Demonstrate safe laddering techniques.
Demonstration should involve using appropriate conduct and safety procedures while using aluminum ladders (e.g., three-point contact), while carrying ladders (e.g., two people at all times), and when erecting and setting ladders (e.g., four to one rule). Identification of additional ladder types may include
- wall (straight) ladder
- extension ladder
- roof ladder
- attic ladder
- special purpose ladders (e.g., "A" ladder, folding ladder, pompier ladder)
- solid beam ladder
- truss beam wood ladder
- aluminum ladder
- wood and aluminum truss ladder
- fiberglass ladder
and the parts and safety features of each.
Process/Skill Questions:
- Why are ladders rated for certain weights?
- Why is the apex (highest point) of a stepladder not considered a step?
- What is the four-to-one rule?
