Water Hygiene Cooling Tower Assessment

A cooling tower risk assessment is legally required for all premises with cooling towers and evaporative condensers. The requirement to carry out a risk assessment is laid down in section 6 of the Control of Substances Hazardous to Health Regulations 2002, and section 3 of the Management of Health and Safety at Work Regulations (1999).

In order to give clear guidance and instruction on how to comply with the regulations, the Health and Safety Executive has issued an approved code of practice ACOP L8, which details all the specific tasks, checks, policies and procedures which need to be in place for any organisation to fully comply with the legislation.

A cooling tower risk assessment carried out by the S2 Partnership will detail all the relevant assets, plant and systems on site which have the potential to create a risk with regard the growth and dissemination of Legionella bacteria. A condition survey of all relevant plant/assets will summarise the remedial actions required in order to reduce the risk to a manageable level. In addition, the S2 Partnership will audit all current activities on-site with regard to Legionella control as per ACOP L8 and set up a comprehensive management plan and water hygieneThe growth of bacteria in water systems is a common cause of potentially-fatal Legionnaires’ disease.  Recent outbreaks of Legionella have highlighted the need for stringent water hygiene risk mana... More log book system to include detailed policies, procedures and method statements in order to ensure the site fully complies with all guidance and legislation.

What are the benefits?

A water hygiene risk assessment carried out by the S2 Partnership provides a number of benefits including:

  • compliance with relevant legislation – specifically HSWA (1974), COSHH (1992), MHSWR 1999, The Notification of Cooling Towers and Evaporative Condensers Regulations 1992;
  • prevention of an occurrence/outbreak of Legionnaires’ disease. Legionnaires’ disease can be fatal and as such if negligence is proved, a prosecution under the Corporate Manslaughter and Corporate Homicide Act 2007 is a distinct possibility. Cooling Towers have been associated with all of the largest outbreaks of Legionnaires’ disease;
  • maintaining the company’s reputation. Following recent outbreaks of Legionnaires’ disease, public awareness and media involvement continues to gain momentum; and; and
  • the control of Legionella bacteria on sites is closely scrutinised by both the HSE and the Local Authority. These agencies have the power to issue Improvement Notices and Prohibition Notices. Following all of the guidance outlined in an S2 Partnership risk assessment will ensure that audits by the HSE and Local Authority run smoothly and avoid the detrimental effects of having either a Prohibition or Improvement Notice served.
