Abstract [sv]

I oktober 2013 genomfördes sex fullskaliga brandförsök med kombinerat förflyttnings och släckmoment i Björka Minerals dolomitgruva i Tisbrottet i Sala. Tidigare har dessa två moment inte kombinerats under kontrollerade former där mätningar och observationer dokumenterats i så omfattande grad som i denna försöksserie. Rökdykarnas uppgift vid samtliga av försöken var att avancera in i tunneln och släcka branden. De sex olika försöken utgjordes av konventionell slangutläggning med slangkorgar respektive bärsele, utlägg med tomt system fram till brandplatsen, CAFS, skärsläckare och konventionell slangutläggning med hjälp av materielvagn och depåluft. Försöken visade att konventionell slangutläggning tar lång tid i anspråk, men att utlägg med tomt system och bärsele kan korta tiderna och minska belastningen. Försöken visade också att system med lägre vattenflöden hade möjligheter att slå ner branden, men att mängden vatten var avgörande för att undvika återantändning. Värmekameror är generellt inte anpassade för tunnelmiljöer och ett stort behov finns för vidare utveckling av både utrustning och utbildningsmaterial.

Abstract [en]

In October 2013 six full-scale fire tests were performed with combined movement and extinguishing in the Tistbrottet Mine in Sala. Earlier these two parts have not been combined under controlled test conditions, where measurements and observations have been documented as thouroughly, as in the Tistbrottet test series. The BA fire fighters task, in all performed tests, were to advance into the tunnel and extinguish the fire. The six different tests were represented of conventional hose lay-out with hose baskets, conventional hose lay-out with hose harnesses, full hose lay-out with empty system until reaching the scene of the fire, CAFS, cutting extinguisher and conventional hose lay-out with wagon aided movement and depot air supply. The tests showed that conventional hose lay-out with water filled hoses is time consuming, but that bot hose harnesses and later filling of the hoses can shorten the time. It was also shown that systems with lower water flows initially effectively can fight the fire, but that the amount of applied water is cruicial for if re-ignition occurs or not. Thermal image cameras are generally not customized for use in underground constructions and further development of both equipment and education material is needed.
