Occupant Protection Concepts
Evacuate
Total
Staged
Relocation to safe
area within the
building
Defend or protect
in-place
Area of Refuge
A temporary staging area that provides relative safety to its
occupants while
Potential emergencies are assessed
Decisions are made
Mitigating activities are begun
A stage between egress from the
immediately threatened area and
the evacuation of the building .
Defend/Protect In Place

How long will it take?
Complete evacuation may require a
significant amount of time
Evacuation from large buildings can be
physically exhausting
It could slow emergency responders who may
need the stairs to reach the problem
Reporting an Emergency
Time is critical
Report emergencies
rapidly
Know the procedures for
your building
Use the best available
means of communication
Your Responsibility
Keep the exits clear
No storage or other use within the exit
Do not compromise fire protection and
alarm systems
Promptly report problems with exits or
systems to building management
Protecting Yourself
Do you know how to react if you are faced
with an emergency?
Could you protect yourself and others
around you in an extraordinary event?
Self reliance – 72 Hr. response time
When all else fails, you are
ultimately responsible for your
own safety!
Protecting Yourself
1,602,000 fires – 3,675 civilian deaths –
3,105 deaths in structures, majority in
residential structures.
