Getting the right equipment and personnel to the right locations as safe and quick as possible.
There is a risk to those entering or exiting a high rise building, working or assembling outside from falling debris. This can be ejected explosively and materials such as glass and curtain wall panels can “plane” some distance from the building.
High rise incidents will create difficulties with lines of communication and radio reception. Building construction will cause radio reception “blind spots”
Access for firefighters may be delayed or blocked by security arrangements, such as door-code entry systems, security grilles, and multi-lock door systems. Multiple security arrangements along the route to a fire may also slow progress.
Large compartments, complex floor layouts or floor numbering systems can adversely impact safe movement and increase the risk of firefighters becoming disorientated in smoke.
There may be an insufficient water supply on upper floors due to the height of the incident, characteristics of the fire main and the limitations of fire service equipment.
Personnel may have to climb a number of flights of stairs handling and moving equipment.
Loss of elevators, lights, building systems and HVAC with complicate all firefighting operations.
The retrieval of casualties to medical care can involve transportation over a considerable distance and this can impact on their potential for survival and recovery.
Personnel involved in carrying casualties may be at increased risk of physical exhaustion and manual handling injury. This may lead to a casualty being dropped or injured. Fire and Smoke Spread
Fire and smoke in high rise buildings can spread in an upward, downward or horizontal direction. This may be more rapid and less predictable than in other building types
Air currents may lead to smoke within the building being drawn upwards or downwards. Downward smoke spread, particularly in the staircase can have a significant and adverse impact on operations
Wind speeds are likely to increase as the height of the building increases. Wind speed and direction can also be influenced by the position of other nearby building. Wind entering a fire compartment can intensify the fire creating a “blow torch” effect.
