LIGHTWEIGHT CONSTRUCTION

• CONVENTIONAL CONSTRUCTION

  structural members that depend on size for
  strength. The greater the span for a structural
  member the larger it has to be to support a given
  load.

LIGHTWEIGHT CONSTRUCTION

• DEFINITION
• Lightweight construction does not derive its
  strength from size. Is obtained from multiple
  members that are in compression and tension.
• Additionally, the strength of the individual
  structural member is dependent on the sum total
  of the other members thus, if one member fails,
  other members may fail.

• SIZE-UP
• Preplanning - Your district
• Onscene -
• Walk around structure sizing up old/new
• construction methods and,
• determine strengths and hazards by
• undressing the building in your mind

LIGHTWEIGHT CONSTRUCTION

• KEY POINTS
• Preplan your district, pay special attention to
  lightweight construction
• Size-up the scene, develop a plan, implement the
  plan, re-evaluate
• Communicate onscene types of construction and
  changes as they occur
• Risk vs. Benefit
• Great personal risk to save a life
• Least personal risk to save property

52
LIGHTWEIGHT CONSTRUCTION

• KEY POINTS CONTD
• Lightweight construction exposed to fire shortens
  the time to collapse
• Hotter fires and quicker response times lead to
  firefighters being at the scene during times of
  flashover and collapse
• Accountability with no freelancing is crucial.
  Know the plan, STAY TOGETHER
• LIVE TO FIGHT ANOTHER DAY
