1. : type of door that protect openings in fire - rated walls, block spread of fire within structure, and when properly maintained, are very effective at limiting spread of fire and total fire damage.
2. : construction type composed of materials that will not contribute to fire development or spread, do not meet stricter requirements of materials used in type i. and do not add to fuel load.
3. : roof truss type constructed of wood or metal, is generally used to support flat roofs and floor assemblies
4. : construction type with exterior load - bearing walls composed entirely of wood and may have veneer of stucco, brick, or stone may be constructed over wood framing
5. : type of homes assembled on - site from pre - constructed panels.
6. which type of building construction provides the highest level of protection from fire and structural collapse?

a. type i
b. type ii
c. type iv
d. type v

1. type iv buildings are constructed of:

a. cast - in - place concrete.
b. steel framing members.
c. large - dimensioned lumber.
d. prefabricated wood trusses.

1. which type of factory - built home is the least expensive, usually has wheels and a permanent steel undercarriage?

a. log houses
b. mobile home
c. modular home
d. geodesic domes

1. firewalls are designed to:

a. provide the highest form of fire resistance.
b. prevent fire from spreading through void spaces.
c. prevent the spread of fire between buildings or occupancy classifications.
d. provide firefighters with protection from smoke and flames during interior operations.

Explanation:

1. Fire Doors are specifically designed for fire - rated walls to block fire spread.
2. Type II construction materials do not contribute to fire development/spread and don't meet Type I's stricter material requirements.
3. Parallel Chords (roof trusses made of wood/metal) support flat roofs and floor assemblies.
4. Type V has exterior load - bearing walls of wood (may have veneer) over wood framing.
5. Panelized Homes are assembled on - site from pre - constructed panels.
6. Type I construction (not in word bank but based on knowledge) provides the highest fire and structural collapse protection.
7. Type IV buildings are constructed of large - dimensioned lumber.
8. Mobile homes are factory - built, least expensive, with wheels and permanent steel undercarriage.
9. Firewalls are designed to prevent fire spread between buildings/occupancy classifications.

5. Panelized Homes
6. a. Type I (not in word bank but correct)
7. c. large - dimensioned lumber
