Document that systems were drained and cleaned
• Developing an operation strategy for systems that will be operational but at lower demands such as cooling towers, swimming pools, hot tubs or decorative fountains
For Example – Cooling towers
Develop an operational strategy for circulating all cooling tower basins on a regular basis (every two to three days) while feeding biocides (chlorine, bromine, etc) and documenting residuals in towers.
For Example – Decorative Fountains
Develop an operational strategy for operating fountains on a regular basis (once per day for several hours) while feeding biocides (chlorine, bromine, etc) and documenting residuals in fountains
• Identify other water equipment that may be present such as • Water softeners • Carbon or Activated Charcoal filters •
Safety showers/eye washes – note that some sites may continue to test these on a regular basis so additional flushing may not be necessary
• Develop a time-line to regenerate water softeners 1 to 5 days prior to re-occupancy • Develop a time-line to backwash or replace carbon or activated charcoal filters 1 to 5 days prior to re-occupancy • Test/flush safety shower and eye washes prior to re-occupancy 1 to 5 days prior to re- occupancy
Validate water system by testing for Legionella
• Perform a Legionella test on cooling tower systems and decorative fountains o This can be done by submitting samples to a local laboratory (like EMSL, or EMLab P&K) note that there is a 10 day turn around for this testing or it can be completed using an on-site test that returns results in 45 minutes.
