PTSG has recently created a fifth business division: PTSG Water Treatment Ltd. This has enabled the Group to work with customers in even more sectors, bringing compliance and safety through a number of key services.

Legionella bacteria is commonly found in water. The bacteria multiply where temperatures are between 20°C and 45°C and nutrients are available. The bacteria are dormant below 20°C and do not survive above 60°C.

Legionnaire’s disease is a potentially fatal type of pneumonia, contracted by inhaling airborne water droplets containing viable Legionella bacteria. Such droplets can be created, for example, by hot and cold water outlets, atomisers, wet air conditioning plants and whirlpool or hydrotherapy baths.

Anyone can develop Legionnaire’s disease, but the elderly, smokers, alcoholics and those with cancer, diabetes or chronic respiratory or kidney disease are more at risk.

At PTSG, Our Water Treatment specialists have a wealth of experience in conducting Legionella risk assessments across all industry sectors. Building owners are responsible for their work premises under the Health and Safety Act 1974.

They must carry out a risk assessment of the property or premises that assesses the risk of exposure to Legionella. We can make them aware of what Legionella is, what systems are hazardous and which are low-risk.

The HSE’s Approved Code of Practice (ACoP) L8 is a guideline document for the prevention and control of legionellosis in water systems and has a special legal status by which the employer can be prosecuted, fined or even imprisoned, if it is proved that you did not follow the relevant provisions of the Code.

Our risk assessment follows the guidance set out in BSEN 8580:2010 which gives recommendations on the assessment of the risk of legionellosis presented by artificial water systems. The assessment will conclude on the condition of plant and advise you of any remediation necessary in order to reduce the risk from Legionella bacteria.
