ELECTRICAL ISOLATION FOR OPERATORS

Ref No: 2015038

INTRODUCTION
Electricity is all around us. It lights up our homes... powers much of the machinery and equipment that we use... and runs many of our tools. We are so used to it, most employees "take it for granted". Yet electricity can also be dangerous. Employees need to know how electricity works, and what they should do to protect themselves from its hazards.
This course has been developed to provide delegates the underpinning knowledge and skills to competently work to a safe system of work. Delegates will learn to safely and competently isolate and reverse isolate low voltage electrical installations components and equipment, in-line with company safe working procedures. 
Participants can expect to be aware of the hazards and risks involved and the legislation and regulations that apply, and to be able to use the safe systems of work and isolation procedures to protect themselves and others.
The purpose of this course is to provide basic safety isolation rules and instructions pertinent to electrical work in order to assist electrical workers in eliminating situations, practices and actions which can result in accidents to personnel and property.  It will help employees and companies reduce the risk of personal injury and equipment damage due to operator error. 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.
Safety hazards exist in any workplace. The risks of injury from unsafe handling of energy from electrical systems have increased considerably in the past few decades from personnel involved in operating and maintaining electrical facilities. This safety course has been developed to meet the need for consistent and effective safety standards for electrical workers.
Using a powerful combination of audio, full-motion video, text and colorful graphics, this Course provides the most cost-effective Safety and Regulatory Compliance training available today. The Course is divided into a number of logical sections so information is easily understood... and retained.
