History
33
History Iroquois Theater Fire of 1903
December 30th,1903 602 deaths Lead to improved fire safety in theaters
34
History Triangle Shirtwaist Factory Fire of 1911
March 25th,1911 Largest industrial disaster at the time 146 deaths Lead to legislation increasing Fire Safety Standards
35
History Binghamptom Clothing Factory Fire of 1913
July 11th,1913 31deaths Lead to better fire exits
36
History Coconut Grove Night Club Fire of 1942
November 28th,1942 492 deaths Lead to reform of safety standards and codes Outward swinging exit doors Upgrades to treatment and care of burn victims
37

Common Materials
39
Common Materials Wood Masonry Cast Iron Steel Reinforced Concrete
Gypsum Glass Fiberglass
40
Common Materials Wood Most common Used in Load-bearing
Nonload-bearing walls Trusses Joists Rafters Etc.
41
Common Materials Masonry Block Brick Reinforced Masonry
Unreinforced Masonry (URM) Stone
42
Common Materials Cast Iron Rarely used in modern construction
Older buildings May crack and shatter with rapid cooling Spalling Connections can fail Leads large heavy sections falling
43
Common Materials Steel
Primary structural support in large modern buildings Elongates and warps in high heat As much as 4” in a 50’ ft. section May buckle and fail at ends or middle if restrained At or above temp. of 1,000° F
44
Common Materials Reinforced Concrete Concrete tilt-ups
Pre and Post-tensioned slabs Uses compressive strength of concrete with tensile strength of steel Has rebar or steel Can lose strength through spalling Look out for cracks and spalling in exterior walls
45
Common Materials Gypsum Inorganic product
Plaster and wallboards are made from High water content Absorbs heat Common interior lining
46
Common Materials Glass and Fiberglass Glass Used as exterior coverings
No real thermal protection May Shatter Fiberglass Used for insulation
