Course Overview

In recent years, the electrical community has begun to understand that workers are exposed to many different electrical hazards. Workers certainly should not be unnecessarily exposed to hazards. Workers should understand how and when they could be exposed to a hazard and how to assess the hazard and risk of injury. 

Historically, the purpose of a hazardous area classification was to designate locations where flammable materials may be present and to determine the electrical protection and wiring methods suitable for the environment. The documentation was primarily referenced by the electrical installation codes and standards and was primarily used by electrical and instrumentation personnel for facility construction purposes.

They must also understand how to select and use work practices that minimize or eliminate risk of injury and how to select and wear protective equipment that will minimize or eliminate that risk. Employees must understand the concepts discussed in this course. Providing a safe work place is not only an economical asset, it is the right thing to do.

Course Objectives

At the end of the program, participants will be able to:

• Be aware with the basic concept of electricity

• Be familiar with the effects of electricity in the human body

• Be able to recognize common electrical hazards
