Also Known AsInflammable, combustible, fire hazard material

What is Flammable?

Flammable describes materials that ignite easily and burn rapidly. In chemistry and safety contexts, a flammable liquid is defined as one with a flash point below 60°C (140°F). The terms "flammable" and "inflammable" are synonymous — both mean easily set on fire. Flammable materials present fire and explosion hazards and require special storage and handling procedures.

Properties & Characteristics

Flash point: < 60°C (flammable liquid definition varies by standard). Lower Explosive Limit (LEL): minimum concentration for ignition. Upper Explosive Limit (UEL): maximum concentration for ignition. Autoignition temperature: temperature of spontaneous ignition without spark. Examples: ethanol (flash point 13°C), acetone (flash point -20°C), gasoline (flash point -43°C).

Uses & Applications

Fuel and energy production (gasoline, natural gas, ethanol). Industrial solvents (acetone, hexane, toluene). Chemical synthesis and manufacturing. Aerosol propellants. Printing and coating industries.

Safety Information

Store away from heat sources and open flames. Use approved flammable storage cabinets. Ground containers to prevent static discharge. Ensure adequate ventilation. Keep fire extinguisher (CO₂ or dry chemical) nearby. Never use near open flames. GHS Flame symbol required on containers.

Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
