Question 20

Book 100 High Rise Manual

In the event of a high rise fire, the danger to building occupants could develop from three sources.

1 - there is the possibility that occupants could be directly exposed to the actual fire.

2 - the possibility that a panic could result from the knowledge or belief that a fire is in progress in the building.

3 - the gravest threat to building occupants in high rise fires is exposure to smoke and the products of combustion.

Answer 20

Question 21

Book 100 High Rise Manual

Fire Attack

The best way to protect high rise occupants from smoke and fire is to control the fire rapidly, which is best achieved through the properly operating fire protection systems.

A quick, aggressive attack combined with proper ventilation offers the best means of containing the products of combustion and the spread of fire, and thereby affords building occupants the greatest degree of protection.

The fire attack may have to be delayed until control of the stairwell used for fire attack has been established above the fire floor in order to ensure exiting occupants will not be exposed to the products of combustion.

Question 37

Book 100 High Rise Manual

Standpipe pressure in a high-rise building is controlled by three means: pressure regulating devices, pressure restricting devices, or orifice plates.

The Pressure Regulating devices control pressure, and assuming they are functioning properly, the volume of a give outlet can increase to supply more than one line, as long as the g.p.m. does not exceed the set limit which is normally ___ g.p.m.

Pressure Restricting devices work by restricting to flow by how far the valve can be opened, thereby reducing the flow and the p.s.i.

The orifice plate controls pressure by restricting volume and is limited to its design requirements for supplying ___ g.p.m.

Answer 37

300

200

Question 38

Book 100 High Rise Manual

Lines connected to orifice plates require that the orifice plate be removed and a member remain at the outlet. If an orifice plate cannot be removed, lines should not be completely shut off at the nozzle.

Question 44

Book 100 High Rise Manual

Stairshafts in high-rise buildings constructed after 1974 are required to employ a shairshaft ventilation system. Pressurization fans, that function when the sprinkler or smoke detector systems are activated, are required to provide a uniform air velocity within each enclosed stairshaft.

The fans must provide not less than ___ cubic feet per minute while maintaining a positive pressure of not over ___ lbs. on interior doors.

Answer 44

50

25

Question 45

Book 100 High Rise Manual

Stratification of smoke and fire gases occurs as heat and smoke travel vertically within a building. These products of combustion will rise through any available vertical opening, cooling as they rise, until the temperature is equal to the temperature of the surrounding air. When stabilization of the temperature occurs, smoke and fire gases will form layers or clouds within the building. This stratification of smoke and fire gases generally serve as a “lid” for other products of combustion which will tend to bank down below the stratified smoke and horizontally spread to other portions of the building.

Answer 45

reference

Question 46

Book 100 High Rise Manual

Mushrooming is a condition caused by smoke and fire gases that cannot vertically escape a building. Smoke and fire gases will rise to the highest level possible and then begin to bank down and fill all available spaces
