• Employers must provide fall protection when an unprotected side or edge is four feet or more above a lower level, with some exceptions.

Employers are required to protect employees when an unprotected edge or side is four feet or more above a lower level.

Hoisting areas are any elevated opening that allows equipment or materials to be raised or lowered to another walking-working surface.

If the hoisting area or other edge is four feet or more above the lower level, employers must protect employees from falls by using:

• Guardrail systems
• Personal fall arrest systems
• Travel restraint systems

If a guardrail system is used but needs to be removed while the equipment or materials are being transferred, OSHA requires that any employee who is required to lean through or over the edge must wear personal fall protection.
