Which chemical classification system focuses on the identification of hazards using a color-coding scheme?

The classification system that focuses on identifying hazards using a color-coding scheme is HMIS (Hazardous Materials Identification System). HMIS utilizes a color code along with numerical ratings to convey information about the health, flammability, and physical hazards of chemicals. The color-coded labels help workers quickly assess the levels of risk associated with different materials, allowing for safer handling and usage.

While GHS (Globally Harmonized System) and NFPA (National Fire Protection Association) also aim to communicate hazards, their methods differ. GHS uses a more standardized labeling system that includes symbols and signal words without a distinct color-coded numerical rating like HMIS. NFPA employs a diamond hazard rating, where each color represents a different type of hazard, but its focus isn’t purely color-coding as a method for identification like HMIS does.

Therefore, HMIS stands out for its specific use of a color-coding scheme for hazard identification, making it a crucial system for safety in workplaces dealing with hazardous materials.
