Containers with classified chemicals.
The SDS must describe the properties of classified chemicals on site.

Section 9: Physical and Chemical Properties – This section identifies physical and chemical properties associated with the substance or mixture. The minimum required information consists of:

  • Appearance (physical state, color etc.)
  • Upper/Lower flammability or explosive units
  • Odor
  • Vapor pressure
  • Odor threshold
  • Vapor density
  • pH
  • Relative density
  • Melting/freezing point
  • Solubility(ies)
  • Initial boiling point & boiling range
  • Flash point
  • Evaporation rate
  • Flammability (solid, gas)
  • Partition coefficient: noctonol/water
  • Auto-ignition temperature
  • Viscosity

Section 10: Stability and Reactivity – This section describes the reactivity hazards of the chemical and the chemical stability information. This section is broken into three parts: reactivity, chemical stability, and other. The required information consists of:

  • Reactivity – Description of the specific test data for the chemical(s).
  • Chemical stability – Indication of whether the chemical is stable or unstable under normal temperature and conditions. Description of any stabilizers. Indication of any safety issues should the product change in physical appearance.
  • Other – Indication of the possibility of hazardous reactions and conditions under which hazardous reactions may occur. List of all conditions that should be avoided. List of all classes of incompatible materials. List of any known or anticipated hazardous decomposition products.

Section 11: Toxicological Information – This section identifies toxicological and health effects information or indicates that such data are not available. The required information consists of:

  • Information on the likely routes of exposure. The SDS should indicate if the information is unknown.
  • Description of the delayed, immediate, or chronic effects from short- and long-term exposure.
  • The numerical measures of toxicity – the estimated amount of a substance expected to kill 50% of test animals in a single dose (LD50).
  • Description of the symptoms. This description includes the symptoms associated with exposure to the chemical including symptoms from the lowest to the most severe exposure.
  • Indication of whether the chemical is a potential carcinogen.

Sections 12-15 – Note: Since other Agencies regulate this information, OSHA does not enforce Sections 12 through 15.

Section 16: Other Information – This section indicates when the SDS was prepared or when the last known revision was made. The SDS may also state where the changes have been made to the previous version. You may wish to contact the supplier for an explanation of the changes. Other useful information also may be included here.
