First aid symbols are visual representations used to convey important information about medical assistance and safety. These symbols help people quickly identify first aid kits, emergency procedures, and medical equipment. Common symbols include the Red Cross, which signifies medical help, and the first aid kit symbol, indicating where supplies can be found. Understanding these symbols is crucial in emergencies, as they guide individuals in providing assistance or seeking help. For example, the AED symbol indicates the presence of an Automated External Defibrillator, a device used in cardiac emergencies. Recognizing these symbols can save lives by ensuring prompt action.
