Asbestos might sound like a problem from the past, but it’s still a hidden danger in many older buildings and work environments today. Exposure to asbestos fibers can lead to serious health conditions like asbestosis, lung cancer, and mesothelioma — diseases that often take years to appear. Whether you’re a contractor, property owner, or employer, understanding how to prevent asbestos exposure is crucial.
This article provides a complete guide to asbestos exposure prevention, explaining the risks, where asbestos is found, and the safest practices for homeowners and professionals alike.
What to Know
Asbestos refers to a group of naturally occurring minerals known for their strength and resistance to heat and corrosion. These qualities made asbestos a common ingredient in construction materials, insulation, cement, and brake linings for much of the 20th century.
While the use of asbestos is now restricted or banned in many countries, including the UK and EU, millions of homes and buildings still contain asbestos materials. According to the World Health Organization (WHO), more than 125 million people worldwide are exposed to asbestos in the workplace each year.
What Increases Your Risk
You’re at a higher risk of asbestos exposure if you:
- Work in construction, demolition, or shipbuilding
- Handle insulation or roofing materials in older properties
- Live or work in buildings built before 2000 (in the UK)
- Perform vehicle brake or clutch repairs
- Disturb soil or rock in areas with naturally occurring asbestos
Long-term or repeated exposure increases the likelihood of developing asbestos-related diseases, especially among smokers or those with preexisting lung conditions.
Exposure
Asbestos exposure occurs when materials containing asbestos are disturbed, releasing tiny fibers into the air. Once inhaled, these fibers can lodge in the lungs and remain there permanently.
After Exposure
If you believe you’ve been exposed:
- Leave the contaminated area immediately.
- Avoid brushing or shaking off clothing.
- Wash thoroughly and change clothes.
- Notify your employer or safety manager if exposure happened at work.
- Seek medical evaluation if symptoms such as shortness of breath or persistent cough appear.
When Care Is Needed
Medical attention is needed if:
- You’ve had significant or repeated exposure.
- You experience breathing difficulties, chest pain, or coughing that doesn’t go away.
- Your doctor recommends imaging tests or lung function screening.
Early diagnosis can help manage symptoms and monitor potential long-term health effects.
Prevention Tips
Workers
- Follow workplace asbestos control procedures strictly.
- Always wear approved P2 or P3 respirators and disposable protective clothing.
- Avoid eating or drinking in areas with possible asbestos exposure.
- Participate in asbestos awareness training programs.
- Never use power tools or drills on materials that might contain asbestos.
Older Homes
- Don’t disturb suspected asbestos materials like ceiling tiles, pipe insulation, or floor coverings.
- Hire a certified asbestos surveyor before renovation or demolition.
- Seal or encapsulate asbestos-containing materials if they are in good condition.
- Never sand, scrape, or pressure wash asbestos cement sheets.
Areas with Natural Asbestos Deposits
- Avoid digging or disturbing soil unnecessarily.
- Wet the ground before working outdoors to reduce dust.
- Wear a mask when working around exposed rock or soil.
- Keep children and pets away from disturbed areas.
What Are the Hazards of Asbestos?
Asbestos exposure can lead to severe respiratory diseases:
- Asbestosis (lung scarring)
- Mesothelioma (a rare cancer of the lung lining)
- Lung cancer
- Pleural thickening
According to the HSE (Health and Safety Executive, UK), asbestos exposure still causes around 5,000 deaths each year in the UK — more than road traffic accidents.
Where Is Asbestos Found in Homes and Residential Buildings?
Asbestos can be found in:
- Pipe and boiler insulation
- Ceiling and floor tiles
- Roof shingles and siding
- Sprayed coatings and textured paints
- Cement sheets and panels
- Older HVAC duct insulation
Buildings built before the year 2000 are the most likely to contain these materials.
Protecting Workers
Employers must comply with the Control of Asbestos Regulations 2012 (UK) or equivalent laws in other countries. Key measures include:
- Conducting asbestos risk assessments
- Providing proper PPE (Personal Protective Equipment)
- Maintaining air monitoring and medical surveillance
- Displaying warning signs in contaminated areas
- Ensuring only licensed professionals handle removal tasks
Other Safety and Health Hazards
Besides asbestos, workers in older buildings may face other hazards such as:
- Lead paint exposure
- Mold and dust inhalation
- Confined space risks
- Electrical hazards during renovation
A comprehensive safety plan should address all these potential risks.

Assistance for Employers
Employers can seek help from:
- HSE’s Asbestos Essentials guidance documents
- Local environmental health authorities
- Certified asbestos removal contractors
- Professional occupational safety consultants
How to Identify Materials That May Contain Asbestos
Visual identification alone is unreliable. Instead:
- Hire a certified asbestos inspector.
- Collect samples safely (never DIY).
- Get materials analyzed in an accredited laboratory.
What to Do If You Have Asbestos in Your Home
If asbestos is in good condition and not disturbed, it’s usually safer to leave it alone.
- Mark the area and inform anyone doing maintenance.
- Schedule professional monitoring.
- If damaged, hire a licensed asbestos abatement contractor.
Asbestos Do’s and Don’ts for the Homeowner
Do:
- Keep asbestos-containing materials in good repair.
- Use qualified professionals for inspections.
- Wet surfaces before minor maintenance.
Don’t:
- Drill, saw, or sand asbestos materials.
- Use household vacuum cleaners to remove asbestos dust.
- Attempt DIY asbestos removal.
If You Have an Asbestos Problem
- Limit access to the affected area.
- Contact your local environmental health authority.
- Get quotes from licensed asbestos removal firms.
- Ensure safe disposal following local regulations.
Asbestos Professionals: Who Are They and What Can They Do?
Asbestos professionals include:
- Inspectors/Surveyors: Identify and assess asbestos materials.
- Contractors/Abatement Specialists: Safely remove or encapsulate asbestos.
Both must be accredited under recognized asbestos management schemes.
Before You Hire an Asbestos Professional
- Verify certification and insurance.
- Request references and written estimates.
- Ensure compliance with national asbestos regulations.
If You Hire an Asbestos Professional Inspector
Inspectors should:
- Perform thorough visual checks.
- Take samples safely.
- Provide a written report detailing asbestos locations, conditions, and recommendations.
If You Hire an Asbestos Professional Contractor
Contractors should:
- Follow strict containment procedures.
- Use HEPA-filtered vacuums.
- Dispose of asbestos waste at approved facilities.
- Provide post-removal air testing results.
Brake and Clutch Repairs
Vehicle mechanics can still encounter asbestos in older brake pads or clutches.
To reduce risk:
- Use low-pressure spray equipment to wet parts before handling.
- Avoid compressed air or dry brushing.
- Use designated asbestos service areas with proper ventilation.
Conclusion
Preventing asbestos exposure starts with awareness. Whether at work, home, or during renovation, knowing where asbestos may be and how to handle it safely can save lives. By following these prevention tips, hiring qualified professionals, and adhering to regulations, you can significantly reduce the risk of exposure — protecting yourself, your workers, and your community.
