Building safety features are important components of any structure, as they help to protect occupants from potential hazards. An EXIT is a way out of a building in case of an emergency, and is typically marked with a sign or illuminated light. A firewall is a barrier designed to prevent the spread of fire between different parts of a building. Rails are often used to provide support and stability to staircases, balconies, and other areas of a building. Airbags are a type of cushioning system that can be installed in walls and ceilings to absorb shock and reduce the risk of injury. Finally, a sprinkler system is an automated system of pipes and nozzles that can be used to extinguish fires quickly and efficiently.
