Which of the following hazards can electricity expose workers to?

Electricity can indeed expose workers to a range of hazards beyond just one type of incident. The correct option encompasses electric shock, electrocution, and explosions, highlighting the various risks associated with electrical work.

Electric shock occurs when a worker comes into contact with an electrical source, which can cause a range of health effects from minor sensations to severe injuries, depending on the voltage and current involved. Electrocution is a more severe outcome of electric shock that results in death or severe injury; this typically occurs when a person is subjected to a lethal amount of electrical current. Additionally, electricity can ignite flammable materials or cause equipment failures, leading to explosions. This risk often stems from arcing or sparking when electrical contacts are faulty or when certain conditions are present, such as moisture or flammable gases.

Recognizing the variety of hazards associated with electricity is crucial for ensuring worker safety and implementing appropriate safety measures and training. While other options may mention only one or two risks, the correct answer effectively captures the comprehensive nature of electrical hazards faced by workers.
