Preincident Planning
• Process of gathering/evaluating information, developing procedures, and ensuring the information remains current; consists of:– Developing positive public relations– Conducting preincident survey– Managing preincident data– Developing preincident plans

17–7
NFPA 220 Types of Building Construction
• Type I– Fire-resistive construction– Structural members of noncombustible or
limited combustible materials

17–9
NFPA 220 Types of Building Construction
• Type II– Noncombustible or noncombustible/limited
combustible construction– Similar to Type I except that the degree of
fire resistiance is lower– May include materials with no fire-
resistance rating
(Continued)

NFPA 220 Types of Building Construction
• Type III– Exterior walls and structural members that
are portions of exterior walls are made of noncombustible or limited combustible materials
– Interior structural members may be made of wood

International Building Code® (IBC®) Types of Building Construction
• Type IA– Frame and walls – 3 hours– Floor – 2 hours– Roofs – 1½ hours
• Type IB– Frame and walls – 2 hours– Floor – 2 hours– Roofs – 1 hour (Continued)
Fire and Emergency Services Company Officer
17–17
International Building Code® (IBC®) Types of Building Construction
• Type II– Noncombustible materials but with a
reduced fire-resistance rating when compared with Type I construction
– Bearing walls and floors have a 1-hour fire-resistance rating
(Continued)
Fire and Emergency Services Company Officer
17–18
International Building Code® (IBC®) Types of Building Construction
• Type IIA– Noncombustible fire-resistive materials
similar to Type I buildings insofar as the structural elements must be of steel, concrete, or masonry
• Type IIB– Approved combustible materials, but
materials used may have no assigned fire-resistance rating (Continued)
Fire and Emergency Services Company Officer
17–19
International Building Code® (IBC®) Types of Building Construction
• Type III– Structural elements of any materials permitted by
code– Exterior bearing walls – 2-hour rating– Type IIIA
– Materials that will provide a 1-hour fire-resistance rating throughout
– Type IIIB– Lacks 1-hour fire-resistance requirement
(Continued)

International Building Code® (IBC®) Types of Building Construction
• Type IV
– Structural elements of any type permitted by the code with exterior walls of noncombustible materials while interior building elements constructed of solid or laminated wood with no concealed spaces
– Permanent partitions
– Structural frame members – 1-hour fire-resistance rating
(Continued)
