tuletõkkesektsioon

A tuletõkkesektsioon, which translates to fire compartment in English, is a fundamental concept in fire safety engineering and building construction. Its primary purpose is to divide a building into distinct zones, each designed to contain a fire within its boundaries for a specified period. This containment is crucial for preventing the rapid spread of flames, smoke, and heat to other parts of the building, thereby allowing occupants more time to evacuate safely and providing firefighters with a more manageable situation.

The effectiveness of a tuletõkkesektsioon relies on the integrity of its enclosing elements, which typically include fire-rated walls, floors, ceilings, doors, and other penetrations. These elements are constructed with materials and designs that have been tested and certified to resist fire for a certain duration, often measured in hours (e.g., EI 60, meaning it resists fire for 60 minutes). The "E" indicates integrity (preventing the passage of flames and hot gases) and the "I" indicates insulation (limiting temperature rise on the unexposed side).

The size and layout of tuletõkkesektsioonid are determined by building codes and regulations, which consider factors such as the building's occupancy type, height, and the potential fire load. For example, hospitals and high-rise buildings will have smaller and more numerous fire compartments compared to a single-family dwelling. Proper sealing of all openings, such as those for pipes, ventilation ducts, and electrical wiring, is essential to maintain the compartmentation's integrity. Failure to do so can create pathways for fire and smoke to bypass the intended barriers, compromising the overall fire safety strategy of the building.
