This paper makes a statistical analysis of the casualties of firefighters in 2007-2016, and sorts out the risk factors of internal attack. On this basis, from two aspects of internal attack tactical safety awareness and internal attack technical safety measures, this paper deeply analyzes a series of internal attack safety problems such as the timing of internal attack, the establishment of internal attack command system, the danger signs and emergency measures. The research results can provide positive reference for firefighters' internal attack action safety.
