Dan Weimar is the Manager
of Business Development Engineering for Chem-Aqua, a global water treatment
company headquartered in Irving, Texas. Over the course of his 36 year career,
his primary focus has been steam plant operations and cooling systems with a
heavy emphasis in the last 20 years on water and energy conservation. Dan
is a past voting member of ASHRAE’s Technical Committees, TC 3.6 for Water
Treatment and TC 8.6 for Cooling Towers/Evaporative Cooling as well as past
Chair of the TC 3.6 Handbook Committee for Water Treatment.
Mr. Weimar’s presentation
will be “ASHRAE 188 Legionellosis – Risk Management Strategies”.
Legionnaires’ disease is a form of pneumonia, which principally affects the
elderly (especially males), smokers, dialysis patients and people whose defense
systems are impaired. The Centers for Disease Control (CDC) estimates
that in the U.S. there are about 8,000 to 18,000 cases of Legionnaires’ disease
every year, with about 3,000 reported. It is caused by the inhalation of aerosolized
water droplets of breathable size (1 – 5 µm) contaminated by the infectious
strains of Legionella bacteria. Legionella bacteria can be found in
natural water sources (rivers, lakes, or streams), mud, and soil samples. It
has been isolated from environmental water sources such as evaporative
condensers, cooling towers, air handling equipment and humidifiers.
Legionella can also be found in potable water sources such as shower heads,
water fixtures and ice machines.
