Stairs – Elevator Pressurization Systems
Stair-elevator pressurization systems; These are the systems created to evacuate people in case of negativities such as fire in production facilities and businesses. The main purpose of the system; to create a safe area necessary for human evacuation and to prevent people from being harmed by the negative effects of fire.
Smoke emerging at the time of fire has a tendency to move on the ventilation areas inside the building to a large extent. Such areas are mostly stairs and elevator shafts. The dense accumulation of smoke in areas where it is not possible to evacuate such smoke passage not only makes it difficult for people to evacuate, but also makes it difficult for firefighters working in firefighting.
What are Stairs – Elevator Pressurization Systems?
Stair-elevator pressurization systems are systems that are specially designed to make evacuation safe from structures in case of fire and to facilitate firefighting. The system creates more pressure in areas such as elevators and stairwells than in the living area, creating suitable space for evacuation. Vertical shafts positioned in stairs and elevator shafts increase pressure and prevent smoke entry.
Stair-elevator pressurization systems should be used in different standards in each building. Stair-elevator pressurization systems, categorized according to their structural features and pressure effect, have been designed according to the principles specified in Article 89 within the scope of the Regulation on the Protection of Buildings from Fire. The relevant article clearly states which systems should be used for each structure.
Stairs – Elevator Pressurization Systems Features
Stair-elevator pressurization systems have a simple and highly effective working principle. As stated by law, the main purpose of these systems is to protect the structures from the negative effects of fire and to create a suitable ground for human evacuation. In this direction, pressurization systems can be defined as the most effective method that can provide human evacuation in escape areas with very low costs.
Another important effect of stair-elevator pressurization systems is to enable firefighters to intervene in the fire area in a correct, fast and healthy way. Stair-elevator pressurization systems, which are also designed according to the principles specified in the relevant regulation, enable firefighters to intervene effectively in the fire area in the event of a fire. It creates a smoke-free environment and fire fighting teams can easily intervene from the smoke-free area.
