zapalnym

Zapalnym is the instrumental singular form of the Polish adjective zapalny, meaning flammable or easily ignited. It is used to describe substances that can catch fire under normal conditions. In safety and technical texts, zapalny and łatwopalny are common synonyms, though łatwopalny is widely used in everyday language and regulatory labeling.

In regulatory and safety contexts, the concept of zapalny is tied to the classification of hazardous materials. The European Union framework for chemical safety, rooted in the CLP Regulation, classifies substances and mixtures that can ignite as flammable and requires specific labeling and handling precautions. Polish safety data sheets and labels may refer to a substance as zapalny or używać terminu łatwopalny to convey the same risk. Labels emphasize keeping such materials away from heat, sparks, and open flames, ensuring proper ventilation and storage in appropriate containers.

Zapalny can apply to liquids, with many common solvents and fuels being described as zapalny, as well as to solids that can burn readily, such as certain powders or aerosols. The term also encompasses various ignition scenarios, including vapor-formed or dust-explosion risks, where flammable conditions can arise under certain circumstances. Proper risk assessment, storage solutions, and adherence to regulatory guidelines are essential when handling zapalny substances.

Etymology and usage notes: zapalnym appears in phrases where the noun is in instrumental or related grammatical cases, and it reflects the broader concept of materials that pose fire hazards. See also terms such as zapalny materiał and substancje łatwopalne for related safety terminology.
