What information is NOT provided in Section 3 of the MSDS, Physical State?

Section 3 of the Material Safety Data Sheet (MSDS), which is now often referred to as Safety Data Sheet (SDS), provides crucial information regarding the physical and chemical properties of a substance. This section typically includes the physical state of the material, which can be categorized as solid, liquid, or gas.

The physical state descriptor helps users understand how to handle the material safely and the potential hazards associated with it. In addition to identifying whether a material is a solid, liquid, or gas, Section 3 also typically covers specific properties such as boiling point and freezing point, as well as vapour pressure, which provide further insight into the material's behavior under different temperature and atmospheric conditions.

Flammability characteristics, however, are generally discussed in other sections of the SDS, such as Section 4 (Fire and Explosion Data) or Section 5 (Fire Fighting Measures). Therefore, while information about boiling point, freezing point, and vapour pressure are directly related to the material's physical properties and included in Section 3, flammability characteristics are not part of this section. Understanding this distinction helps ensure that users are aware of how to locate and interpret the safety features and risks associated with various chemicals effectively.
