A substance that can burn and ignite is classified as flammable. Flammable substances have the ability to catch fire easily at relatively low temperatures, demonstrating that they can ignite under common conditions. This characteristic is critical in the context of safety and handling, especially in environments where fire hazards are a concern.

In contrast to flammable materials, corrosive substances damage or destroy living tissue or severe corrosion of materials. Reactive substances, on the other hand, engage in chemical reactions that may lead to a release of energy in the form of heat or gas, but they do not necessarily ignite on their own. Oxidizing agents support combustion and may cause flammable materials to ignite, but they are not inherently flammable themselves. Understanding the distinctions between these categories is essential for ensuring safety in various practical applications and environments.
