Erityiskäyttö

Erityiskäyttö is a Finnish noun meaning “special use” or “special application.” It refers to uses of a product, device, or substance that fall outside its standard or intended use and often require additional instructions, permissions, or safeguards.

The term is commonly found in technical documentation, safety data sheets, regulatory texts, and product labels. In these contexts erityiskäyttö signals that the item should be used only under specific conditions or for particular applications, such as in controlled environments, with special training, or with approved accessories.

Areas where erityiskäyttö may be noted include industrial machinery, software with restricted features or licenses, chemical products requiring controlled handling, and medical devices used for non-standard procedures. The exact scope and requirements of erityiskäyttö are defined by the manufacturer or the relevant regulatory authority and may include environmental limits, warning labels, or usage restrictions.

Etymology and nuance: erityiskäyttö combines eriyinen or eriyinen? with käyttö (use), reflecting a distinction between normal use and use that is considered exceptional or restricted. In Finnish regulatory and technical language, the concept helps clarify responsibilities for safe and compliant operation, guiding users to consult official documentation when a task could fall under special usage.
