Electricity affects almost everything we do. Sometimes its impact is so subtle, we don’t even realize it’s there. Just about everybody depends on it and expects it to be available when it’s needed. From the businesses that use electricity to process information to suburban homeowners who rely on electricity for the basic conveniences we’ve grown accustomed to, to the rural dairy farmer who relies on electricity to operate much of his machinery, our entire country is interlaced with transmission and distribution systems that get electricity to where it’s needed when it’s needed.

The purpose of this interactive online course is to teach the basic safety principles and practices applicable to substation and switchyard maintenance work. The course describes electrical, chemical, and personal hazards that may be encountered in substations and switchyards. A general procedure for responding to imminent dangers and accidents is also presented.

At the conclusion of this course, participants should be able to identify hazards in substations and switchyards and explain why safety practices are important. They should be able to recognize hazards and unsafe practices on the job, and they should have a general understanding of how to respond to imminent dangers and accidents.
