ANALYSIS OF SIGNIFICANT FACTORS
Building Construction and Contents
The combination of a light fire loading and non-combustible,
fire resistive building construction helped limit the fire
damage to the room of origin and the corridor in the immediate
vicinity. Combustible contents in the room of origin were
limited to a wood desk, two wood chairs with small seat
and/or back pads, a wood dresser, a television with stand,
drapes, and a bed. (See Figure 3.) The mattress consisted
of 30% urethane foam, 40% blended cotton felt, and 30% sisal.
(See Figure 11.) It was apparently 1 purchased only three
years ago which would indicate compliance with federal smolder
resistance standards. However, the testing for compliance
with federal standards doesn't contemplate a vertical mattress
placed against combustible curtains next to an open window.
The bedding, furniture upholstery, and window curtains were
unlabeled and probably ignited easily. The only combustible
materials in the corridor were the carpeting and decorative
wood beams on the non-combustible ceiling. The lack of rated
self-closing doors to guest rooms allowed smoke and fire
to escape into the corridor from the room of origin, and
the lack of stairway enclosures allowed smoke to spread
to the upper floors.
Fire Protection Equipment
A key factor in the successful evacuation of occupants
was the early warning provided by the smoke detector in
the room of origin. Had the fire been fully extinguished
when first detected, a major fire incident would not have
occurred; however, the early detection of the rekindle was
ultimately responsible for the escape of the room occupant,
the earlynotification of the fire department, and the evacuation
of guests. Texaspassed a law in 1983 which required all
hotels, motels, and apartments toprovide smoke detectors
to protect sleeping areas.
The fire department did experience some trouble evacuating
thebuilding due to the lack of a fire alarm system. Many
guests were unaware that there was a fire until fire department
personnel knocked on the door to evacuate them. Some actually
refused to leave until ordered to do so by police.
The lack of sprinklers and fire alarm systems placed additional
demands on the fire department to rescue occupants. The
fire department was able to gain control of the situation
due to prompt notification and fast response times. Had
sprinklers been present in the hotel's guest rooms, it appears
that the fire might well have been controlled by one sprinkler
head.
Human Behavior
Unlike the transient nature of occupants in a typical hotel,
the La Posada was occupied almost entirely by guests who
were somewhat familiar with the hotel. Eighty-five percent
of the guests were with the Federal
Deposit Insurance Corporation, and had been in the hotel
for one and a half weeks at the time of the fire. Of the
other 15 percent, many were seasonal guests who had been
residing in the hotel for an extended period. Occupant familiarity
is thought to have contributed to the large number of guests
who were able to evacuate on their own, and probably eased
the anxiety of those evacuated by the fire department in
smoky conditions. |
