10. Legionella Overview
 Overview
 Waterborne bacteria
 Must have water
 Is in all surface waters, groundwater, waste waters,
soil and compost
 Conditions for Growth
 Thrives when protected in bio-film (slime)
 Needs iron and l-cysteine (non-essential amino acid)
 Can live inside amoebas and other protozoan

11. Legionella Overview
 Since its prime growth amplification is in 77°F to
113°F water, it can grow rapidly in HVAC and
tempered water environments.
 Resistant to low levels of Chlorine
 Some rubbers and some plastics promote growth

12. Recognizing Risk Factors
 Disease causation REQUIRES all:
 Live bacteria
 Amplification of colonies
 Body of contaminated water
 Means for forming respirable droplets (1 – 5 microns into
lower lung) from the water
 Exposure of susceptible host
 Prevent any one of above, and infection will not
occur

13. Heavy bio films promote growth

14. Cooling Tower with Poor Maintenance

15. Dirty Fountain's

16. Recognizing Risk Factors
 Growth occurs in piping dead legs, tank bottoms,
sumps, on pan surfaces, on splash fill in towers, in
whirlpools, fountains, etc.
 How would you clean an outdoor fountain pool?
 Cleaning a cooling tower

17. Employer risk
 Workers who must service, repair, or clean the
equipment
 Splashing waters, spraying, pressure washing, using
rotary tube cleaners
 Employers have much information available from OSHA
website - www.osha.gov
 Know the condition of the water with good treatment
program that includes testing
 Test the waters and the biofilm, to have a defensible
testing program

18. Protecting Employees and Students/Public
 Liability for employees, Students or public
 Defensible program such as outlined in ASHRAE 188
 Chemical water treatment in place and adequately
maintained
 Periodic testing will help protect people and defend your
organization

25. Interpreting your Legionella Test Results
VERY LOW Risk Situation
 Legionella pneumophila SG1 10 CFU/ml
AND/OR
 Legionella pneumophila SV 2-14 & Legionella non-pneumophila species < 100 CFU/ML
Action Steps
 Very low level of health concern – background levels of
Legionella
 Review location of Cooling Tower in relation to susceptible
population
 Review current biocide treatment program
 Schedule regular testing for Legionella in the future

26. Interpreting your Legionella Test Results
LOW Risk Situation
 Legionella pneumophila SG1 10-99 CFU/ml
AND/OR
 Legionella pneumophila SV 2-14 & Legionella non-pneumophila species 100-999 CFU/ml
Action Steps
 Low level of health concern – Legionella well below the level
associated with outbreaks of Legionnaires’ disease
 Disinfection of the Cooling Tower is generally not recommended
unless located near susceptible populations
 Review current biocide treatment program
 Schedule regular testing for Legionella in the future
Source: Environmental Safety Technologies

27. Interpreting your Legionella Test Results

 Legionella pneumophila SG1 100-999 CFU/ml
AND/OR
 Legionella pneumophila SV 2-14 & Legionella non-pneumophila species 1,000-4,999 CFU/ml
Action Steps
 Moderate level of health concern – Legionella approaching the level
associated with outbreaks of Legionnaires’ disease
 Disinfection of the Cooling Tower is usually indicated as a precaution
against any further Legionella amplification
 Review current biocide treatment program
 Schedule an immediate re-test for Legionella to determine
effectiveness of disinfection

AND/OR
 Legionella pneumophila SV 2-14 & Legionella non-pneumophila species 5,000-10,000 CFU/ml
Action Steps
 High level of health concern – Legionella at level associated with
outbreaks of Legionnaires’ disease
 Immediate disinfection of the Cooling Tower is indicated
 Alter the current biocide treatment program
 Schedule an immediate re-test for Legionella to determine
effectiveness of disinfection
Source: Environmental Safety Technologies

29. Interpreting your Legionella Test Results
VERY HIGH Risk Situation
 Legionella pneumophila SG1 >5,000 CFU/ml
AND/OR
 Legionella pneumophila SV 2-14 & Legionella non-pneumophila species >10,000 CFU/ml
Action Steps
 Significant potential for causing an outbreak of Legionnaires’
disease
 Immediate disinfection of the Cooling Tower is indicated
 Alter the current biocide treatment program
 Schedule an immediate re-test for Legionella to determine
effectiveness of disinfection

30. Selecting a Chemical Treatment Provider
 Suggested questions to ask:
 What type of biocide program are you treating my tower
with?
 Is my cooling tower being physically cleaned at least
once a year?
 Are we doing any Legionella testing and if so what is the
frequency?

31. Develop a Strong PM plan
 Inventory all possible sources
 Document in your CMMS
 Efficient tracking of all work done
 Create preventative maintenance tasks required
and schedule ongoing work
 Attach chemical treatment reports for easy review
 Be sure to review all reports before filing

32. Document in your CMMS

33. New and Existing State/Local Requirements
 Educate yourself of the requirements in your State
 Cooling tower regulations in New York
 Hospitals regulated in MD & NY
 Alleghany County, PA
 Garland, TX
 New regulations constantly emerging due to
increased awareness

34. Where can I go for help!
 ASHRAE Standard I88-2015
 Environmental Safety Technologies
 Cooling Technology Institute
 Center for Disease Control
 Your local Brady Trane Franchise Office or trusted
HVAC provider
 Your water treatment provider

35. On a personal note
 If you or someone you know uses a CPAP machine…
remind them to follow the cleaning procedures and
know the type of water to use in the machine.
