Flash Points - Liquids
The flash point of a chemical substance is the lowest temperature where enough fluid can evaporate to form a combustible concentration of gas.
The flash point is an indication of how easy a chemical may burn. Materials with higher flash points are less flammable or hazardous than chemicals with lower flash points.
Some liquids and their flash points at atmospheric pressure:
