syttyvien

Syttyvien is a Finnish term formed from the verb syttyä, meaning to catch fire. In everyday and technical usage, syttyvä describes something that is easily ignited, and syttyvien is the genitive plural form used in phrases like “syttyvien aineiden” to mean “of the flammable substances.” The related noun syttyvyys denotes flammability, the property of being able to ignite.

In Finnish safety language, the phrase syttyviä aineita or syttyviä nesteitä is common on labels, safety data sheets, and regulatory texts to identify materials that can catch fire easily. The usage mirrors international classifications of flammable materials, which group substances by ignition-related criteria such as flash point and burning characteristics. In formal regulation, such materials are categorized as flammable liquids, solids, or gases, with corresponding handling and storage guidance.

The term is widely applied in occupational safety, industrial hygiene, and fire safety contexts in Finland. It is used to describe a broad range of materials, including solvents, fuels, certain paints, and other substances that require precautions to prevent ignition sources. The Finnish vocabulary for safety also includes the abstract noun syttyvyys to discuss the property itself, and related phrases to specify the form in which ignition risk is present (for example, “syttyviä nesteitä” for flammable liquids).
