Which safety measure is essential when dealing with electrical equipment?

• A. Wearing insulated gloves
• B. Using a rubber mat
• C. Turning off power sources
• D. Ensuring dry working conditions

Answer: (C)

Turning off power sources is a critical safety measure when dealing with electrical equipment because it significantly reduces the risk of electric shock or electrocution. When the power is turned off, there is no electrical current flowing through the equipment, which means that you can work on it safely. This is especially important before performing maintenance or repairs on electrical systems.

The practice of de-energizing equipment ensures that it cannot become energized accidentally or during the course of maintenance activities. This is a fundamental principle in electrical safety protocols and is often highlighted in safety training to protect individuals who work with or around electrical systems. Following this procedure not only safeguards the individual involved but also minimizes the risk of potential hazards to others in the vicinity.
