Egress Planning

Egress planning is typically built around occupancy size and local fire codes — which is a necessary floor, not a ceiling. ONE9 3NINE delivers hypothetical scenario testing using specialist software that inputs new or existing building designs and simulates how people would move during emergencies positioned throughout the facility. The result: evidence-based egress planning that responds to how people actually behave, not how codes assume they will.

Fire exit doors located to code can still produce real-world scenarios where people are trampled or injured during evacuation — an outcome no business wants on its conscience or its record. Egress planning mitigates these eventualities through additional fire doors, better placement, and refined door dimensions. Corridor width and door sizing matter for more than aesthetics — in an evacuation, they can be the difference between survival and injury.

Egress planning should ideally be part of every design, providing civil defence authorities with demonstrable proof that safety measures meet code and hold up under real-world scenario testing. It also strengthens emergency plan creation — ensuring designated staff groups use specific exits instead of returning to desks to collect belongings. Egress planning is equally valuable for large outdoor venues, where thousands of people need to be safely managed during events — an area where ONE9 3NINE partners with global safety and security leaders.
