DEPARTMENT OF HEALTH 5. CLEANING As required under the NT Food Act 2004, all water carter equipment must be maintained in a clean and sanitary condition. This equipment includes the lining of the tank, openings, lids, seals, hoses, fitting and pipes. The cleaning process involves the removal of dirt, followed by sanitising to reduce the number of disease-causing microorganisms. The water tank/container must be cleaned and sanitised regularly. Containers and equipment that have not been used for some time will need to be cleaned and sanitised prior to use. Water tanks not being used should be drained air-dried and the inspection hatch left partly open until use. Tanks should be cleaned at a minimum every three months, by: 1. Physically cleaning the tank/container with detergent and flushing with clean water. 2. Sanitising by, (a) spraying the surfaces with a solution containing 10 mg/L free available chlorine, leaving it for 5 minutes and than rinsing off with drinking water, or (b) filling the tank with a solution containing 5 mg/L of free available chlorine, leaving for at least 30 minutes before draining and rinsing the tank with drinking water. Pipes, fitting, hoses and similar should be cleaned at a minimum monthly with a solution containing 5 mg/L of free chlorine, using the following steps: 1. Physically cleaning the equipment with detergent followed by flushing with clean water. 2. Sanitising pipes or hoses by filling them for at least 30 minutes with a solution containing 5 mg/L free available chlorine, and than rinsing them with clean water. 3. Sanitising fittings by soaking them in a solution containing 5 mg/L of free available chlorine for 5 minutes followed by rinsing with clean water. 4. Drain and air-dry equipment and store in a manner protecting them from contamination. Note: The water carter should ensure that the disposal of wash water does not cause a nuisance. For advice on wash water disposal contact the Department of Natural Resources, Environment, the Arts and Sport (NRETAS). Page 8 of 10 Department of Health is a Smoke Free Workplace
