Site were regularly having positive Legionella samples from their Process System. Poor system management and site didn’t understand their roles and responsibilities under the ACoP L8 and HSG 274.
After a Risk Assessment was carried out it was determined that a full system disinfection of the services be carried out, site staff to be suitably trained and a weekly pasteurisation of the system be carried out.
We now carry out regular sampling for Legionella Bacteria. We completed a Legionella Awareness training course for the site staff and implemented a new written scheme and control measures and the system in compliant.
