Abstract The purpose of this report is to outline the importance of electrical safety by giving examples of unsafe electrical practices and their effects. This report will also show proper procedures when dealing with electricity and the importance of protective equipment.
History Man’s fascination with electricity can be traced back to the early 1700’s Electrical engineering is now the largest branch of the engineering field. Electricity is now a major part of everyday life
What is Electricity Electricity is a group of negatively charged electrons In order for electricity to flow it requires a circuit The flow of electrons is called current That flow is caused by voltage
Dangers of Electricity Effects of Current in the Human Body .001 amperes is enough to cause a slight shock .1 amperes if held for more than a second can be fatal From 1982 – 1994 electrocutions were the fifth leading cause of workplace fatalities.
Causes of Electrical Mishaps Electrical overloads A larger current exists than was intended for the conductor Electrical Shorts A current is provided an alternate path than the one that was designed in the circuit The alternate path can not handle the amount of current passing through it
Safety Procedures Always wear proper safety equipment Gear that acts as an insulator Never handle electricity when wet Replace or repair equipment that is not functioning properly Ensure equipment is properly grounded Use surge protectors, fuses and circuit breakers to protect against shorts and overloads
