furnished by a firestop
manufacturer’s qualified
technical personnel or in concert
with the manufacturer by a
knowledgeable registered
professional engineer for
nonstandard conditions in which
a firestop system does not exist.
TDMM.* Page G-70
Fire Detection
The means of detecting the
occurrence of heat, smoke, or
other particles or products of
combustion.
TDMM.* Page G-79

The active means of detecting
and suppressing fires.
TDMM: Page G-79
Fire-Rated Assembly
A fire-rated architectural barrier
assembly designed and installed to
contain a fire within a specified
space for the rated amount of time.
The barrier includes both the
membrane material e.g., gypsum,
metal, concrete) and the barrier’s
interior (e.g., studs, insulation). The
barrier assembly includes the
barrier itself and any architectural
openings (e.g., windows or doors
and their frames).
TDMM.* Page G-80
Fire Resistance
A property of a material or rated
assembly of materials that can
withstand combustion and delay
the passage of flame for some
known period of time.
TDMM.* Page G-79
Firestop
A fire-rated material, device, or
assembly of parts installed in a
penetration in a fire-rated barrier
in accordance with a firestop
system or engineering judgment
to prevent the spread of fire,
temperature, and gases of
combustion.
TDMM: Page G-80
Flame
A body or stream of gaseous
material involved in the
combustion process of a fire,
which emits radiant energy
within wavelength bands
specific to the combustion
chemistry of the fuel. In most
cases, some portion of the
emitted radiant energy is visible
to the human eye.
TDMM.* Page G-81
Interstitial Space
A small or narrow space located
above or below the occupied
space on each floor. It is used
for routing building services
(e.g., lighting, heating,
ventilation, and air-conditioning
[HVAC], power,
telecommunications, plumbing).
TDMM.* Page G-101
Intumescent
The ability to expand to close
gaps or voids in through-
penetration openings when
exposed to high temperature
conditions.
TDMM.* Page G-IOI
Listed
One of four product test ratings
used in the United States (Listed,
Classified Recognized, Verified). A
product is listed after it
successfully completes a series of
mechanical, electrical, and thermal
characteristics tests that simulate
all reasonable foreseeable
hazards. This classification is
exclusive to the product for the
specific applications for which it
was tested and is not valid for
other applications.
TDMM.* Page G-111
Membrane Penetration
An opening through only one
surface or side of a barrier.
TDMM.* Page G-119
NRTL
Nationally Recognized
Testing Laboratory
An organization recognized by
the government and industry
that tests products according to
their application or purpose.
Test results are often used for
insurance underwriting.
TDMM.* G-127
Penetration
An opening made in a barrier
(architectural structure or
assembly). There are two types
of penetration: a membrane
penetration pierces or interrupts
the outside surface of only one
side of a barrier; a through
penetration pierces or interrupts
both outside surfaces
of a barrier.
TDMM.* Page G-139
Qualified
Indicates compliance or
accordance with specific
standards or requirements.
TDMM.* Page G-155
What do the terms
qualified and listed mean
when they are used to
describe a firestop system?
That the firestop system has
been tested by a nationally
recognized testing laboratory
(NRTL) and certified as
compliant with the conditions of
individual test standards.
TDMM.* Page 7-1
Name 4 secondary
functions that may be
performed by a firestop
system.
1 .Acting as environmental
protection seals
2.Providing sound attenuation or
acoustical sealing
3.Sealing around pipes that reach
high temperatures and may move
axially or laterally
4.Resisting the effects of explosion
TDMM.* Page 7-2
Name the 4 keys to
fire protection.
1 .Prevention
2.Detection
3.Suppression
4.Compartmentation (containment)
TDMM.* Page 7-3
What is compartmentation?
The process of limiting fire and
smoke using fire-resistive
barriers to contain and localize
fire, smoke, and other
combustible byproducts so that
fire can be suppressed, while
allowing occupants time to
egress and firefighters
a safe ingress
TDMM.* Page 7-3
What are the 3 pillars of
a balanced approach to
fire protection?
1 .Compartmentation
2.Detection
3.Suppression

What is a penetration?
Location where a cable, conduit,
or sleeve system passes
through an opening in a fire-
rated wall or floor.
TDMM.* Page 7-4
What type of penetration
occurs when the service
element passes through
both sides of the
assembly?
Through penetration
TDMM: Page 7-4
What type of penetration
occurs when the service
element passes through
only a single side or
membrane of the
assembly?

TDMM.* Page 7-4
Who is generally required
to properly seal the opening
to restore the integrity of
the barrier that has been
penetrated?
Generally, the trade that
penetrated the barrier is
responsible for properly sealing
it to restore the integrity
of the barrier.
