remote water TEMPERATURE monitoring
Legionnaire’s disease is not contagious, although it can be fatal by causing a form of pneumonia. It is formed from an infection by Legionella bacteria found in water and soil. High risk systems can include cooling towers, steamers, showers, baths, air conditioning units and much more.
Reducing the risk of Legionnaire’s disease and Legionella with water systems can best be achieved using temperature monitoring and control. As Legionella thrives between 20°C – 45°C best practice should be to ensure the following temperatures are maintained at all times. Hot water should be stored above 60°C, Cold water should be kept below 20°C.
Water Health & Safety
Our IoT water temperature monitor is being successfully incorporated into healthy water system management by our partners in the FM and water safety/hygiene industry across numerous sectors including nursing and care homes, hospitals, offices, schools, universities, social housing and health and community centres. Providing 24/7 remote water temperature and flow monitoring of outflows and storage vessels in real time, our IoT device is designed with a fit and forget style approach, with alerts being raised on high-risk temperatures that could encourage growth of the legionella bacteria, enabling quick action to be taken.
WHAT IS LEGIONNAIRES DISEASE AND HOW TO PREVENT IT
Did you know that incorrect water temperature is a key risk factor for legionella growth. Legionella growth can of course lead to Legionnaires Disease. If you are an employer or person in control of a premises then you must organise a risk assessment from exposure to legionella. Here are some key facts about Legionnaires Disease, what to expect and how to prevent it…
THE APPROVED CODE OF PRACTICE (ACOP) LEGIONNAIRES’ DISEASE
Issued by the Government’s Health and Safety Executive (HSE) this code significantly extends the scope of its guidance on control of legionella bacteria in water. The code applies to all hot and cold water systems in the workplace regardless of their capacity, i.e. the lower limit of 300 litres previously used to exclude domestic systems, no longer applies. Whilst domestic systems may represent a risk, the code only applies to a risk arising from a work activity. This means that all employers, who manage premises with hot/cold water systems and/or wet cooling systems, have a legal responsibility to identify any risk of contamination and to prevent or control it. These records have to be kept for a minimum of five years.
WHAT ARE THE SYMPTOMS OF LEGIONNAIRES’ DISEASE?
Initial symptoms usually include flu-like symptoms, such as: mild headaches, muscle pain, high temperature (fever) usually 38C or above, chills, tiredness and changes to your mental state such as confusion. Once bacteria begin to infect your lungs, you may also experience symptoms of pneumonia, such as: a persistent cough – which is usually dry at first, but as the infection develops then you may start coughing up phlegm or, rarely, blood, shortness of breath and chest pains. It normally takes six to seven days between getting the infection and the start of symptoms, known as the incubation period thought it can be up to 19 days. Legionnaires’ disease has similar symptoms to other illnesses therefore your recent travel history is very important when attempting to diagnose the disease. If an infection is suspected, a urine test can be used to check for Legionnaires’ disease.
HOW IS LEGIONNAIRES’ DISEASE IT CAUGHT?
Legionnaires’ disease is caught by inhaling small droplets of water suspended in the air which contain the legionella bacterium, e.g. spray from showers and taps. However the disease isn’t contagious and cannot be spread directly from person to person.
WHAT ARE THE SOURCES OF LEGIONELLA BACTERIUM?
The legionella bacterium is found mainly in stagnant water, e.g. ponds and rivers or buildings containing cooling tower, evaporation condensers, air conditioning and industrial cooling systems, humidifiers, spa baths and hot and cold water systems.
WHAT AREAS ARE MOST VULNERABLE?
A wide range of workplaces, but particularly residential accommodation managed privately or by organisations, e.g. local authorities, universities, hospitals, nursing and care homes, housing associations, charities, hostels, private landlords, managing agents, hoteliers and holiday accommodation providers, including guest houses and camping/caravan site owners.
