Incident Safety Officer Complete Study Guide |
100% Correct Answers | Verified 2024 Version
Ch 5. 1.What are three things that need to be acquired to front-load for the ISO function? - ✔✔
1. NFPA 1021: standard on fire officer professional qualifications
2. Additional knowledge and skills
3. Certain attitude
Ch 5. 2.Discuss the concept of mastery and it's benefit to the ISO. - ✔✔Mastery: 90/90 rule - 90%
objective 90% of the time. Ability to perform with a certain unconscious competence. ISO needs to
address important issues with a wealth of knowledge.
Ch 5. 3.How are efficiency and effectiveness different? - ✔✔Effectiveness: doing the right things.
Learning part.
Efficiency: doing things right - performance part.
Ch 5. 4.What is the essential difference between learning and performance. - ✔✔Learning: is the
aquisition of knowledge, skills
Performance: demonstration of aquired knowlege and skills
Ch 5. 5.Describe the relationship among knowledge, skill, and attitude. - ✔✔Knowledge: bring
knowledge into application without supervision. Recognize situations
Skills: intellectual tasks such as hazard reduction, and problem solving. Determine, predict, implement
Attitude: gain knowledge and skills to shape an attitude that supports the reduction of injury and death
Ch 5. 6.To check your attitude, what three questions can be asked of yourself? - ✔✔1. What do I know
about this?
2. How do I feel about it?
3. How should I handle it to show a concern for safety?
,Ch 6. 1.What are the three ways loads are imposed on materials? - ✔✔1. Axial load: on the beam
2. Eccentric load: middle of deck
3. Torsion load: sides of deck, take twisted torsion
Ch 6. 2.List three types of forces created when loads are imposed on materials. - ✔✔1. Compression:
push both sides on a beam
2. Tension: pulls on a structural member
3. Shear: load transferee to another structure member
Ch 6. 3.What is the definition of a beam? - ✔✔A structural element that delivers loads perpendicularly to
it's imposed load is called a beam.
Ch 6. 4.Explain the effects of fire on steel structural elements. - ✔✔Cold drawn steel loses 55% at 800F
Extruded steel loses 50% at 1100F
At 1000F steel elongates 10 inches
Ch 6. 5.How does a masonry wall achieve strength? - ✔✔Compressive strength using motar. No tensil or
shear strength.
Ch 6. 6.List and define the five common types of building construction. - ✔✔Type 1: Fire-Resistive,
approved noncombustable, concrete encased steel, monolithic poured cement, steel spray on fire
protection. Large multiple-story-hard to fight rely on no collapse.
Type 2: Noncombustible, less rating-steel not coated makes for collapse. Warehouses, small arenas,
newer churches. Building do not burn but heat causes collapse.
Type 3: Ordinary, load bearing walls noncombustable masonry with wood floors, ceilings, structure
members. Taxpayer, now strip malls. Spreaders-void spaces.
Type 4: Heavy Timber, masonary exterior walls with 8"" wood laminated beams for structure, floor, roof.
Warehouses, older churches, manufactoring.
Type 5: Wood frame, new homes, small business, chain hotels built with wood.
, Ch 6. 7.What is a hybrid building? List several types. - ✔✔Combine 2 types of construction. Expect rapid
collapse due to low mass high surface to mass exposure of structural elements.
Ch 6. 8.List in order, the five step analytical approach to predicting building collapse. - ✔✔1. Classify the
construction type
2. Determine structural involvement
3. Visualize and trace loads
4. Evaluate time
5. Predict and communicate collapse potential
Ch 6. 9.List several factors that accelerate the time that a structural element will fail under fire
conditions. - ✔✔1. Lighter structural elements
2. Heavier imposed load
3. No time window for construction
4. Brown dark smoke light weight times up
5. Gravity and time are constant, resistance is not
Ch 7. 1.What is smoke? - ✔✔The products of incomplete combustion that includes an aggregate of
solids, areosols, and fire gases that are toxic, flammable, and volatile.
Ch 7. 2.List common hostile fire events and their associated warning signs. - ✔✔Flashover: turbulent
smoke flow, rollover, autoignition outside.
Backdraft: yellowish gray smoke, bowing black stained windows, signs of extreme heat on outside.
Smoke explosion: smoke trapped above fire, signs of growing fire, pressurizing.
Rapid fire spread: increase in smoke spread, smoke flowing from hallways faster than firefighter can
move.
Ch 7. 3.What are the four attributes of smoke? - ✔✔1. Volume: sets stage for offgassing in a given space.
2. Velocity: speed, means pressure. Heat or smoke volume. Box cannot absorb any more heat-precussor
to flashover.
3. Density: thickness, how much fuel laden in the smoke.
