7. Duties under other regulations
Reporting cases of legionellosis
Under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR), you must report any cases of legionellosis in an employee who has worked on cooling towers or hot and cold water systems that are likely to be contaminated with legionella.
Notification of cooling towers or evaporative condensers
Under the Notification of Cooling Towers and Evaporative Condensers Regulations(NCTEC), you must notify your local authority in writing if you have a cooling tower or evaporative condenser on site, and include details about where it is located. You must also tell them if or when such devices are no longer in use.
Notification forms are available from your local authority or environmental health department.
Dry/wet coolers or condensers
Dry/wet coolers or condensers do not rely solely on the principle of evaporation, so these systems may not require notification under NCTEC. However, it is important to assess the system against the notification requirements defined in NCTEC, for example where such systems spray water directly onto the surface of the heat exchanger.
You can find HSE guidance on dry/wet cooling systems.
