Legionella

What Is Legionella?

Legionnaires’ disease,  a severe form of pneumonia, poses a serious health risk to everyone. Originating  from Legionella bacteria, outbreaks typically occur in systems where water is  stored or used, creating ideal conditions for bacterial growth, such as in hot  and cold-water systems, ventilation systems, cooling towers, and evaporative  condensers. The disease is contracted through inhaling small droplets of contaminated water containing  Legionella bacteria. Conditions favouring Legionella growth include water  temperatures between 20-45 °C, deposits supporting bacterial growth like rust or  sludge, and water storage or recirculation. Aerosolized water droplets from  sources like showers also poses a risk. Certain groups are at  higher risk, including individuals over 45, smokers, heavy drinkers, those with  weakened immune systems or chronic respiratory/kidney diseases, and those with  diabetes, lung, or heart conditions. To mitigate risks, appropriate measures  must be introduced, and health and safety regulations followed.

According to  HSE's HSG 274 guidance, all water systems must undergo Legionella risk  assessments to ensure safety. Duty Holders, like employers or premise  controllers, are responsible for assessing Legionella risks, implementing safety  measures, and fulfilling legal obligations under the Health & Safety at Work  Act 1974 and COSHH Regulations 2002. The Corporate Manslaughter and Corporate  Homicide Act 2007 also holds companies accountable for negligence in duty of  care.  To assist, BPKS offers comprehensive  Legionella risk assessments, providing full reports and certificates within 10  days of testing. Additionally, we provide staff training for monthly tests and  record-keeping, ensuring compliance and safety for all involved.
