What health hazard is presented by electrical current flowing through the body?

• A. It may cause injury by heating tissue
• B. It may disrupt the electrical functions of cells
• C. It may cause involuntary muscle contractions
• D. All these choices are correct

Answer: (D)

Electrical current flowing through the body presents several health hazards, all of which contribute to the potential for serious injury or even death. The correct response indicates that each of the listed effects is a valid concern.

When electrical current passes through human tissue, it can indeed generate heat. This heating can result in burns to the skin and deeper tissues depending on the strength and duration of the current. This is important because such burns can lead to significant injury or complications.

Additionally, electrical current can interfere with the body's own electrical systems. The human body relies on electrical impulses for vital functions, including those of the heart and nervous system. Disruption in these functions may lead to arrhythmias (irregular heartbeats) or other severe cardiac issues, underscoring the danger posed by electrical exposure.

Moreover, the current can cause involuntary muscle contractions. This can lead to loss of control over muscles, making it difficult for a person to release their grip on an electrified object, thereby extending the duration of exposure to the harmful effects of electricity.

Given that each of these potential hazards is a significant concern on its own, "All of these choices are correct" summarizes the overall risk effectively, recognizing the multifaceted nature of the dangers associated with electrical current flowing through the
