Ladder is not correctly supported and incorrectly angled. All non-self-supporting ladders should be secured at the top to prevent movement. Ladders should be placed at a 75 degree angle or a 4:1 ratio, base to the top support point. For a ladder that has a top support point of twenty foot, the base should be 5 feet from the wall.
Ladder does not extend 36 inches above landing point. No guard rails on scaffold, planking extends too far over supports. Bad housekeeping, particularly in area below scaffolding (fall hazard).
