What should be done before starting work on electrical systems?

Before starting work on electrical systems, it is crucial to ensure that all power sources are off and properly locked out when necessary. This is a fundamental safety procedure designed to protect electricians and other workers from accidents such as electric shock or electrocution. Lockout/tagout (LOTO) protocols help ensure that energy sources are disconnected and cannot be accidentally re-energized while maintenance or repairs are being performed.

The importance of this practice cannot be overstated, as working on live circuits or systems poses significant risks not only to the individual performing the task but also to others nearby. Following standard safety protocols, including confirming that all power sources are de-energized and secured, forms the cornerstone of a safe working environment in electrical work. By prioritizing this step, electricians can effectively mitigate hazards associated with electrical systems, thereby supporting their own safety as well as that of their colleagues.
