The definition
OSHA defines flash point as "the minimum temperature at which a liquid gives off vapor in sufficient concentration to form an ignitable mixture with air near the surface of the liquid."
Where to find it
OSHA says Section 9 of a Safety Data Sheet, Physical and Chemical Properties, lists flash point.
What it is not
This is our note, not OSHA's: a flash point is a property of the liquid. It is not a pouring or mixing temperature. Use the makers' instructions for those.
Read the fire section too
OSHA says Section 5 of the SDS covers fire-fighting measures, including which extinguishing equipment is suitable and which is not.
FAQ
General information only. Never leave a burning candle unattended, and keep it at least 12 inches from anything that can burn. When you heat wax, stay with it, and turn off the heat if you leave or see smoke. Never use water on a wax fire. If you can do so safely, slide a lid over the pot and turn off the heat; if the fire does not go out, get everyone out and call 911 from outside. Read and follow the Safety Data Sheet and instructions from the maker of every wax, wick, fragrance oil, and dye you use.
