This Pipeline Disinfecting Safe Work Method Statement (SWMS) covers hazards and controls associated with disinfecting pipelines that will carry potable water.

It covers 12 job steps, from chlorine training, chemical storage and transport, weather checks, arrival on site and work area set-up, through environment, housekeeping and manual tasks, to water quality testing and injecting the mains, fuelling on-site, completion and emergency response.

It suits businesses and contractors involved in pipeline disinfection, particularly those dealing with potable water systems, and the safety officers and site supervisors overseeing high-risk construction work.
