Asbestos in Pre-1980s Factories and Industrial Sites: What You Need to Know
If you manage or own a factory, warehouse, or industrial site built before 1980, asbestos in pre-1980s factories is not a distant concern — it is almost certainly your reality. The UK’s industrial heritage is remarkable, but it comes with a legacy that demands serious attention. Asbestos was woven into the fabric of industrial construction for decades, and the structures left behind continue to pose genuine risks to workers, contractors, and anyone who enters these buildings.
This is not just about the main building. Chimneys, outbuildings, storage tanks, pipe runs, and ancillary structures on older industrial sites can all harbour asbestos-containing materials (ACMs). Understanding where to look, what your legal obligations are, and how to manage the risk properly is essential for any responsible site manager or property owner.
Why Pre-1980s Factories Are Particularly High Risk
Asbestos was the go-to material for industrial construction throughout much of the twentieth century. It was cheap, durable, fire-resistant, and an excellent insulator — qualities that made it almost irresistible to industrial builders. By the time its devastating health effects were fully understood, it had been incorporated into thousands of factories, mills, and manufacturing plants across the UK.
The UK banned the use of all forms of asbestos in 1999. Any building constructed or significantly refurbished before that date could contain ACMs, but factories built before 1980 are in a category of their own. These sites were often constructed during the peak of asbestos use, and the materials installed then are now ageing, becoming brittle, and increasingly likely to release fibres if disturbed.
When asbestos fibres become airborne and are inhaled, they can cause serious and fatal diseases including mesothelioma, asbestosis, and lung cancer. These diseases have long latency periods, meaning the consequences of exposure today may not become apparent for decades. That is precisely why managing asbestos in pre-1980s factories must be treated as an urgent priority, not something to defer.
Where Asbestos Hides in Older Industrial Buildings
Asbestos in pre-1980s factories was not confined to one or two obvious locations. It was used extensively across the entire site, often in places that are easily overlooked during routine inspections. Knowing where to look is the first step towards effective management.
Structural and Roofing Materials
Asbestos cement was one of the most widely used industrial building materials. Corrugated asbestos cement roof sheets and wall cladding panels were standard on factory buildings, agricultural units, and warehouses throughout the mid-twentieth century. These sheets are often still in place, weathered and fragile, on older industrial sites.
Flat roofing systems frequently incorporated asbestos in bitumen-based compounds. Even where the roof has been partially replaced, the underlying layers may still contain ACMs. Guttering, downpipes, and rainwater goods were also commonly manufactured from asbestos cement during this period.
Insulation and Fireproofing
Industrial processes generate significant heat, and asbestos was the insulation material of choice for boilers, pipework, ductwork, and process equipment. Sprayed asbestos coatings were applied to structural steelwork as fireproofing — a practice that was widespread in factories built between the 1950s and 1970s. This sprayed coating is among the most hazardous forms of ACM because it is friable and can release fibres very easily when disturbed.
Lagging on pipes and vessels, insulating board used in ceiling tiles and partition walls, and thermal insulation around furnaces and kilns are all areas where asbestos is commonly found in older industrial settings.
Non-Building Structures on Industrial Sites
Beyond the main factory building, industrial sites often include a range of ancillary structures that carry their own asbestos risks. These are frequently overlooked when site managers think about their asbestos management obligations.
- Industrial chimneys: Asbestos was used extensively in the linings and fireproofing of industrial chimneys. Deteriorating chimney linings can shed fibres into the surrounding environment, particularly during demolition or repair work.
- Asbestos cement water tanks: Cold water storage tanks made from asbestos cement were standard in industrial and commercial buildings. Damage or deterioration can release fibres into the water supply and the surrounding structure.
- Outbuildings, garages, and storage structures: Smaller structures on industrial sites — security huts, transformer housings, storage sheds — were often built using the same asbestos cement materials as the main factory.
- Underground pipe runs and service ducts: Asbestos cement pipes were widely used for drainage and water supply. Excavation work on older industrial sites can disturb these without warning.
- Power generation equipment: Older on-site generators and electrical switchgear frequently incorporated asbestos-based insulation and gaskets.
Floor Tiles, Adhesives, and Decorative Finishes
Vinyl floor tiles produced before the 1980s often contained asbestos, as did the adhesives used to bond them. In industrial settings, these tiles were applied in offices, canteens, and welfare facilities within the factory complex. The tiles themselves may be relatively stable, but the adhesive layer beneath is often highly friable and dangerous when the tiles are lifted.
Your Legal Obligations Under the Control of Asbestos Regulations
If you are responsible for a non-domestic premises — including a factory, warehouse, or industrial unit — the Control of Asbestos Regulations place a legal duty on you to manage asbestos. This is known as the Duty to Manage, and it applies to all non-domestic premises regardless of whether you own or lease the building.
The Duty to Manage requires you to:
- Take reasonable steps to find out if ACMs are present and assess their condition.
- Presume that materials contain asbestos unless there is strong evidence to the contrary.
- Prepare and maintain an up-to-date written asbestos management plan.
- Share information about the location and condition of ACMs with anyone who might disturb them.
- Monitor the condition of known ACMs regularly.
HSE guidance, specifically HSG264, sets out how asbestos surveys should be conducted and what they must cover. Failure to comply with the Control of Asbestos Regulations is a criminal offence that can result in significant fines and prosecution. More importantly, non-compliance puts lives at risk.
For sites where refurbishment or demolition work is planned, the legal requirements go further. A refurbishment survey is required before any work begins that might disturb the fabric of the building. This type of survey is intrusive and designed to locate all ACMs in the areas to be affected by the works.
Types of Asbestos Survey for Industrial Sites
Not all asbestos surveys are the same, and choosing the right type for your industrial site is critical. The two primary survey types are defined in HSG264, and each serves a distinct purpose.
Management Survey
A management survey is the standard survey required for the ongoing management of a building in normal use. It identifies the location, extent, and condition of ACMs that could be disturbed during everyday activities, and it provides the foundation for your asbestos management plan and register. For most occupied industrial premises, this is the starting point.
Refurbishment and Demolition Survey
If you are planning any work that will disturb the structure — from a minor partition removal to a full factory demolition — a refurbishment survey is legally required before work commences. This survey is far more intrusive than a management survey and may involve destructive inspection techniques to locate ACMs hidden within the building fabric.
Re-inspection Survey
Once ACMs have been identified and a management plan is in place, those materials must be monitored regularly to check that their condition has not deteriorated. A re-inspection survey provides a formal, documented assessment of known ACMs and updates the risk rating in your asbestos register. For industrial sites with multiple ACMs, annual re-inspections are typically recommended.
Asbestos Testing: When You Need It and How It Works
Visual identification of asbestos is not reliable. Many ACMs look identical to non-asbestos materials, and the only way to confirm the presence of asbestos is through laboratory analysis of a physical sample. Asbestos testing involves taking a small sample of the suspect material and having it analysed under polarised light microscopy (PLM) at a UKAS-accredited laboratory.
For industrial site managers who want to test specific materials before commissioning a full survey, a testing kit allows you to collect samples safely and send them for laboratory analysis. This can be a cost-effective way to get clarity on specific materials of concern.
For a broader assessment of an industrial site, professional asbestos testing carried out as part of a full survey is always the most reliable and legally defensible approach. Surveyors will take representative samples from all suspect materials, ensuring that nothing is missed.
Managing Asbestos in Pre-1980s Factories: Practical Guidance
Identifying asbestos is only the beginning. Once ACMs have been found and assessed, you need a clear plan for managing them safely. Here is what effective asbestos management on an industrial site looks like in practice.
Maintain an Accurate Asbestos Register
Your asbestos register should record the location, type, extent, and condition of every ACM on site. It must be kept up to date and made available to anyone who might disturb the materials — including maintenance contractors, electricians, plumbers, and construction workers. An outdated or incomplete register is a liability, not a safeguard.
Implement a Permit-to-Work System
On industrial sites, a permit-to-work system for any activities that might disturb ACMs is an essential control measure. Before any maintenance or construction work begins, the asbestos register should be consulted, and workers should be briefed on the location of any ACMs in the work area.
Do Not Disturb Stable ACMs Unnecessarily
Not all ACMs need to be removed immediately. If an ACM is in good condition and is unlikely to be disturbed, managing it in place is often the safest option. The priority is to prevent fibre release, not to remove every trace of asbestos regardless of risk. Your surveyor will assign a risk rating to each ACM to help you prioritise your response.
Use Licensed Contractors for High-Risk Work
The Control of Asbestos Regulations specify which types of asbestos work require a licensed contractor. Work involving sprayed coatings, pipe lagging, and asbestos insulating board — all common in pre-1980s factories — almost always falls into the licensed category. Only a contractor licensed by the HSE should undertake this work. Where asbestos removal is required, using a licensed and experienced contractor is not optional — it is a legal requirement.
Consider a Fire Risk Assessment Alongside Asbestos Management
Older industrial buildings often present multiple overlapping risks. A fire risk assessment should be carried out alongside your asbestos management programme, as fire damage to ACMs can cause widespread fibre release. Integrating both assessments gives you a complete picture of the hazards present on your site.

Frequently Asked Questions
Is asbestos definitely present in my pre-1980s factory?
Not necessarily, but the probability is high. Asbestos was used so extensively in industrial construction before the 1980s that its presence should be presumed unless a professional survey or laboratory testing confirms otherwise. The Control of Asbestos Regulations require you to presume asbestos is present if there is no strong evidence to the contrary.
Do I need to remove all the asbestos in my factory immediately?
No. If ACMs are in good condition and are not likely to be disturbed, managing them in place is often the appropriate course of action. A professional asbestos management survey will assign a risk rating to each ACM, allowing you to prioritise your response. Removal is required when materials are in poor condition, are at risk of damage, or when refurbishment or demolition work is planned.
What happens if I disturb asbestos during maintenance work without knowing it was there?
If asbestos is disturbed unexpectedly, work should stop immediately, the area should be vacated, and you should contact a licensed asbestos contractor to assess the situation. You may also be required to notify the HSE depending on the nature and extent of the disturbance. This is precisely why having an up-to-date asbestos register and briefing contractors before work begins is so important.
How often do I need to re-inspect known ACMs on my industrial site?
The frequency of re-inspections depends on the condition and risk rating of the ACMs identified in your initial survey. For most industrial sites with multiple ACMs, annual re-inspections are recommended as a minimum. Your asbestos management plan should specify the re-inspection schedule for each material.
Can I collect asbestos samples myself?
In some circumstances, non-licensed persons can collect samples from certain materials, but this must be done using correct containment procedures to prevent fibre release. A testing kit provides the equipment and instructions needed for safe sample collection. However, for a legally compliant asbestos register and management plan, samples should be collected by a qualified surveyor as part of a formal survey.
