What is the primary function of warning signs on scaffolding?

The primary function of warning signs on scaffolding is to indicate load limits and safety instructions. These signs are essential for ensuring the safety of workers and the public by providing crucial information about the maximum weight the scaffolding can support and specific safety protocols that need to be followed. This helps prevent accidents and injuries by ensuring that users are aware of the risks and limitations associated with the scaffolding.

In this context, while informing the public about ongoing work is important, it is not the primary purpose of the warning signs. Similarly, guiding scaffolding design and displaying the scaffolding company’s name may have relevance but fall outside the immediate safety function that warning signs are meant to fulfill. The focus on load limits and safety instruction is vital to maintaining a safe working environment on construction sites.
