3.1.1 Guidelines to Keep a Clean System and Prevent Micro-organism Growth
l
Perform a risk assessment of the water system using a competent person, and implement an appropriate
monitoring and control program.
l
Connect a RO system to a clean, potable main water supply.
l
Ensure that the system is cleaned and/or flushed regularly.
l
Ensure that the buffer tank is clean and sterile before use.
l
Enter a service contract that suits the needs of the company.
l
Stop the system if polluted drinking water is found in the area.
l
Avoid water temperatures above 68 °F (20 °C). Temperatures between 20-60 °C (68-140 °F) favor the
growth of Legionella.
l
Do not stop the system unless it is faulty or leaking (to avoid water stagnation).
l
If the power to the system is interrupted (such that the unit fails to flush or drain) for more than 48 hours,
complete a total system disinfection.
l
Refrain from closing sections of the system, unless there is a leakage or fault (to avoid water stagnation).
l
Disinfect at least once per year, and after every maintenance or repair.
l
Analyze the water and test for harmful bacteria at least once per year.
l
Conduct follow-up measurements until the system is clean if bacteria has been detected in the system.

3.2 Risk Monitoring and Assessment
Water hygiene assessments must be performed at the site to determine the risk and severity of hygiene hazards
that affect the health and safety of the public. Performing a risk assessment with regular monitoring will allow
procedures to be adjusted.
Ensure that the person conducting the assessment is qualified.
A typical assessment inspects the following:
l
Supply water quality. Refer to "Water Supply" on page 19 .
l
Environment around the humidifier.
l
Maintenance procedures. Refer to "Maintenance Procedures" on page 43 .
l
Water pre-treatment options (such as using UV light, using reverse osmosis or deionized water, etc.).
Proper maintenance procedures along with recommended site controls will help ensure compliance to local
regulations and protect the public.
It is recommended to monitor the humidification system weekly, and then monthly once satisfactory levels are
maintained.
