REVIEW DATE

In accordance with ACOP L8 Paragraph 38, ‘The Risk Assessment should be reviewed regularly (at least every two years)’. The maximum review date for this Risk Assessment is therefore: 23rd March 2016

1.4 

WHAT IS LEGIONNAIRES’ DISEASE? Legionnaires’ disease was first identified following a large outbreak of pneumonia among people who attended an American Legion Convention in Philadelphia in 1976. A previously unrecognised bacterium was isolated from lung tissue samples that were subsequently named Legionella pneumophila. It is normally contracted by inhaling Legionella bacteria, either in tiny droplets of water (aerosols), or in droplet nuclei (the particles left after the water has evaporated) contaminated with Legionella, deep into the lungs. There is evidence that the disease may also be contracted by inhaling Legionella bacteria following ingestion of contaminated water by susceptible individuals. Person-to-person spread of the disease has not been documented. Initial symptoms of Legionnaires’ disease include high fever, chills, headache and muscle pain. Patients may develop a dry cough and most suffer difficulty with breathing. About one third of patients infected also develop diarrhoea or vomiting and about half become confused or delirious. Legionnaires’ disease can be treated effectively with appropriate antibiotics. The incubation period is between 2-10 days (usually 3-6 days). Not everyone exposed will develop symptoms of the disease and those that do not develop the ‘full blown’ disease may only present with a mild flu-like infection. Infection with Legionella bacteria can be fatal in approximately 12% of reported cases. This rate can be higher in a more susceptible population; for example, immunosuppressed patients or those with other underlying disease. Certain groups of people are known to be at higher risk of contracting Legionnaires’ disease; for example, men appear more susceptible than women, as do those over 45 years of age, smokers, alcoholics, diabetics and those with cancer or chronic respiratory or kidney disease. The disease is usually diagnosed by a combination of tests. The organism may be cultured from the patient’s sputum, bronchial washings or lung tissue. Alternatively, tests are used to measure the presence of antibodies in the blood and, increasingly, tests are available to measure specific antigens in the patient’s urine.

Introduction_Continued

WHAT IS LEGIONNAIRES’ DISEASE? - Continued L. pneumophila is also responsible for a short feverish form of the illness without pneumonia, known as Pontiac fever. Its incubation period is typically between 2-3 days. Another species of Legionella, L. micdadei, is responsible for a similar form of the illness without pneumonia called Lochgoilhead fever after an outbreak in Lochgoilhead, Scotland. The incubation period can be up to 9 days. A high percentage of those exposed to this agent tend to be affected. However, there have been no recorded deaths associated with either Pontiac or Lochgoilhead fevers. To date, approximately 40 species of the Legionella bacterium have been identified. L. pneumophila causes about 90% of cases. Sixteen different serogroups of L. pneumophila have been described; however, L. pneumophila serogroup 1 is most commonly associated with cases of Legionnaires’ disease in the UK. L. pneumophila serogroup 1 can be further sub-divided to distinguish between strains most commonly associated with Legionnaires’ disease. Additionally, ‘genetic fingerprinting’ methods such as Restriction Fragment Length Polymorphism (RFLP) and Amplified Fragment Length Polymorphism (AFLP) can be valuable tools in the investigation of outbreaks. Such methods of typing can sometimes provide a means of linking the organisms isolated from patients to the sources of cases of outbreaks.

1.5

REQUIREMENTS OF THE APPROVED CODE OF PRACTICE (ACOP L8)

The Approved Code of Practice applies to the control of Legionella bacteria in any undertaking involving a work activity and to premises controlled in connection with a trade, business or other undertaking where water is used or stored and where there is a means of creating and transmitting water droplets which may be inhaled, thereby causing a reasonably foreseeable risk of exposure to Legionella bacteria. A reasonably foreseeable risk of exposure to Legionella bacteria exists in:    

Water systems incorporating a cooling tower, Water systems incorporating an evaporative condenser, Hot and cold water systems, Other plant and systems containing water which is likely to exceed 20°C and which may release a spray or aerosol (i.e. a cloud of droplets and/or droplet nuclei) during operation or when being maintained.

A suitable and sufficient assessment is required to identify and assess the risk of exposure to Legionella bacteria from work activities and water systems on the premises and any necessary precautionary measures. The assessment is carried out by or on behalf of:  

The employer, where the risk from their undertaking is to their employees or to others, A self-employed person, where there is a risk from their undertaking to themselves or to others, The person who is in control of premises or systems in connection with work where the risk is present from systems in the building (e.g. where a building is let to tenants but the landlord retains responsibility for its maintenance).

Introduction_Continued

REQUIREMENTS OF THE APPROVED CODE OF PRACTICE (ACOP L8) -Continued

A number of factors are required to create a risk of acquiring Legionellosis, such as:  

 

1.6

The presence of Legionella bacteria, Conditions suitable for multiplication of the organisms, e.g. suitable temperature (20°C45°C) and a source of nutrients, e.g. sludge, scale, rust, algae and other organic matter, A means of creating and disseminating breathable droplets, e.g. the aerosol generated by a cooling tower or shower, The presence (and numbers) of people who may be exposed, especially in premises where occupants are particularly vulnerable, e.g. healthcare.

OBJECTIVES

The purpose of this survey is to assess the risk to occupants, tenants, employees and visitors at St Johns Primary School, Hamilton in respect of Legionellosis resulting from the operation of domestic water systems. 1.7

DISCLAIMER

The risk assessment inspections within this document were achieved on a non – intrusive basis. No warranty as to the completeness of the information is given. There must be an ongoing programme of due diligence, both observations, record keeping and remedial actions. Regular maintenance regimes are critical to the operation and safety of the systems included in the risk assessment. ECG Facilities Services disclaim all liability and responsibility for any direct or indirect loss or damage that may have occurred through reliance on any information contained or omitted from this document, and no person should act solely on the basis of the information contained in the document without taking appropriate professional advice about obligations in specific circumstances.

EXECUTIVE SUMMARY

On 24th March 2014 a water hygiene survey and Legionella risk assessment was carried out at St Johns Primary School which is owned and operated by South Lanarkshire Council. St Johns Primary is a mainstream Primary School consisting of multiple occupants of varying ages and sex who come under the susceptible or at risk category of contracting Legionnaires disease. After completion of the survey the school was designated as being at ‘MEDIUM’ risk. The following risk systems are present      

Showerheads and hoses which can form an aerosol conducive to Legionella transmission. Stored cold water storage vessels mainly cold water storage tank Stored Hot water vessel mainly the calorifier located in the plant room. Flexible hosing of the non-braided non-WRAS approved variety. Thermostatic mixing valves which discharge water below the prescribed minimum approved temperature of 50 degrees. Various deadlegs located throughout the premises

Consideration should be given to the following.    

Upgrading of the flexible hoses to WRAS approved non-braided type. Implementation of a servicing and calibration regime to cover the thermostatic mixing valves. Deadleg removal survey Implementation of a more robust weekly flushing regime

SITE OVERVIEW

St Johns Primary School, Hamilton is a brick, concrete and steel built building erected in 2008. It is a South Lanarkshire Council primary school consisting of classrooms, toilets, cleaner’s rooms, medical room, therapy room, staff room and kitchens. There are two cold water storage tanks that supply all domestic cold water to all areas via a twin pump set. They also supply the cold feed to the two water heaters in the main plant room – See asset register. There are two ACV Heatmaster water heaters located in the main plant room that supply all domestic hot water through an adjustable blending valve to all areas – See asset register. Temperatures were found to be outwith the legionella proliferation range.

RISK-RATING MATRIX

The purpose of producing a risk-rating matrix (although not a specific requirement of a risk assessment) is to assist the client in assumption of the risk and subsequently our observations on the water services associated within the building are rated on the following basis (weighting factor) High Risk

-

30 points

Medium Risk

-

20 points

Low Risk

-

10 points

The total amount of high, medium and low risk points will be calculated to give a final total and subsequently divided by the amount observations to give an overall percentage (%) risk

TOTAL (HIGH, MEDIUM & LOW RISK SCORES) x 100 TOTAL AMOUNT OF OBSERVATIONS x 30 = PERCENTAGE (%) RISK

7.00 Action In The Event Of An Outbreak

1

Legionnairesâ&#x20AC;&#x2122; disease is not notifiable under Public Health Legislation in England and Wales but, in Scotland, Legionellosis (i.e. all diseases caused by Legionella) is notifiable under the Public Health (Notification of Infectious Disease (Scotland)) Regulations 1988.

2

An outbreak is defined by the Public Health Laboratory Service (PHLS) as two or more confirmed cases of Legionellosis occurring in the same locality within a six-month period. Location is defined in terms of the geographical proximity of the cases and requires a degree of judgement. It is the responsibility of the Proper Officer for the declaration of an outbreak. The Proper Officer is appointed by the local authority under Public Health Legislation and is usually a Consultant in Communicable Disease Control (CCDC). In Scotland, it is the Consultant in Public Health Medicine (CPHM) employed by the Health Board and acting as Designated Medical Officer for the local authority.

3

Local authorities will have established incident plans to investigate major outbreaks of infectious disease including Legionellosis. These are activated by the Proper Officer who invokes an Outbreak Committee, whose primary purpose is to protect public health and prevent further infection. This will normally be set up to manage the incident and will involve representatives of all the agencies involved. HSE or the local authority EHO may be involved in the investigation of outbreaks, their aim being to pursue compliance with health and safety legislation.

4

The local authority, CCDC or EHO acting on their behalf (often with the relevant officer from the enforcing authorities â&#x20AC;&#x201C; either HSE or the local authority) may make a site visit.

5

As part of the outbreak investigation and control, the following requests and recommendations may be made by the enforcing authority: (a) To shut down any processes which are capable of generating and disseminating airborne water droplets and keep them shut down until sampling procedures and any remedial cleaning or other work has been done. Final clearance to restart the system may be required. (b) To take water samples (see paragraphs 124-131, Part 2) from the system before any emergency disinfection being undertaken. This will help the investigation of the cause of the illness. The investigating officers from the local authority/ies may take samples or require them to be taken. (c) To provide staff health records to discern whether there are any further undiagnosed cases of illness, and to help prepare case histories of the people affected. (d) To co-operate fully in an investigation of any plant that may be suspected of being involved in the cause of the outbreak. This may involve, for example: (i) Tracing of all pipework runs (ii) Detailed scrutiny of all operational records (iii) Statements from plant operatives and managers (iv) Statements from water treatment contractors or consultants. 6

Any infringements of relevant legislation may be subject to a formal investigation by the appropriate enforcing authority.
