Many existing buildings do not have available information on fire safety. By assessing the building plans and through onsite inspections, The Fire Surgery can provide a retrospective fire strategy, compiling all the fire safety information in one location. This allows for better planning of future alterations to the building, as well as understanding how best to operate the building. Benefits of better understanding the fire strategy for an existing building include knowledge of maximum occupant numbers, improvements to the strategy for evacuation of disabled occupants, better property protection strategies and possibilities for including multiple tenants.
