What Does Legionella Compliance Mean?

June 4, 2020, by Tower Water

water treatment solutionsCooling towers and other spaces in facilities where water is stored need to be routinely cleaned, among other reasons, in order to prevent the accumulation of sludge, sediment, scale, and algae. This type of contamination can lead to the development of diseases if left unchecked. One such disease is Legionnaires’ disease, a form of pneumonia caused by Legionella bacteria. The Center for Disease Control (CDC) has noted that Legionella bacteria can also cause Pontiac fever (a flu-like illness) and occasionally, some more serious diseases such as legionellosis (extrapulmonary infections).

Given this, let’s take a close look at Legionella compliance and its significance today. Tower Water in New York and New York City is always committed to providing this type of compliance.

What Is Legionella?

Legionella is a type of bacteria that naturally forms in freshwater environments such as streams and lakes and that can spread to artificial building water (potable and nonpotable) systems. Scientific experts named it after an outbreak that occurred in Philadelphia in 1976, during which several residents of the city became sick with pneumonia after attending an American Legion convention.

How Common is Legionnaires’ Disease?

The CDC stated that in 2018, health departments reported almost 10,000 cases of Legionnaires’ disease in the United States. It also estimates that 10% of people infected with this illness can die. Legionella.org also recently estimated that up to 113,000 people in the U.S. have become infected with Legionella bacteria. One can become infected with Legionnaires’ disease after breathing in small droplets of water in the air. Common symptoms of this illness include chills, high fever, cough, headaches, and diarrhea. Specialized laboratory tests are often required to diagnose Legionnaires’ disease. Direct fluorescent antibody (DFA) blood tests, for example, involve the use of a microscope.

The Basics Of Legionella Compliance

Legionella compliance testIn the United Kingdom, for instance, an organization’s responsibilities regarding adherence to water management laws and regulations are recorded in the Health and Safety at Work etc Act of 1974. They are also documented in the 2002 Control of Substances Hazardous to Health Regulations. The UK’s Health and Safety Executive (HSE) government agency oversees many of these regulations.

In the U.S. many state and city municipal health departments (including New York State’s and City’s) have specific requirements and even laws governing the control and testing of this dangerous bacteria.

Legionella Risk Assessments

This type of risk evaluation will often consist of:

  • An easy-to-understand diagram of a water system;
  • A report detailing risk factors like abnormally high or low water temperatures, stagnant water conditions and the existence of deposits that enable Legionella growth, or vulnerable building users;
  • An assessment of existing control measures and an outline of all methods needed to manage and track risk levels.

Legionella Control Measures

Adequate control initiatives allow organizations can take to manage and monitor the development of Legionella bacteria include:

  • Tank and water system chlorination, and testing
  • Pipework insulation and lagging
  • Maintenance of thermostatic mixing valves (TMV), which blend hot and cold water
  • Removing dead legs (lengths of pipe through which water can’t move) from a system
  • Training staff members to compliantly conduct checks.
  • Proximity to misting devices to fresh air plenums

Routine Inspections

mitigate the risk of Legionella and other harmful bacteriaAs in other industries where cleaning and maintenance are essential, regular inspections of water systems can help mitigate the risk of Legionella and other harmful bacteria appearing in a system. Routine appointments for such walkthroughs, which can make a major difference in this respect of noticing a concern before it becomes a problem.

Accurate & Concise Record-keeping

Organizations are generally required by law to maintain records that prove their compliance with regulations, and the water treatment industry is now no different. This means documenting all inspections, risk assessments and control measures in order to avoid fines and other penalties. You are required to create a checklist to ensure you are constantly complying with all laws.
