A solvent's flash point is the lowest temperature at which it gives off enough vapour to ignite near an open flame or spark. It's the single number that most determines how a flammable solvent needs to be stored and handled.
What Flash Point Actually Tells You
A low flash point means the solvent can form an ignitable vapour-air mixture at or near normal room temperature — acetone, MEK and many of our other light solvents fall in this category. A higher flash point means the liquid has to warm up considerably before vapour ignition becomes a risk, which changes how much ventilation and ignition-source control a given storage area actually needs.
Storage Basics for Flammable Solvents
- Store away from all ignition sources — open flames, sparking equipment, and anything that generates static discharge.
- Keep storage areas ventilated so vapour can't accumulate to a flammable concentration.
- Use grounding/bonding when transferring solvent between containers to prevent static discharge igniting vapour.
- Store in appropriately rated containers and cabinets, separated from oxidizers (see our guide on chemical storage compatibility).
- Keep quantities in the work area to what's needed for the shift — bulk stock belongs in a dedicated flammables store, not the shop floor.
Products Where This Applies Directly
Most of our solvents and organic chemicals carry a flammability hazard to some degree — acetone, toluene, xylene, IPA, ethyl acetate and MEK among them. Check the specific product's SDS for its exact flash point and handling requirements before storing or scaling up use.
