Asbestos in Factories: Common Risks and How to Manage Them

Asbestos remains an important issue for many factories, manufacturing sites and industrial buildings across the UK. Although asbestos has been banned for many years, materials installed before the ban may still be present in older buildings, plant rooms, boiler houses, production areas, roofs, cladding, service ducts, pipework, machinery areas and maintenance workshops.

For factory owners, manufacturers, facilities managers, site engineers and health and safety teams, asbestos management is both a legal duty and a practical operational concern. Factories often involve heavy machinery, complex services, maintenance teams, contractors, high-level structures, heating systems, production lines and areas where older building materials may be hidden behind later upgrades.

The Health and Safety Executive states that asbestos can be found in any industrial or residential building built or refurbished before the year 2000, and that it may be present in many common materials used in the building trade.

This guide explains where asbestos is commonly found in factories, why manufacturing environments need careful asbestos management, what should happen before maintenance or refurbishment works, and how professional asbestos surveys, testing, removal and air monitoring can help keep industrial sites safe and compliant.

Why Asbestos Is a Particular Concern in Factories

Factories can present a higher level of asbestos complexity than many standard commercial buildings. This is because they often contain a mixture of building fabric, industrial plant, heating systems, production equipment, service routes and historic alterations.

A factory may have been extended, repaired, upgraded or reconfigured many times over several decades. Newer production lines may sit inside an older building shell. Modern cladding may cover earlier materials. Plant rooms may contain legacy insulation. Roof areas may include asbestos cement sheets that have weathered over time.

Asbestos-containing materials are not usually dangerous if they are in good condition and left undisturbed. The risk increases when they are damaged, drilled, cut, removed, broken, abraded or disturbed during maintenance, refurbishment, demolition or installation works.

In factories, asbestos may become a concern during:

• Planned maintenance
• Emergency repairs
• Machinery relocation
• Production line upgrades
• Boiler or plant room works
• Pipework replacement
• Electrical installation
• HVAC works
• Roof repairs
• Cladding replacement
• Fire safety upgrades
• Drainage works
• Mezzanine alterations
• Floor replacement
• Factory refurbishment
• Demolition or strip-out works

The operational impact can be significant. If suspected asbestos is discovered unexpectedly, work may need to stop, production areas may need to be isolated, contractors may be delayed, and urgent testing or removal may be required.

Early asbestos planning helps avoid disruption while protecting workers, contractors and site visitors.

Where Asbestos May Be Found in Factories

Asbestos can be present in both the building structure and older industrial equipment. The exact risks will depend on the age of the site, previous refurbishment works, the type of manufacturing carried out and the condition of materials.

Asbestos Cement Roof Sheets and Cladding

Asbestos cement roof sheets are common in older factories, warehouses and industrial units. They may be found on main production buildings, storage areas, loading bays, maintenance workshops, canopies and outbuildings.

Asbestos cement may also be present in wall cladding, gutters, downpipes, flues, ridge caps, soffits and external panels.

These materials are often lower risk when intact and undisturbed, but they can become more problematic when damaged, weathered, drilled, cut, broken or removed incorrectly. Roof access also creates additional risks because older asbestos cement sheets may be fragile.

Before roof repairs, solar panel installation, cladding replacement or demolition works, factory owners should check whether asbestos cement is present and whether a suitable asbestos survey has been completed.

Pipe Lagging and Thermal Insulation

Factories often have extensive pipework for steam, hot water, heating, process systems, compressed air, oils, chemicals or other services. Older pipe lagging and thermal insulation may contain asbestos, particularly in plant rooms, boiler houses, service ducts, basements and high-level pipe runs.

Pipe lagging can be higher risk because it may be more friable than asbestos cement. If it is damaged, deteriorating or disturbed during works, asbestos fibres may be released into the air.

Work involving older pipe insulation should not begin until asbestos information has been checked. Where records are incomplete, sampling and testing may be needed.

Boiler Houses and Plant Rooms

Boiler houses and plant rooms are common asbestos risk areas in factory environments. They may contain asbestos in pipe lagging, boiler insulation, asbestos insulation board, gaskets, rope seals, flues, fire protection materials and debris.

These areas are frequently accessed by engineers, maintenance staff, mechanical contractors and inspection teams. They may also be affected by heating upgrades, decarbonisation projects, boiler replacement, plant removal or service reconfiguration.

Crucial Environmental provides commercial asbestos surveys for factories and industrial buildings, helping site teams identify asbestos risks before plant room or service works begin.

Asbestos Insulation Board

Asbestos insulation board, often known as AIB, was widely used for fire protection, partitioning, panels, ceiling tiles, boxing, service risers and equipment enclosures. It may be present in offices within factories, control rooms, electrical rooms, production areas, fire doors, riser cupboards and plant areas.

AIB can present a higher risk if broken, drilled, cut or removed without proper controls. It can also be difficult to identify visually, especially where painted, covered or installed behind later finishes.

Sprayed Coatings and Fire Protection

Some older industrial buildings may contain sprayed asbestos coatings used for fire protection, insulation or acoustic control. These may be found on structural steelwork, ceilings, beams, columns or concrete surfaces.

Sprayed coatings are generally higher risk because they can release fibres more readily if damaged or disturbed. Any suspected sprayed coating should be assessed by competent asbestos specialists before work proceeds.

Floor Tiles, Adhesives and Screeds

Factories may contain asbestos in vinyl floor tiles, bitumen adhesive, older screeds or floor products. These materials may be hidden beneath newer flooring, machinery bases, production line areas or office finishes.

Flooring works, machine relocation, surface preparation and refurbishment can all disturb asbestos-containing flooring materials. Even where the asbestos content is relatively low, the work still needs proper assessment and controls.

Electrical Rooms and Control Panels

Older electrical rooms, switchgear areas, fuse boards and control panels may contain asbestos in backing boards, flash guards, arc shields, panels or insulation materials.

Electrical contractors and site engineers should check asbestos records before drilling, removing or modifying older electrical boards or surrounding materials.

Gaskets, Seals and Industrial Equipment

Asbestos was used in some gaskets, seals, packing materials, friction products, heat-resistant components and older machinery. This can be relevant in factories with legacy plant, industrial ovens, furnaces, kilns, presses, pumps, valves or process equipment.

The HSE advises that if a building was built after 2000, asbestos is unlikely in the building fabric, but old industrial machinery or equipment, such as industrial ovens, should still be considered.

This is particularly important when decommissioning, stripping out or moving older industrial equipment.

The Duty to Manage Asbestos in Factories

Factories are non-domestic premises, so the duty to manage asbestos is highly relevant. The HSE confirms that non-domestic premises include industrial and commercial buildings such as factories, warehouses, offices and shops.

The dutyholder is the person or organisation responsible for maintenance or repair of the premises. In a factory, this may be the building owner, landlord, manufacturer, site operator, tenant, facilities management provider or another party depending on lease and maintenance arrangements.

The duty to manage asbestos requires a practical process for identifying and controlling asbestos risk. This normally includes:

• Finding out whether asbestos-containing materials may be present
• Assessing their condition
• Keeping an asbestos register
• Preparing and maintaining an asbestos management plan
• Making asbestos information available to workers and contractors
• Reviewing and updating asbestos records
• Arranging further surveys before intrusive work
• Taking action if asbestos is damaged or likely to be disturbed

For factories, this process needs to work in real operational conditions. Maintenance staff, contractors, engineers and project managers must be able to access asbestos information before work starts.

Why an Asbestos Register Is Essential for Factory Sites

An asbestos register records known or presumed asbestos-containing materials within the site. It should identify where asbestos is located, what type of material it is, what condition it is in and what action is required.

For factories, the asbestos register should cover relevant areas such as:

• Production halls
• Plant rooms
• Boiler houses
• Service ducts
• Pipework routes
• Offices
• Welfare areas
• Workshops
• Loading bays
• Roof areas
• External cladding
• Electrical rooms
• Outbuildings
• Stores
• Basements and voids

A register is only useful if it is accurate, current and accessible. If it is kept in an office but not shared with maintenance contractors, it will not prevent accidental disturbance.

A good asbestos register should:

• Clearly identify asbestos locations
• Record the condition of materials
• Highlight areas that were not accessed
• Include photographs or location plans where useful
• Be available before maintenance works
• Be reviewed before contractor visits
• Be updated after testing, removal or refurbishment
• Be checked before emergency repairs or breakdown works

In a factory environment, urgent repairs are common. A production issue, roof leak, heating failure or electrical fault may require quick action. Even under time pressure, asbestos information should be checked before building materials are disturbed.

Management Surveys for Factories

An asbestos management survey is designed to help manage asbestos during normal occupation and routine maintenance. It supports the asbestos register and management plan.

The HSE’s asbestos survey guide, HSG264, is aimed at people carrying out asbestos surveys and those with responsibilities for managing asbestos in non-domestic premises under the Control of Asbestos Regulations 2012. It covers survey planning, carrying out surveys, survey reports and how dutyholders should use survey information.

For factories, a management survey may include accessible areas such as:

• Production spaces
• Offices
• Corridors
• Plant rooms
• Service risers
• Boiler houses
• Roof spaces
• Stores
• Welfare facilities
• External elevations
• Workshops
• Loading areas
• Common areas

The survey should identify materials that could be disturbed during normal use, inspection and routine maintenance. However, it may not include intrusive access into sealed voids, behind fixed panels, inside wall cavities or beneath machinery.

This is why management surveys should not be relied upon for major intrusive works unless they specifically cover the affected areas.

Refurbishment and Demolition Surveys Before Industrial Works

Factories often undergo refurbishment, reconfiguration and equipment upgrades. These works may be much more intrusive than routine maintenance.

A refurbishment and demolition asbestos survey may be required before:

• Factory strip-out
• Demolition works
• Plant room refurbishment
• Production line changes
• Machinery base removal
• Roof replacement
• Cladding replacement
• Floor removal
• Electrical rewiring
• HVAC upgrades
• Boiler replacement
• Mezzanine installation or removal
• Wall or partition alterations
• Service riser works
• Structural alterations
• Change of use projects

The survey should match the planned scope of works. If contractors will disturb walls, ceilings, floors, roof materials, pipework, panels, ducts or plant areas, the asbestos information must cover those specific locations.

Crucial Environmental provides asbestos surveys for industrial and manufacturing clients, including management surveys and refurbishment or demolition surveys before intrusive works.

Asbestos Testing in Factories

Asbestos testing confirms whether a suspect material contains asbestos. This is important because asbestos-containing materials can look very similar to non-asbestos products, especially in older industrial settings where materials may be painted, dirty, weathered or covered by later alterations.

Asbestos testing may be required where:

• A contractor finds suspect pipe lagging
• Roof sheets or cladding may contain asbestos cement
• An old panel or board is due to be removed
• A plant room material is damaged
• Floor tiles are being lifted
• Old gaskets or seals are found during plant works
• Existing asbestos records are incomplete
• A refurbishment survey identifies suspect materials
• Emergency repairs expose unknown materials

Crucial Environmental operates an in-house UKAS-accredited asbestos laboratory at its Worthing head office, enabling fast and reliable sample analysis for commercial and industrial clients. Fast testing can be particularly valuable in factory environments where downtime, production delays and contractor availability need to be managed carefully.

Managing Asbestos During Maintenance and Breakdown Works

Factory maintenance teams often need to respond quickly to operational issues. A leaking roof, failed heating system, damaged pipe, broken electrical supply or production line fault can create pressure to start work immediately.

However, urgent work should still include asbestos checks where the building fabric or older equipment may be disturbed.

Before maintenance or breakdown works begin, site teams should ask:

• Does the work involve drilling, cutting, scraping, removing or opening up materials?
• Has the work area been included in the asbestos register?
• Are there known asbestos-containing materials nearby?
• Are any areas marked as inaccessible or not surveyed?
• Will contractors disturb pipe lagging, panels, roof sheets or floor materials?
• Is sampling or further survey work needed before repairs continue?

This does not mean every maintenance task requires a new survey. It means asbestos information should be part of the maintenance decision-making process.

What to Do if Suspected Asbestos Is Found in a Factory

If suspected asbestos is found during factory works, the safest response is to stop and seek competent advice.

The correct steps are:

1. Stop work in the affected area.
2. Avoid disturbing the material further.
3. Restrict access if there is a possible fibre release risk.
4. Inform the site manager, dutyholder or responsible person.
5. Arrange assessment by a competent asbestos specialist.
6. Arrange sampling and laboratory analysis where required.
7. Follow specialist advice before work restarts.
8. Update the asbestos register if asbestos is confirmed.

Continuing work because of production pressure can make the situation worse. A short stop for testing or assessment is far preferable to an uncontrolled disturbance.

Crucial Environmental can support factories with rapid asbestos testing and advice where suspect materials are discovered during maintenance or refurbishment works.

When Asbestos Removal May Be Required in Factories

Not all asbestos needs to be removed immediately. In many cases, asbestos-containing materials can be managed in place if they are in good condition, unlikely to be disturbed and properly recorded.

However, removal may be required where asbestos is:

• Damaged
• Deteriorating
• Likely to be disturbed
• Preventing maintenance or installation works
• Located in a refurbishment area
• Present in a demolition area
• Creating ongoing operational restrictions
• Present in a high-risk material or poor condition

Some asbestos work must be carried out by a licensed asbestos removal contractor. The HSE states that most higher-risk work with asbestos must only be done by a licensed contractor. HSE examples of licensable work include removal of sprayed coatings, work disturbing pipe lagging, work involving loose fill insulation and certain work on asbestos insulating board.

Crucial Environmental provides commercial licensed asbestos removal for factories, manufacturing sites and industrial clients across the UK.

Air Testing and Reassurance Monitoring in Factories

Air testing and air monitoring may be required during or after asbestos removal, after suspected disturbance, or where reassurance is needed before an area is returned to use.

In factories, air testing and air monitoring may be relevant where:

• Licensed asbestos removal has taken place
• Works have occurred in plant rooms or production areas
• Suspected asbestos has been disturbed
• Contractors need reassurance before continuing work
• A production area needs to be handed back
• Work is taking place near occupied or operational areas
• Clearance procedures are required

Air monitoring can provide useful evidence that asbestos risks have been controlled. This can be especially important where production needs to restart, contractors need to re-enter an area, or employees require reassurance after asbestos works.

Reducing Downtime During Asbestos Works

Downtime is a major concern for factory operators. Asbestos issues can affect productivity, customer commitments, logistics, shift patterns and contractor scheduling.

The best way to reduce asbestos-related downtime is to plan early.

Factories can reduce disruption by:

• Reviewing asbestos records before planned works
• Completing surveys before contractor mobilisation
• Testing suspect materials early
• Scheduling asbestos removal around shutdown periods
• Coordinating works with production planning
• Using clear exclusion zones and phased works
• Planning air monitoring and handover requirements
• Ensuring contractors have asbestos information before arrival
• Updating records immediately after works

Where asbestos is identified early, removal or management works can often be integrated into planned maintenance shutdowns or phased around operational needs.

Asbestos Risks During Factory Refurbishment

Factory refurbishment can involve a wide range of intrusive tasks. These may include removing old offices, replacing floors, improving ventilation, upgrading electrics, installing new machinery, altering production lines or improving fire safety.

Asbestos risk should be reviewed before refurbishment design and contractor pricing. If asbestos is found late, the project may face additional costs, delays and design changes.

Before refurbishment starts, factory operators should check:

• Whether the existing asbestos register is current
• Whether the proposed works are intrusive
• Whether a refurbishment survey is required
• Whether asbestos removal must happen before other trades start
• Whether works can be phased to keep production running
• Whether air testing or clearance is required
• Whether asbestos waste disposal has been planned
• Whether the construction phase plan includes asbestos controls

Crucial Environmental supports Industrial & Manufacturing clients with asbestos surveys, testing, removal and air monitoring for factory refurbishment projects.

Asbestos in Factory Roofs and External Building Fabric

Industrial roofs and external cladding deserve particular attention. Older factories often have large roof areas, and asbestos cement may be widespread.

Roof works may be required due to:

• Leaks
• Storm damage
• Corrosion
• Solar panel installation
• Insulation upgrades
• Rooflight replacement
• Structural repairs
• Gutter replacement
• Cladding replacement
• Full roof replacement

Before any roof work begins, asbestos cement materials should be identified and their condition assessed. Contractors should not pressure wash suspected asbestos cement roofing, and drilling or cutting should be avoided unless properly assessed and controlled.

If roof sheets are damaged or need removal, asbestos specialists can advise on the safest approach.

Asbestos and Older Industrial Equipment

Asbestos may also be associated with old industrial equipment rather than the building itself. This is particularly relevant for factories with long-standing machinery or specialist process equipment.

Potential asbestos-containing components may include:

• Gaskets
• Seals
• Brake or clutch components
• Heat shields
• Insulation pads
• Packing materials
• Furnace or oven linings
• Boiler components
• Kiln materials
• Valve and pump seals
• Electrical insulation components

When old equipment is decommissioned, dismantled, moved or scrapped, asbestos risk should be considered. This is especially important where equipment predates 2000 or has an unknown maintenance history.

Practical Asbestos Checklist for Factory Owners and Operators

Factory owners, operators and facilities teams should consider the following checks:

• Confirm whether the factory was built or refurbished before 2000.
• Check whether old industrial machinery or equipment could contain asbestos components.
• Maintain an up-to-date asbestos register.
• Keep an asbestos management plan in place.
• Review asbestos information before maintenance, refurbishment or installation works.
• Arrange management surveys where records are missing or outdated.
• Arrange refurbishment or demolition surveys before intrusive works.
• Use UKAS-accredited asbestos testing for suspect materials.
• Provide asbestos information to contractors before work begins.
• Stop work immediately if suspected asbestos is discovered.
• Plan asbestos removal before refurbishment, roof works or demolition.
• Use licensed asbestos removal contractors where required.
• Consider air testing after removal or suspected disturbance.
• Update asbestos records after testing, removal or refurbishment.
• Coordinate asbestos works with production planning to reduce downtime.

This approach helps factories manage asbestos safely while supporting operational continuity.
