What is the approximate voltage that can cause harm to an individual or equipment?

• A. 15 volts
• B. 30 volts
• C. 50 volts
• D. 100 volts

Answer: (B)

The voltage level that can potentially cause harm to an individual or equipment is typically around 30 volts. This threshold is significant because levels above this can easily pose a risk of electric shock or electrical malfunctions in various devices. The human body's resistance can vary, but anything over 30 volts can breach the skin resistance and increase the risk of electric shock, especially under certain conditions such as moisture or damaged skin. When evaluating electrical safety, it's important to consider both the voltage and the current, as well as the environment in which an individual may be exposed to electrical hazards. Voltages above the 30-volt mark can cause dangerous conditions, particularly if proper safety precautions are not observed. As such, 30 volts is often cited in safety standards when discussing the threshold above which electrical safety practices should be enforced.
