Demonstration should include using appropriate conduct and safety procedures while
- using aluminum ladders (e.g., three-point contact)
- carrying ladders (e.g., two people at all times)
- erecting and setting ladders
- identifying types of ladders and the components and safety features of each (e.g., wall or straight, extension, roof, attic, special-purpose, solid-beam, wood/aluminum, wood/aluminum truss, fiberglass).
Process/Skill Questions:
- Why are ladders rated for certain weights?
- Why is the apex (i.e., highest point) of a stepladder not considered a step?
- Why are aluminum ladders considered unsafe for electrical work?
