Hazard warnings are important signals that inform people about potential dangers in their environment. These warnings can be found on products, in workplaces, or in public areas, and they often use symbols, colors, or text to convey risks. For example, a biohazard symbol indicates the presence of harmful biological substances, while a flammable label warns of materials that can easily catch fire. In addition to physical labels, hazard warnings can also be communicated through safety signs and alerts. These warnings help individuals take necessary precautions to avoid accidents or injuries. Understanding and recognizing these warnings is crucial for maintaining safety in various settings, such as construction sites or laboratories.
