Legionnaires’ disease is a potentially fatal form of pneumonia. It is caused by the legionella bacteria which can develop in any system where water is stored at temperatures favourable to its growth; water tanks, calorifiers, hot and cold-water systems, pools and spas.
On caravan and holiday parks, the statutory duty holder for the premises is responsible for making sure the site is risk assessed, and ensuring that regular checks are carried out to prevent the conditions occurring that might allow the bacteria to grow. Failing to comply can result in serious health implications and even death in some cases. Businesses also risk severe fines or, in the worst cases, prosecution for involuntary manslaughter.
