質問 # 14
What type of property classifications experience the majority of fire deaths in the United States?
- A. One- and two-family dwellings
- B. Educational
- C. Public Assembly
- D. Business
正解：A
解説：
Explanation
The type of property classifications that experience the majority of fire deaths in the United States areone- and two-family dwellings.According to the NFPA, one- and two-family dwellings accounted for 64 percent of all civilian fire deaths in 2021, followed by apartments with 11 percent, and other residential properties with 1 percent1.One- and two-family dwellings are more vulnerable to fire fatalities because they often lack adequate fire protection systems, such as smoke alarms and sprinklers, and havemore potential sources of ignition, such as cooking, heating, and smoking2. Additionally, one- and two-family dwellings may have less escape routes, longer response times, and more occupants, especially children and elderly, who are at higher risk of fire death.References:

質問 # 15
Which type of fire alarm system transmits signals that are permanently recorded at a constantly attended supervising station located either at the protected premises or at another location of the property owner?
- A. Proprietary
- B. Auxiliary
- C. Remote station
- D. Central station
正解：A
解説：
Explanation
A proprietary fire alarm system is a type of fire alarm system that transmits signals that are permanently recorded at a constantly attended supervising station located either at the protected premises or at another location of the property owner. A proprietary fire alarm system is owned and operated by the property owner or the owner's agent. A proprietary fire alarm system is intended to provide fire alarm service to a single property or a campus of related properties.References:

質問 # 16
Which of the following would NOT be an appropriate purpose for employing a guard service to protect a property against fire loss?
- A. To carry out procedures for the orderly conduct of some operations on the property
- B. To protect the property at times when the management is not present
- C. To perform routine housekeeping and equipment maintenance operations during nonproduction hours
- D. To facilitate and control the movement of persons into, out of, and within the property
正解：C
解説：
Explanation
The correct answer is C. To perform routine housekeeping and equipment maintenance operations during nonproduction hours would NOT be an appropriate purpose for employing a guard service to protect a property against fire loss. A guard service is typically hired to provide security and protection for a property, not to perform other tasks that are unrelated to fire prevention or control. Housekeeping and equipment maintenance operations should be done by qualified and authorized personnel who are trained and equipped to handle any potential fire hazards. A guard service may not have the necessary skills, tools, or authority to perform these operations safely and effectively.Moreover, these operations may interfere with the guard service's primary duty of monitoring and patrolling the property for any signs of fire or intrusion12345
質問 # 17
For either a grain dust fire or explosion to occur and be sustained, which of the following elements must be present?
- A. Fuel, ignition source, oxygen, and combustible dust
- B. Fuel, oxygen, confinement, and ignition source
- C. Fuel, ignition source, and oxygen
- D. Dust, heat, and ignition source
正解：A
解説：
A dust explosion is the rapid combustion of fine particles suspended in the air, often but not always in an enclosed location. Dust explosions can occur where any dispersed powdered combustible material is present in high enough concentrations in the atmosphere or other oxidizing gaseous medium such as oxygen.
Dust explosions are a frequent hazard in underground coal mines, in grain elevators, and other industrial environments. On the other hand, they are also commonly used by special effects artists, filmmakers, and pyro technicians, given their spectacular appearance and ability to be safely contained under certain carefully controlled conditions.
Conditions required
There are four necessary conditions for a dust explosion
* A combustible dust
* The dust is suspended in the air at a sufficiently high concentration
* There is an oxidant (typically atmospheric oxygen)
* There is an ignition source
In some traditional analyses of dust explosions, confinement is considered to be a fifth requirement; this is not an essential condition, but can greatly aggravate the physical damage that results.
How do combustible dust explosions happen?
Any fire needs three elements. These elements are known as the "fire triangle":
1. Fuel to burn
2. Oxygen
3. Ignition source (heat, spark, etc.)
A dust explosion needs two additional elements - known as the "dust pentagon":
4. Dispersion of dust particles in the right concentration, and
5. Confinement of the dust cloud.
Dispersion means the dust particles are suspended in air. Confinement means the dust is in an enclosed or limited space. This restriction allows pressure to build up, increasing the likelihood of an explosion.
Figure shows the dust explosion pentagon. Figure from Occupational Safety and Health Administration (OSHA).
質問 # 18
Which of the following is the correct UL classification of roof covering that include criteria for resistance to ignition?

質問 # 19
What are the human health effects of exposure for two minutes at a concentration of less than 50 ppm of hydrogen fluoride?
- A. Slight eye and nasal irritation.
- B. Mild eye and upper respiratory tract irritation.
- C. Moderate eye and upper respiratory tract irritation.
- D. Moderate irritation of all body surfaces.
正解：B
解説：
Explanation
According to the CDC, exposure to hydrogen fluoride at concentrations of less than 50 ppm for two minutes may cause mild eye and upper respiratory tract irritation. The severity of the effects depends on the concentration, duration, and route of exposure, as well as the individual's susceptibility. Higher concentrations or longer exposures can cause more serious health effects, such as pulmonary edema, skin burns, or systemic toxicity.References:CDC | Facts About Hydrogen Fluoride (Hydrofluoric Acid); [Hydrogen Fluoride (HF) | Medical Management Guidelines | Toxic Substance Portal | ATSDR]2; [Hydrogen Fluoride and Hydrofluoric Acid (HF) - GOV.UK]3.

What is the background color used from the source to the outlets of a nitrous oxide medical gas system?
- A. Blue
- B. Yellow
- C. Black
- D. Gray/black
正解：A
解説：
Explanation
The background color used from the source to the outlets of a nitrous oxide medical gas system is blue. This is the standard color coding for nitrous oxide cylinders and pipelines in medical gas pipeline systems12. The color coding helps to identify the gas type and prevent accidental misconnections or cross-contamination3. The color coding also indicates the pressure and flow characteristics of the gas system4. References:
