What is means of egress?#
Means of egress describes the continuous path people use to safely leave a building during an emergency.
It begins where an occupant is located and continues through corridors, stairs, exit doors and finally to a safe location outside the building.
Every building must provide occupants with a safe method of leaving when normal conditions no longer exist.
Why egress matters#
During a fire or emergency, occupants must be able to leave quickly and safely.
The BC Building Code includes detailed requirements intended to reduce panic, congestion and dangerous bottlenecks.
Good egress design saves lives by reducing evacuation time.
Common elements of an egress system#
Exit access corridors.
Exit stairs.
Exit doors.
Exterior exits.
Emergency lighting.
Exit signs.
Accessible routes where required.
Residential examples#
Bedrooms require compliant escape windows where applicable.
Basement suites frequently require careful review of exit paths.
Townhouses and apartment buildings may require protected exit routes depending on their design.
Commercial examples#
Restaurants, offices, retail stores and gyms may require different exit arrangements depending on occupant load.
Changing the use of a commercial unit can affect exit requirements even if very little construction is proposed.
Common permit issues#
Blocked exits.
Exit doors swinging the wrong direction.
Travel distances exceeding code limits.
Insufficient exit width.
New layouts reducing access to exits.
Key takeaway#
Means of egress is one of the core life-safety concepts of the BC Building Code.
Understanding exit requirements early in the design process helps avoid permit delays, redesigns and costly construction changes.
