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
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
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
Heavy bio films promote growth
Cooling Tower with Poor Maintenance
Dirty Fountain's
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
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
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

Interpreting your Legionella Test ResultsVERY 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
Source: Environmental Safety Technologies
Interpreting your Legionella Test ResultsLOW 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
Interpreting your Legionella Test ResultsMODERATE Risk Situation
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 disinfectionSource: Environmental Safety Technologies
Interpreting your Legionella Test ResultsHIGH Risk Situation
Legionella pneumophila SG1 1,000-5,000 CFU/ml
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 disinfectionSource: Environmental Safety Technologies
Interpreting your Legionella Test ResultsVERY 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 disinfectionSource: Environmental Safety Technologies
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?
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
Document in your CMMS
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
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
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.
