The New Safety Formula: Bk = F2S

Without understanding the building-occupancy relationships and integrating; construction, occupancies, fire dynamics and fire behavior, risk, analysis, the art and science of firefighting, safety conscious work environment concepts and effective and well-informed incident command management, company level supervision and task level competencies…You are derelict and negligent and "not "everyone may be going home". Our current generation of buildings, construction and occupancies are not as predictable as past conventional construction; risk assessment, strategies and tactics must change to address these new rules of structural fire engagement. There is a need to gain the building construction knowledge and insights and to change and adjust operating profiles in order to safe guard companies, personnel and team compositions. It's all about understanding the building-occupancy relationships and the art and science of firefighting, Building Knowledge = Firefighter Safety (Bk=F2S)
