質問 # 140
Computers and other information technology equipment are particularly susceptible to
- A. light, hoselines, and airborn dust.
- B. foam, metal powders, and dry chemicals.
- C. special extinguishing agents.
- D. heat, steam, and combustion products.
正解：D
解説：
Explanation
Computers and other information technology equipment are particularly susceptible to heat, steam, and combustion products, which can damage their sensitive components, cause data loss or corruption, and impair their functionality.Therefore, fire protection for IT equipment should consider the potential sources of heat, steam, and combustion products, such as electrical faults, flammable liquids, dust accumulation, water-based sprinklers, or smoke from adjacent areas, and implement appropriate measures to prevent, detect, and suppress fires, as well as to minimize the exposure of IT equipment to these hazards1234.References:Standard for the Fire Protection of Information Technology Equipment;Fire Protection of Computer Rooms-Legal Obligations and Best Practices - ISACA;Exploring Requirements for Information Technology Equipment;Demystifying IT room protection requirements - Consulting.
質問 # 141
Fire pump overload point is defined as:
- A. 150 percent rated flow capacity at 100 percent rate total head.
- B. 150 percent rated flow capacity at 65 percent rate total head.
- C. 100 percent rated flow capacity at 100 percent rate total head.
- D. 100 percent rated flow capacity at 65 percent rate total head.
正解：A
解説：
Fire pumps are required to produce specific flow rates (GPM) and pressures of 40 PSI or greater.
Further, the above-mentioned agencies advise that the pumps should produce at least 65% of that pressure at 150% of the rated flow -- and all the while operating at a 15 foot lift condition. The performance curves must be such that the shut-off head, or "churn," is from 101% to 140% of the rated head, depending upon the agency's definition of the term.
質問 # 142
The primary design approach to mitigate the effect of wind on smoke movement in high-rise buildings is based on
- A. outside temperature.
- B. tightness of the building.
- C. fire department access.
- D. height of the building.
正解：B
質問 # 143
Under what circumstances are alpha particles the most harmful to the human body?
- A. When they are ingested or inhaled
- B. When the skin is wet
- C. When the emanating source is wet
- D. When the victim has no shielding other than clothing
正解：A
質問 # 144
Which pure metal in its solid form in oxygen has the highest ignition temperature in degrees Fahrenheit?
- A. Aluminum
- B. Titanium
- C. Potassium
- D. Zirconium
正解：B
解説：
Explanation
According to the web search results, titanium is the pure metal in its solid form in oxygen that has the highest ignition temperature in degrees Fahrenheit.The spontaneous-ignition temperature of titanium in the solid phase (below melting) is about 3020°F (1660°C)1.Aluminum, potassium, and zirconium have lower ignition temperatures in the solid phase, ranging from 1292°F (700°C) to 1652°F (900°C)23.References:

- B. 300 ft (91 m)
- C. 400 ft (122 m)
- D. 350 ft (107 m)
正解：A

質問 # 146
The ratio of the weight of a solid or a liquid substance to the weight of an equal volume of water is referred to as
- A. specific density.
- B. relative density.
- C. relative humidity.
- D. specific gravity.
正解：D
解説：
Explanation
The ratio of the weight of a solid or a liquid substance to the weight of an equal volume of water is referred to asspecific gravity. Specific gravity is a dimensionless quantity that is defined as the ratio of the density of a substance to the density of the water at a specified temperature.The density of water at 4 0C is commonly used as a reference point1. Specific gravity can be calculated using the following formula:
SG=fracrhosubstancerhoH2O
where rhosubstance is the density of the substance and rhoH2O is the density of water. Specific gravity can be used to compare the relative densities of different substances and to determinewhether a substance will sink or float in water.A substance with a specific gravity less than 1 will float in water, while a substance with a specific gravity greater than 1 will sink in water2.
For example, the specific gravity of gold is 19.3, which means that gold is 19.3 times denser than water.
Therefore, gold will sink in water. The specific gravity of ice is 0.92, which means that ice is 0.92 times denser than water. Therefore, ice will float in water.

The Class of an unstable reactive gas that readily undergoes violent chemical change at elevated temperatures and pressures is
- A. 0
- B. 1
- C. 2
- D. 3
正解：B
解説：
Explanation
Class 3 unstable reactive gas is defined as a material that in itself is capable of detonation or explosive decomposition or reaction at normal temperatures and pressures with a strong initiating source or if heated under confinement. This class of gas readily undergoes violent chemical change at elevated temperatures and pressures.
