質問 # 81
Which of the following was the greatest means of awareness of a fire incident by people in the United States?
- A. Saw smoke
- B. Flt heat
- C. Smelled smoke
- D. Saw fire
正解:A
解説:
Participant Population Awareness of the Fire.
The stimulus which first indicated to the participant the occurrence of the fire incident is recorded in Table XXXIV) It should be noted there were thirteen varied stimuli which tended to alert the participants as the fire incident. The most prevalent means of awareness of the fire incident, was the odor of the smoke produced by the fire incident. However, it should be noted the second most frequent means of awareness was the act of being notified by other participants of the fire incident. However, when this item of notification by others is combined with the fourth most frequent stimulus of being notified by a family member, the procedure of being notified by another person become the most prevalent means of becoming aware of the fire incident for 224 members of the participant population which was approximately 39 percent of this population. It should be noted under the third most frequent stimulus of noise, that 42 individuals were alerted by the noise of fire alarm signals or bells within the building, and the noise of other occupants moving in hallways or stairways was also mentioned frequently.
Relative to Table XXXIV, it appears the alerting actions of other individuals upon the discovery of a fire incident may be a very important mechanism. The physical variable related to the occurrence of a fire incident consisting of the odor of the smoke. The sing of the smoke or the flame, and the sensing of the heat, accounted for the initial awareness.
質問 # 82
Which chemical is classified as a pulmonary agent?
- A. Anthracite

質問 # 83
During 1999 and 2002, fires originating in mattresses and bedding accounted for what percent of fire deaths in the U.S.?
- A. 0
- B. 1
- C. 2
- D. 3
正解:B
解説:
Since 1980, home fires starting with mattresses and bedding fell 85%.
As shown in Table 1 and Figure 1, home structure fires beginning with mattresses and bedding fell 82% from a high of 61,100 in 1980 to 8,900 in 2009, the lowest point in the 30 years of data.
From 2008 to 2009, these fires fell 12%. Details collected in NFIRS 5.0 were used to derive the estimates from 1999 on. A small portion of the sharp decrease seen from 1998 to 2002 may be due to changes in NFIRS and the exclusion of confined fires from the analysis.

質問 # 86
The primary mechanism by which carbon dioxide extinguishes fire is
- A. cooling.
- B. smothering.
- C. saponification.
- D. chemical inhibition.
正解:B
解説:

smothering.
The primary mechanism by which carbon dioxide extinguishes fire is smothering, or displacing the oxygen that the fire needs to sustain combustion. Carbon dioxide is a gas that is heavier than air, so when it is released from the extinguisher, it forms a blanket over the fire and pushes away the oxygen.Without oxygen, the fire cannot continue to burn and is extinguished1234 Cooling is a secondary mechanism by which carbon dioxide extinguishes fire. Carbon dioxide is stored as a liquid under high pressure in the extinguisher, and when it is released, it expands rapidly and cools down. The cold gas absorbs heat from the fire and lowers the temperature of the fuel below its ignition point.However, cooling is not the main effect of carbon dioxide, as it is less effective than water in reducing the heat of the fire1234 Saponification and chemical inhibition are not mechanisms by which carbon dioxide extinguishes fire.
Saponification is a process by which wet chemical agents react with fats and oils to form a soapy foam that seals the surface of the fire and prevents re-ignition. Chemical inhibition is a process by which dry chemical agents interfere with the chemical chain reaction of the fire and stop the production of free radicals that propagate the combustion.These mechanisms are used by other types of fire extinguishers, such as Class K and Class D extinguishers, respectively1234 References:

質問 # 90
What is the maximum allowable quantity per control area for a nonliquified oxidizing gas stored in a gas cabinet in an unsprinklered area?
- A. 1000 ft3 (28 m3)
- B. 3000 ft3 (85 m3)
- C. 1500 ft3 (43 m3)
- D. 2000 ft3 (56 m3)
正解:D
解説:
Explanation
According to NFPA 400, Table 5.2.1.1.3, the maximum allowable quantity (MAQ) of a nonliquified oxidizing gas per control area in an unsprinklered area is 2000 ft3 (56 m3) when stored in a gas cabinet. This quantity can be increased by 100% if the area is sprinklered or by 300% if the area is also provided with a gas detection system. A gas cabinet is a ventilated enclosure for the storage of one or more compressed gas containers that provides a method of control for potential leakage or fire exposure hazards [NFPA 400,
