The Complete Guide to Asbestos: Types, Properties, Locations, and Health Risks in London

Introduction

Asbestos was once considered a miracle construction material and was widely used throughout the 19th and 20th centuries in homes, offices, factories, and public buildings. Its strength, heat resistance, and affordability made it incredibly popular.
However, these same properties make asbestos dangerous when fibres become airborne. Understanding asbestos types, uses, locations, and health risks is essential for homeowners, landlords, builders, and anyone involved in renovation or demolition.

What Is Asbestos?

Asbestos is a group of naturally occurring silicate minerals made up of millions of microscopic, needle-like fibres. These fibres formed over millions of years due to heat, pressure, and mineral reactions in rocks like serpentinite and amphibolite.

Key Characteristics of Asbestos Fibres

• Extremely thin (often invisible to the naked eye)
• Strong and flexible
• Highly resistant to heat and fire
• Chemically stable
• Non-biodegradable (do not rot or decompose)

Key Risk: Asbestos fibres easily become airborne and can be inhaled, remaining in the lungs for decades.

Why Asbestos Was So Popular (19th–20th Century)

Asbestos became widely used because it offered:

• Excellent heat, fire, and electrical insulation
• High tensile strength while remaining lightweight
• Chemical and water resistance
• Low production cost
• Easy integration into cement, insulation boards, textiles, and numerous building products

How Asbestos Forms Naturally

Asbestos is not man-made; it forms inside the Earth’s crust due to heat, pressure, and mineral reactions.

Parent Rock Groups

Serpentine Rocks

• Produce Chrysotile asbestos (white asbestos)
• Most common asbestos type worldwide

Amphibole Rocks

• Produce:
  • Amosite (brown)
  • Crocidolite (blue)
  • Tremolite
  • Actinolite
  • Anthophyllite

Main Families and Types of Asbestos

Serpentine Group

Chrysotile (White Asbestos)

• Accounts for 90–95% of global asbestos use
• Soft, curly fibres
• Highly heat-resistant
• Easily woven or mixed with cement

Common Uses

• Roofing sheets
• Wall/ceiling panels
• Floor tiles
• Textured coatings (e.g., Artex)
• Boiler insulation
• Brake linings

Amphibole Group

General Features

• Straight, needle-like fibres
• Brittle and extremely hazardous
• Remain in lungs for decades

Types of Amphibole Asbestos

• Amosite (Brown)
• Crocidolite (Blue)
• Tremolite
• Actinolite
• Anthophyllite

Health Risk: Amphibole asbestos is strongly linked to mesothelioma, lung cancer, and asbestosis.

Common Building Products Containing Asbestos

More than 3,000 products historically contained asbestos.

Where Asbestos Is Found in London Buildings

Buildings constructed before 2000 may contain asbestos. Here are the most common locations:

Sprayed Coatings (Limpet Asbestos)

• Found on steelwork, car parks, ceilings, lift shafts
• Up to 85% asbestos (blue or brown)
• Extremely friable and high-risk

Pipe & Boiler Insulation (Lagging)

• Used until the 1980s
• Soft, crumbly with age
• One of the most hazardous ACMs

Asbestos Insulating Board (AIB)

• Soffits, fire doors, partitions, risers, ceiling tiles
• Contains 10–40% amosite
• Breaks easily → high fibre release risk

Asbestos Cement Products

• Roof sheets, gutters, chimneys, garages, water tanks
• Lower risk but dangerous when cut, drilled, or weather-damaged

Flooring Materials

• Vinyl/thermoplastic tiles
• Bitumen adhesives
• Old linoleum backing

Textured Coatings (Artex)

• Decorative ceilings/walls pre-1990s
• Low risk when intact, but dangerous when scraped or sanded

Why Asbestos Is Dangerous

Asbestos becomes dangerous when fibres are released into the air.

Causes of Fibre Release

• Drilling, cutting, sanding
• Renovation or demolition
• Damage or natural deterioration

Health Risks

Even small exposure can be dangerous.

How Asbestos Became a Health Crisis

• Strong industry lobbying delayed bans
• Long latency (20–40 years) hides symptoms
• Lack of awareness in construction trades
• UK finally banned asbestos in 1999

Prevention and Safety (Legal Under CAR 2012)

Managing asbestos safely is a legal requirement under the Control of Asbestos Regulations 2012.

Never Attempt DIY Removal

Why DIY Removal Is Dangerous

• Releases millions of invisible fibres
• Spreads contamination quickly
• Illegal for many asbestos types (e.g., lagging, AIB)

Conduct Professional Asbestos Surveys

Two main UK survey types:

Management Survey

• For occupied buildings
• Identifies low-risk ACMs

Refurbishment & Demolition (R&D) Survey

• Required before renovations, rewiring, plumbing, demolition
• Finds hidden asbestos

Hire Licensed Contractors

Essential Accreditation

• HSE Licensed Asbestos Removal Contractors
• UKAS Accredited Labs
• BOHS P402/P405 surveyors

Why Licensing Matters

• Correct equipment
• Safe removal procedures
• Air monitoring & clearance
• Full legal documentation

Proper Containment, PPE & Disposal

Containment Measures

• Plastic sheeting
• Negative pressure units
• Airlocks & decontamination units

PPE Requirements

• Type 5/6 disposable suits
• FFP3 respirators
• Gloves, overshoes

Disposal

• Double-bagged, UN-approved asbestos bags
• Licensed waste carriers only
• Disposal at approved hazardous waste sites

Illegal disposal is a criminal offence.

Keep Documentation

Documents to Maintain

• Management surveys
• R&D surveys
• UKAS analysis certificates
• RAMS
• Air monitoring reports
• Waste transfer notes
• Asbestos management plans

Missing documentation → fines and legal consequences.

Frequently Asked Questions (FAQs)

What year was asbestos banned in the UK?

Asbestos was fully banned in 1999.

Did all pre-2000 buildings contain asbestos?

No, but many did—especially between the 1950s–1980s. Only a survey can confirm.

Is asbestos safe if it’s not disturbed?

Generally yes — intact asbestos poses minimal risk.
Risk begins when materials are damaged, cut, drilled, or broken.

Which type of asbestos survey do I need?

• Management Survey → for routine safety
• R&D Survey → before renovations or demolition

How can I confirm exposure or presence of asbestos?

Only UKAS-accredited laboratory testing can confirm asbestos. Visual identification is impossible.

Who is responsible for asbestos in a building?

The Duty Holder under CAR 2012:

• Landlord
• Property Manager
• Freeholder
• Employer (commercial spaces)

Can I remove asbestos myself?

No. Most asbestos removal is hazardous and often illegal to perform without licensing.

What should I do if I disturb asbestos accidentally?

• Stop work immediately
• Evacuate and isolate the area
• Do NOT sweep or vacuum
• Contact a licensed asbestos contractor
• Arrange air testing

How long does asbestos remain hazardous?

Indefinitely. Asbestos fibres do not break down naturally.
