What hazard does the blue label communicate?

The blue label signals a reactivity hazard related to water. Materials with this labeling are moisture-sensitive and can react violently when exposed to water or moisture, often releasing toxic gases. That’s why the emphasis is on keeping them dry, storing them in moisture-free and compatible containers, and handling them with precautions to avoid any contact with water or humidity. This is different from hazards indicated by other colors or labels. For example, a label pointing to highly pressurized gases focuses on pressure-related risk; corrosive materials require warnings about corrosive damage to skin, eyes, and metals; and non-flammable solvents pertain to flammability concerns.
