4 Benefits of the Incident Safety Officer Diminishes accident potential and enhances safety culture Minimizes time lost due to injuries Helps protect against liability Maximizes Incident Commander focus Instills safety-consciousness in the Firefighters themselves Enhances efficiency and effectiveness Diminishes accident potential and enhances safety culture Minimizes time lost due to injuries Helps protect against liability Maximizes Incident Commander focus Instills safety-consciousness in the Firefighters themselves Enhances efficiency and effectiveness

5 The Nature of Firefighters Aggressive - want to get in Action oriented Results oriented Risk-takers Hot and cold influences on behavior Fatigue (post incident) Adrenaline burn – chemical imbalance? What do we know about ourselves?

6 Duties of the ISO In it’s simplest form, the ISO evaluates: Fire Behavior Building Behavior - the environment Firefighter Behavior This helps you READ the RISK!

24 SMOKE EXPLOSION Remember – A Smoke Explosion is a spark or flame applied to a mixture below its ignition temperature Trapped gases in upper areas Growing fire Increasing smoke density Air intake overtaking smoke exiting Remember – A Smoke Explosion is a spark or flame applied to a mixture below its ignition temperature Trapped gases in upper areas Growing fire Increasing smoke density Air intake overtaking smoke exiting

30
30 VOLUME Always relative to the “Box” Tells “how much” fuel has off-gased Sets the Stage Always relative to the “Box” Tells “how much” fuel has off-gased Sets the Stage
31
31 VELOCITY (Pressure) How fast is the smoke leaving? Can indicate volume or heat Helps find the location of the actual fire
32
32 DENSITY Most Important Factor Quality of Burning Continuity of Fuel Likelihood of an event “Degree” of the Event
33
33 COLOR Rarely tells “material burning Stage of Heating Location of Fire Amount of Flaming “Brown” Smoke

35 Step 3: Judge the Fire Status Are conditions getting better or worse?
36
36 Classify the Fire: Stable -predictable Rapidly changing -predictable -predictable Unstable/Unpredictable

41 The Science of Predicting Collapse The “Science of Predicting Collapse” is actually A “ 5 STEP- APPROACH” to evaluating collapse potential.

42 Methods/Types of Construction Fire Resistive Non-Combustible: Steel, concrete, masonry, glass Ordinary: Load-bearing masonry exterior wall, combustible interior construction Heavy Timber (Mill) Wood Frame: Platform, Balloon, Lightweight Hybrids? Fire Resistive Non-Combustible: Steel, concrete, masonry, glass Ordinary: Load-bearing masonry exterior wall, combustible interior construction Heavy Timber (Mill) Wood Frame: Platform, Balloon, Lightweight Hybrids?
43
43 Relationship of Mass/Fire Resistance The most prevalent reason the year 2002 fire is different than the 1980 fire! Most interior Firefighting tactics are based on a 1950’s structure! Mass = Fire Resistance The most prevalent reason the year 2002 fire is different than the 1980 fire! Most interior Firefighting tactics are based on a 1950’s structure! Mass = Fire Resistance
44
44 The 1950’s Building Most Members are in COMPRESSION Connections are “through” the materials MASS not MATH Fire Loading at 8000 BTUs per Pound
45
45 2000 & Beyond Members in TENSION Connections are surface attached MATH not MASS Fire Loading is 16,000+ BTUs #

46 Lightweight Construction Trusses Throughout Engineered Wood: Waste Wood Glued and Pressed Particles Composites Experimentation Methods
47
47 Predicting Collapse: The 5-Step Process
48
48 Step 1: Classify the Type Generalize Type of Construction FR, NC, O, HT, & WF **Hybrid** Strengths & Weaknesses Fire behavior within type Fire spread potential Hazards vs. Tactics Generalize Type of Construction FR, NC, O, HT, & WF **Hybrid** Strengths & Weaknesses Fire behavior within type Fire spread potential Hazards vs. Tactics
49
49 Step 2: Determine Structural Involvement Structural Fire or Contents Fire Connections Involved Protective Barriers Compromised Lightweight components off-gassing
50
50 STEP 3: Visualize Load Imposition Visually “Undress” the Building Bring in your Knowledge of Materials – and how they react in fire Weak Links?
51
51 Step 4: Evaluate TIME How long has the fire been burning? How long will it take to get to the fire? REMEMBER……
52
52 Step 5: Predict Collapse Sequence Visualize the collapse scenario Partial or localized? General ? Who is at most risk? Imminent or just a potential Proclaim a COLLAPSE ZONE What operation(s) needs to be altered, suspended, terminated Visualize the collapse scenario Partial or localized? General ? Who is at most risk? Imminent or just a potential Proclaim a COLLAPSE ZONE What operation(s) needs to be altered, suspended, terminated
53
53 You Now Have the Information To Predict Collapse Envision the Collapse – see it happen in your mind ZONE the Incident COMMUNICATE! Envision the Collapse – see it happen in your mind ZONE the Incident COMMUNICATE!
54
54 Once you’ve Zoned & Communicated, Remember... More FF’s are killed outside the building than in You Must understand defensive outside tactics The collapse zone - types of collapse The reach of hose streams The advantages & risks of aerial streams The collapse zone for aerial streams Flanking a fire from the safe zone More FF’s are killed outside the building than in You Must understand defensive outside tactics The collapse zone - types of collapse The reach of hose streams The advantages & risks of aerial streams The collapse zone for aerial streams Flanking a fire from the safe zone

55 Construction Sites – WATCH OUT! Under construction vs. Under fire attack Components not necessarily joined - less stable Irregular ground, holes, mud Power and water may not be functioning Walk ways and worker paths may not be secure Beware of openings between floors, ventilation shafts, etc. Under construction vs. Under fire attack Components not necessarily joined - less stable Irregular ground, holes, mud Power and water may not be functioning Walk ways and worker paths may not be secure Beware of openings between floors, ventilation shafts, etc.

62 HYDRATION AND FLUID REPLACEMENT 17 minutes of firefighting results in a 15% reduction in plasma volume. Hyperthermia causes vasodilation, an increase in vessel diameter. Vasodilation also may reduce blood pressure. Aggressive hydration. 1.7 liters of fluid to replace fluid lost during 17 minutes of firefighting. 17 minutes of firefighting results in a 15% reduction in plasma volume.

64 Triggers and Traps Triggers – Those things the ISO can do to help instill safe operations. Traps – General approaches that will render the ISO ineffective. Triggers – Those things the ISO can do to help instill safe operations. Traps – General approaches that will render the ISO ineffective.

65 TRIGGERS to Safe Operations BE VISIBLE – Display the word “Safety” like a banner
66
66 TRIGGERS to Safe Operations Lead by Example! SOFT Intervention – advice, sharing observations, humor, etc. FIRM Intervention – Stop, Alter, Suspend operations. Stern Advisories. Lead by Example!
