Answer
Brief Explanations:
When there is moving equipment below an open - sided floor or platform that requires a standard railing, a toe - board is typically included in the railing system to prevent small objects from falling onto the moving equipment below. A safety net may not be part of the standard railing, a warning sign is not part of the railing structure, and a handrail is a general part of the railing but not the specific addition when there is moving equipment below.
