effects of electrical energy on humans and various protection concepts are addressed, as are basic first aid practices. Differential protection schemes, insulation materials, Faraday cages, equi-potential grounding, live-line tools, and isolation techniques are covered from both the technical and practical perspectives.

This course is designed to train all electrical staff on the proper care, maintenance, inspection and utilization of the power distribution system. It is also designed to ensure that delegates are instructed to work within the guidelines of Electrical Utility Safety Association and OSHA safety regulations. It will help employees and companies reduce the risk of personal injury and equipment damage due to mishandling. The course is also designed to ensure that, under emergency conditions, the proper steps are taken to restore power in an efficient and safe manner.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

• Explain the electrical safety standards and regulations including voltages
• Understand the hazards of electricity at the power system supply level
• Review the principles, governmental regulations, work practices and specialized equipment relating to electrical safety

Who Should Attend?

This course is valuable for those Industrial and commercial electrical maintenance personnel, engineers, supervisors, and safety personnel who work on or near energized and de-energized electrical equipment and systems, and other personnel classified as "qualified".
