The Safety Investigation Authority of Finland (SIAF or SIA, Finnish: Onnettomuustutkintakeskus, lit. Accident Investigation Center, shortened to OTKES; Swedish: Olycksutredningscentralen) is the accident investigation authority of Finland. It investigates all major accidents, and all aviation, maritime, and rail accidents and incidents. SIAF is located within the Ministry of Justice, and is headquartered in Helsinki, Finland.

The SIAF was previously known in English as the Accident Investigation Board of Finland.

Organization

The SIAF consists of five investigation branches: aviation, maritime, rail, other accidents, and exceptional events. The SIA has appointed a chief investigator to each.

Maritime The investigation of accidents and dangerous situations that take place
on Finnish territorial waters or in which a Finland-based vessel is involved.
Risto Haimila
Rail The investigation of especially hazardous accidents that happen either in
rail, metro, or tram traffic, such as level crossing accidents, rolling stock
fires, and train collisions.

Other accidents The Other accidents-branch investigates serious accidents that pose a risk to life or that cause significant economic or environmental harm. Kai Valonen

The SIAF has investigated four of such events during its history: the Jokela school shooting (2007), Kauhajoki school shooting (2008), death of 8-year-old Eerika [fi] (2012), and Turku stabbing (2017).
