DIVISION 11

An open metal framework for supporting insulated electrical conductors.

DIVISION 4

What is the minimum fire resistive rating for a firewall under BP 220?

A continuous path of travel from any point in a building to the outside at ground level.

Division 15

This is the term that refers to a component or mastic installed in an opening through a floor or wall to retard the passage of fire.

A steel or plastic tube through which electrical wiring is run.

DIVISION 8

A louver shaped so as to distribute air about a room.

This type of fireproofing is usually applied on structural steel members, mostly in a thick layer. This is also cheaper as compared to other options, but is very crude and aesthetically unpleasant. Moreover, if the environment is corrosive in nature, then this option is not advisable, as there is the possibility of water seeping due of its porous nature, and thus difficult to monitor for corrosion.  What is this type of fireproofing?

DIVISION 13

These materials usually have a large concentration of organic matter that is reduced by fire to ashes. In the case of silicone, organic rubber surrounds very finely divided silica dust. When the organic rubber is exposed to fire it burns to ash and leaves behind the silica dust with which the product started.  In this characteristic, silicone is described as

During a fire test, materials like gypsum wallboards or concrete walls are sacrificial and become "spent" over time while exposed to fire. Given sufficient time under fire or heat conditions, these products char away, crumble, and disappear. The idea is to put enough of this material in the way of the fire that a level of fire-resistance rating can be maintained. Concrete and gypsum materials are described as

Division 16

These materials have substances that swell as a result of heat exposure thus increasing in volume and decreasing in density.  In passive fire protection systems, these materials are used in a form of coating or mastic that expands to form a stable, insulating char when exposed to fire.  These materials are said to be

Which type of mechanical ventilation system causes the lowering of air pressure inside the house such that outdoor air is drawn in?

Division 5

Firestop components include, among others, the following materials except one.

Which of the following speaks true of the efficiency relationship between natural lighting and artificial (measured in terms of “cool white fluorescent” or CWF) lighting? 

Division 2

.    Once occupied, units in medium- and high-rise residential buildings are eventually fitted out according to a unit owner’s preference.  Which fit-out activity presents the least possible changes, if none at all?

A vertical panel of non-combustible or fire resistive material attached to and extending below the bottom chord of the roof trusses, to divide the underside of the roof into separate compartments so that heat and smoke will be directed upwards to a roof vent.

Division 12

This term refers to the fire-resistant material inserted into a space between a curtain wall and a spandrel beam or column, to retard the passage of fire through the space.

The space between the ceiling of a room & the structural floor above, used as passage for ductwork, piping, & wiring.
