Don’t park directly behind internal slide ladder rack. How many feet
20’ so they can get 20’ str8 or 35’ extension
Ladder Climbing Angle
About 65-75 Degrees
Quick formula to get 75 Degree Angle
Place the base of the ladder at a distance from the vertical plane equal to 1/4 the total working length of the ladder.
Placed at a window
Tip shall be level with window sill.
Placed at a roof
- Tip shall be at least 2 feet above the roof or parapet.
Placed alongside a fire escape on a building wall
Tip shall be 1 to 3 feet above the fire escape railing.
Placed against a fire escape
Tip shall be slightly above the fire escape railing.
The butting member places their
Left foot in the center of the bottom rung of the ladder and maintains a downward pressure
If a member is working off one side of the ladder
The butt firefighter moves their foot from the center of the bottom rung of the ladder to the side opposite the one from which the firefighter is working,
Force that causes the outward slippage of the butt
Increases as member ascends the ladder
If the aluminum portable ladder is to be left unattended,
It should be secured at the tip by the first member that climbs the ladder.
If a tool is carried, it should be
Balanced in the carrying hand, which holds onto the side of the beam. The free hand continues to grasp the underside of the beam.
Do not carry the tool close to the body or inside the ladder over the rungs
The Leg Lock:
Need to Vent window on ur right side - Use Left leg to lock
Two Rungs above the one u are Standing on
Using the Personal Harness:
The snap hook of the personal harness hooks directly to the ladder rung.
Used in a Tower Ladder Basket
See Lad 6 Sec 3.6.2
Portables can also be used to
Bridge a Fence
Support opened overhead doors
ice covered ponds, lakes, etc. for rescues.
Bridging caved-in excavations where a person is partially buried.
Generally, floor and ladder working length are:
4th floor -
3rd floor -
2nd floor -
4th floor - 35’ extension ladder.
3rd floor - 24’ or 35’ extension ladder.
2nd floor - 24’ extension ladder or 14’ “A” Frame ladder.
Ladder Placement for venting window from a Portable w member on ladder.
Upwind from Window to be vented. The tip of the ladder, if possible, should be level with, or higher than the top of the window.
The preferred ladder for burnt out stairs
Extension Ladder
Do not climb higher than
The third rung from the top on either straight or extension ladders.
Defect in Ladder
Notify the Fire Tools and Equipment Unit for collection, repair or replacement.
Do not lower the ladder by pulling the butt end further away from the building. Why?
-Doing so will reduce the load capacity as the angle decreases.
- There is a greater possibility that it will unlock the lock assemblies in the upper
section.
-Always lower the fly ladder below the desired level and re-raise to the proper height to ensure a safe, 65-75 degree climbing angle and proper locking action of the lock assemblies.
When operations are to be conducted at electrical generating stations or substations,
Under NO circumstances shall metal ladders or tools be brought inside the gates. Lad 1 Sec 12
