Which safety control can assist in directing the behavior of individuals in an area?

The correct choice is signs. Signs are a crucial safety control that help communicate important information and instructions to individuals in a specific area. They can direct behavior by providing clear guidance on safety protocols, hazards, and required actions, helping ensure that individuals are aware of their surroundings and know how to act accordingly.

For example, a "Wet Floor" sign alerts individuals to exercise caution, reducing the likelihood of accidents. Similarly, directional signs can help guide people to safety exits during an emergency. Since signs convey visual information directly to those present in an area, they play an essential role in maintaining safety and promoting desired behaviors.

Training programs and personal protective equipment (PPE) are also important for safety but focus more on preparedness and personal safety measures rather than active direction of behavior in an immediate environment. Incident reports, while valuable for understanding past issues and preventing future occurrences, do not guide behavior in real-time.
