Low Flash Point Chemicals

Hazard: highly flammable


The following table lists some of the most common organic chemicals with low flash points (below 32 C), as measured by the Closed Cup method. These chemicals present a notable fire risk, which must be taken into account when planning work involving them. (Of course many other chemicals have similarly low flash points - this list includes just some of the more common ones.)
