What is Egress?

Egress, The means of exit from a building including doors, windows, hallways, and stairways that provide safe evacuation routes

Description

Egress is the means of exit from a building including all doors, windows, hallways, stairways, and other components that provide safe evacuation routes for occupants during emergencies. These critical life safety systems must meet strict building code requirements for size, location, accessibility, and performance to ensure rapid, safe evacuation while preventing panic and overcrowding during emergency situations.

Purpose includes providing safe evacuation routes, meeting building code requirements, protecting occupant safety, and enabling emergency access. Quality egress design and installation are essential for life safety and legal compliance.

Components include exit doors for primary evacuation, egress windows for emergency escape, exit corridors for safe passage, and exit stairs for multi-story buildings. Each component must meet specific code requirements for size and performance.
