Subpart M (26) pg 41
Falling Objects:
a. Where the potential exists for an object to fall from a person, building, structure, or equipment due to circumstances which require the object to be located at, near, above, or beyond the installed falling object protection (e.g., toe-boards, screens, mesh, etc.) additional positive control measures shall be implemented to prevent the object from falling to any lower level. The duty and cost of implementing additional controls shall be the responsibility of the Subcontractor creating the hazard. Examples of additional control measures include, but are not limited to, lanyards, debris nets, and catch basins.
b. Where overhead work is taking place, such as steel erection, decking, welding, bolting up, etc. and it is not feasible to implement a positive control measure, the entire area below the operation that could be potentially impacted from a falling object(s) shall be completely barricaded and the necessary number of spotters needed to control the area shall be assigned to stand outside the barricaded area to prohibit access to the area while a falling object hazard exists.
c. Screens, panels, or similar must be installed where objects have the potential to fall to from an upper level down to a public area.
