Trusses And Fire
Thus you have no way of knowing how long
before it fails!!!

• They fail quickly when heated, in as little as
  1-2 minutes!
• They fail without warning
• They dont get spongy before failing so
  sounding a roof is of no help

You have no idea how long the truss has been
being heated from the fire when you arrive on
the scene.

TRUSS IDENTIFICATION

• In recognition that truss assemblies can, have
  and will fail when exposed to fire conditions,
  the following has been enacted to provide a
  system to notify firefighters of important
  information about structures including the
  presence of trusses.

6

• The system is a very simple one but, like
  anything else, can only be effective if all
  firefighters are keenly aware of it and have a
  good understanding as to how to read and
  interpret it.
• Looking for this should be a standard part of
  every scene size up.
• The first one at an incident to see this sign
  should announce its presence and contents so
  that everybody is made aware of this vital
  information.

. Section 382-a of the Executive Law provides
that commercial and industrial buildings and
structures that utilize truss type construction
shall be marked by a sign or symbol that informs
persons conducting fire control and other
emergency operations of the existence of truss
construction. Section 382-a further directs the
State Fire Prevention and Building Code Council
to promulgate rules and regulations it deems
necessary to carry into effect the provisions of
the statute. This Part establishes certain
requirements pertaining to the identification of
buildings and structures that utilize truss type
construction.

greater than would be possible with any of the
individual members on their own. Truss type
construction shall not include (1) individual
wind or seismic bracing components which form
triangles when diagonally connected to the main
structural system and (2) structural components
that utilize solid plate web members.

the law)
Type 3-Ordinary Construction
Trusses in roof assembly
The 'B' is because it is a Type IIIB building
these are the classifications the Uniform Code
uses (IA, IB, IIA, IIB, IIIA, IIIB, IV, VA, VB),
found in Table 503 of the Building Code of New
York State. This is not required to be on this
label but often is included.

The Law and the FD

• The Law makes this vital info available to you.
  Now its up to you and your department to use it.
• Enter this info into every pre-plan the presence
  and/or absence of any trusses.
• It should be an SOP that the first firefighter
  who sees one of these signs at an incident
  announces this information on the radio so
  everybody becomes aware.
• Conduct walk throughs of these structures
• Conduct table top exercises so everybody knows
  how to deal with incidents in these (and all
  other) structures.

24
1264.2 Enforcement.

• (a) Subdivision 4 of section 382-a of the
  Executive Law directs local governments to
  provide for enforcement of the statute.
  Enforcement of section 382-a of the Executive Law
  shall include enforcement of the provisions of
  this Part. A fee of fifty dollars shall be paid
  by the owner of a building with truss type
  construction to the authority having jurisdiction
  for enforcement of section 382-a of the Executive
  Law prior to the issuance of a building permit.
• (b) This Part shall not apply within a city with
  a population of one million or more persons.

25
1264.3 Definition.

• For the purposes of this Part, truss type
  construction shall mean a fabricated structure of
  wood or steel, made up of a series of members
  connected at their ends to form a series of
  triangles to span a distance greater than would
  be possible with any of the individual members on
  their own. Truss type construction shall not
  include
• (1) individual wind or seismic bracing components
  which form triangles when diagonally connected to
  the main structural system and
• (2) structural components that utilize solid
  plate web members.

26
THE GOOD PART IS.

• Now, any structure built or added on to after the
  effective date (12/29/04) that has any trusses in
  it, will be required to display this signage.
• This should make every firefighter aware of the
  presence of trusses.

27
BUT

• The law is based on the weakest link.
• Example a formerly Type I building gets an
  addition that features wooden structural members.
  
• That changes to entire structure to Type V.

28
RECOMENDATION

• Use this signage like anything else remember it
  but dont take it as absolute gospel
• Make sure your pre-plans are always up to date
• Make sure all your personnel know how to read and
  use a pre-plan
• Use your pre-plans !!

29
Also remember..

• It doesnt apply to structures built before
  12/29/04 unless they have an addition put onto
  them.
