Accident and injury rates are high in the construction industry, and there are no significant signs of occupational safety and health (OSH) development. The OSH interests, skills and knowledge of both employees and managers should be improved to gain long-lasting improvements. The Finnish construction industry has introduced a new safety training concept called Safety Training Park (STP) to meet these challenges. STPs consist of real-world training points and use new multimodal and innovative safety training methods aimed at stimulating both individual behaviour change and quality change in overall conditions that ultimately aims to lead to improved safety performance at both the construction site and organisational levels. This study focuses on the Safety Training Park in northern Finland (STPNF). STPNF has been designed, constructed and financed during a collaboration process that includes more than 80 organisations. In order to contribute to the discussion regarding sustainable work reaching from the employee level to the organisational level and beyond, STPNF is discussed both from microergonomic and macroergonomic perspectives.
