Personal prints, cards and gifts, or reference for artists. Only short pulses of water need to be sprayed, otherwise the spraying modifies the equilibrium, and the gases mix instead of remaining stratified: the hot gases (initially at the ceiling) move around the room, and the temperature rises at the ground, which is dangerous for firefighters. In 1833 fire insurance companies in London merged to form The London Fire Company Establishment. Grimwood's original definition of his 1991 unified strategy stated that, "tactical ventilation is either the venting, or containment (isolation) actions by on-scene firefighters, used to take control from the outset of a fire's burning regime, in an effort to gain tactical advantage during interior structural firefighting operations.".
