Define the 3 P’s:
Plumbing - checking the ‘L’ shaped sticker along with the position of the firefighter footing the ladder and ensure the ladder is not leaning to one side
Projection - distance of the base from the vertical objective is 1/4 the height of the extended height

(5) Considerations necessary for safe sitting of a ladder:
- Height - will the height of the ladder achieve what we need?
- Projection - Can we achieve the required projection with the height of object and height of ladder?
- Plumbing - Can we put the ladder up in such a way that it won’t tip left or right?
- Clearances - Are there any branches, power lines, tress etc. in the way?
- Ground Condition - Is the ground slippery or uneven?
Inspection and Maintenance of ladders:
Division A:
If a ladder appears to have any damage, or does not conform to checks, complete a P798 Form (Damaged or Missing Equipment / Uniform Report) and notify OIC
Division B:
Any identified damage or faults on Div B ladders should be reported to the shift LFF or SO
