Answer 1

Velocity and shape

Question 2

What are the three main categories of nozzle

Answer 2

Hand lines
Master Streams
Specialty

Question 3

What type of nozzle is the Akron Sabrejet

Answer 3

Co-axial
(smoothboar and fog)

Question 4

Akron Sabrejet solid stream

Answer 4

44mm
-24mm tip
- 700 lpm @ 350 kpa nozzle pressure

65mm
- 29 mm tip
- 1000 lpm @ 350 kpa nozzle pressure

Question 5

Akron Sabrejet fog

Answer 5

400 lpm @ 350 kpa nozzle pressure

Question 6

Task Force tips nozzle
High rise nozzle
bumper line
trash line

Answer 6

Solid stream with 38 mm ball valve

24 mm tip

Question 7

What is a master stream

Answer 7

Any fire stream that is too large to be controlled without mechanical aid

Question 8

Blitzfire discharge elevation and pivot from center

Answer 8

10-50 degrees elevation
20 degrees pivot from center

Question 9

Blitzfire valve type

Answer 9

slide valve

The valve handle must be fully closed to reset the safety shut-off mechanism. Placing the monitor on a tilted surface (greater than 10 degrees) may cause a failure in resetting the safety shut-off. The safety shut-off valve can be overridden by holding the valve handle in an open condition.

Question 10

Blitzfire stacked tips

Answer 10

24mm
32 mm
38 mm

900-1950 lpm at 550 kpa nozzle pressure

Question 11

Blitzfire fog tip

Answer 11

Standard pressure; 700 kpa
Low pressure; 420 kpa

Up to 120 degree wide fog pattern

Question 12

Blitzfire Operation

Answer 12

If possible, do not use the monitor on a hard surface such as a paved road or a concrete sidewalk. Secure the monitor to a stationary object. Monitor may not be left unmanned unless firmly secured to a stationary object and is within sight of the engine operator.
The monitor’s reach of stream is most effective at 35 degrees of elevation. Care must be taken when operating below 35 degrees due to nozzle reaction.
