Click on the appropriate area of the graph
to identify the volatility or dustiness of the substance.
Liquids - volatility: low, medium or high
You need the boiling point of your substance.
Find it in Section 9 of the Material Safety Data Sheet(MSDS) or under
Physical properties in the International Chemical Safety Card (ICSC).
In addition to the boiling point you will need to know the process temperature
at which the task is carried out.
Find the graph point that corresponds to both the boiling point and the process
temperature. It decides for the volatility of the liquid.
Solids - dustiness: low, medium or high
Low: Pellet like solids that don’t break up.
Little dust is seen during use e.g. PVC pellets, waxed flakes
Medium: crystalline, granular solids. When used, dust is seen,
but settles out quickly. Dust is left on surfaces after use e.g. soap powder.
High: fine, light powders. When used, dust clouds can be seen to form
and remain in the air for several minutes e.g. cement, carbon black, chalk dust.
