The human element in fire protection engineering
What do a 3,700 acre fire in California, a 100,000 square foot warehouse fire in Texas, and the execution of a Texas man in 2004 have in common?
They were all events linked to arson and serve to show us the complicated relationship man has with fire, even with the modern day engineering tools and cutting edge analysis methods available to us.
Let me explore these three events in more detail:
Jesusita Fire; May 2009; Santa Barbara, CA

In May of 2009, a 300 foot high wall of fire burning through Santa Barbara, CA had 30,000 people running out of their city and wondering what they would return to, if anything more than an ashtray of their home’s contents. 3,700 acres were burned and it was marked as the most threatening natural disaster in the history of Santa Barbara. The cause? A campfire that got out of control from nearby marijuana growers.
40 MPH winds served to spread the fire as fast as it could towards the city. At the end of it all, 78 homes were destroyed, 29 firefighters were injured, and 15.5 million dollars were used. All from a campfire. From pot growers. This event reeks seriously of the complicated relationship between humans and fire – a relationship of utility, usefulness, crime, chaos, and control. A relationship that cannot be engineered out by even the best computational fluid dynamics code in the world.
Gallery Furniture Fire; May 2009; Houston, TX

Moving from wildland fires to warehouse fires: in May of 2009, an iconic Houston furniture warehouse burned to the ground as freeway traffic crawled by with worried onlookers in the late evening hours. After a long night of fighting the fire, the 100,000 square foot Gallery Furniture warehouse was no more and fell victim to to the 4-alarm fire. The Bureau of Alcohol, Tobacco, and Firearms stepped in and ruled the fire as arson, leading to the arrest of an employee who worked at the furniture store.
This fire hits me close to home since my Master’s thesis research involves warehouse storage and commodity fire protection and how it can be improved. I can formulate the best mathematical fire spread model for predicting fire spread along cardboard stacked to the ceiling, but will my math model account for a crazed man dumping gallons of gasoline in the warehouse and firing up a match? Absolutely not.
Willingham Residential Fire; Dec. 1991; Corsicana, TX

This last fire I’ll discuss was a residential fire in the city of Corsicana in Texas. In December of 1991, the home of Cameron Willingham was burned and his three children were killed in the fire. He was later arrested and imprisoned on the basis that he had set fire to his house and was responsible for the death of his children. The fire marshal’s investigative report backed this up. 12 years passed, and Cameron was executed in February of 2004 in Texas for murder charges.
Just a few days ago, in August of 2009, a report from Craig Beyler at Hughes Associates (one of many reports to check the validity of the fire investigations on Willingham’s residence) stated that the fire investigation seemed more like the work of psychics and mystics rather than scientific work. There are other human factors here at work – Cameron’s alleged abuse of his children is one example – but I am sticking to the discussion of the relationship between Cameron, the investigators, and fire. In the report, Beyler stated that the investigators had a poor understanding of fire science. And because of their poor understanding, a man was wrongly killed by the state.
Putting it all together: Humans, fire, and education
So the relationship of man vs. fire goes back to the first time someone discovered fire. It is very complicated. Now what? How can we use our understanding of this relationship to save lives?
While churning along my research path, I have learned that I favor fire research, fire dynamics, and fire forensics over alarm design, building construction work, or working with fire codes. The three fires that I discussed above are most interesting to me are all involving arson in some way – and humans in a big way. One fire came from clumsiness, one fire stemmed from passionate and crazed anger, and one fire put to death a wrongly accused person and killed three children. I don’t know about you, but to me, this serves to smack us fire protection engineers in the face with a reminder that the human element can never be ignored, or fully engineered out of the problem of fire. The consideration of the human element should be included in every thought, design, and fire model that is churned out.
And although a recent survey by the Society of Fire Protection Engineers showed that most people think that fire is the greatest likely event to cause harm to them, it also showed that only 18% of the respondents actually worried about the dangers of fire more than once a year. The solutions that fire protection engineering provides stem from years and years of exploring this relationship of people and fire: how crowds react in a building fire, how different residential occupants can be awoken in a fire, and how people respond to building fire alarms.
In my opinion, the best help in the impact of fire protection engineering is effective education of the public. Informing the public (in interesting and engaging ways!) about fire safety and what they can do in their homes and workplaces to stay safe. Informing college students about dorm fire safety. Moving on from stop, drop, and roll, and giving people more of the information and knowledge that they deserve. Informing residents about the benefits of fire sprinklers, and having a huge incentive to have them installed, even retroactively.
And who is responsible for all of these education efforts? Anyone and everyone in the fire protection field. From engineer to firefighter, fire librarian to professor, code official to fire marshal. Everyone can serve to help the big picture of educating the public by taking fire science courses, by working with code committees, by linking together agencies and people who need to be talking, but aren’t. Fire investigators can take fire science courses and fire scientists can run into burning buildings in training exercises. The more we know as professionals about the big picture, the more we can help and educate the public, and save lives in the process.
So again, I say that effective education of the public is the best tool in fire protection engineering. Because without an informed public, we can have the best fire models and investigators in the world, but we would only be putting a band-aid on the complex fire hose of man vs. fire.
