legionella risk


JMCD Plumbing and Heating Engineers Halifax carry out legionella risk assessments on both domestic and commercial hot and cold water systems. Legionnaires' disease is a potentially fatal form of pneumonia caused by the inhalation of small droplets of contaminated water containing Legionella. All man-made hot and cold water systems are likely to provide an environment where Legionella can grow. Where conditions are favourable (ie suitable growth temperature range; water droplets (aerosols) produced and dispersed; water stored and/or recirculated; some 'food' for the organism to grow such as rust, sludge, scale, biofilm etc) then the bacteria may multiply thus increasing the risk of exposure.  It is a simple fact that the organism will colonise both large and small systems so both require risks to be managed effectively.

about Legionella


Legionella is the bacteria that can contaminate your water supply and expose yourself or your tenants to legionnaire’s disease. A Legionella bacterium is naturally present within water supplies in all properties. This bacterium enters domestic water system via mains supply. Due to the conditions within domestic properties the bacterium increases in growth. Many factors which increase the growth are the temperature of the water, nutrient sources (Scale, sediment, corrosion, algae, micro-organisms and materials) and the stagnation of water.

Contaminated water is aerosolized by showers and taps, meaning the inhalation of tiny droplets is drawn deep into the lungs which can cause a severe form of Pneumonia.
