Abstract
Fire event management always needs human intervention in order to extinguish
forest fires. Firemen’s equipment has reached high performance and safety
standards but high temperatures occurring in the proximity of a forest fire may
cause an increase in bodily temperature and dehydration. Therefore, it is
important to identify a distance limit at which an operator can work without
problems and complications due to the heat during forest fire fighting actions.
This work describes a new approach to find a safety limit for firemen. The
distance limit at which the operators can work without any consequence is
evaluated considering the bodily temperature increase of a man exposed for a
period of time at the thermal radiations coming from the fire. The main
characteristic of the model is the use of radiometry to evaluate the amount of
thermal energy transferred. By varying the distance between the fire and the
operator it is possible to evaluate the bodily temperature increase.
Safety distance limit is identified when human body temperature starts to be
dangerous (38.5°C).
In order to evaluate the distance safety value a fire model and an operator
model are given. The fire model is based on the international Brown and Davis
forest fire classification in order to consider some various realistic forest fire
types. The fire fighter representation is established according to physiological
and medical data in order to have a good representation of a real fireman.
The results of the model have been compared with the ones coming from
other models used for the same purpose based on probabilistic methods and the
comparison confirms the good validity of the presented model.
