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 I. What is Legionnaires' disease? - Learn about disease symptoms, transmission, diagnosis, and treatment Legionnaires' Disease
Section II. What water systems in workplaces are potential sources of Legionnaires' disease? - Source identification and control procedures - Water sampling guidelines
Water sampling guidelines
Section III. How to determine if a workplace is experiencing an outbreak - Investigation protocols
Section IV. What actions are required when an outbreak of Legionnaires' disease has been confirmed? - Outbreak response

How do I find out about employer responsibilities and worker rights?

Workers have a right to a safe workplace. The law requires employers to provide their employees with working conditions that are free of known dangers. The OSHA law also prohibits employers from retaliating against employees for exercising their rights under the law (including the right to raise a health and safety concern or report an injury). For more information see or worker rights.

OSHA has a great deal of information to assist employers in complying with their responsibilities under the OSHA law.

OSHA can help answer questions or concerns from employers and workers. To reach your regional or area OSHA office, go to OSHA's Regional & Area Offices webpage or call 1-800-321-OSHA (6742).

Small business employers may contact OSHA's free and confidential On-site Consultation program to help determine whether there are hazards at their worksites and work with OSHA on correcting any identified hazards. Consultants in this program from state agencies or universities work with employers to identify workplace hazards, provide advice on compliance with OSHA standards, and assist in establishing injury and illness prevention programs. On-site Consultation services are separate from enforcement activities and do not result in penalties or citations. To contact OSHA's free consultation service, go to OSHA's On-site Consultation web page or call 1-800-321-OSHA (6742) and press number 4.

Workers may file a complaint to have OSHA inspect their workplace if they believe that their employer is not following OSHA standards or that there are serious hazards. Employees can file a complaint with OSHA by calling 1-800-321-OSHA (6742), online via eComplaint Form, or by printing the complaint form and mailing or faxing it to your local OSHA area office. Complaints that are signed by an employee are more likely to result in an inspection.

If you think your job is unsafe or you have questions, contact OSHA at 1-800-321-OSHA (6742). It's confidential. We can help. For other valuable worker protection information, such as Workers' Rights, Employer Responsibilities, and other services OSHA offers, visit OSHA's Workers' page.

This eTool is a chapter of the OSHA Technical Manual developed to assist OSHA staff in evaluating workplace hazards. eTools are "stand-alone," interactive, Web-based training tools on occupational safety and health topics. As indicated in the disclaimer, this eTool is not an OSHA standard or regulation, and it creates no legal obligations. Likewise, the eTool does not eliminate or limit any obligations that may be created by the OSH Act or by OSHA standards or regulations.
