Electrical Safety Training 2017
This online Electrical Safety course provides a well-rounded approach to the basics of electrical safety and helps increase understanding of the dangers of electricity from both a shock protection and arc flash protection point of view.
Course Overview
Approximately 30,000 non-fatal electrical shock accidents occur in the United States each year. The National Safety Council estimates that about 1,000 fatalities each year are due to electrocution, more than half of them occurring while energized systems of less than 600 V are being serviced.
Electrocution is the fourth-leading cause of industrial fatalities in the United States, after traffic, homicide, and construction accidents. The current required to light a 7.5 W, 120 V lamp, if passed across the chest, is enough to cause death. The most damaging paths through the body are those through the lungs, heart, and brain." (Quoted from the CSA Z462, Annex K)
This course is designed with the intent of educating the participant in the hazards associated with the use of electricity. Whether you are a seasoned journey person, apprentice, engineer, student or manager, this course has been designed with you in mind.
