What is a potential hazard of electrical shock?

• A. Fainting
• B. Loss of muscle control
• C. Excessive laughing
• D. Improved reflexes

Answer: (B)

Loss of muscle control is a potential hazard of electrical shock because the electric current can interfere with the nervous system's ability to send signals to the muscles. When a person experiences electrical shock, the current can cause involuntary muscle contractions, spasms, or paralysis, which can lead to a dangerous situation if, for example, the individual is in a precarious position or unable to control their movements. This can also prevent the person from effectively responding to safety measures or escaping from the source of the shock.

Fainting, although a potential response to shock or trauma, is less directly related to the effects of electrical current on muscle function. Excessive laughing and improved reflexes are not associated with electrical shock and do not reflect the physiological responses typically observed during such an event.
