poistumistiekäytössä

Poistumistiekäytössä refers to the Finnish term for "in use as an exit route". This designation is primarily applied in building safety regulations and refers to pathways, stairwells, and doors that are specifically intended and maintained for the evacuation of people from a building in case of fire or other emergencies. Ensuring that these routes are clear, well-marked, and accessible is a critical aspect of fire safety planning and building code compliance.

The term emphasizes that these areas are not for general circulation or storage but are exclusively reserved for emergency egress. Obstructions, such as furniture, equipment, or stored materials, are strictly prohibited in poistumistiekäytössä areas to guarantee that they remain unobstructed and safe for rapid escape. Fire doors within these routes must also be kept closed or be self-closing to maintain their fire-resistance rating and prevent the spread of smoke and flames. Signage, including emergency lighting, is crucial for clearly identifying and illuminating these exit paths, especially in low-visibility conditions that can occur during an emergency. Regular inspections and maintenance are necessary to ensure that all aspects of the poistumistiekäytössä remain in compliance with safety standards and are fully functional when needed.
