What is an effective way to provide visual warnings about excavation hazards?

Using brightly colored cones and signs is an effective way to provide visual warnings about excavation hazards because they are highly visible and can quickly draw attention to areas that may be dangerous. Bright colors, such as orange and red, are universally recognized as warning signals, helping to alert workers and passersby of potential risks. This proactive approach not only helps prevent accidents but also ensures that all individuals in the vicinity are aware of the excavation site and can take appropriate precautions. The use of cones and signs complements safety practices by conveying clear, immediate information about the presence of hazards, thereby enhancing overall safety for everyone involved.
