If you accidentally evaporate all of the water, you can reconstitute the slurry by. Flammable – The symbol for this is a flame and it pertains to chemicals or highly flammable gases that may catch fire or ignite once exposed to air or other ignition sources or elements. Therefore, the lower a substance's flash point, the more hazardous it is. A flammable symbol is used to highlight a chemical or substance that could easily catch fire if exposed to naked. 2. Inflammable substances have higher fume strain because of which flash point diminishes and combustibility increment in inflammable substances are exceptionally flammable. 2. This entry applies to typical non-lithium dry batteries (alkaline, nickel metal hydride, nickel cadmium, etc. While this varies greatly depending on the material, flammable substances usually have a flash point of below 37. 3. 3.
