Rigid Protection System of Infrastructures against Forest Fires

Abstract

The destruction caused by forest fires generates social impacts, environmental impacts, and extremely important economic impacts caused by the destruction of a wide range of infrastructures and essential goods. Therefore, as it is impossible to remove all the infrastructures from the forest and wildland–urban interface, the design of protection systems is essential. The main objective of this work is the development of a low-cost protection system, with rigid panels, requiring a simple installation, in order to protect outdoor infrastructures such as telecommunications stations, shelters, roadside enclosures, power cabinets, and other structures. A study was carried out on panels that could be used for protection in order to determine whether the protective material would be more appropriate. Taking into account the fire resistance behavior, thermal and structural properties and cost, the panels selected were the magnesium oxide fiberglass reinforced. The protection was constructed, installed on a telecommunication cabinet, and experimentally laboratory tested in a wind combustion tunnel. To collect the data InfraRed and video cameras, heat flux sensors, and thermocouples were used to determine the fire propagation, heat flux, and temperatures, respectively. The experimental data show that the low-cost protection is effective for protecting telecommunication cabinets and similar infrastructures against forest fires.
