Why We Need
Codes Codes are
said to be living documents because modern codes undergo constant
changes. New developments in construction techniques are one cause of
code changes. New advancements in construction methods are usually
first allowed under the alternative methods of construction provisions of
the code. New techniques or products go through a third party
evaluation process that evaluates the scope of a new method, product
or procedure, including its limitations. As they become more widely
used and commonplace, their limitations or expanded use become more
exposed and it is incorporated into the code with specific regulations.
The modern codes generally go through a continuous three year
development cycle, ensuring the codes "modernization". There
are exceptions to this in some codes and standards, for instance NFPA
may have irregular year code cycles, usually because of a complete
reorganization of the particular code or standard and time limitations of
the committees involved in the code or standard writing
process. This was not
always the case. Codes were once considered impediments to progress
because they changed infrequently and did not keep pace with new
developments in construction, including the re-invention of portland
cement, the change from cast iron to steel framed buildings, and the
invention of the elevator, which made the construction of tall buildings
feasible. Tragedies and catastrophic events also change the codes,
sometimes resulting in rather knee jerk reactions largely caused by
unforeseen situations. These are some of the horrific events in history
that have shaped the codes we use today: Hotel Fires MGM Grand Fire in Las Vegas (NFPA Report) 84 to
85 (conflicting reports) people died and more than 700 were
injured in this catastrophic event at the 26 story hotel in 1980. Starting
in a first floor restaurant called the Deli, it was caused by an
electrical short in a soffit. It rapidly traveled through the casino at a
rate of 15 to 19 feet per second. Wall coverings and flame spread
regulations were in place in the 1979 UBC, and these appear to have been
largely ignored in the area of fire origin (A practice that continues to
this day, witness the Station Fire, below). This disaster provided
unfortunate proof that smoke can be just as dangerous as fire. Add to that
scenario a partially sprinklered building and a largely undivided air
conditioning system common to a huge area. Then add stair towers
which were not properly constructed of fire-resistive materials, were not
provided with effective barriers for fire and smoke penetration and in
which the top and bottom doors were propped open and all doors in between
those levels were locked from the stairwell side, effectively
creating death traps for whomever entered the stairtowers, and you
have a menu for immediate code changes that exist to this day. Smoke
detector HVAC shutdown, greater protection for stair towers, greater
emphasis on field control of interior finishes and emphasis on
barriers for fire and smoke spread all evolved in the codes from this
event. Here is an interesting historical report from the Clarke County Fire Department on this fire
which includes witness statements and expert
testimony. Pioneer Hotel in Tucson with 29
Fatalities. This fire occurred in 1970. A video with pictures of the hotel in
its heyday is provided by the Tucson Historical Society. The fire was
blamed on lack of sprinklers and
alarms. Fire truck ladders could only
reach 8 stories of the 11 story building. The fire raced through the
fourth through twelfth floors, trapping many residents in their rooms and
causing many to leap to their deaths. Among the dead were the Steinfelds,
who occupied a 12ft Floor Penthouse in the hotel and had been previous
owners of the hotel for 30 years. The aftermath of the fire killed the
vitality of downtown Tucson, changing it from a vibrant destination to a
sorrowful memory of the tragedy. The hotel is not listed on the National
Register of Historic Places because of extensive remodeling after the fire
that changed it to an office-apartment building. The fire was caused by
arson, and a black teenager was convicted, but it is
doubtful whether he was anything other
than a convenient
scapegoat. Mizpah Hotel in Reno Nevada kills
12 This fire occurred in 2006
and was started by a mentally disturbed woman who worked at the primarily
residential hotel and apparently got into an argument with another
resident. She put a mattress up against the other resident's door and set
it on fire. Both of these people survived. The building was built in 1922
as the Picolini Hotel and was added to the National Register of Historic
Places in 1984. Though only three stories tall, it was large in footprint.
Constructed of unreinforced masonry with an unfinished basement of post
and beam construction, at its final configuration totaled almost 60,000
square feet. The report by the City of Reno describes mattresses stored in
the hallways feeding the fire and the hallways rapidly filling with smoke
to the floor level. Non-fire-resistive construction, lack of sprinklers
and access to exits were cited as major defects in the subsequent fire
reports. The fire alarm system, though described as "dated" in the City of
Reno report, actually functioned properly and gave the first notice of the
fire. Occupants of the hotel ignored the fire alarm as it went off
frequently and was usually quickly silenced. The U.S. Fire Administration
report states the building was equipped with Class I and II
standpipe systems, but the Class I system was not available to the fire
department because of its location in the west stairwell was "compromised
by heat and heavy smoke". The Class II system, for use by building
occupants, did have a line deployed on the third floor, and the system had
been inspected in March of the same year. Modern fire departments dislike
such systems because the hose lines deteriorate and are impossible to
test. Instead, they usually adapt them for their use by requiring original
hoses be removed and adapters installed so their hoses can be
used. International
hotel fires are sometimes ignored by Americans because
they assume, correctly in many cases, that other countries do not have the
high safety standards they think we are subject to. One example
is the Quezon City Manor Hotel
Fire in 2001 that killed over
70 people, almost all of whom died from smoke inhalation rather than
burns. Poor construction, bars on the hotel room windows to prevent
burglary, no smoke alarms, no sprinklers and obstructed exits were all
cited as causes of the high death
rate. The hotel had been cited for major safety violations months
before, but the Fire Marshall's boss did nothing to enforce compliance.
China has had several major hotel fires, including the Tiantan Hotel Fire
in Harbin, which killed 33, the Yanshan Hotel in Changsa, which
killed 30 and the 1997 Shenzen Hotel Fire which killed 29. Cited
in vague news reports are blocked exits, but there are no open or third
party investigations and it is hard to verify actual conditions or causes.
A fire at the Thai Royal Jomtien Resort killed 91 people and was
investigated by NFPA. However, such a
fire as the Dupont Plaza Hotel in Puerto
Rico, which killed 97 people in 12
minutes, was not ignored by Americans or American code
writers. Not only is Puerto Rico a
territory of the United States, the hotel was originally built as a
Sheraton in early 1960's, and was famous for its olympic
sized swimming pool. Today it is known as the San Juan Marriott
Resort & Stellaris Casino, and has been recently renovated. The fire
was started by members of a union employed at the hotel, who were in
the middle of a labor dispute. They set a can of Sterno on fire in a
storage room filled with new furniture still wrapped in original
packaging, which included foam plastics and mattresses. Rapidly out of
control, it spread into the adjacent south ballroom, which had a
significant amount of combustible furnishings and interior finishes. The
ballroom flashed over in approximately 10 minutes, and the fire
exploded into a two story foyer with glass walls that separated the
ballroom from the casino, which was located on the second
floor. About two minutes later, fuel from the heavy timber ceiling in
the foyer caused the glass walls separating the casino to explode,
effectively blocking two of the main exits from the casino and creating a
wall of flame that swept the length of the casino in about twenty seconds.
It is estimated that there were 150 people in the casino at the time of
the fire. Within 14 minutes from the fire start, 84 of them were dead, all
from flames, not smoke. The only people to survive were the ones who
exited early and then a few minutes later, a few more broke wall to
ceiling glass windows above the pool side and jumped to safety from the
second floor. The Puerto Rican firefighters, called "Bomberos", exhibited
consummate bravery during the rescue attempts. Hotel guests in the
adjoining high rise tower, which was breached by smoke from the fire, were
either directed to the roof or were able to take refuge for hours on
exterior balconies. A police helicopter made repeated return trips to
remove people from the roof, while brave bomberos climbed from balcony to
balcony with ropes, rescuing stranded victims. NIST

III. Paxton Hotel Fire, Chicago, March 16,
1993: This fire in a 140 room low
income and elderly, permanent resident hotel killed 20 people, but twenty
others were reported as missing and presumably died in the fire, since
some bodies were completely incincerated. The hotel was built in the
1930's and was mixed construction. The construction features could not be
fully investigated because access for fire investigators was limited to a
small portion of the building. The fire apparently burned for 45 minutes
to an hour before the fire department arrived, and the building's fire
alarm system did not work. The fire spread through floor joist channels
into vertical wall channels that were not firestopped. There were
approximately 160 people in the hotel at the time, as all of the rooms
were full and many people had guests. Due to the permanent resident nature
of the hotel, a higher room fuel load contributed to the spread of the
fire because many residents had a greater quantity of combustible personal
possessions than normal for a transient population. Overhead lines in
the area prohibited the deployment of aerial apparatus, so firefighters
had to resort to ground ladders to rescue occupants from their rooms.
Residents on the first floor had burglary/security bars over their
windows, which firefighters had to forcibly remove, resulting in two
deaths of people they could not get to in time. Many people jumped from
their rooms to escape the flames. The hotel room doors were of wood and
were not self-closing or rated. Only a few rooms were reported to have
smoke detectors and none were ever found, due to the destruction of the
building by flames. The building was completely destroyed, and
firefighters had to back out of the building shortly after they arrived
and fight the fire solely from the exterior. Other Hotel

Dust Explosions A pet peeve of ours, this industry and the oil refining industry seem to be of the "let's kill them, then put a bandaid on it" mentality of safety operations. Profits always come ahead of employees. All of the accidents in this industry are avoidable and are inevitably caused by lack of maintenance or attention, whether it be lack of housekeeping, bearing inspection, explosion venting, process design, safety procedures - whatever, it is ALL avoidable. in fact, as Brian Edwards, director of engineering at Atlanta-based Professional Engineering, says about it: "You need a perfect storm," Edwards said. "You have to the have the right concentrations of dust in the air, you need sufficient oxygen, and you need an ignition source." So they really have to work at it to make it happen, it ain't that easy........ Chemical Safety Board releases report on three ("let's count 'em, THREE) fatality explosions at the same plant in January, March and May or 2011. Nice of them to take a month off between incidents and being merchants of death to give the remaining employees time to mourn, wasn't it?.............The Safety Board's Conclusions for key issues were (oh my, I'm Shocked!): Hazard recognition and training....... Engineering controls.........Fire codes/enforcement........and Regulatory oversight.
