Safety as an integrated process
We do not treat the service as a set of formal documents.
ET-KO Ltd. is a registered occupational health service that has supported employers in managing workplace health and safety since 2008. Our approach combines medical, organisational and legal expertise to deliver practical solutions based on each organisation’s activity and specific risks.
We provide ongoing support as well as assistance when activities change, an inspection is upcoming, an official instruction has been received or specialised consultation is required.
Dr Virginia Hvarchilkova
Head of ET-KO Ltd. Occupational Health Service.
