What safety practice should be followed when measuring in wet conditions?

When measuring in wet conditions, wearing rubber-insulated gloves and boots is crucial for ensuring personal safety. Wet environments increase the risk of electrical shock due to the enhanced conductivity of water, which can allow electricity to pass through more easily. Rubber is an effective insulator against electric currents, so using rubber-insulated gloves and boots significantly reduces the risk of electrical shock.

This safety practice is vital, particularly when handling electrical measurement devices that may not be designed for use in wet conditions. It provides a barrier between the user and any live components or exposed wires, helping to prevent accidental electrocution.

Utilizing standard equipment without appropriate safety precautions or failing to ensure that the area is dry compromises safety by exposing users to unnecessary risk. While battery-operated devices might reduce the risk compared to plug-in equipment, they do not replace the fundamental need for personal protective equipment when working in potentially hazardous conditions. Thus, emphasizing protective gear like rubber insulation remains the best practice in wet environments.
