Asbestos Fire Suits, PPE and Worker Protection During Property Maintenance
Asbestos fire suits have a long and complicated history. Once praised for their heat-resistant properties, these suits were worn by firefighters and industrial workers across the UK for decades — yet the very material that made them effective was quietly destroying the lungs of the people wearing them. Today, the term asbestos fire suits serves as a sobering reminder of why proper asbestos management during property maintenance is not just a legal obligation, but a matter of life and death.
If you manage, own or maintain a building constructed before 2000, there is a real possibility that asbestos-containing materials (ACMs) are present. Understanding how to protect workers — and what lessons the era of asbestos fire suits teaches us — is essential for any dutyholder.
The Legacy of Asbestos Fire Suits and Why It Still Matters
Asbestos fire suits were standard issue for firefighters and industrial workers throughout much of the 20th century. Asbestos fibres are naturally heat-resistant, which made them seem ideal for protective clothing in high-temperature environments. The suits were woven from chrysotile (white asbestos) or amosite (brown asbestos) fibres, and workers wore them with confidence — often for years on end.
The problem was that every time those suits were donned, adjusted, or stored, fibres were released into the air. Workers inhaled microscopic asbestos fibres without any awareness of the damage being done. The diseases caused — mesothelioma, asbestosis and lung cancer — can take decades to develop, meaning many workers only received a diagnosis long after retirement.
The UK banned the use of all forms of asbestos in 1999. But the buildings, equipment and legacy materials from that era remain. That is why property maintenance work today demands rigorous asbestos management — because disturbing ACMs without proper controls recreates exactly the kind of exposure that asbestos fire suits once caused.
Identifying Asbestos Risk Before Maintenance Work Begins
No maintenance work should begin on an older building without first establishing whether asbestos is present. This is not optional — it is a legal duty under the Control of Asbestos Regulations. Buildings constructed before 2000 may contain ACMs in a wide variety of locations, including ceiling tiles, pipe lagging, floor tiles, roofing felt, textured coatings and insulation boards.
The presence of asbestos is not always obvious from a visual inspection alone. A qualified surveyor must be commissioned to carry out a formal assessment before any intrusive work begins.
High-Risk Occupations and Environments
Certain workers face elevated asbestos exposure risk simply by virtue of their trade. Construction workers, electricians, plumbers, joiners and HVAC engineers regularly disturb hidden ACMs during routine maintenance tasks. Firefighters — the very profession that once relied on asbestos fire suits — continue to face risks when attending fires in older buildings where asbestos becomes airborne in the heat.
Employers in these sectors have a heightened duty of care, and risk assessments must account for the specific tasks being carried out and the likelihood of disturbing ACMs in the process.
How to Determine Whether Asbestos Is Present
Dutyholders must carry out a thorough assessment before any work begins. The process typically involves:
- A visual inspection of the building fabric to identify suspect materials
- Material sampling by a qualified surveyor, followed by laboratory analysis
- A full asbestos survey carried out in line with HSG264 guidance
- Maintaining an up-to-date asbestos register recording the location, type and condition of all ACMs
Assume all suspect materials contain asbestos until laboratory testing proves otherwise. This precautionary approach is both legally sound and practically sensible.
For buildings across the capital, a qualified asbestos survey London team can carry out HSG264-compliant surveys to give you a clear picture of what is present before any work begins. For properties in the Midlands, an asbestos survey Birmingham specialist can provide the same standard of professional assessment. For premises in the North West, an asbestos survey Manchester team will ensure your building is assessed to the same rigorous standard.
The Regulatory Framework: What the Law Requires
The Control of Asbestos Regulations places clear legal duties on employers, building owners and those in control of premises. Ignorance of the law is not a defence, and the Health and Safety Executive (HSE) takes enforcement seriously.
Legal Duties for Dutyholders
If you are a building owner, landlord or facilities manager responsible for non-domestic premises, you are likely a dutyholder under the regulations. Your core obligations include:
- Assessing whether ACMs are present in the premises
- Producing and maintaining an asbestos management plan
- Ensuring the plan is reviewed regularly and updated when circumstances change
- Sharing information about ACM locations with anyone who may disturb them
- Arranging licensed removal where required
The asbestos management plan is a living document, not a one-time exercise. It should be reviewed at least annually and updated whenever maintenance work is completed, ACMs are disturbed, or new information becomes available.
Compliance Requirements in Practice
Meeting your legal duties involves a structured approach across several areas:
- Conduct asbestos surveys — commission a management survey for occupied premises, and a refurbishment survey or demolition survey before any intrusive work begins
- Develop an asbestos management plan — document all ACMs, their condition and the control measures in place
- Provide asbestos awareness training — all workers who may encounter ACMs must receive appropriate training
- Supply and maintain PPE — including respiratory protective equipment (RPE) and protective overalls
- Implement engineering controls — such as local exhaust ventilation and HEPA filtration
- Ensure safe disposal — asbestos waste must be disposed of by licensed contractors in accordance with HSE guidance
- Maintain detailed records — keep logs of asbestos-related activities for at least 40 years
- Arrange health surveillance — for workers who are regularly exposed to asbestos
From Asbestos Fire Suits to Modern PPE: What Workers Should Wear Today
The shift from asbestos fire suits to modern PPE represents one of the most significant improvements in worker safety over the past century. Today’s protective equipment is designed to keep asbestos fibres out — not to be made from them. Understanding the difference is crucial for any employer or site manager overseeing maintenance work on older buildings.
Types of PPE Required for Asbestos Work
The right PPE depends on the nature and scale of the asbestos work being carried out. For most maintenance scenarios involving ACMs, the following equipment is required:
- Respiratory Protective Equipment (RPE) — face masks and respirators with an Assigned Protection Factor (APF) of at least 10 for low-risk work; higher-rated powered respirators for licensed work. RPE must be face-fit tested for each individual worker.
- Disposable protective overalls — single-use coveralls made from sealed, impermeable material that covers the entire body. These should be disposed of as asbestos waste after use and must never be taken home.
- Nitrile or latex gloves — to prevent skin contact with asbestos fibres when handling ACMs. Gloves must be replaced regularly.
- Eye protection — safety goggles or full-face shields to prevent fibre contact with the eyes, particularly during removal or clean-up operations.
- Footwear covers — waterproof boot covers prevent fibres from being tracked out of contaminated work areas into clean zones.
The contrast with asbestos fire suits is stark. Those garments were made of asbestos and released fibres during use. Modern disposable overalls are designed to trap fibres and are discarded safely — the exact opposite approach.
Proper Use and Maintenance of PPE
Providing PPE is only half the obligation. Employers must also ensure it is used correctly and maintained in good condition. Practical steps include:
- Inspecting all PPE before each use for signs of damage or deterioration
- Training workers on correct donning and doffing procedures to avoid self-contamination
- Storing PPE in clean, accessible areas away from contaminated zones
- Replacing damaged or worn PPE immediately — never allowing workers to use compromised equipment
- Disposing of single-use items as asbestos waste after each task
- Keeping records of PPE inspections and replacements
Engineering Controls: The First Line of Defence
PPE is important, but engineering controls should always come first. The hierarchy of controls requires employers to eliminate or reduce the risk at source before relying on personal protective equipment. This principle is central to HSE guidance on asbestos management.
For asbestos work, effective engineering controls include:
- Local exhaust ventilation (LEV) — captures asbestos fibres at the point of release before they become airborne
- Negative air pressure units — maintain negative pressure within the work area so that any air movement draws fibres inward rather than outward into clean areas
- Physical enclosures and barriers — isolate the work area from the rest of the building to contain fibre release
- Airlocks — create a buffer zone between contaminated and clean areas, preventing fibres from migrating
- HEPA-filtered vacuum cleaners — essential for clean-up; standard vacuum cleaners will simply redistribute fibres into the air
- Encapsulation — where removal is not immediately necessary, applying sealants to ACMs can prevent fibre release during low-risk maintenance
- Wet methods — dampening asbestos materials before disturbance reduces the amount of dust generated
All engineering controls must be regularly inspected and maintained. A ventilation system that has not been serviced provides a false sense of security — and that is more dangerous than having no system at all.
Employee Training: Building a Safety-Conscious Workforce
No system of controls works without informed, trained workers. The Control of Asbestos Regulations requires that anyone who is liable to disturb asbestos in the course of their work receives appropriate training. This is not a one-off exercise.
Asbestos Awareness Training
Asbestos awareness training is the baseline requirement for tradespeople and maintenance workers who may encounter ACMs. It should cover:
- What asbestos is, where it is likely to be found, and why it is dangerous
- How to recognise suspect materials and what to do if they are encountered unexpectedly
- The health effects of asbestos exposure, including mesothelioma, asbestosis and lung cancer
- The importance of not disturbing ACMs without proper controls in place
- How to report concerns and access the asbestos register
The HSE’s Asbestos Essentials guidance and the Asbestos Learning Package are useful training resources for employers. Training should be refreshed at least annually.
Safe Work Practices Training
For workers who carry out licensed or notifiable non-licensed asbestos work, more detailed training is required. This should include:
- Safe handling and removal techniques for specific ACM types
- Correct use of PPE, including face-fit testing for RPE
- Decontamination procedures — how to safely remove and dispose of protective overalls and equipment
- Emergency response procedures, including what to do if asbestos is unexpectedly disturbed
- Waste management and disposal requirements
Practical, hands-on training is far more effective than online-only delivery for these topics. Workers need to practise donning and doffing PPE correctly before they encounter real asbestos conditions.
Health Monitoring and Surveillance for Exposed Workers
Workers who carry out licensed asbestos work are entitled to health surveillance under the Control of Asbestos Regulations. This is not simply good practice — it is a legal requirement. The legacy of asbestos fire suits is a powerful illustration of what happens when health monitoring is absent: workers developed fatal diseases with no early warning and no opportunity for intervention.
Health surveillance for asbestos-exposed workers typically includes:
- An initial medical examination before commencing licensed asbestos work
- Regular follow-up examinations at intervals specified by an appointed doctor
- Maintenance of individual health records for a minimum of 40 years
- Access to records by the worker themselves upon request
Health surveillance does not prevent exposure — it monitors its effects. That is why it must sit alongside, not replace, robust engineering controls, PPE and training.
What to Do If Asbestos Is Discovered Unexpectedly
Despite the best planning, workers sometimes encounter suspect materials during routine maintenance. Knowing how to respond correctly can prevent a minor disturbance from becoming a serious exposure incident.
If asbestos is discovered unexpectedly during work, the correct steps are:
- Stop work immediately — do not continue disturbing the material
- Leave the area — all workers should evacuate the immediate vicinity calmly
- Prevent others from entering — cordon off the area and display appropriate warning signage
- Remove and bag contaminated clothing — seal it as asbestos waste; do not take it home
- Wash hands and face thoroughly — before eating, drinking or leaving the site
- Report the discovery — notify the site manager or dutyholder immediately
- Commission a survey and air testing — before work resumes, the area must be assessed by a qualified professional
The dutyholder must update the asbestos register and management plan to reflect the discovery. Work should not resume until a competent contractor has assessed the situation and confirmed it is safe to proceed.
Waste Disposal: Handling Asbestos Safely After Removal
Asbestos waste is classified as hazardous waste and must be disposed of in accordance with HSE guidance and relevant environmental regulations. Improper disposal is not just an environmental offence — it creates ongoing exposure risks for waste handlers and members of the public.
Key requirements for asbestos waste disposal include:
- Double-bagging all asbestos waste in heavy-duty, clearly labelled polythene bags
- Sealing bags securely and transporting them in appropriate containers
- Using only licensed waste carriers and licensed disposal sites
- Completing waste transfer documentation and retaining records
- Never mixing asbestos waste with general construction waste
The same principle applies to PPE. Disposable overalls, gloves and footwear covers used during asbestos work must be bagged and disposed of as asbestos waste — not placed in general bins or taken off site in personal vehicles.
Frequently Asked Questions
What were asbestos fire suits made from, and why were they dangerous?
Asbestos fire suits were typically woven from chrysotile (white asbestos) or amosite (brown asbestos) fibres. Both types are classified as carcinogenic. Every time the suits were worn, adjusted or stored, microscopic fibres were released into the air and inhaled by the wearer. Prolonged exposure caused mesothelioma, asbestosis and lung cancer — diseases that can take 20 to 40 years to develop after initial exposure.
Are asbestos fire suits still used today?
No. The UK banned the import, supply and use of all forms of asbestos in 1999. Asbestos fire suits have not been legally used in the UK since then. Modern firefighting and industrial protective clothing uses synthetic, heat-resistant materials that do not carry the same health risks.
What type of asbestos survey do I need before maintenance work?
For occupied premises where no structural work is planned, a management survey is the appropriate starting point. If you are planning refurbishment, renovation or structural alterations, a refurbishment survey is required. For buildings due to be demolished in whole or in part, a demolition survey must be completed before any work begins. All surveys should be carried out by a qualified surveyor working to HSG264 guidance.
What PPE is required for working near asbestos?
The minimum PPE for work involving ACMs includes respiratory protective equipment (RPE) that has been face-fit tested, disposable protective overalls, nitrile or latex gloves, eye protection and footwear covers. The specific level of RPE required depends on the type of work and the risk level involved. For licensed asbestos work, higher-rated powered respirators are typically required.
Who is responsible for managing asbestos in a commercial building?
Under the Control of Asbestos Regulations, the duty to manage asbestos falls on the dutyholder — typically the building owner, landlord or the person or organisation with control over the premises. In practice, this means commissioning surveys, maintaining an asbestos register and management plan, and ensuring that anyone likely to disturb ACMs is informed of their location and condition.
