  • Cal OSHA: “A fixed ladder is a ladder permanently attached to a structure, building, or equipment. “
  • Performance work = need to reach out or move frequently
  • Access work: use ladders to reach upper working levels
  • Top support condition = condition of the building or edge of the roof.
  • 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.
  • Ladder will take a corner before you do.
