Chapter 4 FF2 Please enter your email: 1. What is the most effective defense against heavy content fuel loading? Proper inspection and code enforcement Not allowing the use of combustible materials in construction Restricting the types of combustible materials used Adopting local standards that limit multistory buildings 2. Which type of roof is used whenever large open floor spaces with limited interior support is needed? Lantern Sawtooth Mansard Bowstring truss 3.

In what fire stage is structural collapse very likely? Incipient Decay Growth Fully developed 5. Which of the following must be considered when deciding the size of a collapse zone? Number of personnel on-scene Type of building construction and safest location for personnel Number of personnel on-scene and type of building construction Local adopted building codes 6. Vertical tactical ventilation can be defined as channeling smoke from the: point in a building that has the most windows. point in a building that has the least windows. lowest point in a building. highest point in a building. 7. Which of the following BEST describes a primary dangerous building condition? Conditions that contribute to fire spread Conditions that suppress fire Conditions that permit occupants to safely escape Conditions that allow tactical ventilation 8. For which type of construction is flying glass the primary collapse zone hazard concern? Type V Type III Type I Type IV 9. Fuel loading is defined as the maximum heat produced if: nothing but combustible materials are present. no combustible materials are present. all combustible materials in a given area burn. none of the combustible materials in a given area burn. 10. Which of the following BEST describes where the collapse zone is established? Near any area that is 20 feet (6.09 m) from exterior walls Near any area that is 10 feet (3.04 m) from exterior walls Adjacent to any exposed exterior walls Adjacent to any exposed interior walls 11. The critical temperature for steel trusses is: 900°F (482°C). 500°F (260°C). 1,000°F (538°C) 300°F (149°C). 12. When exposed to temperatures above ___ unprotected steel will expand and twist. 900°F (482°C) 500°F (260°C) 1,000°F (538°C) 300°F (149°C) 13. Which of the following BEST describes when structural collapse may occur? It can occur well after the fire is extinguished. It can only occur before fire suppression. It can occur when all the factors are met. It can only occur during fire suppression. 14. A collapse zone must be established when: there is no evidence of structural instability. furnishings and finishes do not overwhelm fire suppression systems. a defensive strategy has been adopted. mortar between masonry shows no sign of deterioration. 15. Knowing types of doors and door hardware can help firefighters: predict fire development. judge roof safety. select the right type of vertical tactical ventilation. select correct forcible entry tools. 16. When a collapse is imminent, personnel ___ in the collapse zone. should never work may cautiously place an unstaffed master stream are allowed to work may stay for twenty minutes 17. Renovation, age of the structure, weather, and loads are all: impossible to estimate the impact of on a structure. structural collapse factors. renovations hazards. building construction hazards. 18. A collapse zone for a Type IV structure should be established when: walls begin to shift because the building is twisting. its veneer begins to curtain collapse. it has been determined that glass shards will be directed at on-scene personnel. the structure has been weakened by repeated fires over time. 19. Which of the following BEST describes a possible construction hazard? The building is subject to rapid fire spread because protective features are not in place. Furnishings may contribute to fire spread. Danger increases because occupants and belongings remain in one part of the building while work goes on in the other. Fire detection systems may be damaged.
