Which model is used in NFPA 70E informational notes to relate arc energy to skin burn injury?

• A. Stoll model
• B. Arrhenius model
• C. Humes model
• D. Newton model

Answer: (A)

Relating arc energy to skin burn injury relies on an empirical way to translate how much heat hits the skin and for how long into how severe a burn could be. NFPA 70E informational notes use a practical link between incident energy (cal/cm^2) and predicted burn depths, built from experimental data, to help estimate injury risk and guide protection decisions. The model chosen for this purpose is the Stoll model, which directly connects energy exposure to burn severity and provides burn-depth thresholds that clinicians and safety professionals can use in hazard analysis. The Arrhenius model, while a fundamental description of reaction rates with temperature, is not tailored to arc burn injury assessment in the NFPA 70E notes. Newton or Humes models aren’t the standard reference used in these notes for this specific linkage. So, the Stoll model is the best fit for relating arc energy to skin burn injury in NFPA 70E.
