As part of the law outlined in The Safety, Health, and Welfare at Work Act 2005 (S.I. No. 10 of 2005), measures are required to be in place to manage the risk of exposure to Legionella bacteria in the workplace.  

Under occupational Health and Safety legislation, there is a legal obligation on employers to carry out a risk assessment in relation to legionella prevention and control in the workplace and where a risk is identified the appropriate control measures should be put into place and a risk management plan adopted.
