SmokeToolVisibility

SmokeToolVisibility is a quick checker for smoke movement, fan needs, and visibility risk during fire situations. It can estimate smoke layer height, smoke extraction flow rate, and critical velocity to help reduce smoke backflow. It also gives rough values for back-layering length and fire heat release rate to support early planning. Visibility distance and evacuation time checks help you spot when escape routes may become unsafe. For emergency systems, it can check fan capacity, pressurization needs for escape paths, and airflow needs for stairwells or ducts. The app is designed for rapid screening and option comparison in drills, reviews, and early design stages. Use the outputs as approximate guidance and confirm with detailed fire engineering where required.
