What aspect of workers' safety do safety signs and tags primarily address?

Safety signs and tags play a crucial role in communicating hazards in the workplace. They are designed to alert workers and visitors to potential dangers present in the environment, thereby promoting awareness and caution. By providing clear and concise information regarding the type of hazard—such as electrical, chemical, or physical risks—these signs and tags facilitate informed decision-making and behaviors among employees.

Effective hazard communication through visual cues helps to reduce the likelihood of accidents and injuries by ensuring that all individuals on site understand the risks they may encounter. This proactive approach is a key component of establishing a safe working environment, as workers are more likely to adhere to safety protocols when they are clearly informed about potential hazards.

The other options, while relevant to aspects of workplace safety, do not directly address the primary purpose of safety signs and tags as effectively as hazard communication does. Identifying tools pertains to equipment usage, preventing unauthorized access relates to security measures, and delivering training focuses on knowledge transfer rather than immediate on-site hazard awareness.
