What is a fundamental safety consideration when working near energized equipment?

When working near energized equipment, checking voltage differences is a fundamental safety consideration because it helps identify potential hazards associated with electrical shock or malfunction. Understanding the voltage levels in the area ensures that individuals can assess whether they are operating within safe limits. High voltage differences can lead to arcing or unintended current flow, posing serious risks to personnel. Being aware of these differences is crucial for planning safe work practices and implementing appropriate protective measures to prevent accidents.

This focus on voltage differences is critical because electrical energy can cause severe injuries or fatalities. Workers need to know the specific conditions they are facing, including the presence of high voltages, to take the necessary precautions, such as maintaining safe distances or using insulated tools.
