OBJ 2.2

Question 1

Basement

Answer 1

Defined by what it is not; it is a story that is not above grade plane, as defined in IBC Section 202.

Question 2

Atrium definition and biggest concerns for HSW

Answer 2

By definition, it is an opening connecting two or more floor levels that is closed at the top. The biggest concern for atriums involves the control of smoke. Atriums are required to have smoke management systems.

Question 3

Flame spread and smoke generation

Answer 3

Requirements for how long it takes a fire to move along the surface of a building material and how much smoke is generated under fire exposure.

Question 4

Area or occupancy separation rating

Answer 4

Requirements for how long it will take for fire to penetrate a wall partition, floor, or roof assembly.

Question 5

Construction type

Answer 5

Categorized by materials based on their resistance to fire in structural applications.

Question 6

Accessible route

Answer 6

A continuous unobstructed path connecting all accessible elements in a building and outdoor areas. Clear width = 36 inches clear except at doorways, which are minimum 32 inches clear. The running slope shall not exceed 1:20 (then it becomes a ramp).

Question 7

Horizontal exit

Answer 7

A means of egress whereby occupants can exit one area of the building by going to an adjacent portion of the building that is protected by a fire wall.

Question 8

Clear floor space for a single stationary wheelchair

Answer 8

30″ x 48″.

Question 9

Detectable warning

Answer 9

Surface feature consisting of raised domes built into a walking surface or other element to warn of a hazard on a circulation path.

Question 10

Floor area required for a single wheelchair to maneuver a 180-degree turn

Answer 10

A 60-inch diameter circle or a 5′0″ x 5′0″ T-shaped space.

Question 11

Minimum width for passage of two wheelchairs

Answer 11

Sixty inches.

Question 12

Maximum ramp slope per ADA

Answer 12

1:12 or 8.33%.

Question 13

True or False? Clear floor area, turning space, and accessible route may overlap in bathrooms to meet ADA requirements.

Answer 13

True.

Question 14

True or False? ADA is a national building code that is enforced in building inspections.

Answer 14

False. ADA is civil rights legislation passed in 1992 that property owners must conform to for protection against civil suits.

Question 15

Flashover

Answer 15

A flashover is the sudden ignition and rapid spread of a fire engulfing a space. Flashover is caused by increased temperatures due to thermal radiation feedback, which is the energy that a room on fire radiates back to the combustible material in the room. This radiation raises the temperature to the point of ignition. Size, shape, contents, air supply, and insulation are all factors in how a space will flashover. A flashover means a fire is fully developed.

Question 16

Backdraft

Answer 16

A backdraft is an event that occurs when a source of oxygen is introduced to a smoldering fire, igniting hot gases in the room and causing an explosion. It is an air-driven event in contrast to flashover, which is a temperature-driven event. Backdrafts occur in the decay stage of a fire.

Question 17

How far does a handrail have to extend past the top and bottom of the ramp slope?

Answer 17

A 12-inch extension of the handrail is required.

Question 18

The maximum distance between stair landings is ___ vertical feet.

Answer 18

Twelve.

Question 19

Stairways wider than ___ feet need an intermediate handrail.

Answer 19

Five.

Question 20

A door in a one-hour corridor must have a ___ minute rating.

Answer 20

Twenty.

Question 21

A dead-end corridor is limited to 20 feet in an unsprinklered building and ___ feet in a sprinklered building.

Answer 21

Fifty.

Question 22

___ is required for any objects mounted to the wall 27″ to 80″ above the finished floor that protrude more than 4″ into the path of travel.

Answer 22

Cane detection.

Question 23

Restrained vs. unrestrained

Answer 23

In regard to fire-rated floor assemblies, restrained and unrestrained refer to whether a floor is connected to a supporting structure in a way that allows for it to expand longitudinally when subjected to fire. In other words, in a restrained assembly, the structure around the floor beams can withstand thrust from thermal expansion of the floor beams.

Question 24

Type I Construction

Answer 24

Type I is the most fire-resistant type of construction. Examples: protected steel and reinforced concrete structures and high-rises.

Question 25

Type II Construction

Answer 25

Type II is noncombustible construction. Similar to Type I but less fire-resistant. Examples: unprotected steel buildings and school buildings.

Question 26

Type III Construction

Answer 26

Type III is ordinary construction. Exterior walls and structure are noncombustible or of limited combustion. Example: strip mall.

Question 27

Type IV Construction

Answer 27

Type IV is heavy timber construction, also commonly called mill construction.

Question 28

Type V Construction

Answer 28

Type V is wood frame and is the most combustible. A typical home is an example.

Question 29

Subtypes A and B

Answer 29

Four of the five types of construction have subgroups of A or B. Subtype A means there is an additional layer of protection on the structural members that increases the fire resistance by one hour. Subtype B means unprotected. Type IV (heavy timber) does not have subtypes.

Question 30

Autoexposure

Answer 30

In fire protection engineering, autoexposure is the spread of flames from one floor to the floor above along the outside of the building, through the windows.

Question 31

Health codes

Answer 31

They regulate aspects of building design that have to do with sanitation. Examples include health care, food service, and swimming pools.

Question 32

Truncated domes

Answer 32

A common type of tactile paving used as a detectable warning in pathways to alert blind people to street intersections and transit platform edges.
