Which of the following is NOT a common cause of electrical hazards in healthcare settings?

Proper grounding of equipment is not a common cause of electrical hazards; rather, it is a crucial safety measure designed to prevent such hazards. Grounding creates a path for electric current to safely dissipate in case of a fault, helping to protect patients and healthcare workers from electric shock and equipment malfunction. When equipment is properly grounded, it significantly reduces the risk of electrocution by ensuring that any stray electrical currents can flow safely away from users and into the ground.

In contrast, overloaded circuits, worn or damaged cords, and using non-approved equipment can lead to dangerous situations. Overloading circuits can cause overheating, which may result in electrical fires or equipment failure. Worn or damaged cords can expose conductors, increasing the risk of short circuits or electrical shocks. Similarly, using non-approved equipment can mean lacking proper safety standards, increasing the likelihood of electrical faults and hazards. Overall, understanding the role of proper grounding in preventing electrical hazards is key to maintaining safety in healthcare environments.
