be used to reduce the frequency of false
alarms, and specialized notification
approaches including positive alarm
sequences can further reduce inadvertent public notification. However, these
systems will only be effective when they
are implemented within a response plan
that accounts for human behavior.
Employees are critical for influencing
public behavior. The general public will
tend to seek validation for ambiguous
cues, and even not-so-ambiguous cues.
If employees don't respond properly, the
general public probably won't, either.
Employees, including contractors and
tenants, need to have clearly defined
roles and the facility management needs
to hold them accountable for performing
those roles.
Fires are not the only emergencies.
Public assembly areas need to consider a
variety of threats, including active shooters, bomb threats, and severe weather,
just to name a few. The desired response,
both from employees and the public,
may be different for each emergency.
Heightened awareness of mass shooting events prompted mass evacuation
of several terminals at the Los Angeles
International Airport in August 2016 and
New York's Penn Station in April 2017
due to loud noises that were perceived
as gunshots. Some facilities, including
airports, have security and operational
concerns-including screening for weapons, controlling admission, preventing
shoplifting, and others-that can create
major logistical challenges during an
evacuation. Employees and responders
should be trained to respond appropriately in each situation.
Even the best safety system will fail if
people have been conditioned to respond
inappropriately or not at all. By considering human behavior in the design of life
safety systems, we can help ensure that
fire alarm and emergency communication systems don't become boxes on the
wall that offer nothing but a false sense
of security.
