What is the expected exposure for a second-degree burn according to the Stoll model?

The expected exposure for a second-degree burn according to the Stoll model is 1.2 cal/cm². This value is significant in the context of electrical safety and the assessment of potential thermal hazards during electrical maintenance or work.

The Stoll model provides a framework for estimating thermal exposure and the likelihood of burns based on the amount of energy absorbed by the skin. A second-degree burn typically results from exposure to temperatures that cause significant damage to the skin's outer layers, leading to blisters and pain. The value of 1.2 cal/cm² is indicative of the energy threshold above which skin damage of this nature can occur.

Understanding these thermal thresholds is crucial for professionals working with electrical systems, as it aids in determining appropriate protective measures, such as personal protective equipment (PPE) and safety procedures, to minimize the risks of injury from arc flashes and other thermal hazards. This knowledge helps in enforcing safety regulations and best practices in the workplace to protect workers from potential thermal incidents.
