Scaffolding is an essential part of construction projects, providing workers with the necessary support to work at heights. However, working on scaffolding poses risks that require proper safety measures. One of the most effective ways to ensure worker and public safety is by using scaffolding signs. These signs provide clear instructions, warnings, and safety guidelines that help prevent accidents and injuries.
In this article, we’ll explore 20 common scaffolding signs, their meanings, and why they are crucial in maintaining a safe worksite.
