Chapter 12 Flashcards
Townhomes are a type of single-family dwelling that is structurally independent from adjacent single-family dwellings and separated by a common fire-resistive-rated wall assembly.
12
Void fires in combustible buildings may consume structural support members and lead to collapse.
12
Multifamily dwellings include row houses and garden apartments.
12
Reflex time, or the amount of time it takes to react and take action, is usually much higher in high-rise buildings than in non-high-rise buildings.
12
Basement or below grade fires can be extremely difficult to control and extinguish once they are past the incipient stage.
12
Observing the position of the neutral plane at the first floor entryway door of a building might indicate a basement fire.
12
An observable indication of a basement fire can be smoke filling an entire first floor door opening of a structure without the presence of a neutral plane.
12
During a suspected basement fire, the risk analysis should consider the firefighter safety issues prior to placing personnel above the basement level.
12
The application of a water spray pattern that cools the hot gases is the most effective way to control a basement fire.
12
Salt water should not be used on live electrical equipment.
12
Unlike a typical electrical or gas utility, on a PV array there is no point of disconnect.
12
When illuminated by artificial light sources such as fire department light trucks or an exposure fire, PV systems can produce electrical power sufficient to cause a lock-on hazard.
12
Attic fires are typically ventilation-limited due to limited natural ventilation openings.
12
If lightweight truss construction is exposed to fire and no rescue operations are required, a defensive strategy is highly recommended as early collapse is likely.
12
Knee wall construction creates interconnected concealed spaces where the wooden structural members provide a relatively large surface area of exposed fuel along with air flow conductive to spreading fire.
