During firefighting operations, any door can provide the building's occupants (and firefighters) with some protection against smoke and heat. Greg Havel reviews fire resistance of doors in residential occupancies.
Precast and tilted-up concrete walls may pose dangers to firefighters under fire conditions. Greg Havel discusses potential hazards with this construction feature.
Skylights have often been installed in churches, and firefighters need to note their presence in preincident plans to avoid getting injured when operating at these structures, Greg Havel writes.
Some builders use manufactured I-joists not only to support floors, ceilings, and flat roofs, but also in place of either sawn-lumber rafters or wood trusses to support pitched roofs. Gregory Havel discusses how this may affect firefighters during fires in such buildings.
