Rules for the Use of Elevators during a Fire Incident in a High-Rise Building:
First and foremost, the priority should be given to the evacuation of people, and elevators should not be used for this purpose during a fire incident unless authorized by the fire department.
Elevators should be used only by trained firefighters or building personnel, and only for specific purposes, such as search and rescue, access to the fire floor, or transport of equipment.
The use of elevators during a fire should be restricted to the non-fire floors, and firefighters should never use the elevator to go up to the fire floor.
Before using an elevator, the firefighter should check the elevator lobby for any signs of smoke, heat, or fire, and if there are any such signs, the elevator should not be used.
The firefighter should ensure that the elevator call buttons are in the "fire service" mode, which will prevent the elevator from stopping at any floor other than the designated floor.
The firefighter should carry a radio or communication device to stay in contact with the Incident Commander and other firefighters, and should inform the Command Post of their location and intended use of the elevator.
Finally, if an elevator becomes inoperative, it should be properly marked and reported to the Command Post.
Stack Effect is a natural phenomenon that occurs in high-rise buildings due to the difference in temperature and pressure between the inside and outside of the building. In simpler terms, as the warm air inside the building rises and escapes through openings such as windows and ventilation shafts, it creates a vacuum at the lower levels, which sucks in cold air from the outside. This creates a continuous flow of air from the bottom to the top of the building, which is known as the stack effect. In a fire incident, the stack effect can cause smoke and toxic gases to rise to higher levels of the building, making it difficult for occupants to evacuate and for firefighters to perform their duties.
Lobby Control is a critical role during a fire incident in a high-rise building. The duties of a firefighter assigned to Lobby Control include:
Controlling the access of people to the building, especially the fire floor and floors above the fire.
Directing occupants to safe areas or exit stairwells, and ensuring that they do not use the elevators or other areas that may be unsafe.
Coordinating with the Incident Commander and other firefighters to provide information on the conditions inside the building, such as the location and extent of the fire, the presence of smoke or toxic gases, and the status of the evacuation.
Keeping track of the movement of people and firefighters in and out of the building, and maintaining an accurate record of the occupants who have been evacuated or rescued.
Providing assistance to occupants who may need medical attention or other support, and coordinating with emergency medical services if necessary.
