The warnings and essential safety information required by law must be supplied with civil masks. It is not sufficient to provide this information only in electronic form, such as on the company’s website. Section 4 of the Government Decree on information to be supplied with consumer goods and services (Valtioneuvoston asetus kulutustavaroista ja kuluttajapalveluksista annettavista tiedoista, 613/2004) contains a more detailed definition of information that may be essential for safety.
