When an Asbestos Incident Strikes: What Shipbuilding History Teaches Us About Protecting People Today
An asbestos incident in a shipyard, dockyard, or ageing industrial building is not a theoretical risk — it is a documented reality with consequences that can take decades to emerge. The shipbuilding industry offers one of the starkest lessons in what happens when asbestos exposure goes unmanaged, and those lessons remain urgently relevant for anyone responsible for maintaining older properties today.
From the 1930s through to the 1980s, asbestos was woven into the fabric of British shipbuilding. It insulated engine rooms, wrapped boilers, lined pipe systems, and appeared in electrical wiring. Workers breathed in fibres daily, often without protective equipment and without any awareness of the danger.
The consequences — mesothelioma, lung cancer, asbestosis — emerged silently, sometimes 40 or 45 years after the original exposure. Understanding how asbestos incidents unfolded in this industry, and how they continue to affect people today, is essential reading for property managers, facilities teams, and anyone working in or around buildings constructed before 2000.
The Scale of Asbestos Use in British Shipbuilding
Asbestos was not used sparingly in shipbuilding — it was used everywhere. The Royal Navy incorporated it heavily into submarines, aircraft carriers, frigates, and support vessels. Its fire-resistant and heat-insulating properties made it appear indispensable in environments where fire suppression and thermal management were critical to survival.
Engine rooms were lined with it. Boiler lagging was made from it. Pipe insulation, gaskets, brake pads, clutch components, and electrical insulation all contained asbestos in various forms.
The confined spaces aboard submarines and warships meant that any disturbance of asbestos-containing materials released fibres into air that crews breathed continuously, with nowhere to go. Commercial shipyards were no different. Workers repairing and maintaining vessels spent entire careers cutting, drilling, and handling materials saturated with asbestos.
Which Asbestos Types Were Most Common?
Several types of asbestos appeared in shipbuilding applications, and all three were capable of causing fatal disease:
- Crocidolite (blue asbestos) — considered the most hazardous, widely used in pipe lagging and insulation boards
- Amosite (brown asbestos) — used extensively in thermal insulation and ceiling tiles
- Chrysotile (white asbestos) — the most commonly used type overall, found in textiles, gaskets, and roofing materials
All three types were present in shipyards. There is no safe type of asbestos, and any asbestos incident involving any of these materials must be treated with the same level of urgency.
Who Faced the Greatest Risk from an Asbestos Incident?
The workers most heavily exposed were those who disturbed asbestos-containing materials most frequently. In shipbuilding, that meant several distinct groups — each with their own pattern of exposure and associated health outcomes.
Shipyard Construction and Repair Workers
Workers who built and repaired vessels during the peak decades of asbestos use handled lagging, insulation, and structural components throughout their working lives. Repair work was particularly hazardous — cutting through old insulation, removing lagging from pipes, or working in confined spaces where previous asbestos disturbance had occurred all created high concentrations of airborne fibres.
Workers who carried out these tasks daily faced cumulative exposures far beyond what any safe threshold would permit. The long-term toll on this workforce was severe and, in many cases, fatal.
Naval Personnel
Royal Navy personnel lived and worked aboard vessels containing asbestos for months at a time. Engine room staff, engineers, and maintenance crew faced the most intense exposure, but even those in less obviously hazardous roles breathed the same air in the same enclosed spaces.
The Navy now operates under the Control of Asbestos Regulations, with strict protocols for surveying, managing, and removing asbestos from ageing vessels. Training is mandatory. Licensed specialists carry out all removal work. The contrast with historical practice could not be more stark.
Dockyard Maintenance Teams
Dockyard workers who maintained and refitted vessels faced long-term exposure across entire careers. Many worked without respiratory protection. The dust generated by cutting, grinding, and removing asbestos-containing materials accumulated in their lungs over years and decades.
Even today, workers in dockyards and industrial facilities may encounter legacy asbestos in older structures and vessels. This is why professional asbestos removal by licensed contractors remains essential whenever asbestos-containing materials are disturbed or need to be taken out of service.
Families of Workers
One of the most disturbing aspects of the shipbuilding asbestos story is the extent to which exposure spread beyond the workplace. Research from the mid-twentieth century found that a significant proportion of workers’ wives showed signs of lung disease — the result of fibres brought home on work clothing, in hair, and on skin.
Children of workers were also affected. Cases of asbestosis were identified among workers’ children who had never set foot in a shipyard. Secondary exposure of this kind demonstrates that an asbestos incident at work is never contained solely to the workplace.
The Health Consequences of Long-Term Asbestos Exposure
The diseases caused by asbestos exposure are serious, often fatal, and characterised by long latency periods. This is what makes asbestos so particularly dangerous — by the time symptoms appear, the damage has been accumulating for decades.
Mesothelioma
Mesothelioma is a cancer of the lining of the lungs, abdomen, or heart. It is almost exclusively caused by asbestos exposure. It is aggressive, difficult to treat, and typically diagnosed at an advanced stage because symptoms do not appear until the disease is well established.
Shipyard workers from the peak exposure decades continue to be diagnosed with mesothelioma today. The latency period between first exposure and diagnosis can be 30 to 45 years, meaning that workers exposed in the 1970s and 1980s are still receiving diagnoses now.
Lung Cancer
Asbestos exposure significantly increases the risk of lung cancer, and this risk is compounded substantially in workers who also smoked. The combination of asbestos fibres and tobacco smoke creates a synergistic effect that multiplies risk well beyond what either factor would produce alone.
Workers in shipyards during the mid-twentieth century faced elevated rates of lung cancer compared to the general population. Many of these cancers were never formally attributed to asbestos exposure, meaning the true toll of the industry’s asbestos use is likely higher than recorded figures suggest.
Asbestosis
Asbestosis is a chronic fibrotic lung disease caused by the inhalation of asbestos fibres over time. The fibres cause scarring of lung tissue, progressively reducing the lungs’ ability to function. Symptoms include breathlessness, persistent cough, and chest tightness — all of which worsen over time.
There is no cure for asbestosis. Management focuses on slowing progression and managing symptoms. For workers who spent careers in shipyards, the cumulative fibre burden in their lungs was often substantial.
Other Asbestos-Related Conditions
Beyond the three primary conditions, asbestos exposure is associated with pleural plaques, pleural thickening, and pleural effusion — all conditions affecting the lining of the lungs. These may not always cause significant symptoms but are markers of exposure and can affect lung function over time.
Research has also linked asbestos exposure to cancers of the larynx, ovaries, and other organs, though the strength of evidence for these associations varies.
Why Asbestos Fibres Are So Dangerous: The Biological Mechanism
Understanding why asbestos causes disease helps explain why any asbestos incident must be taken seriously, even when exposure appears minor or brief.
When asbestos fibres are inhaled, the smallest ones penetrate deep into lung tissue, reaching the alveoli and pleural lining. The body’s immune system recognises these fibres as foreign but cannot break them down or remove them. Instead, immune cells attempt to engulf the fibres, fail, and die — triggering chronic inflammation.
This sustained inflammatory state damages surrounding cells over time. DNA damage accumulates. Cell mutations occur. Over decades, these changes can give rise to malignant tumours. The fibres themselves remain in the tissue throughout this entire process, continuing to drive inflammation long after the original exposure.
This persistence is why latency periods are so long, and why even a single significant asbestos incident can carry consequences that emerge 30 or 40 years later.
Modern Regulations: What the Law Requires Following an Asbestos Incident
The regulatory landscape governing asbestos in the UK has transformed significantly since the peak years of shipbuilding asbestos use. The Control of Asbestos Regulations establish a clear legal framework that applies to all non-domestic premises, including industrial sites, dockyards, and commercial buildings.
The Duty to Manage
Under the Control of Asbestos Regulations, anyone with responsibility for maintaining non-domestic premises has a legal duty to manage asbestos. This means identifying whether asbestos is present, assessing its condition and risk, and putting in place a written management plan.
For older industrial buildings — including those associated with the maritime industry — this duty is particularly significant. Asbestos may be present in forms that are not immediately obvious, and only a properly conducted survey can establish what is there and where. A management survey is the starting point for fulfilling this legal obligation.
Survey Requirements
HSE guidance document HSG264 sets out the standards for asbestos surveys. There are two main types:
- Management surveys — identify asbestos-containing materials that could be disturbed during normal use and maintenance
- Refurbishment and demolition surveys — required before any work that will disturb the fabric of a building
Before any significant structural work or demolition, a demolition survey must be completed to ensure all asbestos-containing materials are identified and safely managed before work begins.
Any materials identified must be recorded in an asbestos register, assessed for condition and risk, and managed accordingly. This register must be made available to anyone likely to disturb the material — including contractors.
Licensed Removal
Certain categories of asbestos work can only be carried out by HSE-licensed contractors. This includes work with sprayed asbestos coatings, asbestos insulation, and asbestos insulating board. In shipbuilding and dockyard contexts, where these materials were used extensively, licensed removal is frequently required.
Attempting to remove or disturb these materials without the appropriate licence is a criminal offence under the Control of Asbestos Regulations, and it places workers and occupants at serious risk of exposure.
What to Do If You Suspect an Asbestos Incident Has Occurred
If asbestos-containing materials have been disturbed — whether accidentally during maintenance work, as a result of damage, or through unauthorised removal — the response must be immediate and methodical. Acting quickly and correctly can limit the extent of exposure and help you meet your legal obligations.
- Stop work immediately. Anyone in the affected area should leave without disturbing materials further.
- Seal the area. Prevent access until a qualified professional has assessed the situation.
- Do not attempt to clean up. Vacuuming or sweeping can spread fibres further and increase exposure risk.
- Contact a licensed asbestos surveyor. A qualified professional will assess the extent of the disturbance and advise on next steps.
- Notify the relevant parties. Depending on the circumstances, you may need to inform your employer, the HSE, or your local authority.
- Arrange air monitoring. A qualified analyst can take air samples to determine whether fibre concentrations in the affected area are safe.
- Document everything. Keep a detailed record of what happened, who was present, and what steps were taken. This is essential for legal compliance and any future insurance or compensation claims.
Speed matters. The longer a contaminated area remains unsealed, the greater the risk of fibres spreading to adjacent spaces and increasing the number of people exposed.
Lessons from Shipbuilding: What Property Managers Must Take Away
The shipbuilding industry’s asbestos legacy is not just a matter of historical record. It is an active reminder that the consequences of poor asbestos management are long-lasting, severe, and entirely preventable with the right approach.
Any building constructed before the year 2000 may contain asbestos-containing materials. This includes offices, schools, hospitals, industrial units, warehouses, and residential blocks. The presence of asbestos does not automatically create risk — but disturbance without proper management does.
Property managers and facilities teams should ensure the following are in place:
- An up-to-date asbestos register based on a professionally conducted survey
- A written asbestos management plan reviewed at regular intervals
- Clear procedures for contractors working in or around asbestos-containing materials
- Trained staff who know how to recognise potential asbestos-containing materials and respond to a suspected asbestos incident
- Access to a licensed asbestos surveying company for ongoing support and emergency response
If you manage properties across multiple locations, professional survey coverage is available nationwide. Whether you need an asbestos survey in London, an asbestos survey in Manchester, or an asbestos survey in Birmingham, qualified surveyors can provide the assessments you need to stay compliant and protect the people in your buildings.
Frequently Asked Questions
What counts as an asbestos incident?
An asbestos incident occurs when asbestos-containing materials are disturbed in a way that releases fibres into the air. This can happen accidentally — during drilling, cutting, or demolition work — or as a result of damage, deterioration, or unauthorised removal. Even minor disturbances can release significant quantities of fibres, which is why any suspected incident should be treated seriously and assessed by a qualified professional.
How long after an asbestos incident can health problems develop?
Asbestos-related diseases have extremely long latency periods. Mesothelioma, for example, can take between 30 and 45 years to develop after the original exposure. Asbestosis and lung cancer can also take decades to manifest. This means that health problems arising from an asbestos incident may not become apparent until many years after the event, which is why prevention and proper management are so critical.
Do I need to commission a survey before starting refurbishment work on an older building?
Yes. Under HSE guidance document HSG264 and the Control of Asbestos Regulations, a refurbishment and demolition survey is legally required before any work that will disturb the fabric of a building. This applies to buildings of any age, but is especially critical for properties built before 2000. Proceeding without a survey puts workers at risk and exposes duty holders to significant legal liability.
Is asbestos only found in industrial buildings?
No. Asbestos was used in a wide range of building types, including domestic properties, schools, hospitals, offices, and retail premises. It appears in floor tiles, ceiling tiles, pipe lagging, roof sheets, textured coatings such as Artex, and many other materials. Any building constructed or refurbished before the year 2000 should be assessed for the presence of asbestos-containing materials before any maintenance or refurbishment work is carried out.
What should I do if I think I’ve been exposed to asbestos during an incident at work?
You should inform your employer immediately and ensure the incident is formally recorded. Seek medical advice from your GP, explaining the nature and circumstances of the exposure. Keep a record of when and where the exposure occurred, and what materials were involved. Your employer has a legal duty to investigate the incident, take remedial action, and report certain types of asbestos exposure to the HSE under RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations).
