What does the color blue indicate on hazardous warning labels?

The color blue on hazardous warning labels signifies a health hazard. This indicates that exposure to the material can pose health risks to individuals, such as acute or chronic effects including skin irritation, respiratory issues, or other health-related dangers. Understanding this color coding is crucial for personnel to identify and respond to potential health risks while handling hazardous materials. It aids in ensuring safety protocols are followed and informs individuals of necessary precautions to take when working around or with the substances indicated on such labels. This color system is part of the Globally Harmonized System (GHS) of Classification and Labeling of Chemicals, which provides a standardized approach to hazard communication.
