Why should staff avoid using metal objects near electrical equipment?

Using metal objects near electrical equipment is particularly dangerous because metal is an excellent conductor of electricity. When metal comes into contact with live electrical components, it can provide a direct pathway for electricity to flow, significantly increasing the risk of electrocution for anyone handling those objects. This is critical in healthcare environments, where electrical equipment is often used near patients. Ensuring that metal objects are kept away from such equipment reduces the risk of accidental electrical shocks and helps maintain a safer environment for both staff and patients.

While the other choices address various concerns about metal interactions with equipment, they do not capture the most immediate and serious threat posed by metal in proximity to electrical sources. The primary concern remains the potential for electric shock and injury as a direct result of metal's conductive properties.
