Static electricity in solvents
WebOct 29, 2024 · Static electricity occurs when charge builds up in one place. Typically, objects are neither positively or negatively charged—they experience an overall charge of zero. … WebBoth combustible and flammable liquids can easily be ignited by a flame, hot surface, static electricity, or a spark generated by electricity or mechanical work. Highly volatile solvents are even more hazardous because any vapor (VOCs) released can reach ignition sources several feet away.
