– Non-gas-fired
• NFPA 1403, Standard on Live Fire Training
Evolutions, covers the specific requirements for
both types of structures.
7
Code Requirements
• NFPA 1402, Guide to Building Fire Service
Training Centers, is the guideline to use when
building a new facility.
• A standard is not law unless adopted by the
authority having jurisdiction (AHJ) or
governmental authority.
7
Making and Enforcing the Rules
• Facility manager
– Ensures that concise
procedures are in place
• Procedures include
normal to emergency
activities.
• Some facilities post the
rules.

Types of Live Fire Training Structures
(1 of 11)
• Permanent live fire training structures: designed
to withstand repeated fires without incurring
damage
– Gas-fired live fire training structures: permanent
structures where burn sets are fueled by liquefied
petroleum gas (LPG) or propane
– Non-gas-fired live fire training structures:
permanent structures where fires are fueled by
Class A materials
7
Types of Live Fire Training Structures
(2 of 11)
• Structures made of steel,
concrete, masonry construction
• Can be freestanding, part of a
training tower, or mobile
structure
• Built with extremely heatresistive material, allowing for
repetitive fires and extended use
7
Types of Live Fire Training Structures
(3 of 11)
• Thermal shock: ceiling, walls,
floor surfaces heat unevenly
and expand; then rapidly,
unevenly are cooled by hose
streams.
• Newer facilities have insulation
panels and replaceable, nonload-bearing walls.

Operations (1 of 3)
• Operations in permanent live fire training
structures require less personnel; less laborintensive than acquired structures.
– Still need to follow considerations and perform a
walk-through
• Instructors must be qualified by the AHJ.
• Ignition decisions made by instructor-in-charge
and safety officer.
– Follow Go/No Go sequence.
7
Operations (2 of 3)
• Gas-fired systems have
automatic ignition
systems.
– Instructor must visually
confirm burn area is clear
of personnel.
– Communication is critical.
7
Operations (3 of 3)
• Non-gas-fired systems
– Setup of burn rooms and ignition process follow
same procedures as acquired structures.
– Nobody can operate inside the structure alone.
7
Overhaul
• Once evolutions complete:
– Check for injuries.
– Check for damage to PPE and SCBA.
– Report any damage, deficiencies, and repairs
needed.
– Leave facility in a safe condition.
7
Summary (1 of 2)
• Use of permanent live fire training structures
reduces chance of problems that occur in

• They are designed to withstand repeated fires
without incurring damage.
• Gas-fired structures are fueled with liquefied

temperatures than gas-fired structures.
7
Summary (2 of 2)
• Develop preburn plan.
• Fire structure must be properly maintained and
structural integrity inspected once a year.
• Fire structure is inspected for hazards and
prepared before training evolutions.
