Means of Egress
 Exit Access – “That portion of a means of egress that
leads to an exit.” (101)
 Exit – “That portion of a means of egress that is
separated from all other spaces of a building or
structure by construction or equipment as required to
provide a protected way of travel to the exit
discharge.” (101)
 Exit Discharge – “That portion of a means of egress
between the termination of an exit and a public way.”
(101)

Getting OUT!!
 Provide employee alarm system

Creatures of Habit – The Herd Effect
 Train evacuation assistants
 Review plan



Initially
When employee responsibility changes
When plan changes
Emergency Notification
What methods are
used to alert
occupants of an
emergency?
Emergency Messages
 What do the alarms mean?
 What actions are you expected to take?
 Who issues voice instructions?
Why should I believe the
alarm or emergency
information message?
Perception
 What is the perception of the problem?




Do employees perceive there truly is a
problem?
Do we practice what we preach?
Fire Wardens – arm band & helmet
What do other employees think?
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 .

Principles of Exit Safety
 At least two ways out
 Exits are within a reasonable travel distance
 Egress paths are
 Well marked
 Well lighted
 Unobstructed
 Evacuation training and drills provided
MEANS OF EGRESS
 Occupied Building



Open to the public
Open for general occupancy
10 or more employees present
 Door Swing


Exterior Exit Doors swing outward – direction
of egress
Room doors may swing inward – unless
occupant capacity of 50 or more
MEANS OF EGRESS
 Locking mechanisms

Key operated locks




Single Motion – Non-locking against egress



Only certain occupancies
Signs indicating door to remain unlocked
Main entrance only
Knob, lever, panic hardware
Delayed egress
Security controlled – Card Access
MEANS OF EGRESS
 Self closing – automatic closing devices
 Hold Open - electromagnetic
 Coordinators
 Astragals
 Powered Door Leaf
 Stairs
 7 X 11
 Change of direction
 Area of refuge
 Landings
MEANS OF EGRESS
 Capacity of Means of Egress



Based on Occupant Load, # of exits, etc.
Capacity factor – Health Care 0.3, 0.6, All
others 0.2
Minimum width – 36 inches
 Number of means of egress


Generally 2 minimum – remote
Single exit allowed in certain conditions
MEANS OF EGRESS
 Arrangement



“Readily accessible at all times”
Access to two different paths of travel
Room to corridor


Dead ends


Existing room to room to corridor/exit
Not permitted – except by chapter – may be 20 to
50 feet in length
Not through kitchens, closets, storage,
workroom, bedrooms, etc.
MEANS OF EGRESS
 Arrangement – con’t.
 Cannot obscure exit – curtains, hangings, art,
mirrors, etc.
 Measurement of travel distance
 Based on occupancy requirement
 Measured along path of travel
 AGPH –



75’/125’ to guest room door
100’/200’ guest room to exit
100’/150’ exit enclosure to exterior door to public
way
MEANS OF EGRESS

Industrial - General
 200 feet unsprinkled
 250 feet sprinkled
 Termination of exits
 Public way
 Exit discharge that leads to public way
 Illumination of means of egress
 Illuminate access, exit, discharge
 Stairs 10 ft. candle
 Other 1 ft. candle
 Performances 0.2 ft. candle
MEANS OF EGRESS
 Emergency Lighting





Minimum of 1 ½ hours
1 ft. candle
Automatic in the event of power loss
Emergency generator or battery pack
Testing on a regular basis



Every 30 days
Annually – 1 ½ hours
Maintain records
MEANS OF EGRESS
 Exit signs required unless “obviously and
clearly are identifiable as an exit.”

Exit signs must be illuminated






Internally or externally
Tactile signage required in new construction
Floor proximity egress path marking
Along exit access – 100 feet
Change in direction
Photoluminescent/nuclear powered signs
permitted
MEANS OF EGRESS
 NO Exit

Doors that do not lead to exit or exit access
must be labeled
 Exit Sign Testing
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.
 Fire drills in our homes


We tell ‘em good, but we don’t show them
well.
Holler at each other
 Conditioned to the same route
