Which of the following is a safety requirement when servicing electrical equipment?

When servicing electrical equipment, it is essential to adhere to multiple safety requirements to minimize the risk of accidents or injuries. Each of the requirements listed contributes to a safe working environment.

Ensuring the area is dry is crucial because water or moisture can conduct electricity, increasing the risk of electrical shock. A dry environment reduces this risk significantly, making it a foundational aspect of electrical safety.

Wearing rubber gloves is another critical safety precaution. Rubber gloves provide insulation against electric shock, offering protection for the individual working on or near live electrical parts. They are designed to withstand high voltages and prevent electrical current from passing through the body.

Training for workers is essential because it equips them with the knowledge and skills to handle electrical equipment safely. A trained worker understands the hazards they may face and the proper procedures to follow, which includes recognizing the need for PPE (personal protective equipment) and safe work practices.

Together, these elements—keeping the work area dry, using appropriate PPE such as rubber gloves, and ensuring all workers are trained—represent a comprehensive approach to electrical safety. Therefore, the most complete and accurate answer is that all of these safety requirements are necessary when servicing electrical equipment.
