[0002] Fire safety awareness displays play a vital role in promoting public awareness of fire safety. With the acceleration of urbanization and the increasing complexity of building structures, fire hazards are also increasing. Fire safety awareness displays aim to disseminate fire safety knowledge and skills to the general public. These displays typically take various forms, such as community bulletin boards featuring graphic illustrations of fire hazards, preventative measures, and escape methods. In public places like schools and shopping malls, electronic displays play looping fire safety videos. Through vivid images and practical examples, they provide a more intuitive understanding of how to properly use firefighting equipment and protect oneself in a fire.
