Contractors are required to provide fall protection for any worker six feet or more above a lower level who is not on a ladder or scaffold. This can be accomplished with "conventional" fall protection – guardrails, safety nets and personal fall arrest systems – or with a custom solution engineered for the particular job. If workers are on ladders or scaffolds, other requirements come into effect.
