Rökavskiljningar

Rökavskiljningar are fire safety devices designed to compartmentalize buildings and prevent the spread of smoke during a fire. Their primary function is to create barriers that limit the movement of smoke, thereby improving evacuation times and protecting escape routes. These systems are often integrated into ventilation and air conditioning systems, or they can be standalone units.

The principle behind rökavskiljningar is to create negative pressure zones in areas where smoke might accumulate, drawing the smoke away from occupied spaces and directing it towards exhaust systems. Alternatively, some systems work by creating positive pressure in protected areas, pushing smoke out and maintaining breathable air. They can also involve physical barriers like smoke curtains or fire doors that automatically close in response to heat or smoke detection.

The effectiveness of rökavskiljningar is crucial for life safety in buildings. They are particularly important in high-rise buildings, hospitals, and public assembly spaces where rapid smoke dissemination can pose a severe threat. Proper design, installation, and regular maintenance are essential to ensure these systems function correctly in an emergency. Regulations and building codes in many countries specify the requirements for rökavskiljningar to ensure adequate protection against smoke spread.
