The MFD Fire Training Division recently completed commercial roof operations training at Westgate Mall through our acquired structure program. All ladder companies in the city attended this training.
In six days, over 50 ventilation holes were cut with over 100 of our members taking part in the training.
Commercial buildings present a unique challenge to firefighting operations and ventilation tactics. Multiple layers of insulation and roofing materials must be removed to expose the roof. Crews can then identify where they need to cut the hole to avoid hitting any joists and perform the ventilation quickly. This operation requires multiple saws and crew members and is a labor-intensive assignment.
Vertical ventilation allows the fire attack and search & rescue companies below to perform their tasks faster by removing heat, smoke, and steam. There is a high level of coordination between the roof team and those operating below to open the hole at the right time and to avoid any unsafe practices.
This particular roof had a rubber membrane, two layers of insulation, and corrugated metal decking to cut through.
