Standardised symbols

The ‘Standardised symbols’ section is a compilation of symbols and signs whose use is limited. The ISA symbol is standardised, but it has been declared free for anyone to use. Generally, standardised pictograms must be licensed for a fee. For some symbols or signs, there are specific requirements that must be fulfilled before they can be used, and permission to use them must be sought from the body administering them.

This section gives the body responsible for each symbol and sign so that you can ask them for further information and requirements for use.


ISA symbol
ISA symbol. The icon shows a person sitting in a wheelchair against a blue background.

ISA stands for International Symbol of Access, the universal symbol for persons with reduced mobility.

The ISA symbol is used for instance to label a step-free entrance to a building, an accessible WC or parking spaces for the disabled. It may also be used to indicate a step-free access route or accessible service (e.g. the way to the lifts or an accessible dressing room at a sports facility).

The official ISA symbol may be used on a blue or black background. The symbol may be reversed.

A print-ready file of the ISA symbol can be found on the accessibility pages of the Finnish Association of People with Physical Disabilities. There is also further information there on the development and use of the symbol.

Induction loop
Induction loop. The icon shows an ear in the middle and a small letter T at the bottom, against a white background.

The international symbol for an induction loop may be found in the ETSI standard ETSI EN 301 462, ‘Symbols to identify telecommunications facilities for deaf and hard of hearing people’.

A print-ready version of the induction loop symbol is available from the Finnish Federation of Hard of Hearing.

Plain language logo
Plain language logo. The icon shows a black, S-shaped arrow, against a white background.

The plain language logo designates a plain-language book or magazine, signage or website.

In order to use the plain language logo, you must obtain permission from Selkokeskus (the plain language centre). The logo must be accompanied by a descriptive text: plain-language book; plain-language magazine; plain-language signage; plain-language website.

For more information on the plain language logo and how to obtain permission to use it, contact Selkokeskus (

Emergency exit sign

Emergency exit. The icon shows an arrow pointing to the left on the left side and a person running through a door on the right, against a green background.

Source: SFS-ISO 3864-1

An emergency exist sign may be found for instance in the standard SFS 5715, ‘Fire protection. Safety signs’. The standard is available for sale from the Finnish Standards Association SFS.

More information on how to mark emergency exits may be found in the relevant Decree of the Ministry of the Interior.

Signs marking an accessible emergency exit may be accompanied by the ISA symbol. However, it is worth remembering that in case of a fire, for instance, an accessible emergency exit cannot require the use of a lift.
