Places Of Worship Flashcards
A
A
Older style susceptible to early collapse due to
Large high timber truss, bell tower, steeple and walls
Newer style susceptible to early collapse due to
Lightweight truss, bell tower, steeple
Minarets, bell towers, and steeples
Are exceptionally prone to collapse
The height of the bell tower
Increases the collapse potential and it may have a steeple or dome above the bell tower
The steeple above a bell tower is
More unstable than a dome above
Exposure 2 + 4 sidewalls are
Collapse dangers as they are bearing walls supporting the roof
If the roof fails
It can push the sidewalls out
If the sidewalls fail
The roof will fail
Most dangerous areas around Place of Worship are
Exposure 1 - due to steeple or bell tower
Exposures 2 and 4 - because they are bearing walls
Heavy religious statues, terrazzo, or stone flooring on the first floor
Increases collapse potential when there is fire Jin the cellar ceiling area
Attic Vents: Cellar, 1st floor, and choir loft fires
An excellent location for water application to extinguish fire in the attic or cockloft
Typically located on the front or rear of the long side of the building
If located in the front, it will be a few feet above the Rose Window
The Rose Window
Is a circular window and a TL should be placed to cover, while still outside the collapse zone in a corner safe area
High vaulted ceilings
Because these ceilings can be 60 feet or more in height - heat and smoke at the ground level will not provide an accurate indication of fire conditions above
Thermal Imaging Camera are a must to evaluate heat and fire above
2 1/2” hoseline is required to adequately reach the ceiling and apply water
Priority of TL stream application at a place of worship
If fire is located in the large open area - the First priority is a TL stream into the Rose Window
After fire is controlled in the large open space, the next priority is TL stream in the Attic Vent
If there is no fire visible in the large open area, but fire is suspected in the concealed attic of cockloft, the priority is to place water into the Attic Vent
