Safe walking surfaces on concrete structural members.

You must not use structural members with studs, dowels, or shear connectors installed on the top side as a walkway and/or means of access unless such studs, dowels, or shear connectors are covered with suitable material and in such a manner as to provide a walking surface at least as stable and free of hazards as the top surface of the member would provide without attachments installed.
Note:
For the purpose of this section, "stud" means all protruding metal attachments to structural members.
