Any occupancy that is subject to CADS hazard display should be __________________.
inspected annually.
The 20-min rule applies to ______________ and _______________, and only these two types of construction.
Class 3 - Ordinary Construction
Class 5 - Wood Frame
Class 2 (non-combustible), are the __________________ in terms of collapse when exposed to fire.
least stable
Class 3 (ordinary construction): this is how the majority of ______________ are made.
brick buildings
Class 3 ordinary construction consists of masonry or other noncombustible walls with a _______________.
2hr fire resistance rating.
Class 4 (heavy timber) interior columns, beams, and girders are ___________, and the floors and roofs are of _______________.

In theory 1 gallon of water will provide sufficient cooling to quench approx _________ at the average rate of surface burning.
5lbs of fuel
Most residential rooms have a fire load of ______________.
5 lbs per sqft.
The method of attack most often used in the free burning stage is the ________________, which initially consists of sweeping the ceiling with the stream in a side-to-side or clockwise circular motion. This ceiling level attack is only done for __________ seconds.
combination method, 5-10
The _______________ violently disturbs the thermal balance , rendering this method unsuitable for interior firefighting in occupied buildings.
indirect method
Disadvantages of a combination attack include putting members within an extremely ____________, and that it requires ____________ to develop a high degree of proficiency.
hostile enviorment, live-fire training
Each gallon of water can expand to _____________ gallons of steam when fully vaporized.
1,500-2,000
Basic requirements for an indirect attack:
- __________ conditions throughout the area.
- Limited _________ of the fire area.
- A point on the perimeter in which to make a small opening for the injection of a _________ into the superheated atmosphere.
- High heat
- ventilation
- 30 degree fog pattern
4 Key requirements for an indirect attack:
- No __________
- _________ ventilation
- High _______
- Limited size of the _______________
- Occupants
- Limited
- heat
- potential fire area
**(NOT NEED SUFFICIENT VENTILATION)**
Disadvantages of the indirect attack method:
- It cannot be used in an ______________.
- The presence of ventilation openings will _______ the effect of the stream.
- A discharge of less than the ______________ can push fire ahead of the stream, an effect that may not be observed from the outside.
- It isn’t possible to view the interior layout until you have ____________ of the situation.
- Using the indirect method can increase ________________.
