Compost Conundrums



We posted before about the potential of that nasty Legionella bacteria, lurking in compost, and it seems that research has been ongoing into this health concern.

A recent study of 22 different types of compost, carried out at Strathclyde University, in Glasgow, by a team of specialists, revealed that 14 of them carried a type of Legionella species known to cause Legionnaire's disease in humans. 

The study, "Legionella spp. in UK composts - a potential public health issue", concluded that

 "Legionella bacteria appears to be "common" in many compost brands sold in the UK" 

and suggests that a more extensive survey would be beneficial in order to clarify the extent of the problem.

Dr Beattie, one of the researchers who worked on the study, was quick to reassure compost consumers though, saying that although the bacteria is common the chances of infection are not. She does, however, think that UK compost manufacturers may benefit from following the lead of other countries, such as Australia and New Zealand, by putting hygiene warning labels on their products.

HSE Changing The ACOP (L8)

The HSE are conducting a consultation - it has been called to bring about changes to the ACOP (L8), to make a clearer, more definite set of guidelines.


We found the article on the FM World website; the report reads:


The legionella Consultative Document (CD258) sets out proposals from the HSE to publish an updated Approved Code of Practice (ACOP) on Legionnaire’s disease. 

The consultation provides an opportunity to comment on whether the draft ACOP text provides legal clarification and proportionate advice in low-risk scenarios. 

Accompanying guidance provides advice on achieving compliance, information of a general nature, including explanation of the requirements of the law, specific technical information or references to further sources of information. 

The revised ACOP gives practical advice on the legal requirements of the Health and Safety at Work etc Act 1974 and the Control of Substances Hazardous to Health Regulations 2002 (COSHH). It also applies to the risk from exposure to legionella bacteria and includes information of a general nature including explanation of the requirements of law. 

Interested parties can e-mail for more information: legionella.ACOPconsultation@hse.gsi.gov.uk 
Documents and comment forms can be downloaded here. 

The other two consultations concern the Control of Dangerous Substances and Explosive Atmospheres Regulations 2002 and the amended Control of Substances Hazardous to Health Regulations 2002.
Industry and interested parties have until 23 August to respond.

Reading Borough Council Carehome was source of Legionella

"A wash basin in a Reading Borough Council care home was the most likely source of Legionnaires’ disease that killed a 95-year-old man, an inquest heard.
Lewis Payne, of Knights Way, Emmer Green, was staying in The Willows care home, in Hexham Road, Whitley, when he contracted Legionnaires’ pneumonia.
Flaws in specific Legionnaires’ training for staff, record keeping and auditing at the home was also revealed at the inquest into his death yesterday.
Mr Payne became a resident in one of the home’s intermediate care flats from September 24, last year, for respite after fracturing his right leg.
Nearly three weeks into his stay he complained of feeling unwell.
When his condition did not improve an out of hours GP was called – he diagnosed pneumonia and a urine infection. Mr Payne was given the option of staying at The Willows with a stronger dose of antibiotics or being taken to Royal Berkshire Hospital (RBH) but he asked to stay.
On October 16 Mr Payne’s symptoms worsened and he was taken to the RBH where his urine tested positive for Legionnaires.
Despite receiving treatment he died on November 1. Following the discovery of Legionnaires an investigation was launched.
Bacteria was found in the wash basin of Mr Payne’s flat, one of the upstairs showers and an outside tap.
As Mr Payne had only had a basin wash while at the home the only likely way he came into contact with the bacteria was from the tap in his room, the inquest heard.
The care home’s water system was overseen by the council’s Property Services – they contracted water expert SMS Environmental to carry out health and safety risk assessments that would identify any potential hazards. That risk assessment was then kept with a log book in the care home office and should have identified what the care home was responsible for in terms of managing the water system and what SMS Environmental was responsible for.
However, The Willows unit manager Christine Mabbott admitted before Mr Payne’s death she was not aware of the council’s Legionnaires policy and had never had specific Legionnaires training.
Although she was aware there was a log book she had very little to do with it as she had delegated health and safety management to her deputy James Skelt, and the care home’s handy man Matthew Smith physically carried out the checks. In a statement read at the inquest Mr Smith said he had not checked the outside taps or de-scaled the shower heads as he was not aware he was meant to do this.
It was also revealed when Mr Smith went away on holiday nobody carried out the checks in his place which is why there were holes in the records.
Since Mr Payne’s death the council has introduced numerous measures to ensure the same mistakes were not repeated.
Mark Attree, engineering services manager for RBC, said: “Mr Payne’s death cannot be left to go in vain, we must learn from that.”
Since the incident the council has fitted every water outlet in the building with special bacteria filters.
However, the level of Legionnaires bacteria in the water is increasing, suggesting the source wasn’t localised, Mr Attree said.
Barrister Bryan McGuire, representing RBC, asked Mr Attree if the paperwork had been better would Mr Payne’s death have been avoided.
Mr Attree said: “I don’t think so because of what has happened since, something that is in that water system is creating the bacteria and we can’t isolate where the problem is.”
Recording a narrative verdict, Berkshire coroner Peter Bedford said: “Tests confirmed that the strand of Legionnaires found in the wash basin of Mr Payne’s room is the same type, that is not particularly common, found in his urine sample, supporting the view that on the balance of probability the tap was the source of the Legionnaires.
“While Legionnaires was the principal cause of death subsequent attempts to eradicate it has not proved completely successful.
“Investigations have identified flaws, in particular in regard to training, staff record-keeping and audit-taking but it is not possible to see from the evidence that these flaws contributed directly to Mr Payne’s death.”
Council confident measures are in place
In a statement issued after the inquest the council expressed its condolences to Mr Payne’s family and friends.
It added: “As an added precaution, the council has also carried out a review of all of its buildings stock across the borough and a detailed programme is in place for the council’s Legionella officer to visit sites on a monthly basis to ensure all relevant procedures are being followed.
“Reading Borough Council has taken the opportunity to re-emphasise to all relevant staff the importance of maintaining essential health and safety systems and to ensure that all records are kept up to date and are consistent and accurate. We are confident the measures put in place by the council will ensure this happens.”

Fernox F1 is suiable for use with Softened Water, says the HHIC


News has hit the grapevine than the inhibitor F1, made by Fernox, a market leader in water treatment chemicals, can be used with softened water.
In general, we shouldn't trust rumours, but the public release of the information has come strieght from the horses mouth -

we received a PDF press release, originally from fernox explaining the details a little bit. The technical bulletin states:

"In January 2013, the water treatment group of HHIC approved the following statement concerning the use of water softeners: 




Where a water softener is present in the dwelling ensure that a heating system primary circuit is filled with mains water via the general bypass valve as required within BS14173. Note: A water 
softener must comply with BS14173 (this states that there must be ‘a general bypass valve which 
enables the softening unit to be isolated from the mains, while maintaining water supply to the 
end user’. For installation requirements, refer to WRAS Information and guidance Note No 9-07-
01 “Information for the installation of ion exchange water softeners for systems supplying water 
for domestic purposes”. 
Refer to boiler manufacturer’s instructions for any additional advice on softened water."




Consequently any future central heating installation where a water softener is present should not be filled with softened water.

The DWTA support this advice, however there will still be some existing installations where the primary circuit has already been filled with softened water. For these installations, the following advice is still relevant.


When a central heating system is filled with base exchanged softened water, Fernox Protector F1 will adequately protect the heating system as long as it is correctly dosed and maintained t
throughout the life of the system. The correct dose rate of Fernox Protector F1 can be verified 
using either a Protector Test Kit or a Fernox System Health Check, both available from plumbing 
merchants.



This recommendation is identical to that given for natural waters and indicates that Fernox Protector F1 inhibits in all water conditions."

Basildon Blunder | Legionella strikes again


The awful and unnecessary disease legionella has one again made headway in the news. Basildon Hospital were recently prosecuted again by the HSE. They were prosecuted for breach under Section 3 of the Health & Safety at Work Act over failing to protect visitors and patients adequately from legionella.

Two people have unfortunately paid the price for the negligence to the water systems between 2007 and 2010. 

Alongside huge court costs of £100,000, the hospital spend 3 million (£) in measures to finally combat the bacteria.

Softened Water has been proven to NOT cause corrosion in aluminium heat exchangers


Report released in Woking, December 2012.

Since the 1980s, there has been disagreement within the professional water heating sector about the use of softened water in central heating systems with aluminium heat exchangers. The water softener manufacturers say that you can use softened water, while some of the chemical inhibitor manufacturers say you cannot.

To settle the argument, in March 2012 Harvey Water Softeners got together with other members of the UKWTA (United Kingdom Water Treatment Association) and commissioned BSI (British Standards Institute) to carry out a test and prove, once and for all, who was correct.

The results were announced by Harvey Bowden, the Chairman of Harvey Water Softeners, at the HHIC Annual Conference during the parliamentary reception at the House of Commons on Wednesday 28th November 2012.



The report states that, “Over the lifetime of a modern central heating system, filling with base-exchange softened hard mains water would appear to present no significantly greater risk of corrosion of system metals than filling with hard mains water”.

So one question remains : why there was confusion in the first place... was there another source of corrosion not accused? - further updates coming soon.

Harvey is a trusted brand of water softeners and has spent many years perfecting the brand - a trusted seller of Harvey equipment is Spectrum Softeners.
