Subject: Cooling Tower Hazards
Comments: To: ih**At_Symbol_Here**ls.eei.org
Good Afternoon,
I received a question this afternoon about potential hazards associated
with exposure to water vapor/mists from our mechanical draft cooling
towers at one of our electric generation plants. The plant is located on
a river and the cooling towers are used to cool the water before it is
discharged back into the river. It is a closed loop system so the river
water never comes into contact with any water in the system side.
Depending on weather conditions and wind direction maintenance workers
sometimes are exposed to water mist from the adjacent cooling towers.
Concern has been voiced about exposure to biological agents (i.e -
legionnaires, etc.) in these situations. Has anyone ever evaluated these
types of exposures in this situation or know of research that has been
done relative to this subject? Any good leads or ideas are gratefully
welcomed.
Thanks,
