High-rise buildings (post 1948), built higher, more tightly sealed, and with open-landscaped floors, increase the likelihood of fires reaching flashpoint and the potential for backdrafts. Effective exposure protection across multiple lines in high-rise fires, is both slow and difficult, affecting issues of personnel safety, both compounded by needing to ensure sufficient resources are used for quenching a fire, as well as the effects of smoke, on a tiring attacking crew. Providing vital ventilation, through the usual vertical method (by breaking the glass from the floor above), risks spreading the fire to upper floors, this is therefore limited to using horizontal means, thus lengthening the firefighting process considerably.
