Legionellosis or Legionnaire’s Disease in Spa and wellness centre

Are you the owner or manager of a spa, hot tub or pool, or do you provide showers and air conditioning for your clients? Make sure you are fully aware of the dangers of legionnaire’s disease and the risks to your clients, and understand what your legal obligations are.

What exactly is Legionnaire’s Disease?

Legionnaire’s disease is a serious disease caused by a tiny aquatic organism which thrives in warm, damp environments. It can be inhaled in fine droplets, leading to pneumonia and a high fever. As the disease takes up to 10 days to develop many other people may be infected before it is realised that anything is amiss. Air conditioning systems, humidifiers, nebulisers, ornamental fountains and many other types of equipment containing water may also be sources of legionnaire’s disease.

How can it be prevented?

Because of its long incubation period an outbreak is easier to prevent than to control and there are strict regulations in place to safeguard public health. The essential feature is a controlled system of regular testing and keeping water systems clean. Although legionella bacteria can be found in many sources, including fresh water, it becomes dangerous when slime is allowed to develop and when the temperature reaches 35-45 degrees centigrade.

What are my legal obligations?

According to www.hse.gov.uk, under general Health and Safety law you are obliged to maintain your water systems in good condition and assess the risk of a problem developing. This means drawing up a risk assessment, identifying potential sources of legionnaire’s disease and preparing a course of action to monitor that risk. You must keep accurate records and be able to prove you are taking your responsibilities seriously.

The Notification of Cooling Towers and Evaporative Condensers Regulations state that if you have a cooling tower or evaporative condenser on site you must notify the local authority in writing. Contact your local Environmental Health department.

 

What should I do on a daily basis?

If you employ five people or more, you must have a written risk assessment and keep careful records of your monitoring of the water system. Make sure you have a responsible person do this and that all your staff know the correct way to use equipment.

Keep the system and the water clean, and avoid a situation where an outbreak could develop. Keep the water too hot for the bacteria to survive or add an antibacterial solution to prevent growth.

Consider employing a firm of consultants to check your supply.
