Guardrails
Guardrails should be installed on all scaffold platforms in accordance with required standards if more than 10 feet (3.1 m) above the ground or floor. Guardrails should at least consist of top rails, midrails and toeboards.
Guardrail height - The height of the toprail for scaffolds manufactured and placed in service after January 1, 2000 must be between 38 inches (0.97 meters) and 45 inches (1.1 meters). The height of the toprail for scaffolds manufactured and placed in service before January 1, 2000 can be between 36 inches (0.91 meters) and 45 inches (1.1 meters).
Crossbracing - When the crosspoint of crossbracing is used as a toprail, it must be between 38 inches (0.97 m) and 48 inches (1.2 meters) above the work platform.
Midrails - Midrails must be installed approximately halfway between the toprail and the platform surface. When a crosspoint of crossbracing is used as a midrail, it must be between 20 inches (0.51 meters) and 30 inches (0.76 m) above the work platform.
Release - To ensure adequate protection, install guardrails along all open sides and ends before releasing the scaffold for use by employees, other than the erection and dismantling crews.
Exceptions - Guardrails are not required, however, in the scenarios below.
- when the front end of all platforms are less than 14 inches (36 cm) from the face of the work
- when outrigger scaffolds are 3 inches (.8 cm) or less from the front edge
- when employees are plastering and lathing 18 inches (46 cm) or less from the front edge
Materials - Steel or plastic banding must not be used as a toprail or a midrail.
