31
Q

Types of glass

A

saftey (laminated) glass- Two sheets of glass bonded to a sheet of plastic “ windshields and some rear windows”

32
Q

Types of Collapse

A
  • pancake
  • V-shaped
  • Lean-to
  • Cantilever
33
Q

Pancake

A

Upper floor & roof collapsing on the top of eachother (Leaves no voids)

34
Q

V-Shape

A

Floors or roofs fail in middle

Good chance of habitable void spaces

35
Q

Lean-to

A

One outer wall fails & other stays intact

36
Q
A
37
Q

Cantilever

A

One sidewall of multistory building collapses leaving the floors attached to & supported by the remaining sidewall

Good chance of habitable voids “Least Stable & Vulnerable to secondary collapse”

38
Q

Hazards involved in structual collapse

A
  • Environmental (utilities, atmopheric contamination, hazmat, darkness, temp, noise, fire, weather
  • Physical (wroking in and around piles of heavy irregulary shaped pieces, secondary collapse, confined space)
