Summary

Local burning time of a travelling fire, t = q/q″, for 250 kW/m², with the two office values from the worked example and the World Trade Center observation of about 20 min. Based on Van Rossum (2027), §4.5, §4.6 and §8.5, and National Institute of Standards and Technology (2005), p. 147.

Original illustration for Travelling fire, level 4 Expert.

Source basis: Van Rossum (2027), §4.4–4.6 (relations between energy, heat release rate, time and area; 250 kW/m² for an average building in a developed fire, §4.5), §8.5 (office mean fire load density 420 MJ/m²); Ministry of Business, Innovation and Employment (2025b), p. 22 (office design fire load energy density 800 MJ/m²); National Institute of Standards and Technology (2005), p. 147 (burnout at a location in about 20 min)
Alt text: Line chart: local burning time rises linearly from about 7 min at 100 MJ/m² to about 67 min at 1,000 MJ/m²; office points at 28 and 54 min.
