Question 1

What ate the three (3) occupant evacuation strategies in a managed sequence used when evaluating the expected occupant action?

ASheller in place, relocation/partial evacuation, and total evacuation

BArea of refuge, exit safeguards, life safety strategy

CTotal evacuation, fire safety assessment, egress analysis

DElevator evacuation, pre-determined evacuation, and unmanaged evacuation.

Answer : A

Question 2

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

Asingle-parameter estimation model.

Bbehavioral simulation model.

Cegress model.

Dmovement model.

Answer : D

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

What are the human health effects of exposure for two minutes at a concentration of less than 50 ppm of hydrogen fluoride?

ASlight eye and nasal irritation.

BMild eye and upper respiratory tract irritation.

CModerate eye and upper respiratory tract irritation.

DModerate irritation of all body surfaces.

Answer : B

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.

Question 5

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

Aspecific density.

Brelative humidity.

Cspecific gravity.

Drelative density.

Answer : C

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 specific 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 determine whether 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.

Question 6

Computers and other information technology equipment are particularly susceptible to

Aspecial extinguishing agents.

Bheat, steam, and combustion products.

Clight, hoselines, and airborn dust.

Dfoam, metal powders, and dry chemicals.

Answer : B

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 hazards 1234.
