of the PPE to avoid adding to the thermal load of the wearer. Information on any secondary risk should also be included here.
See also Section 5 – Fire fighting measures of the SDS for specific fire/chemical PPE advice.

3.9 Section 9 – Physical and Chemical Properties
This section of the SDS describes the physical and chemical properties of a hazardous chemical. The data should apply to the hazardous chemical as supplied. If the hazardous chemical is a mixture, the physicochemical data should describe the mixture. If that information is not available, the properties of the most relevant ingredients should be provided.
The following properties should be included in the SDS where relevant and the appropriate units
of measure and/or reference conditions should be specified:
    * Appearance (physical state, colour etc)
    * Odour
    * Odour threshold
    * pH
    * Melting point/freezing point
    * Initial boiling point and boiling range
    * Flash point
    * Evaporation rate
    * Flammability (solid, gas)
    * Upper/lower flammability or explosive limits
    * Vapour pressure
    * Vapour density
    * Relative density
    * Solubility
    * Partition coefficient: n-octanol/water
    * Auto-ignition temperature
    * Decomposition temperature
    * Viscosity
If relevant, the interpretation of the numeric value and the method of the determination should
also be provided. Where there is no information about specific characteristics or data available,
a statement should be included to that effect. It is not appropriate to leave blank spaces or use
the term 'N/A' in an SDS.
In addition to those listed above, other physical or chemical parameters relevant to health and safety should be included in this section of the SDS. This includes parameters which, in addition to chemistry, can significantly influence the properties of chemicals, for example size or surface area in the case of engineered nanomaterials. Examples of parameters which may be included are:
    * Specific heat value
    * Saturated vapour concentration (include reference temperatures)
    * Release of invisible flammable vapours and gases
    * Particle size (average and range)
    * Size distribution
    * Shape and aspect ratio
    * Crystallinity
    * Dustiness
    * Surface area
    * Degree of aggregation or agglomeration, and dispersibility
    * Redox potential
    * Biodurability or biopersistence
    * Surface coating or chemistry (if different to rest of particle).

3.10 Section 10 – Stability and Reactivity
This section of the SDS provides information regarding the stability and reactivity of the hazardous chemical. Information on the possibility of hazardous reactions is necessary to ensure the safe handling and storage of chemicals and to ensure effective fire fighting and spill control measures.

Reactivity
This section should describe the reactivity hazards of the chemical, including the conditions under which the hazardous reactions may occur, for example:
    * whether the hazardous chemical will react or polymerise
