Chapter 2 Summary
Safety is the first step to performing a job well. Many considerations are involved when
working with electrical systems. You need to be familiar with OSHA regulations as well as the
NEC before beginning a job. Electrical systems can pose multiple hazards, such as shock,
burns, and falls. You should always be aware of the job environment and take care to protect
yourself from injury.
Utilizing PPE and proper electrical safety procedures reduces the risk of injury to a min-
imum. Procedures like tagging and lockout allow you to do electrical jobs safely. Daily inspec-
tion of tools and job equipment is also necessary. Choosing to use a broken tool or ladder can
pose a serious threat to the worker. An overall knowledge of safety basics combined with
common sense goes a long way in protecting you from injury or even death.
