Closed Recirculating Water Systems: Monitoring the health of your system by sampling

Welcome back to our series on closed recirculating water systems. Last time out we looked at the maintenance required to keep closed systems healthy and working efficiently which included the addition of speciality chemicals such as corrosion and scale inhibitors. We finished on the point that where using these chemicals it is essential to maintain a specific ‘reserve’ or concentration of these products within the water system and to monitor this requires samples to be taken, but how many, where from and at what frequency? When considering the testing can on-site analysis be sufficient or do the samples require analysis in a laboratory setting?

Closed Recirculating Water Systems: A Deep Dive into Closed Water System Management and Treatment Strategies

Greetings everyone, welcome back to our ongoing series where we explore the best practices for managing closed recirculating water systems. In our previous discussion, we delved into the potential issues that can arise when proper care is not taken with closed systems. Today, we will be taking a closer look at the various treatment options available for maintaining and even improving the health of these systems.

Legionella Risk Assessment: When And How Often Should My Risk Assessment Be Reviewed?

How Often Should My Legionella Risk Assessment Be Reviewed?

Continuing on our Legionella Risk Assessment series. Last time we took a ‘deep dive’ into the competence which should be expected of a risk assessor as well as proportionality in assessing large portfolios of similar building stock. In this article we will be taking a look at the guidance around completing Legionella risk assessment reviews. In our experience it’s not uncommon for ‘end users’ to ask the question- When should I review an existing Legionella risk assessment? Its not uncommon to hear very different opinions on this matter but fortunately there are a number of excellent information sources which can be consulted on when a risk assessment should be reviewed.

Legionella Risk Assessments: Competence Of A Legionella Risk Assessor

Competence Of A Legionella Risk Assessor And Proportionality

Last time we looked at agreeing the scope of the assessment and the independence of the risk assessor, next we will be reviewing the competence of the assessor which is a topic that is becoming more widely discussed. So, let’s start with a simple question – What experience and specialist knowledge should a Legionella risk assessor demonstrate? Well both BS8580-1:2019 and the LCA’s Risk Assessment standard for service delivery outline the expectations of knowledge and understanding required by risk assessors, these include but are not limited to:-

Legionella Risk Assessment: Agreeing The Scope & Demonstrating Independence

Why an understanding of the BS8580:2019 Standard is vital to ensuring a compliant Legionella Risk

A compliant Legionella control scheme must be based on a compliant risk assessment, but what does that really mean? What do you need to do to comply with the British standard?

Many Legionella service providers claim that their risk assessments are conducted and produced in line with the British standard for Legionella risk assessments, BS8580-1: 2019, but what does that really mean? What do you need to do to comply with the British standard?

Legionella: The Definitive Guide To Post Clean and Disinfection Sampling

Welcome back! In the final edition of our three-part series clean and disinfections for Legionella management, ‘what does a ‘good’ clean and disinfection look like’ we will take a detailed look at ‘post’ disinfection verification sampling and answer the question what is a ‘compliant’ clean and disinfection.

 

 

In this article we will:

 

 

  • Discuss the importance of post-disinfection verification sampling.
  • Explain the different types of sampling methods that can be used.
  • Discuss when and where to take post clean and disinfection sampling.
