The Problem…

US Firefighter LODD’s continue to increase despite national efforts

starting in 2004 with the introduction of the 16 Firefighter Life Safety

Initiatives developed at the Firefighter Life Safety Summit .

LODD’s To Date:_____

US LODD’s Past Decade

Why???

Top 3 Killers of Firefighters #1 Cardiac/Stress/Over-exertion (Approx 48%)

#2 Traffic Accidents…Responding to and returning from alarms…excessive speed, lack of seatbelt use, failure to stop at controlled intersections. (Approx 31%)

#3 Failure to know or react to hostile fire events .i.e., Approaching flashover or backdraft conditions, Collapse, Failure to understand changing fire conditions…smoke resulting in Firefighter Disorientation. (Approx 21%)

Top 3 Firefighter Killers

48%

21%

31%

Again….Why?

A culture change is needed…

Complacency

Competency

Cockiness

Things will not get better until there is a culture change…

Terminology Open vs. Enclosed Structure: An enclosed

structure is a structure where there is an absence of useable doors and windows of sufficient size and number to provide prompt ventilation and emergency evacuation…This include s basements.

Enclosed structures are highly prone to produce life threatening hazards & are directly linked to LODD’s

These structures exist in tremendous numbers, in every community, and can be of any size, type, age, and occupancy. They can be occupied, unoccupied or vacant.

What type of structure do we fight most of our fires in?

Open Residential Structures…

Enclosed Structures can be any size, any age, or any occupancy… and they’re found in all

communities

The Enclosed Structure is a specific and extremely dangerous type of

structure and is killing firefighters at a disproportionate rate in multiple

ways… Floor/Roof Collapse Falls through fire-weakened floors Disorientation Depletion of Air Supply Flashover Backdraft

12/99 Worcester, MA 6 Firefighters Killed

Charleston 6/18/07

Why is this continuing to happen?

The problem…One common problem cited in

firefighter fatality investigations is:

Failure to Follow or Adopt Standard Operating Procedures/Guidelines

The Problem… The US Firefighter Disorientation

Study published in 2003 (Mora) found that many of the SOP’s in use at the

time of the LODD were actually ineffective, unsafe, or needed

operational revision.

Terminology Prolonged Zero Visibility: Heavy

smoke conditions lasting longer than 15 minutes.

Why 15 Minutes?

Do you know your air consumption rate?

Lessons LearnedMora’s 2003 US Firefighter Disorientation Study

spanned 22 years of LODD data from 1979-2001 & included 17 case studies.

The study found:

Enclosed Structures are directly linked to Firefighter Disorientation

In 100% of the cases studied when a fast, aggressive interior attack was used at enclosed structures, firefighter disorientation occurred 100% of the time in which a LODD or serious F/F injuries were involved.

Lessons Learned Mora’s 2nd Study-The Analysis of

Structural Firefighter Fatality Database 2007 (1990-2006) found:

444 LODD occurred; 176 were structure fires

77% occurred in Enclosed Structures where a fast aggressive interior attack was utilized

The Disorientation Sequence Prolonged Zero Visibility Conditions Exist

Hoseline Separation/Entanglement Encountered

Disorientation Occurs followed by depilation of air supply. F/F caught in flashover/backdraft conditions or structural collapse occurs… Resulting in Serious Injury or Death

Why is this… being repeated?

A few of the lesson learned from Charleston:

Culture Change needed Competency, complacency Risk Assessment Construction type dangers Enclosed structure dangers Code Enforcement Preplanning Utilize latest technology

Lessons LearnedThe fire service’s lack of knowledge about the extreme dangers posed by

the enclosed structure and the disorientation sequence.

Add to this… the failure to recognize or react to the dangers of lightweight construction, pre-flashover & backdraft warning signs…Misinterpreting size-up

Failure to Manage the Risk…

Lessons LearnedWhen the downed Firefighter is not

quickly located serious injury or death results.

RIC on scene & ready? Minimum of 90 seconds before RIC can enter… Trapped firefighter usually not found until 3rd or

4th attempt. Do you have adequate staffing on-scene? Do you know your Air Consumption Rate?

Proposed Risk Management Solutions

Firefighters must be warned about the extreme dangers enclosed structures present and that an aggressive interior attack immediately upon arrival may be ineffective and unsafe in many cases.

SOP/SOG’s must be re-written adopting new tactics and strategies for enclosed structures, lightweight construction, & basement fires, etc.

Solutions The SOP/SOG must call for the

utilization of a Cautious Interior Assessment (CIA) instead of the traditional quick hit.

Quick Access Pre-Fire Plans must be developed for high-risk structures

Officers must routinely integrate risk management into operations

Officers must Integrate Risk Management by:

Using sound officer judgment at every structure fire to include:

Conduct Risk vs. Benefit Analysis SOG/SOP’s must include a Defensive Fire

Attack policy on structures that are fully involved, or where there is nothing left to save. Similarly, a primary search is not initiated.

This policy must include abandoned, vacant, or dilapidated structures that are either partially or well involved.

Risk Management Techniques

Routinely assign Incident Scene Safety Officer at all enclosed structures

Determine if basement is involved Utilize Thermal Imager Cut inspection holes in floor if

needed Communicate information to crews Attack fire from safe positions Conduct Cautious Interior

Assessment (CIA) at enclosed structures

Cautious Interior Assessment

The CIA is a process whereby:1. First arriving engine company enters

the structure with: a. Thermal Imager b. Charged handline (w/ an

established water supply) c. Backup crew To look into the structure and locate

the seat of the fire.

Cautious Interior Assessment

2. After the seat of the fire is located the officer makes the decision to:

a. Make an aggressive interior attack and call for additional resources, or

b. Make a Short Interior Attack (SIA) or

c. Go Defensive

Short Interior Attack An SIA involves advancing handlines

to the seat of the fire via the shortest distance possible by using existing windows, doors, or by breaching techniques.

Benefits of the SIA Increases Firefighter Safety by

minimizing the distance between the outside and the seat of the fire.

It maximizes Firefighter’s Air Supply Prevents handline separation &

disorientation Helps avoid exposure to

flashover/backdraft and collapse conditions.

More Solutions…. A Disorientation course must be

provided to all firefighters

Officers must be able to quickly identify an enclosed structure upon arrival and implement an Enclosed Structure SOP

More Solutions… Fire Departments must be advised

that live fire training in acquired structures that are enclosed must be avoided.

FD Inspections must insure the operational status of sprinkler and other suppression and detection systems in enclosed buildings.

More Solutions… Fire Departments should develop a

list of Enclosed Structures in their communities with the addresses

This information should then be provided to the dispatch center for immediate dissemination in the event of an alarm that address via CAD to Mobile Data Terminals in responding fire apparatus or via radio traffic.

Not for a piece of property… Firefighters traditionally serve our

communities exceedingly well and save lives and structures that can be saved. However, firefighters can no longer needlessly place their lives in extreme danger for a piece of property.

Closing Thoughts… The firefighters who have died in enclosed

structures over the past decades did precisely what they were trained, ordered, and expected to do…they implemented widely accepted tactics and strategies that have worked for them throughout their careers…

However, as long as we continue to fight fires in enclosed structures the traditional way, with complete confidence, by the book, from the unburned side, using a fast and aggressive interior attack…we will continue to die.

The Times They are a Changin’…

If your department routinely implements a fast & aggressive interior attack without following a risk management statement and is not aware of the dangers associated with enclosed, abandoned, vacant, or dilapidated structures or maintained structures that cannot be saved, your firefighters run a high risk of serious injury or fatality.

In the future, the high percentage of firefighter LODD’s will only be reduced if local, progressive leadership institutes tactical changes more appropriate to managing today’s risk.

It takes a Tactical & Cultural Change to Prevent LODDs

“What were trying to do is change the culture of the fire service. It’s no longer acceptable to put your life on the line for a piece of property. Yes, we’re going to save lives and we’re going to put our lives on the line to save someone else. But stop and think what your doing before you go into a burning building”

David Paulison, Former USFA Administrator“To prevent the tragic loss of firefighters the safety culture

must change. In this effort, Firefighters must understand that they are not required to sacrifice their lives to save any structure, regardless the type of occupancy encountered including residences, churches, restaurants, and even high rise buildings.”

Captain William Mora (Ret) San Antonio Fire Department

Firefighters… Stay together Avoid complacency Be a Leader Educate yourself and continue to do so If you see a problem take action to fix it Take ownership of this culture and change it Have the courage to be safe Stay Fit Drive Safe Tactics-Tactics-Tactics Make everyday a training day Your #1 Priority…Go home at the end of the day

Fire Officers…

Your #1 Job is to insure Everyone Goes Home

You must be an effective competent leader You must be prepared & accountable You must be a good decision maker You must be an enforcer of policies and

procedures You must be a good role model

Nothing less than your crew’s life depends on it...

Let me challenge you with this final thought..

Firefighters-What are you doing both personally and professionally to avoid becoming a LODD statistic?

Fire Officers-What is your department doing to avoid experiencing a LODD?
