Legionnaires' Disease
This eTool is designed to assist industrial hygienists in the assessment of worksites for potential Legionnaires' disease. It provides information on disease recognition, investigation procedures to identify probable water sources, and control strategies. The majority of legionellosis is caused by Legionella pneumophila, and so this eTool will deal exclusively with that organism. Diseases in which other species of Legionella are involved should be dealt with in a similar manner.

Section II. What water systems in workplaces are potential sources of Legionnaires' disease? - Source identification and control procedures - Water sampling guidelines
