Knowledge Check

1. Business occupancies are normally divided into group areas and individual working spaces that have the indirect positive effect of:

separating the occupancy into multiple use or incidental use spaces.

compartmentalizing space and separating it into fire and smoke zones.

creating high fire loads and restricting exit access for customers and clients.

forcing oxygen from the spaces and causing a fire to become ventilation limited.

2. Model codes are enforceable when:

the AHJ adopts them.

the codes are in revision.

they are in their original form.

they are based on NFPA standards.

3. When planning mitigation for a compartment fire, it is crucial to consider the location of the fuel package because the:

location of the fuel package may impede the effects of pyrolysis.

compartment may not self-ignite based on the products of the fuel package.

fuel package location determines the speed of fire development within the compartment.

location of the compartment within the overall structure matters more than the fuel package's location.

4. Which type of factory-built home may have an increased risk of a basement fire with the potential to vertically extend through other concealed spaces within the structure?

Precut

Modular

Panelized

Hybrid precut

5. What type of occupancy is separated into several subdivisions based on the relative hazard or risk to life created by activity performed within the structure?

Health/care

Military/tribal

Factory/industrial

Educational/institutional

6. Smoke control systems that utilize the opposed air flow method are appropriate in buildings with open floor plans because they use high velocity air aimed at the fire's origin to:

dilute the contaminants.

collect smoke at its highest point in a large space.

keep smoke from migrating into unaffected areas.

maximize the movement of smoke from one building to another.

7. Occupancies equipped with sprinklers and/or standpipes are provided with water through a:

waste an

public or private water supply.

community water tank or water well.

sunken water tank in the building's lowest level.

8. What construction requirement has led to a reduction in fire loss and residential fatalities in manufactured homes?

Installation of steel trusses in roof construction

Use of flame-retardant materials in interior finishes

Addition of wooden I-beams with numerous holes cut in them for utility lines

Use of adhesives and other industrial glues to connect engineered structural members

9. Which type of fire protection system is installed in occupancies where it is impractical or impossible to maintain water storage for fire protection?

Stationary fire pumps

Class I standpipe system

Public fire alarm system

Smoke management system

10. The fire resistance of a manufactured home will vary depending on the:

home's size.

home's shape.

age of the home.

location of the home.

11. What improvement has been made to the fire protection elements of building construction to meet the requirements of modern, more stringent fire and safety codes?

Increased use of stationary fire pumps in public buildings

Decreased use of thermal insulation in Type V construction

Hazardous process eliminated from certain construction types

Lightweight construction elements eliminated from factory-built homes

12. Under fire conditions, the plywood I-beams used in Type V construction:

are extremely stable and resistant to collapse.

fail and bum much more rapidly than solid lumber.

produce ventilation-limited conditions and backdraft.

prevent fire travel due to the lack of voids or concealed spaces.

13. Canadian classification codes restrict the combination of multiple, accessory, or incidental use occupancies when a(an):

high fire-resistive wall is installed.

high-hazard occupancy is involved.

educational occupancy is used for assembly.

occupancy has vinyl siding in its construction.

14. Which type of public alarm system automatically retransmits an alarm to all fire stations within the jurisdiction?

TypeA

TypeB

Type C

TypeD

15. What hazards do classified educational occupancies pose?

High fire loads and limited evacuation ability

High occupant loads and wide variety of uses

High manufacturing risk and low occupant loads

High value contents and prefabricated furnishings

16. The National Fire Protection Association develops and publishes the majority of the __ concerning fire protection, electrical systems, and life-safety systems used in the U.S. and Canada.

construction criteria

consensus standards

adopted model codes

occupancy classifications

17. What construction feature of manufactured home provides an additional source of oxygen during a fire?

Vinyl siding

Large basements

Open crawl spaces

Concrete slab anchors

18. Modem Type IV facilities with curved or vaulted ceilings are constructed with glue-laminated beams that may fail when exposed to fire because the:

unburned fire fuel may melt the laminate coating.

heat may affect the glue holding the laminates together.

higher exterior pressure may cause the laminate beams to fail.

oxygen-rich fuel gases may warp the studs the beams are attached to.

19. Type I construction provides the highest level of protection from fire spread because:

columns, beams, and joint are composed of small-dimensioned lumber.

exterior walls and structural members are partiality constructed of wood.

all structural members are composed of materials with a high fire-resistance rating.

all structural members are composed of steel materials that will not contribute to combustion.

20. Which building element found in Type V construction is likely to produce dense, dark, oily toxic smoke when it bums?A

Vinyl siding

Industrial glue

Exterior wall cavities

Prefabricated wood truss system

21. Class III standpipe systems are designed to allow:

only firefighters and fire brigade members to attack fires.

modifications based on local need.

installation on water tanks or towers.

occupants and firefighters to apply water on a fire.

22. The set of requirements that make up a model code are:

building codes.

prescriptive codes.

consensus policies.

federal regulations.

23. The classification of a residential board and care occupancy, as a whole, is based on the:

Process that poses the highest hazard.

resident posing the most significant risk.

type structure in which the facility operates.

evacuation methods present in the structure.

24. Type I construction provides structural stability during a fire, but this structural integrity can be weakened by the heat generated by combustible:

masonry walls.

concrete slabs.

interior furnishings.

steel framing components.

25. What significant classification challenge is posed by buildings used for intermingled purposes?

Only the initial occupancy classification of the building can be used.

Only the least restrictive fire and life safety requirements can be enforced.

It is impractical to apply all the applicable fire codes to a single occupancy.

It is impractical to separate portions of the building for different classifications.

26. What determines the model code classifications of storage facilities?

Which subdivision the facility falls into based on its usage

Evacuation capabilities that could be classified as slow, prompt, or impractical

Whether staff members are responsible for the safety and welfare of customers

Combustibility or flammability of its contents and how these contents are stored

27. Which type of construction may contain a high concentration of wood that can contribute to a fire's intensity once it starts?

Type I

Type IV

Type V

TypeX

28. A consideration when responding to a fire in a Type II building is that they are more prone to collapse because:

metal roof decks are more likely to fail than roof decks made of laminated wood.

the steel components have a lower fire-resistance rating than a Type I building.

they are constructed oflighter-weight materials with lower-fire resistance ratings.

the void spaces inside the roof and truss system are less protected than in Type I construction.

29. Structures classified for incidental use must conform their fire protection systems to the:

code specifics for residential occupancies.

code specifics for institutional occupancies.

requirements for the primary use of the structure.

requirements for the secondary use of the structure.

30. Which consensus-based standard writing organization also develops testing processes used in the development of safety products?

ASTM International

Underwriters Laboratories

Standards Council of Canada

American National Standards Institute
