Question 1

The Safety Class for propane refrigerant R-290 is

Correct Answer: B. A3
Explanation:

The safety class for propane refrigerant R-290 is A3, which means it has no toxicity but high flammability. The safety class is determined by the ASHRAE Standard 34, which assigns a capital letter (A or B) for the toxicity level and a number (1, 2, or 3) for the flammability level of a refrigerant. Propane has a very low global warming potential and ozone depletion potential, but it also has a very low flash point and high auto ignition temperature, which make it highly flammable in the presence of ignition sources.

Question 2

The computer simu-lation egress model that is often referred to as the hydraulic model and also known as

Correct Answer: D. movement model.
Explanation:

The hydraulic model is a type of movement model that simulates the flow of people through egress components based on equations derived from fluid dynamics. It is also known as the single-parameter estimation model because it uses only one parameter, the effective width, to describe the movement of people. The hydraulic model does not account for the behavioral aspects of egress, such as pre-evacuation time, decision making, group dynamics, or communication. A behavioral simulation model is a different type of egress model that incorporates these factors.

Question 3

Environmental Protection Agency standards require solid waste be treated as hazardous if it is a listed waste and/or

meets the characteristics prescribed by the standard for toxicity, reactivity, corrosivity, and

Correct Answer: C. ignitability.
Explanation:

The correct answer is C. Environmental Protection Agency (EPA) standards require solid waste be treated as hazardous if it is a listed waste and/or meets the characteristics prescribed by the standard for toxicity, reactivity, corrosivity, and ignitability. A listed waste is a waste that appears on one of the four lists of hazardous wastes in the Code of Federal Regulations (CFR) part 261 subpart D1. A characteristic waste is a waste that exhibits one or more of the following traits: toxicity, reactivity, corrosivity, or ignitability2. Toxicity is the ability of a waste to leach harmful chemicals into the environment. Reactivity is the tendency of a waste to undergo violent chemical reactions or generate toxic gases. Corrosivity is the property of a waste to corrode metals or damage living tissues. Ignitability is the capacity of a waste to catch fire under certain conditions2. These characteristics are defined by specific tests and criteria in the CFR part 261 subpart C3. The EPA standards for hazardous waste are based on the Resource Conservation and Recovery Act (RCRA), which is the federal law that regulates the management of solid and hazardous waste in the United States4.


Question 4

Which of the following approaches can be used to manage smoke in large that consists of allowing smoke to till the large volume space while occupants evacuate the atrium?

Correct Answer: C. Steady clear height

Question 5

The removal of flammable vapors by displacement for cleaning a storage tank can be accomplished by displacement with air, inert gas and

Correct Answer: B. water
Explanation:

The removal of flammable vapors by displacement for cleaning a storage tank can be accomplished by displacement with air, inert gas, and water. Water is a common method of displacing flammable vapors from tanks, as it is readily available, inexpensive, and non-reactive with most fuels. Water can be sprayed into the tank to create a water seal that prevents the vapors from escaping and reduces the oxygen concentration in the tank. Water can also be used to rinse the tank walls and remove any residual fuel. However, water displacement may not be suitable for some tanks that contain water-sensitive or water-soluble fuels, or for tanks that have limited drainage or disposal facilities.


Question 6

Which type of plan review may provide information about a modification such as the removal of an abandoned underground flammable liquid tank?

Correct Answer: D. As built plan review
Explanation:

An as built plan review is a type of plan review that may provide information about a modification such as the removal of an abandoned underground flammable liquid tank. An as built plan review is conducted after the construction or alteration of a building or system is completed and before the final approval or acceptance by the AHJ. An as built plan review verifies that the building or system conforms to the approved plans and specifications and complies with the applicable codes and standards. An as built plan review may also identify any changes or deviations from the original plans that occurred during the construction or alteration process, such as the removal of an underground tank.

Question 7

Besides smoke detection what other permitted detection for Phase 1 elevate recall is typically used m ambient conditions?

Correct Answer: B. Heat detector

Question 8

What type of test is used by fire investigators following scientific methods and includes ignition temperature flame spread of materials flashpoint, and rale of heat release, among others?

Correct Answer: B. Flammability test

Question 9

Which type of heat detector automatically resets after operation, when the ambient temperature drops below the operating temperature?

Correct Answer: A. Rate-of-Rise
Explanation:

A rate-of-rise heat detector is a type of heat detector that automatically resets after operation, when the ambient temperature drops below the operating temperature.This is because a rate-of-rise heat detector operates on a rapid rise in element temperature of 6.7 to 8.3C (12 to 15F) increase per minute, irrespective of the starting temperature1If the temperature rise stops or reverses, the detector will reset itself and stop sending an alarm signal to the control panel2A rate-of-rise heat detector can also have a fixed temperature element that will trigger an alarm at a specified temperature, but this element is not self-resetting and requires replacement after activation2

Question 10

What fs the level of disaster that requites substantial state and federal assistance with military involvement?

Correct Answer: D. Catastrophic disaster

Question 11

What is me minimum number of cycles used for joint system movement testing of a Class ll firestopping system?

Correct Answer: C. 100 cycles

Question 12

Hydrogen cyanide falls into which class of fire gas toxicants?

Correct Answer: B. Asphyxiants or narcosis-producing toxicants C.

Question 13

Panic hardware devices are designed to facilitate the release of the latching device on a door with a pressure note xceeding

Correct Answer: C. 15 pounds (6.8 kg.) is applied in the direction of exit travel.
Explanation:

Panic hardware devices are designed to facilitate the release of the latching device on a door with a pressure not exceeding 15 pounds (6.8 kg.) is applied in the direction of exit travel. This is the maximum force allowed by the codes and standards that regulate the use and installation of panic hardware, such as NFPA 101, NFPA 80, and ANSI/BHMA A156.3. The purpose of this requirement is to ensure that the doors can be easily opened by anyone in an emergency situation, without prior knowledge or special effort.

Question 14

Which smoke detector type contains a small amount of radioactive material and functions by sensing a decrease in conductance of the air when smoke particles enter the chamber?

Correct Answer: D. lonization
Explanation:

The smoke detector type that contains a small amount of radioactive material and functions by sensing a decrease in conductance of the air when smoke particles enter the chamber is the ionization smoke detector. Ionization smoke detectors use a small amount of americium-241, a radioactive element, to ionize the air molecules inside a sensing chamber. This creates a low-level electric current between two electrodes. When smoke enters the chamber, it disrupts the ionized air and reduces the current flow. This triggers the alarm to sound. Ionization smoke detectors are more sensitive to small particles of smoke, such as those produced by flaming fires1. However, they may also be more prone to false alarms from cooking or steam, and they require proper disposal of the radioactive source2.
