Firefighters should know that fire in Type V construction presents:
High potential for fire extension within the building
When establishing a collapse zone around a building, the minimum distance should be:
1-1/2 times the height of the building
What factor must be taken into consideration when fighting a structure fire?
Length of time the fire has been burning
One of the most serious building construction hazards facing firefighters today is the:
Increased use of lightweight and trussed support systems
The structural elements of Type I construction are generally required to have a fire resistive rating of __________ hours.
2-4
What type of building construction is made up of solid heavy timber or laminated wood?
Type IV
Knowing the effect of fire on common building materials is important since it provides firefighters with ____________ during firefighting operations at a particular occupancy.
An idea of what to expect
Which is an indicator of potential building collapse?
Prolonged fire operations
The most effective method of protecting firefighters from an imminent building collapse is to:
Remove personnel from the building
A(n) _____________ is designed to prevent the spread of fire within a structure or between adjacent structures.
Fire wall
Spalling of concrete could lead to early collapse in Type I buildings because:
Reinforcing steel is exposed to the heat of the fire
A wall used to divide two adjacent structures and also could be used as a fire wall is a ____________ wall.
Party
Structure members that are of noncombustible materials but may not have fire resistive protection are identified as:
Type II
A type of wood framing that has vertical channels going from floor to floor, allowing a fire to travel uninterrupted is ____________ frame construction.
Balloon
A connecting plate used in truss construction that can be made of flat steel stock, light gauge metal, or plywood is the definition of a:
Gusset plate
One thing common to all types of trusses is that if one member fails:
The entire truss is likely to fail
Fire walls:
May divide large structures into smaller portions
What type of construction has structural members (including walls, columns, beams, floors, and roofs) that are made of noncombustible or limited-combustible materials?
Type I
Fire extension can be reduced considerably by placing ______________ inside concealed spaces.
Fire stops
If firefighters inside a building believe that the collapse of a building is imminent, the first action that should be taken is to:
Evacuate personnel within the building
A partition wall:
Simply divides two areas within a structure
A modern building construction feature that can present a serious hazard to firefighters when exposed to heat and fire is the use of:
Trusses
The usual cause of collapse of a lightweight steel truss is the:
Amount of heat generated by the fire in a structure
Fire walls are:
Usually extended from the foundation up to and through the roof of a building
Which is a hazard associated with truss construction?
A failure at one point in a truss can produce a failure in the entire truss
What is an indicator of possible structural collapse?
Accumulations of water within the structure
An all metal building is classified as a:
Type II
Conventional glass:
Is not an effective barrier to fire extension
As lead of an interview fire crew, you notice a sudden change in fire conditions after ensuring the safety of your crew. The next thing you should do is:
Notify the Incident Commander of changes you observed
The primary fire hazard in fire resistive construction is the:
Contents of the structure
