Fire incidents during construction work of tunnels

The report summaries guidelines and solutions related to fire safety in underground facilities during the construction phase. Development of different fire scenarios in underground facilities under construction are presented. Based on different design fire scenarios evacuation analysis was carried out. The incident situation of the fire services are discussed and proposals for solutions discussed. Numerous tunnel sites under construction were visited and conclusions obtained from the visits are presented. Test with a large scale tire of a front wheel loader was conducted in order to obtain input for the design fire of construction vehicle. Recommendations for constructors and authorities as well as for fire services are given. These recommendations are based on the work carried out during the project.
