The Hidden Danger Of Asbestos In UK Schools: 'I Don't Think They Realise How Much Risk It Poses To Students'

Mesothelioma develops rapidly and has no cure. Symptoms include chronic productive coughing, breathlessness, chest pain and fatigue. While treatment innovations are progressing, the disease is not curable and about 60% of patients die within a year of receiving a diagnosis.

The particular threat posed to teachers and school workers was highlighted in a recent analysis which suggested that the risk to women in their late-40s to mid-60s who have worked in schools is statistically significant. This builds on earlier data that had identified a potential elevated risk for female teachers and education professionals.

Hagedorn, who died in 2014, told the tes she had been shocked by her diagnosis, which is more usually associated with men who have worked in heavy industries. Having been forced to retire due to ill-health, she said she was angry at being viewed as“some sort of collateral damage or natural wastage in the education game”.

But it is not just teachers and school workers who are of concern – many children may have been exposed while at school. However, since mesothelioma is regarded as an industrial disease and being a child is not an occupation, the Office for National Statistics (ONS) keeps no data on deaths from mesothelioma due to exposure to asbestos as a school pupil.

Following her diagnosis, Hagedorn warned in the evening standard in 2009:

In March 2011, the UK's supreme court ruled that Dianne Willmore had been exposed to asbestos while she was a pupil at Bowring Comprehensive in Liverpool in the 1970s. As a result, she developed what the court called the“hideous disease” of mesothelioma.

Willmore had died in 2009, aged 49 – just hours after the court of appeal first decided she was entitled to compensation. One of the UK's leading experts on asbestos-related cancers, julian peto , later estimated to a parliamentary select committee that between 200 and 300 former pupils would die each year as a result of their exposure to asbestos while at school in the 1960s and '70s.

Today, deaths of former pupils from mesothelioma due to asbestos exposure are still not officially recognised. Instead, they remain hidden among the UK's unusually high“background rate” of the disease, not included as a specific ONS category. Yet children are particularly vulnerable to asbestos – a point made starkly ten years ago in a report for the Department for Education (DfE):

Mesothelioma risk from asbestos is unlike lung cancer risk from smoking. If a smoker gives up, the risk of lung cancer declines over time. By contrast, the risk of mesothelioma from an exposure to asbestos accumulates over time . A five-year-old child who is exposed to asbestos has been estimated to be five times more likely to develop mesothelioma during their lifetime than an adult who is first exposed at the age of 30.

In the absence of hard data on deaths from mesothelioma due to exposure as a pupil at school, a document from the US Environmental Protection Agency (EPA) is widely cited . Using US data to develop a model of the risk presented to both workers and pupils in schools, the report concluded that around 90% of premature deaths due to asbestos exposure at school occur in people who were exposed as children.

Putting the Peto and EPA estimates together, the Joint Union Asbestos Committee subsequently reported that over the period 1980-2017, the number of UK mesothelioma deaths as a result of exposure to asbestos as school pupils was between 3,890 and 9,000 .

In 2021-22, we conducted our own review of media and legal coverage of 84 people who had developed mesothelioma after being exposed to asbestos while working in UK schools. These included heart-rending interviews with patients and relatives who, despite their own suffering, were keen to highlight wider concerns about the threat that asbestos in schools might pose to children.

For example, Mick Adkins, an electrician contracted to work in Birmingham schools and who died of mesothelioma, told the sunday mercury in 2007:

And Freddie Davis – husband of Pearl, a former primary school teacher in Gillingham and Chatham who died of mesothelioma – reflected after her death :

The presence and problem of asbestos in schools has been known about for many years. A 2019 DfE survey suggested that around 81% of primary and secondary state schools in England still have asbestos“present on their estate” – despite the use of asbestos in any form having been banned in the UK since 1999.

Commercial exploitation of asbestos in the UK began in the 1870s . Its resistance to high temperatures and fire made it valuable in steam-powered industries. The same properties later made it useful as a fire retardant and heat insulator in buildings.

Between 1920 and 1970, the UK was the largest importer of asbestos in europe . This period includes the massive post-war rebuilding programme which made widespread use of prefabrication , or system building, to rapidly erect buildings including many homes and schools, often with asbestos incorporated.

The UK's relatively cold climate also meant that better insulating – but more dangerous – types of asbestos were used. And its links with former colonies, particularly Australia and South Africa, allowed the UK to import asbestos at cheaper rates than the rest of europe .

As a result of this high usage, the UK now has one of the world's highest rates of mesothelioma . In 2020, there were 2,544 mesothelioma deaths registered. The annual UK total has now been increasing year-on-year for more than 50 years, such that the 2010s saw more than eight times as many deaths from mesothelioma as the 1970s.

The very first UK death from lung fibrosis caused by asbestos was reported back in 1899. The first UK government regulations aimed at controlling exposure to asbestos were introduced in 1931, and carcinoma due to asbestos exposure was first described in 1935 . By 1960, it was known that asbestos exposure at low levels could cause mesothelioma.

Yet three years earlier, the Consortium of Local Authorities Special Programme (clasp ) had been introduced in England with the aim of developing prefabricated school buildings using a modular design around a steel framework.

The open and light nature of these structures made them vulnerable to fire – and so, asbestos was extensively used within them for its retardant properties. It was embedded in ceiling panels, wall boards, pipe lagging, and to cover any structural gaps. The asbestos used in Clasp buildings included large amounts of the even more dangerous amosite type, also known as“brown” asbestos.

Thousands of Clasp buildings – mainly schools – were constructed, particularly in coal mining areas such as Nottinghamshire and Derbyshire that were likely to be affected by subsidence (the modular design allowed for easier replacement and repair). An estimate in 2016 suggested that around 3,000 of these buildings were still in use.

While further schemes similar to Clasp continued into the 1970s, system building in general fell out of favour. However, up to the UK's outright ban on asbestos in 1999, it was still being used in specific building features such as radiator panels. Today, system-built schools remain of particular concern to health researchers as they age and deteriorate.

Under the present control of asbestos regulations 2012 , those responsible for the maintenance and repair of non-domestic premises, such as schools, are required to follow a policy of“in-situ management”. This is based on the idea that asbestos presents little risk provided it is in good condition and not disturbed.

The estimated four in every five UK state schools that have asbestos on their estate are required to have an asbestos management plan , designed to ensure its condition is regularly monitored. Should its condition deteriorate, then the asbestos would be removed alongside compulsory monitoring of air quality. Between September 2022 and March 2023, the Health and Safety Executive carried out 400 school inspections to make sure asbestos in schools was being correctly managed.

But our research shows that such management plans can, in some cases, become little more than box-ticking exercises, not necessarily performed well. As Carol Anthony, whose husband Alan, a teacher, died of mesothelioma in 2011, later reflected :

And even well-kept management plans run into the problem that schools typically experience high levels of damage and deterioration. Asbestos can be found in panelling under radiators, within electric storage heaters with blowers, and in music room walls and ceilings, for example. All may be vulnerable to curious or mischievous schoolchildren.

A teacher of 27 years in north Lincolnshire, Elizabeth Belt, who died of mesothelioma in 2015, gave a statement before her death which outlined many occasions when she believed she had been exposed to asbestos. For example:

Similarly, Joan Henry, a drama teacher in Havering, east London, who died of mesothelioma in 2009, had noted :

The“mischievous” nature of children was first established to be of legal significance in 1893 , when a case concerning the responsibilities of a schoolmaster acknowledged that:

The legal importance of this is that those responsible for health and safety in schools, such as education authorities, are required to allow for how children behave when devising management plans. But there is little evidence that they do this in the asbestos plans kept by schools.

The Willmore supreme court hearing , for example, cited several acts of mischief and bullying that may have exposed her to asbestos dust:

And this point is supported by a collated report of 291 failures of asbestos management in schools that resulted in the release of asbestos fibres between September 2000 and March 2014. This report was written by Michael Lees, a founder member of the asbestos in schools group , whose wife Gina was a nursery school teacher who died at the age of 51 following exposure to asbestos at work. In a 30-year teaching career, she had worked at 25 schools, most of which contained asbestos.

There are also concerns about the level of knowledge among those who work in schools containing asbestos. The Health and Safety Executive's guidelines require only fairly minimal interventions – for example, that the employee responsible for the asbestos plan:

It seems unlikely that this takes adequate heed of the“mischievous” nature of children. In addition, there seems to be little requirement for education or training regarding asbestos.

Elizabeth Bradford worked as an infant school teacher for many years, including in a building prefabricated from asbestos-containing materials on which she pinned children's work. In a video recorded in 2011, she said:

According to the international agency for Research on Cancer and the world health organization , all types of asbestos cause cancer in humans, but the risk increases with type. The ratio of risk for white (chrysotile), brown (amosite) and blue (crocidolite) asbestos has been estimated at 1:100:500. The danger is related to each material's“friability”, as well as to the toxicity of the fibres that are released and inhaled.

malignant mesothelioma is a rare and aggressive cancer with a high symptom burden. It most commonly affects the lungs, although it can also affect the abdomen and testes. It causes a range of debilitating symptoms including breathlessness, pain, fatigue and cough – which can often emerge quite suddenly.

According to the ons , 463 former or current teaching and educational professionals (male and female) died from mesothelioma between 2001 and 2020. However, this is likely to be a significant underestimate – in part because the deaths of people over the age of 75 are not recorded by former occupation. And of those cases that are recorded, only the final occupation is mentioned, so this total also doesn't include people who moved on from teaching to another career.

Bernard Dawson, a father of five and grandfather of seven, taught maths and science for more than 50 years in Greater Manchester and Lancashire schools. Soon after retirement, he was diagnosed with mesothelioma but died aged 81, so would not have been included in the ONS statistic above.

When teaching, Dawson regularly used asbestos mats for Bunsen burners and recalled seeing asbestos dust in store cupboards. After his death in 2016, his widow Maureen told the manchester evening news :

One problem for those who have not worked in the recognised high-risk industries, such as construction, is that the“index of suspicion” among health professionals may be low. In other words, symptoms that would trigger immediate suspicion in a former carpenter may not do so in a former nurse or teacher. There is also evidence that women in general may be viewed with a lower index of suspicion regarding possible symptoms of mesothelioma.

While no statistical research has yet investigated this, qualitative studies of school and hospital workers (including ours ), as well as of women , have identified numerous examples. As retired school teacher rosie peters said in an interview less than a year before her death due to mesothelioma:

People outside high-risk industries may also struggle to get compensation for the disease. While lawyers have noticed an increase in“white collar” cases of mesothelioma sufferers seeking compensation, a difficulty in such cases is establishing precisely whether and when any exposure took place that can be pinned to managerial negligence.

Northumberland teacher Patricia Cameron was exposed to asbestos when hanging pupils' clothes up to dry on asbestos lagging in the school boiler room in the 1970s. She was still working as a teacher when she began to suffer symptoms, including“return[ing] from work complaining of breathlessness”.

Following her death some 25 years after the exposure to asbestos ended, an inquest ruled that Cameron died of industrial disease – yet the subsequent claim for compensation ended without northumberland county council admitting liability . However, in this case, her family was still awarded compensation.

A further reason for the persistent underestimation of UK deaths from mesothelioma among school workers is that not all non-teaching staff are included in this data . Nineteen of the 84 cases we found in our review were non-teaching staff, including caretakers, cleaners and dinner ladies.

In fact, the nature of some of these roles may make exposure to asbestos more likely. Caretakers, cleaners and contractors such as electricians have identified exposure during work in boiler rooms, or around insulated heating pipes, as possible sources of exposure.

Margaret James had been a caretaker at a junior school in Llandudno from 1976 until 1992. Unknown to her, she was exposed to asbestos when completing numerous tasks including cleaning up after tradesmen following the building of a second school on the site. A legal report stated:

She became ill with shortness of breath and a chesty cough in 2019. Scans revealed a build-up of fluid on her lung, and a biopsy confirmed she had mesothelioma. The report concluded:

In April 2022, a UK Work & Pensions select committee report recommended the gradual removal of all asbestos from UK buildings over the next 40 years – with priority placed on the most hazardous types of asbestos, and also those buildings at particular risk, including schools.

The UK government rejected this recommendation , pointing to the very low risk of exposure where in-situ management is effectively implemented. The Health and Safety Executive suggests that a“rush to remove asbestos” would pose a more significant risk in terms of asbestos exposure. However, our analysis suggests this does not take full account of the condition, and day-to-day use, of many UK schools.

There are grounds to believe that the current policy of in-situ management is inadequate and, as buildings deteriorate, likely to become increasingly so. The policy came under further pressure in November 2022, when the first annual data analysis report into asbestos in uk buildings highlighted that:

The chair of the select committee, Stephen Timms MP, expressed extreme disappointment at the government's decision, commenting:

A parliamentary debate led by Loughborough MP jane hunt is due to discuss asbestos in the workplace on April 19. Trade unions whose members work in the education sector have long sought changes in the current policies of management and monitoring. As well as calling for the removal of asbestos from these environments, they also seek better monitoring of air quality in the meantime, and greater education of those who work and are schooled within them.

The permitted level of exposure to asbestos fibres in the air, set by the HSE, is currently in accordance with EU rules. However, these levels were based on what was technically feasible to monitor when the rules were set. This has now changed and many countries, including France, Holland and Germany, have much stricter levels.

the eu is proposing to lower its current maximum level, and is also encouraging the removal of asbestos from all buildings. No such proposals have been approved in the UK.

A spokesperson for HSE said:

HSE predicts that the total number of mesothelioma deaths across England, Scotland and Wales will decline steadily over the next three decades, with the rate falling faster among men than women. As asbestos is no longer used in new buildings, the number of people diagnosed after manufacturing or using asbestos products, such as (mostly male) construction workers, should tail off significantly.

However, the anticipated decline in mesothelioma cases may yet stall unless the issue of background exposure to asbestos in public buildings, including schools, is tackled. Despite the ongoing work of the parliamentary committee, there has been a striking lack of intervention and research in this area.

Peto has proposed new research to build on the inhaled particulates study (tips) . This would involve taking tissue samples from teachers without a mesothelioma diagnosis during lung surgery for other conditions, and analysing them for asbestos fibres as an indication of exposure in schools.

While there is no cure for mesothelioma, treatment innovations are progressing, including surgery trials such as mars 2 and targeted therapies including the nero , mitope and hit-meso trials. Carole Hagedorn, the teacher quoted at the start of this article, is reported to have undergone a radical pleurectomy in 2011 – a treatment which included having her lung lining removed in an attempt to eliminate much of the cancer.

But as she highlighted before her death, the most important issue is to stop more young people becoming victims in later life. It is unacceptable that the level of exposure of pupils in UK schools is still unknown – and imperative that the public are made aware of the risks of asbestos exposure in all working, living and educational environments, past and present.

Without a programme of safe removal of asbestos, there are likely to be many more experiences like that of Chris Willis. He was diagnosed with mesothelioma aged 29, and claimed this was from being exposed to asbestos while at school. He died in 2022, leaving behind a young family. Following his diagnosis, Willis had told the newcastle chronicle :
