Addressing Public Expectations - Meet or change?

Duty to the citizens we serve is frequently held up as our most basic and sacred responsibility as firefighters, and I couldn't agree more. It motivates us to perfect our skills for the benefit of others, face dangers known and unknown, and even to leave a warm bed to assist a stranger. In short, it inspires selflessness. Still, though that obligation is powerful, it is unfocused; it serves as a compass, not a map. My point in making this distinction is to counter the frequent citation of…

Interior Search - Flipping the Survivability Question

The practice of estimating the likelihood of finding living persons inside a burning building, and basing a large part of our risk determination on this calculation - more specifically, the decision whether to enter the building to perform a search - has spawned fervent discussions in the fire service, to say the least.  One side cites the lack of justification for risking firefighters’ lives if it is unlikely there is anyone alive to rescue,…

Inching Closer to Agreement

I'm going to end 2018/start 2019 with a positive assessment of the past year's progress spreading the new fire dynamics knowledge and integrating it into our tactics. To be sure, this may be an overly optimistic view, as sometimes there seems to be more than enough distance between the two sides to take an entire fire service career before they meet somewhere near the center. Still, I have been seeing and hearing more and more evidence of the spread of our evolving understanding of…

Priorities and Tactics - Apples and Oranges

When engaged in an activity where seconds count, lives hang in the balance, and there is little margin for error, choosing the correct initial action is critical.  As firefighters, we must "get it right" the first time, and there are no “do overs”.  To be most successful in protecting lives and property, our selection of methods and their execution must be flawless.…

Fastest Water Wins

Everybody knows you need water to control fire. (And, by “everybody”, I mean firefighters, scientists, politicians, civilians, immigrants, elementary school children, your spouse and kids. Everybody.) That’s why fire apparatus are primarily designed around the need to quickly transport water to the location of a fire, engineered as they are with the capacity to carry a booster tank, hose, pump, appliances, and the personnel needed to put it all to work. It didn’t take a series of high-tech…

You Can't Scare Firefighters

Fear is a lousy motivator for persons who have joined an organization that routinely confronts danger, especially when, for some, that danger was itself a motivator to join. Now, I am not suggesting that firefighters care less about themselves than your average citizen; just that they generally put the wellbeing of others ahead of themselves. This helps them face hazards that, without such a focus, would cause your average human to turn - if not run - away. Of course, we are also trained and…

“I” is for Ventilation - Using all available tools for controlling combustion

Contrary to the action-oriented, fix-it, can-do attitude of firefighters that make us so effective in most fire suppression and rescue situations, sometimes the best thing we can do to protect the lives and property of those we are sworn to serve is let some things alone. What makes this “hands-off” approach even more difficult is that the tactic I am here addressing - Ventilation - is one that we had been taught and believed was not only helpful and necessary, but a priority for…

Water Rules: Summary of the recent UL Studies Part 3: Full Scale Experiments - Findings

We have come to the point in this series that we will be looking at the results of the type of experiments the fire service has been clamoring for since UL and NIST first began releasing findings from their fire dynamics research that challenged longstanding practices. (To be fair, only some members of the fire service wanted these additional studies, in large part to address the concerns of other members who didn’t think the previous tests…

Water Rules - Summaries of the recent UL studies Part 1 - Water Mapping

The nozzle is the fire service’s iconic and essential tool, like the rifle to the soldier, the hammer to the carpenter, or the knife to the chef. While we have many other tools, and vital roles that don’t even involve water, when on the fireground most of them support or depend upon use of this appliance. Forcible entry clears its way, and ventilation clears its results. The protection of life and property relies on its expert use, and salvage protects the building and contents from the…

Vertical Ventilation Video - What do your eyes tell you?

The following video clip was sent to me by a reader who was responding to my last post regarding vertical ventilation:

https://youtu.be/iK-ZpPWJIj4

In it, you will see two firefighters vigorously cutting a roof as fire burns below. The provider of this link pointed out the immediate improvement in interior conditions as evidenced by the lift in the smoke layer that occurred as the fire vented. Taking a contrary position, I would point out…

Cutting Roofs - Our beloved, dangerous waste of effort

I generated a bit of discussion a few years ago when I posted a blog expressing my viewpoint that vertical ventilation, except in the presence of pre-made openings (rooftop scuttles or bulkhead doors) was a tactic that had little utility on the modern fireground (http://community.fireengineering.com/profiles/blog/show?id=1219672%3ABlogPost%3A620250). This was based on our then-new knowledge…

Inciting Bravery - The realities of promoting risk-taking; Part 4: Summary

My inspirations for starting this series investigating the feasibility of increasing firefighters' danger tolerance included the suggestion that the modern fire attack (MFA) technique of exterior streams was evidence of cowardice, as well as recent rants regarding firefighters “not doing their jobs”, at least as defined by the person posting the rant, which generally involve the perceived hesitation of other firefighters to perform interior operations. To me, the idea that we all merely need…

Inciting Bravery - The realities of promoting risk-taking; Part 3 - Should we increase it?

So far in this series exploring the practical limitations inherent in any attempt to motivate firefighters to think less about their own safety and more about the lives and property we are sworn to protect; to display more boldness and less caution, I have suggested that the concept of heroism is so vague as to render it virtually useless as a tool for either change or measurement, and have proposed that the route to maximizing effort is to educate, demonstrate, and support the desired…

Inciting Bravery, Part 2 - The realities of promoting risk-taking - Can we increase it?

Having cited the limitations and contradictions of the concept of heroism in my last post (i.e., unmeasurable, and essentially bestowed upon all of us simply for joining the fire service), is there another attribute that might allow us to be more effective in our attempts to protect life and property by inspiring bolder searches and fire attacks? Might it be feasible to at least increase our collective acceptance of risk? And, if so, what would be the best method for accomplishing this…

Inciting Bravery - The realities of promoting risk-taking

Part 1 - What are we talking about?

Courage is considered by most to be a vital firefighter trait, and its lack has been cited by some as the cause of a decline in fire service effectiveness. Whether it's a perceived pre-occupation with safety, or a choice of fire control tactics that are considered less valiant, the willingness of our members to display sufficient bravery in the pursuit of protecting life and property has been called into question. Unfortunately, an…

Results of UL Fire Attack Studies Published

Underwriters Laboratories Firefighter Safety Research Institute (ULFSRI) last week released their three reports on the Fire Attack Study - Water Mapping, Air Entrainment, and Full Scale Experiments. They can be accessed from the Fire Engineering home page, or at www.ulfirefightersafety.org. These were the experiments that looked at the effects of interior attack, among other things, in order to provide more realistic comparisons amongst…

Cowards and Morons - Seeing past labels

Sticks and Stones/Axes and Halligans. Firefighters have the means to put a serious hurt on somebody, but we use our tools instead for good. Our words, on the other hand, are wielded, at least by some, with much less regard for the human damage they can inflict. The internet has proven itself fertile ground for zingers and put-downs, allowing a well-timed and -phrased comment to create a virtual worldwide chain-reaction of effects, which can be amusing and/or hurtful, depending upon the…

Divisions and Distractions - Exploring hot-button topics

I stirred up more than a little controversy recently when I questioned the feasibility of increasing our effectiveness by decreasing our caution (See "Worth Dying For?!" at http://community.fireengineering.com/profiles/blog/show?xg_source=activity&id=1219672%3ABlogPost%3A641725).  Many who contacted me were supportive and encouraging, with some describing…
