Legionnaires' Disease
Steven G. Liescheidt, P.E., CSI-CCS, CCPR.
Overview
Legionnaires' disease is a common name for one of the several illnesses caused
by Legionnaires' disease bacteria (LDB). Legionnaires' disease is an infection
of the lungs and is a form of pneumonia. More than 43 species of Legionella have
been identified and more than 20 have been linked with human diseases.
Legionellosis is the term for the diseases produced by LDB. In addition to
Legionnaires' disease, the same bacteria also cause a flu-like disease called
Pontiac fever.
In
this course, the student will learn the causes of Legionnaires' disease and some
of the methods used to detect an outbreak. In addition, the student will learn
about symptoms of the disease and high risk people who are more likely to be
susceptible to Legionnaires’ disease. Finally, methods are discussed to
mitigate the likelihood of developing Legionnaires' disease in building systems,
such as cooling towers, hot water heaters and water distribution systems.
The student is expected to read and review the material contained in
Legionnaire’s Disease – U.S. Department of Labor - OSHA Technical Manual (www.dol.gov).
The
student must take a multiple-choice quiz consisting of twenty-four (24) questions at
the end of this course to obtain PDH credits.
