What are the four main sections of the MSDS Hazard Diamond and what does each section stand for?

The MSDS (Material Safety Data Sheet) Hazard Diamond consists of four main sections, each represented by a color-coded quadrant. The blue section indicates health hazards, with a scale from 0 (no hazard) to 4 (deadly). The red section represents flammability hazards, also rated from 0 to 4. The yellow section denotes reactivity hazards, while the white section is used for specific information, such as personal protection requirements or additional hazards.
