FIRE FOCUS
This turn-of-the-century religious structure is typical of those in older communities. With fire this advanced on arrival, you should plan for collapse of the roof structure. The fire load here is in the roof area —the truss loft.
At heavily involved peak-roof religious structures, there exists a critical factor (that which must be assessed or overcome if you are to support an aggressive, interior attack; if it is impossible to attain, you must switch strategy to defensive and plan to lose the structure): to create a large, expanding vertical ventilation opening at the ridge pole to halt the horizontal spread of fire throughout the truss assemblies.
