Flammable liquids are substances that can easily catch fire and burn when exposed to heat, sparks, or flames. Common examples include gasoline, alcohol, and paint thinners. These liquids have low flash points, meaning they can ignite at relatively low temperatures, making them dangerous if not handled properly. To ensure safety, it's important to store flammable liquids in appropriate containers and away from heat sources. Always read labels and follow guidelines for use. In case of a spill, it's crucial to act quickly and safely, as flammable liquids can create hazardous situations, especially in enclosed spaces like garages or basements.
