A

Revolving door

44
Q

Often used to divide large assembly spaces such as conference rooms into smaller spaces…

A

Folding doors

45
Q

Cannot be used to protect an opening that is part of the means of egress from a building…

A

Sliding door

46
Q

Consists of a flat face panels the full height and width of the door that are attached to a solid core or hollow door…

A

Flush door

47
Q

Locally adopted building codes regulate the type of construction based on intended use, structure size and the presence or lack of automatic fire suppression systems…

A

True

48
Q

Firefighters responding to a fire in Type I constructed structure can expect the structure to remain stable longer than other types of construction.

A

True

49
Q

A veneer of stucco, brick, or stone constructed over wood framing in a Type V construction provides little additional fire protection or structural support.

A

True

50
Q

Walls can be easily breached during forcible entry due to the use of light weight construction materials in manufactured homes.

A

True

51
Q

What may be used to separate occupancy classifications within the same structure to prevent the spread of fire from one to another?

A

Fire walls

52
Q

Fire in basements may be more hazardous that in other compartments because of the limited means of ingress/egress.

A

True

53
Q

Which type of stairs are not required to be part of the means of egress system and typically connect no more than two levels?

A

Access or convenience stairs

54
Q

What should firefighters do to maintain the integrity of a protected stairwell?

A

Maintain door control

55
Q

What type of roof creates a void that can conceal fire and allow it to burn undetected?

A

Rain roof

56
Q

What type of door has wings that collapse under pressure to provide an unobstructed opening during an emergency?

A

Revolving doors

57
Q

What type of door will act as a significant barrier to the fire if it is closed at the time even if it has not been specifically designed as a fire door?

A

Solid core door

58
Q

What type of fire door is commonly used in stairwell enclosures or corridors that require a fire door?

A

Swinging doors

59
Q

Which types of window or window feature can create a hazard during a fire because they do not allow for rapid egress?

A

Security windows or security bars

60
Q

Why is it incorrect to refer to Type I construction as fire proof?

A

While the structure will not burn, the structure may degrade from the effects of fire.

61
Q

What conditions may Type IV buildings contain that can affect their behaviour during a fire?

A

The high concentration of wood can contribute to the intensity of a fire once it starts and the collapse of masonry walls can be caused by loss of structural integrity of timber.

62
Q

What dangers can basements pose during fire fighting operations?

A

Fires in basements can damage floor joists and load bearing walls that support the upper floor and structure. Stairs can provide a flow path for the movement of air, fire gases, smoke throughout the structure. Also low visibility conditions.

63
Q

Why should firefighters not enter the void area in a rain roof to cut a hole in the original roof for vent?

A

They can become trapped, overcome by heat and smoke in the void, fall through a weakened roof, be caught in an extreme fire condition as heated gas and fresh air mix.

64
Q

Vertical Doors…
A door that opens in a vertical plane is known as an overhead door and is often found in industrial occupancies for applications such as… p103

A

Loading dock doors
Garage doors
Freight elevator doors
Fire doors protecting openings that are not part of the required means of egress

65
Q

What is spalled concrete normally an indicator of?

A

Spalled concrete usually indicates the expansion of moisture in masonry materials due to the exposure of heat of a fire. The expansion of the causes the material’s surface to disintegrate, resulting in explosive pitting or chipping of the material.

66
Q

This type of door ordinarily closes under the force of gravity when a fusible link melts, but motor driven doors are available…

A

Overheard rolling steel fire doors

67
Q

A fusible link on a swinging fire door depends on the heat from a fire to close, so…

A

A significant amount of smoke may flow through the door before the door is released.

68
Q

Is hung from an overhead track with rollers or guides similar to those used by a sliding door. Can be used in residential and commercial occupancies to divide large rooms into small rooms. These horizontal doors must meet specific requirements to be tested and listed as a means of egress.

A

Horizontal fire doors

69
Q

Which type of material is often used in the core of a heavy corrugated steel door?

A

Styrofoam

70
Q

How are vertical doors (overhead garage style doors) commonly used?

A

Fire doors protecting openings that are not part of the required means of egress
Loading dock doors
Garage doors
Freight elevator doors

71
Q

Wood trusses are assembled using metal gusset plates that only penetrate about 3/8” into wood.

A

As wood burns away from the plates during a fire, the plates fall out and are no longer a structural support for the truss.

72
Q

Which type of door has flat face panels that are the full height and width of the door, and are attached to a solid or hollow core door?

A

A flush door
