Final answer:
Personal injury when servicing electrical equipment can include eye injuries, burns, microwave or radio frequency energy exposure, and electrical shock. Thermal and shock hazards are the two main risks, which can potentially have serious consequences without proper safety systems and devices in place.
Step-by-step explanation:
When servicing electrical and electronic equipment, personal injury may occur from several sources, including eye injuries, burns, injury from microwave or radio frequency energy, and shock.
These are all known hazards when working with electricity. A thermal hazard is one of the key concerns, which occurs when excessive electric power causes undesired thermal effects like starting a fire. A shock hazard is another significant risk, happening when electric current passes through a person, with varying severity from mild discomfort to lethal outcomes. To mitigate these risks, various safety systems and devices are used.
