Question

Void spaces In type III ordinary construction, voids are numerous. some coins may pass through masonry walls, causing fire spread from one store to the next in a row of buildings. The obvious collapse danger with void spaces is that fire ma be ______________ with the simultaneous destruction of structural elements.

a) Contained
b) Extinguished
c) undetected
d) Propagated

Answer 1

c) undetected. The danger with void spaces in Type III ordinary construction is that a fire may be undetected, leading to a rapid and uncontrolled spread through the building and an increased risk of structural collapse.

Step-by-step explanation:

In the context of Type III ordinary construction, the void spaces present a significant risk factor for fire spread. When a fire occurs, these voids can allow flames and hot gases to move rapidly through spaces that may not be immediately visible, such as behind walls and above ceilings. The phrase 'Void spaces in type III ordinary construction' alludes to the inherent fire hazard where contained spaces within the building structure can create channels for fire to propagate undetected. Referring to the provided reference, it becomes clear that the fire can be particularly insidious and can lead to catastrophic results.

Based on the reference provided, where workers encountered extreme conditions during a fire, it suggests that the danger with void spaces is that fire may be undetected with the simultaneous destruction of structural elements. This tells us that, despite efforts such as locked stairwell doors to contain situations like theft, these security measures can backfire in an emergency, actually exacerbating the danger by impeding evacuation routes.
