Which color indicates flammability in hazard classification?

The color red is specifically used to indicate flammability in hazard classification systems. This association stems from established guidelines in safety and hazard communication, where red serves as a universally recognized warning sign for fire hazards. In various settings, materials or substances that pose a flammability risk are often marked in red to ensure that the potential for fire or explosion is immediately recognizable to anyone working in or around those environments.

Understanding the color-coding system is crucial for maintaining safety and awareness in workplaces handling hazardous materials. For example, when individuals see red labeling or markings, they should take extra precautions and be prepared for fire-related dangers.
