||Ventilating a fire compartment during operational fire fighting procedures may have unpredictable consequences. In some cases the ventilation is advantageous: the hot gases are removed from the fire enclosure, the visibility improves and the enclosure cools down. In some cases the opposite happens: the burning rate accelerates, more smoke is spread around, and the temperatures rise. The most dramatic consequence is a severe explosion. The effect of ventilating the fire compartment was studied systematically by quarter-scale laboratory tests. Both natural and positive pressure ventilation (PPV) were applied. The tests revealed that when properly used, PPV clearly improves the survival probability in the compartment.
