Online interactive Risk Assessment (OiRA) is a web platform that enables the development of sectoral risk assessment tools in any language in an easy and standardised way. OiRA partner countries can use OiRA to develop their own sector-specific risk assessment tools aimed at micro and small enterprises (MSEs). The tools help MSEs to identify and evaluate their safety and health risks and propose preventive actions in relation to the identified risks. Finally, OiRA tools can be used to generate risk assessment reports. Such risk assessment reports are mandatory in all European Union Member States.
