Mark Cullen

Assistant Chief Executive Officer - Operational Compliance and Prevention Division (OCPD)


The Operational Compliance and Prevention Division initiates and delivers prevention, enforcement, and compliance based programmes with a focus on those sectors and activities where the risks of fatality, injury or ill health are highest and where employer awareness and observed compliance is lowest. This is achieved through the implementation of health and safety initiatives that are based on direct workplace interventions, national campaigns and working partnerships with representative stakeholder groups. Activities include the development and provision of information, guidance and advice to employers and employees co-ordinated with targeted nationwide inspection programmes, enforcement and market surveillance.

Yvonne Mullooly

Assistant Chief Executive Officer - Chemicals and Prevention Division (CPD)


The Chemicals and Prevention Division leads and delivers on prevention, enforcement, and compliance programmes across a range of sectors, products and risks. It provides guidance on the safe and sustainable management of chemicals in the workplace, in the environment, and when used by consumers. The prevention programmes focus on the collection and analysis of data, the development of legislative proposals, the implementation of health and safety initiatives in specific workplaces, as well as the provision of information and guidance to employers and employees. Businesses are helped through the Taking Care of Business programme, which includes the online tool, the Authority's e-Learning portal at HSA Learning and Work Positivecl. The division also operate the REACH/CLP Helpdesk for Ireland, and represent the Authority at various EU, ECHA, OECD and UN committees.
