OSHA 30 Hour Construction Program Practice Test

What factors determine the severity of an electric shock?

1. The type of machinery used

2. The path of current through the body

3. The voltage used

4. The weather conditions

The correct answer is: The path of current through the body

The severity of an electric shock is primarily determined by the path of the current through the body. When an electrical current passes through the human body, it can affect various organs and systems depending on the route it takes. For instance, if the current flows through the heart, it can disrupt cardiac function and potentially lead to fatal arrhythmias. Alternatively, if the current travels through less critical areas, the effects may be less severe. Additionally, the specific characteristics of the current, such as its intensity and duration, can also play a significant role in the severity of the shock, but the pathway through which it travels is a critical factor that dictates potential injury. Understanding the routes that electrical current may take through the body enables safety professionals and workers to assess risks and implement adequate safety measures to prevent electric shock incidents.
