Safety signals are indicators that help people recognize potential hazards in their environment. These signals can be visual, like warning signs or colored lights, or auditory, such as alarms and sirens. They are designed to alert individuals to take precautions or evacuate an area to avoid danger. In various settings, such as workplaces or public spaces, safety signals play a crucial role in emergency preparedness. For example, fire alarms notify occupants of a fire, while safety signs indicate areas that may be slippery or hazardous. Understanding these signals is essential for ensuring personal and public safety.
