At what temperature and exposure duration does cell death due to burns occur, according to studies on human tissue tolerance?

• A. 200°F in 0.5 seconds
• B. 203°F in 0.1 seconds
• C. 150°F in 1 second
• D. 250°F in 0.2 seconds

Answer: (B)

The correct answer reflects that at 203°F and an exposure time of just 0.1 seconds, human tissue begins to experience cell death due to thermal burns. This conclusion is supported by studies on human tissue tolerance, which highlight how quickly severe damage can occur at elevated temperatures. Temperature plays a crucial role in tissue response; as the temperature increases, the risk of burns intensifies significantly. At 203°F, which is slightly above the boiling point of water, the potential for damage escalates rapidly. The very brief exposure duration of 0.1 seconds indicates that even contact for a minimal fraction of a second at this temperature can cause irreversible damage to cells. The extremely short time required for cell death at this temperature underscores the need for immediate action if anyone is exposed to such conditions, highlighting the importance of understanding thermal risks in electrical safety and utility practices.
