Sammuttava

Sammuttava is a Finnish present active participle derived from the verb sammuttaa, meaning to extinguish, put out, or switch off. As an attributive adjective it describes something that extinguishes or is capable of extinguishing. In technical and safety language it is commonly used to refer to devices, systems or actions that perform extinguishing, for example sammuttava laite (an extinguishing device), sammuttava järjestelmä (an extinguishing system) or sammuttavat toimenpiteet (extinguishing measures).

The participle agrees with the noun in number and case, for instance sammuttavan laitteen (genitive singular) or sammuttavat laitteet (nominative plural). It is a standard part of Finnish grammar and is widely understood in engineering, safety and logistics contexts. The form is productive in creating compound expressions that denote functionality or capability related to extinguishing.

There is also a related form, sammuttettava, a passive or potential participle meaning “to be extinguished” or “that must be extinguished.” It is used in regulatory or instructional language to indicate something that should be extinguished. For example, phrases like sammuttettava tulipalo or sammuttavaa toimintaa appear in certain safety or maintenance contexts, though its usage is more specialized than sammuttava.

Related terms include sammutus (extinguishing, extinguishment) and sammuttaminen (the act of extinguishing). In practice, sammuttava and sammuttava-based compounds are most common in technical writing describing devices, systems and procedures designed to stop fires or halt a process.
