second

Question 4

Staging key pumpers on hydrants enhances fire ground safety in several ways ? (3)

Answer 4

• Ensures an uninterrupted water supply
• Provides volume when needed

2 lines must be laid between the key pumper at the hydrant and forward pumper at the ladder.

Question 8

Engine mounted master streams flow

___ to ____ GPM

Answer 8

500 to 1000

Question 9

Engine mounted master streams should be considered for what 4 things?

Answer 9

• Structures that are well involved
• Beyond rapid reach of attack lines
• Exposure protection
• Situations that pose and unusual safety risk to fire fighters

Question 10

Attack Line Choice
The objective of the attack hose line choice is to provide enough What?

and to overcome the volume of fire being produced,
or adequate flow to effectively cool and protect what?

Answer 10

• enough GPM flow

- exposures

Question 11

When considering Basic Hose Line Placement, where should the 1st stream be placed?
Where should the 1st stream be placed when no life is endangered?
What is the purpose of the 2nd line?
What is the purpose of additional hose lines?
In Basic Hose Line Placement, what are four additional considerations for where lines should be positioned?

Answer 11

• between the fire and persons endangered by it
• between fire and most severe or unburned exposure
• 2nd line should protect a secondary means of egress
• Additional hose lines should cover other critical areas or when covered, back up in place hose lines
• Whenever possible lines should be positioned that direct support rescue activities, begins confinement, protect exposures, and control losses
