What physical data is typically NOT included on a safety data sheet (SDS)?

What physical data is typically NOT included on a safety data sheet (SDS)?

• A. the material appearance and odor
• B. the maximum contaminant level (MCL), the recommended MCL (RMCL) and MCL goal (MCLG)
• C. the molecular weight, boiling point, melting point, viscosity, and water solubility for the material
• D. the chemical formula

Answer: (D)

Safety data sheets present information you can observe or measure to understand how a material behaves. Appearance and odor, boiling and melting points, viscosity, water solubility, and related properties are all classic physical data because they describe how the substance actually behaves under different conditions. The chemical formula, while essential for identifying the substance, isn’t a property you measure to characterize its physical behavior; it’s a structural descriptor of the molecule. So it belongs to identity or composition information rather than the physical data section. Regulatory levels like maximum contaminant levels aren’t physical properties either; they’re regulatory context, not physical behavior.
