Which color indicates flammable liquids in the Globally Harmonized System (GHS) labeling?

In the Globally Harmonized System (GHS) labeling, the color that indicates flammable liquids is red. This system is designed to convey the hazards associated with chemicals effectively through standardized symbols and colors. Red is universally recognized as a warning color, primarily associated with fire and danger. Therefore, it is used to signify substances that pose a fire risk, such as flammable liquids. The use of red helps ensure that those handling these materials can quickly identify potential hazards, which is crucial for safety in various environments, including workplaces and emergency response settings.

Other colors in the GHS labeling system have specific meanings; blue typically indicates health hazards, green signifies non-hazardous materials, and yellow is often associated with caution. Understanding these color codes is essential for anyone involved in handling hazardous materials, ensuring that they can respond appropriately to risks.
