Editor's Notes
- #7: Cal OSHA: “A fixed ladder is a ladder permanently attached to a structure, building, or equipment. “
- #9: Performance work = need to reach out or move frequently
- #10: Access work: use ladders to reach upper working levels
- #11: Top support condition = condition of the building or edge of the roof.
- #16: Non-self supporting ladders must be placed at a proper angle. The foot/base of the ladder should stand 1 foot out from the wall for every 4 ft up.
- #18: Ladder will take a corner before you do.
