Question No : 1

What percent of fire departments surveyed participate in the delivery of emergency medical services?

A.38%
B.61%
C.79%
D.90%

정답:
Explanation:
79% of fire departments surveyed participate in the delivery of emergency medical services (EMS). This is based on the NFPA report “US Fire Department Profile 2020” 1, which states that nationwide, 37% of fire departments provided no EMS, 46% provided basic life support (BLS), and 17% provided advanced life support (ALS). Therefore, the percentage of fire departments that provided either BLS or ALS is 46% + 17% = 63%. However, this does not include fire departments that provided EMS through a third-party contract or agreement. According to the NFPA fire service survey from 2018C 2020 2, 16% of fire departments reported having such an arrangement. Therefore, the percentage of fire departments that participated in the delivery of EMS in some form is 63% + 16% = 79%.

Question No : 4

For combustion to take place, a combustible material, an oxidizing agent, and an ignition source are required. The exception is

A.dielectric heating.
B.spontaneous combustion.
C.conduction transfer.
D.radiation diffusion.

정답:
Explanation:
Spontaneous combustion is the exception to the requirement of a combustible material, an oxidizing agent, and an ignition source for combustion to take place. Spontaneous combustion is a phenomenon in which a material can ignite without any external heat or flame, due to a chemical reaction within the material that generates enough heat to reach the ignition temperature. Spontaneous combustion can occur in certain materials that are prone to self-heating, such as oily rags, hay, coal, and compost. Spontaneous combustion is a type of smoldering combustion, which is a slow, low-temperature, flameless form of combustion.

Question No : 12

The two major principles used to determine egress width are the

A.density and group method.
B.flow and the capacity method.
C.inverse and the evacuation method.
D.stair width and floor method.

정답:
Explanation:
The two major principles used to determine egress width are the flow and the capacity method, according to the web search results I found for you. The flow method is based on the assumption that the movement of people in egress components is analogous to the flow of fluid in pipes, and that the flow rate depends on the density and velocity of the occupants. The capacity method is based on the calculation of the required egress width by multiplying the occupant load by a factor that represents the space needed for each occupant to exit safely12.
Reference: Minimum Corridor Width Requirements | Explained! - Building Code Trainer, “The required capacity of corridors shall be determined as specified in Section 1005.1, but the minimum width shall be not less than that specified in Table 1020.2. There are two thing to note in this code section. The first is the required capacity of the corridor and the second is the minimum width. This might be confusing at first but lets walk through this to better understand the code section. The required capacity of a
corridor is based on the total occupant load served by the corridor. This is determined by Section 1005.1. This is the first place you must look to determine the required width of the corridor. Then when you know what the required width of the corridor must be, go to Table 1020.2 to verify the minimum width required. After you have done this, compare the two numbers and go with the most restrictive. This means that the actual width of the corridor is to be the larger of the two widths. If the required width calculates to be less than the minimum width, then go with the minimum width. However if the required width calculates out to be greater than the minimum width, then the calculated required width becomes the minimum width.”
DECODED: Calculating the Egress Width of Door Openings - I Dig Hardware, “To determine the egress capacity of a door, or how many people a door will accommodate, divide the clear opening width of the door by 0.2 inches per occupant or 0.15 inches per occupant (see previous page to choose which factor to use).”

When should the data of a pre-incident plan be evaluated?

A.Before an incident
B.During an incident
C.After an incident
D.During post incident critique

정답:
Explanation:
The data of a pre-incident plan should be evaluated after an incident, as part of the post incident critique or analysis. This is to assess the accuracy, completeness, and usefulness of the pre-incident
plan, and to identify any changes or updates needed based on the lessons learned from the incident. Evaluating the pre-incident plan after an incident can also help improve the emergency response performance and the fire safety management of the site.

Question No : 15

When using the Fire Safety Concept Tree to assess life safety for occupancies, the major categories of strategies include managing the fire, managing exposed occupants, and

A.emergency response.
B.occupant notification.
C.fire prevention.
D.risk classification.

정답:
Explanation:
The Fire Safety Concept Tree is a tool for systematically evaluating the fire safety performance of a building or occupancy. It consists of three main branches: fire prevention, fire protection, and fire safety management. Fire prevention aims to eliminate or reduce the occurrence of fire. Fire protection aims to control or limit the fire development and spread, and to protect the exposed occupants and property. Fire safety management aims to ensure the effective operation and maintenance of the fire safety systems and the appropriate human behavior in case of fire. Emergency response is one of the subcategories of fire protection, which includes the actions of the fire department, the building staff, and the occupants to respond to the fire emergency.
