A - ADVANCED fire on arrival
L - LARGE volume of water needed to cool superheated fire area
L - LARGE area of fire in a large UNCOMPARTMENTED area
A - AREA or size of fire is unknown

- Officer on Duty = Review each tour member works. Initial in Red ink
- Commanding Officer = Review monthly. Initial in Red ink

Minimum safe operating distances for applying water on Energized or De-Energized Electrical Components
138 kV 345 kV
30º or greater Fog 15’ 25’
Streams
Straight Or Solid
Streams and 75’ 125’
Streams <30º Fog
- NOTE: Multiply by 5 for straight or solid streams and streams less than 30º Fog
- The primary means of applying water to energized equipment is through the Tower Ladder
Types of Outside Streams
- Hand Lines
- Deckpipes
- Ladder pipes
- Tower Ladder Streams
- Fireboat Streams
- Satellite Water Monitors
Situations which may call for the use of Outside Streams
- To protect life by putting a stream between the fire and the occupants
- To protect exposures
- To confine the fire
- To diminish heavy fire so that an interior attack can be made
- NOTE: Only the IC may order the use of Outside Streams
- NOTE: As a general rule, outside streams should not be directed into occupied structures. Two exceptions exist:
1. To protect people on a fire escape
2. Heavy fire in a store
Rear Tenements
- Rear tenements are small in area
- Frame or non-fireproof construction
- Range in height from 2 to 5 stories
- Distance between front and rear building is usually 10’ to 25’
- Often not visible from the street
- often occupied by elderly people
Command Post Location for High Rise Multiple Dwelling
Establish a location best suited for the ICP. If other than the Lobby, notify dispatcher and all incoming units
Manifold
-Carried by Satellite Units
-Portable - can be wheeled by 1 member OR carried by 2 members
-Operated remotely from 2,000 GPM pumper and Satellite apparatus
-Supplied by 5” hose
-Four 2½” outlets
-Two 3” outlets
-Placed in front of building or courtyard for
H-Types
-Equipped w/ Ross Relief Valve
How high do firewalls go?
1916-1929 - Ceiling of top floor
1930-1940 - Underside of Roof boards
After 1940 - Top of Roof boards
Trench Cuts
- A Trench cut is a defensive operation
- Trench cut at least 3 feet wide
- Trench cut about 20 feet from initial vent hole
- Trench may be cut but should not be opened until adequate opening over the fire
- Two or more inspection holes are cut on fire side of trench
- All personnel off the roof on fire side of trench
- A charged line should be in place on the roof
Apparatus Speed Restrictions
- 3” speed hump = 20 MPH
- 4” speed hump = 15 MPH
- Turning corners: not in excess of 15 MPH
- with Snow chains on: no more than 30 MPH
Expansion of heated Steel
- An average 50’(foot) length steel beam, heated to 970ºF will extend in length approximately 4”(inches)
- Longer “I” beams expand a proportionately greater distance
- As the temperature increases, the rate of expansion increases
- At 1000ºF, a 100’(feet) long beam will extend in length 9½”(inches)
- Cooling a heated Steel beam will cause it to regain its strength and load carrying ability
