Chapter 7 Flashcards
Compartmentation is the ability to contain a fire to an area to limit the growth and spread of fire and smoke to other areas of a structure.
7
Compartment size is a factor in determining fire spread within each type of construction.
7
Construction finishes can have a high or low thermal mass, which can affect the ability of a compartment to absorb and hold heat energy. This can affect the fire growth rate.
7
Part of the structural evaluation and the ability to contain or limit fire spread of a fully developed fire is an assessment of the protective features within the structure.
7
Electric hazards should be assumed during all phases, especially during aerial and ground ladder placements.
7
Stack effect is the movement of air into and out of buildings, chimneys, flue gas stacks, or other containers, resulting form air buoyancy.
7
Buoyancy occurs due to a difference in indoor to outdoor air density resulting from temperature and moisture differences.
7
Stack effect is usually associated with tall buildings due to the numerous leakage paths, shafts, and ductwork that are compounded by operational practices and occupant behavior when opening and failing to close doors.
7
Stack effect can be used to great advantage in clearing stairwells during high-rise operations and even more so in winter conditions.
7
Most common type III structures have a masonry exterior enclosing a wood frame.
7
The vast majority of type V construction is residential construction.
7
An often used green initiative is photovoltaic solar panels to generate electrical power.
7
Even if the PV system is disconnected, a PV module will always generate electricity when the sun shines.
7
A stand alone photovoltaic system is not connected to power grid.
7
A grid interactive photovoltaic system is connected to the grid and may contain solar panels, combiner boxes, charge controls, and inverters.
