UK Asbestos: the Definitive Guide (2004) UK ASBESTOS - THE DEFINITIVE GUIDE Working Party: Brian Gravelsons, Wendy Hawes, Sylwia Jakubowski, Anthony Kent, Julian Lowe (Chairman), Andy Macnair, Darren Michaels, Anita Morton, David Sanders, Philip Towell, Andy Whiting, James Widdows, Anthony Williams Keywords: “asbestos”, “asbestosis”, “mesothelioma” Summary: The estimated future cost to the UK insurance industry of asbestos-related claims is £4- £10b. Well over half of this relates to mesothelioma claims, numbers of which are predicted to continue to rise for the next ten years. By contrast, claims for other asbestos-related diseases, such as asbestosis, are expected to fall in the coming years, as the number of claims mirrors the declining use of asbestos since the 1970s. Most estimates of the future number of mesothelioma claims are based on the latest (2003) HSE projections. We have reproduced the HSE projections in a spreadsheet model to help practitioners understand the HSE model. This highlights the sensitivity of the projections to a number of key parameters. In particular, the future number of mesothelioma deaths is very dependent on how the disease continues to develop at older (80+) ages, with over half of all claims being in respect of those aged over 80 by the year 2020. The future number of mesothelioma deaths could easily be considerably higher or lower than the current projections, depending on the experience of this age group. We suspect that the variability of the HSE projections is greater than most practitioners who use the model would currently assume to be the case. In producing our estimates, we have used data collected via an anonymous survey from all major UK insurers, representing the majority of the UK market. We have also developed a simplified model of the emergence of asbestos-related diseases, to help project claim numbers for non-mesothelioma diseases. Our data survey has highlighted a range of practices in recording relevant information regarding asbestos-related claims. With such potentially large numbers at stake, the insurance industry would do well to improve its ability to record relevant information electronically. The range of potential outcomes for the cost to the insurance industry highlights the difficulty in assessing, let alone pricing, latent disease claims. This lends weight to the argument for potentially “separating” these types of claim from non-disease claims for the purpose of providing Employers’ Liability insurance. As well as our projections, the paper describes the main types of asbestos and asbestos- related diseases, health and safety regulations, claims handling protocols and relevant court cases. We’ve also reviewed information regarding the use of asbestos in the UK and around the world, other relevant data sources and given a brief overview of asbestos-related developments in the US.

INTRODUCTION 1.1 Overview of the paper We have tried to gather together as much information as possible about UK asbestos, particularly as it relates to UK insurers. We start by summarising what asbestos is, the types of disease it can lead to and the development of UK health and safety regulations in section 2. We then look at various insurance-related protocols for apportioning liability and providing compensation when insurers or employers are insolvent in section 3. Section 4 looks at a number of socio-economic aspects of asbestos - in particular a number of relevant UK court cases. This section includes a fair bit of information on two significant UK asbestos employers, Cape and Turner & Newall. It also looks at medical protocols for recognising asbestos disease (The Helsinki Criteria) and the state compensation available for asbestos-related diseases. Although the bulk of the paper relates to UK developments, we look at worldwide asbestos consumption/production and provide a quick overview of worldwide asbestos regulations and the compensation environment around Europe. Section 5 concentrates on reviewing papers that have made projections of UK mesothelioma deaths and describes some of the available data on asbestos claims and exposures. As part of the paper we conducted a survey of practitioners. We asked insurers to provide details of their asbestos-related claims in an “anonymous” fashion that let the working party look at aggregate data but not see any individual company contribution. We also asked a range of insurers, consultants and other interested parties for information about how they currently project asbestos liabilities. The results of the survey are detailed in section 6. In section 7 we describe a number of spreadsheet models we have used to make some industry-wide estimates of the cost of UK asbestos claims. In part these are based on models of the number of mesothelioma claims developed by Professor Peto and the HSE. The projections were calibrated using data provided as part of an industry-wide survey. We have expanded these models to include non- mesothelioma claims and added an estimate of cost as well as numbers of claims. We hope these spreadsheet models give actuarial practitioners a practical tool to assist in making asbestos-related projections. Although our main focus is the UK, developments in the US loom large in any discussion of asbestos, so we have provided an overview of the US asbestos environment in section 8. Finally, we include some thoughts and provocations relating to the insurance of latent claims in the UK in section 9. 1.2 Suggested sections for the reader-in-a-hurry From a little acorn, this paper has developed into a weighty tome… If someone wants to get a general background to asbestos and insurance-related issues in the UK without reading all 200+ pages, can we suggest the following as a useful subset to give a flavour of the main topics in the paper: • Sections 2.1, 2.2 and 2.3 on what is asbestos, types of asbestos-related disease and a chronology of UK use/regulation of asbestos. • Section 4.1 describes some of the main court cases regarding asbestos. • Section 4.3 gives a history of Turner & Newall, the UK’s largest asbestos producer and a thorny legal dilemma it is involved in. • Section 5.1 summarises the main previous estimates of UK mesothelioma deaths. • Sections 7.3 and 7.6 summarise the modelling work we have done and the industry-wide estimates we have produced. We have tried to provide a comprehensive Bibliography in Appendix I, including précis of some of the main papers we have drawn on. 1.3 Where to find the spreadsheet model(s) We hope to make the spreadsheet model we have developed available on the UK Actuarial profession’s web site at www.actuaries.org.uk under the “General Insurance” section. Failing that, interested parties are welcome to contact the Chairman for a copy at [email protected] The model lets an interested reader reproduce the UK market-wide estimates in the paper and produce reprojections based on their own chosen parameters. It can be used as a base to assist insurers, or other interested parties, in making projections of their own asbestos-related liabilities.

  • The Home Office and the Asbestos Industry Regulations, 1931
    Medical History, 1998, 42: 421-438 Too little, too late? The Home Office and the Asbestos Industry Regulations, 1931 PETER BARTRIP* Asbestos is the generic term for a group of fibrous minerals. Virtually indestructible and of high tensile strength, it is both fire and acid resistant, and yet can be spun into yarn and woven into cloth. Although there is evidence of the use of asbestos in the ancient world, it acquired commercial importance only in the late nineteenth century. Thereafter it was employed for numerous purposes, including in fire proofing, insulation and the automobile industry. But, while asbestos was in many ways a boon to humanity, it possesses one major drawback: exposure to its dust can cause fatal diseases, including fibrosis of the lungs (asbestosis) and cancer. As awareness of these dangers emerged, its use came to be first regulated and, subsequently, curtailed, so that today an asbestos industry hardly exists. While the asbestos industry might be virtually extinct, no branch of the history of occupational health has received more attention than asbestos-related disease. Much of this attention has focused on the USA, but several studies have discussed British developments, particularly during the first third of the twentieth century.1 When scholars independently investigate almost any subject, the usual outcome is debate and controversy. However, in relation to asbestos and health there is a high degree of consensus, not only that asbestos was "a bad thing" but that a chapter of errors and omissions occurred in the discovery and eradication of that bad thing. As far as early-twentieth-century Britain is concerned there is broad agreement on a number of points.

  • A Physical Paradox
    1 A Physical Paradox Asbestos...the world’s most wonderful mineral. A. L. Summers, Asbestos and the Asbestos Industry (1919). ASBESTOS WORKER’S DEATH: MINERAL PARTICLES IN LUNGS THE FIRST CAUSE Headline in the Rochdale Times, 2 Apr. 1924. the asbestos giant On a blustery and showery morning in August 1924, a funeral procession gathered in Rochdale, a town some 8 miles north of Manchester. After a service at a house in one of the better-class districts in the town, the mourners began the slow journey towards the town cemetery. It was a funeral cortège in the grand Victorian manner. Several hundred people had gathered in the town centre to pay their respects, and as the hearse headed past the Town Hall and out towards the cemetery it was followed by nearly sixty carriages and motor cars. At the graveside, fulsome tribute was paid to one of Rochdale’s most famous sons. The dead man was Sir Samuel Turner, an 84-year-old industrialist, who had died from a stroke the previous week at a hotel in Harrogate. The Turners were one of the town’s leading families: worthy Victorian ‘men of mark’, who could be said to have risen from humble origins by dint of their own ‘enterprise’ and practical skill. An honorary freeman and former mayor of Rochdale, Samuel Turner had been knighted in 1914, when he already had the wealth and trappings of a latter-day multi- millionaire. As a Methodist and Liberal, Turner had naturally balanced his wealth with paternalism and a commitment to the local community.

  • Is Occupational Asbestos Exposure an Under-Recognised Cause of Idiopathic Pulmonary Fibrosis?
    Is occupational asbestos exposure an under-recognised cause of idiopathic pulmonary fibrosis? Carl Jonathan Reynolds A thesis presented for the degree of Doctor of Philosophy Supervised by: Professor Paul Cullinan Dr Chris Barber Dr Sara De Matteis Department of Environmental and Occupational Medicine National Heart and Lung Institute Imperial College London, UK September 2020 Except where otherwise noted, content in this thesis is licensed under a Creative Commons Attribution 4.0 License (http://creativecommons.org/licenses/by/4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Copyright 2020, Carl Reynolds. 1 I, Carl Jonathan Reynolds confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. 2 Abstract The question of whether occupational asbestos exposure is an under- recognized cause of idiopathic pulmonary fibrosis arises because it is clinically and epidemiologically plausible, and consistent with fibre studies, case-control, and toxicological data. This thesis examines the question by means of a literature review and a novel hospital based case-control study, the idiopathic pulmonary fibrosis job exposures study (IPFJES). In a literature review and meta-analysis of studies reporting on occupational exposures in idiopathic pulmonary fibrosis (IPF) I found significant associ- ations with metal, wood, and stone dust, but not asbestos. However, there was considerable heterogeneity and confidence in the meta-analysis result is tempered by a high risk of bias arising from selection, lack of blinding, exposure misclassification, incomplete exposure data, and selective report- ing of exposures.

The reality of the situation is much graver than had been acknowledged by the authorities; the HSE figures for 2016 were 27% worse than forecast.6 While 85,000 deaths in 20 years are bad enough, this figure could be a dramatic underestimate of the true impact asbestos exposures have had in Britain. There are two main obstacles to gaining an accurate picture: the difficulty in identifying most asbestos-related diseases and the impossibility of distinguishing asbestos-related lung cancer from other types of lung cancer.
