Legionella contd...

In a legal context those who choose to operate spas have a duty of care to their to conduct their undertaking in such a way to ensure, so far as is reasonably practicable, that customers and others are not exposed to risk. An Environmental Health Officer or an HSE inspector could prosecute for putting staff or public at risk, however an improvement notice or prohibition notice following a poor microbiological test would be the more likely approach. Consistent poor microbiological readings in a spa would justify more severe enforcement action.

A spa can be run safely but requires a degree of effort and a substantial amount of training and expertise. A well-run spa is a benefit to health and physical well being. With inadequate effort they will become a liability. Organisations who cannot constantly manage a spa and maintain them at the correct standards should consider not operating them at all.

Management of legionella in general water systems

• Legionella bacteria are found in natural water sources and water systems, and grow in temperatures of between 20°C - 45°C and are destroyed above 60°C.
• The bacteria require nutrients to grow and survive. Sludge, sediment and scale provide this.
• Legionella is spread by inhalation of water droplets containing legionella bacteria.
• Symptoms of the Legionnaires’ Disease are flu-like, with high fever and headache. The disease can be fatal and generally affect vulnerable people such as the elderly, children or the infirm.
• There is no risk of infection from one person to another.
Persons in charge of premises must identify all plant equipment that could encourage the growth of legionella.< Previous Next >
