What does HMIS stand for in chemical labeling systems?

HMIS stands for Hazardous Material Identification System. This terminology is essential in the context of chemical safety and labeling. The HMIS provides a system for identifying the health hazards, flammability, and reactivity of chemicals through a color-coded labeling system. Each label includes numerical ratings to communicate the level of risk associated with the material in question. This helps ensure that workers are informed about the dangers of the chemicals they might encounter, which is critical for maintaining safety in the workplace.

The other answer choices do not accurately reflect the standard used in chemical labeling systems. The focus on "identification" of hazardous materials is a fundamental aspect of OSHA standards and helps guide users in understanding appropriate safety measures and response actions.
