Hazard symbols are visual signs that communicate the dangers associated with certain substances or activities. They help people quickly understand the risks involved, such as toxic chemicals or flammable materials. These symbols are often found on labels of products like cleaning supplies, pesticides, and industrial chemicals, ensuring safety in homes and workplaces. Each hazard symbol has a specific meaning, often represented by a simple image, like a skull for toxicity or a flame for flammability. Understanding these symbols is crucial for anyone who handles hazardous materials, including workers in industries like construction or manufacturing, as well as everyday consumers.
