2. Three basic types of rated assemblies:
Fire barriers
Fire partitions
Horizontal assemblies
3. Fire barriers are walls that a fire resistant rating
and in most cases must be continuous and extend
vertically from the bottom to the top of the
floor/ceiling assembly
Additional fire blocking is required at the intersection
with other rated elements
Openings are limited
Opening assemblies need to be rated
4. Floor/ceiling assemblies are horizontal assemblies
Limited openings
Openings and penetrations must be rated as well
5.
6. Fire partitions are similar to fire barriers but less
restrictive
Separate exit access corridors, tenant spaces in malls,
dwellings and /or sleeping units
Allowed to stop at the rated ceiling system
Not required to be a full enclosure
Rating of at least one hour
7. Ratings depends on purpose, occupancy
classification and if space has sprinklers
Openings required to be protected but not limited
8.
9. Fire enclosures separates occupancy types
Not required between similar hazardous
occupancies
10. Multiple tenants of different occupancies in the
same building
Single user with multiple occupancies or uses within
the same structure
11.
12.
13.
14. Tenant separations in malls required to be rated
Dwelling and sleeping units in residential
occupancies to be separated by fire partitions
Some incidental accessory occupancies to be
separated
15. Required for vertical shaft enclosures as elevators,
dumbwaiters, mechanical chases, etc.
Smoke barriers provide protection form movement
and passage of smoke and fire gases
Barriers are usually rated
Partitions are not required to have fire resistance
rating
16. Complete opening assemblies in rated barriers are
required to be also rated
Although ratings of opening assemblies – doors,
windows, and other penetrations – is lower than the
assembly – the quantity and dimensions are limited
Opening assemblies include the door, the frame, and
other required hardware.
All rated doors are required to have a self closing
device that will close the door after each use. Not
necessary for it to be automatic (usually electrically
activated)
17.
18. Glazing products in rated assemblies must:
Stay in place during a fire
Resist thermal shock – by a hose stream
Strength from human contact
Resist heat transfer to unexposed side
19. Codes allow the use of glass in some rated
partitions – type, size, and quantity is limited
Wired glass – wire mesh sandwiched between two
layers of glass
Safety resists impact
Nonsafety does not resist impact
Only type of glass addressed by codes for use in
rated opening protectives
20. Specialty tempered glass – treated for fire
resistance
Some can be used in 1 hr rated walls
Cannot be used near sprinklers since it does not pass
the hose stream test
Glass block
Can be used in some 1 hr rated partitions – glass rated
to 45 minutes
21. Clear ceramics
High resistance
to heat
Resists thermal
shock
20mins to 2hr.
Up to 23s.f. can
be used
Sometimes has
more distortion
and tint
23. Firestops and smokestops
F-rated and T-rated
T is stricter than F as it
includes a maximum
temperature resistance
24. Fireblocks and Draftstops
Restrict the spread of smoke and
fire through concealed spaces
Fireblocks – small spaces
Draftstops – large spaces
Damper systems
Interrupts air flow through ducts
going through rated assemblies

device.
A. True
B. False

28. A fire-protected door can also be used as a
smokestop door.
A. True
B. False
Fire barriers are typically used to create
compartments within a building.
A. True
B. False
29. Occupancy separation walls and demising walls are
the same thing.
A. True
B. False
Doors with fire-protection ratings are not allowed to
have glass lites as part of the door.
A. True
B. False
30. __________Walls are used to create a continuous
vertical separation within a building or between two
different buildings.

and _____________.
