What must be posted regarding floor load ratings?

• A. must be posted
• B. not posted
• C. posted only during inspections
• D. only for exterior floors

Answer: (A)

Floors have a maximum safe load, and the floor load rating communicates that limit to workers so they won’t place more weight on the surface than it can safely bear. If loads from people, equipment, or materials could exceed that capacity, posting the rating helps everyone see and respect the limit, reducing the risk of structural damage or collapse. This requirement applies wherever a floor has a defined load limit, in both interior and exterior areas, and it isn’t something that’s only done during inspections. So the correct practice is to post the floor load rating where applicable.
