How Environmental Asbestos Exposure Can Still Pose a Threat in Homes and Buildings

Asbestos refers to a group of six naturally occurring fibrous minerals that have been extensively used in commercial products throughout the 20th century. Its popularity stemmed from remarkable properties: resistance to heat, electricity, and chemical damage, along with sound absorptions and tensile strength. 

The material was particularly valued for its fireproofing capabilities, durability, and relatively low cost, making it an ideal component in insulation, roofing, floorings, and thousands of other products. Unfortunately, the same properties that made asbestos commercially valuable also made it extremely dangerous to human health when its microscopic fibers become airborne.

The Health Risks Associated with Asbestos Exposure

Asbestos exposure is associated with several serious and potentially fatal diseases, with symptoms often not appearing until 20-50 years after initial exposure. The most severe conditions include:

• Mesothelioma: A rare and aggressive cancer affecting the mesothelial lining of the lungs, abdomen, or heart. Nearly all cases are linked to asbestos exposure, with no known cure and poor survival rates.
• Lung cancer: Asbestos-related lung cancer resembles cancer caused by smoking but occurs specifically due to fiber inhalation damaging lung tissue over time.
• Asbestosis: A chronic, non-cancerous respiratory disease characterized by scarring of lung tissue, leading to shortness of breath, persistent cough, and permanent lung damage.
• Other conditions: Pleural plaques, pleural thickening, and pleural effusions can also develop from asbestos exposure, compromising respiratory function.

What makes asbestos particularly dangerous is that no amount of exposure is considered safe, and the fibers, once inhaled, can remain in the body indefinitely. If you are unlawfully exposed to asbestos contact a Massachusetts mesothelioma lawyer for assistance.

Where Asbestos May Still Be Found in Today’s Home and Buildings

Common Residential Sources of Asbestos

Despite significant reduction in new asbestos use, millions of American homes (particularly those built before 1980) still contain asbestos materials. Common sources include:

• Insulation: Pipe insulation, loose-fill attic insulation, and insulation around boilers and furnaces often contain asbestos.
• Flooring: Vinyl floor tiles, sheet vinyl flooring, and the adhesives used to install them frequently contained asbestos until the 1980s.
• Roofing materials: Asbestos was commonly used in roofing shingles, felt, and tar for waterproofing.
• Textured surfaces: Popcorn ceilings, textured paints, and joint compounds often incorporated asbestos for fire resistance and texture.
• Other materials: Cement siding, windows caulking, fireplace components, electrical insulation, and even some applications may contain asbestos.

Undisturbed and intact asbestos-containing materials generally don’t pose an immediate health risk. However, as these materials age, deteriorate, or become damaged, they can release dangerous fibers into the indoor environment.

Commercial and Public Buildings with Asbestos Concerns

Asbestos concerns extend beyond residences to many public and commercial structures:

• Schools: It is estimated that asbestos is present in most of America’s schools built before 1980, potentially affecting millions of children and staff.
• Office buildings: Older commercial properties often contain asbestos in ceiling tiles, insulation, flooring and fireproofing.
• Industrial facilities: Manufacturing plants, power stations, and refineries extensively used asbestos for its heat-resistance properties.
• Public buildings: Hospitals, libraries, courthouses, and government buildings constructed before the 1980s frequently contain asbestos materials.

Regular occupants of these buildings may face long-term, low-level exposure – a particular concern given the cumulative nature of asbestos-related health risks.

How Asbestos Becomes an Environmental Threat

The Role of Aging Infrastructure and Renovations

Asbestos-containing materials (ACMs) become hazardous when they release fibers into the air. This commonly occurs during:

• Home renovations: DIY projects involving drilling, sawing, sanding, or removing old materials can disturb previously stable asbestos, creating dangerous dust.
• Normal wear and tear: As buildings age, materials deteriorate naturally through vibration, water damage, friction, or physical impact, potentially releasing fibers.
• Improper maintenance: Activities like sweeping damaged asbestos floors or removing deteriorating pipe insulation without proper precautions can create significant exposure risks.

The danger is particularly acute because asbestos fibers are microscopic and invisible to the naked eye. Homeowners often unknowingly create hazardous conditions while attempting standard home improvements or repairs.

Environmental Contamination Through Natural Disasters or Demolition

Beyond everyday activities, larger-scale events can release asbestos into communities:

• Natural disasters: Hurricanes, floods, tornadoes, and wildfires can damage thousands of structures simultaneously, releasing asbestos into the air and water.
• Building demolition: Improperly managed demolition of older structures can spread asbestos dust throughout neighborhoods.
• Landfill contamination: When asbestos materials are improperly disposed of, they can contaminate soil and potentially groundwater.

The aftermath of disasters presents a particularly high-risk period, as emergency cleanup often occurs without proper asbestos safety protocols, potentially exposing both disaster victims and response workers.

Identifying and Managing Asbestos in Your Property

Warning Signs and When to Get an Inspection

Visual identification of asbestos is difficult, but certain warning signs warrant professional inspection:

• Building materials from pre-1980 construction
• Deteriorating insulation, particularly around pipes or boilers
• Crumbling ceiling textures or “popcorn” ceilings
• Damages floor tiles, especially 9-inch vinyl tiles

Professional asbestos inspectors use specialized equipment and laboratory testing to accurately identify asbestos-containing materials. The EPA recommends inspection before any renovation project in older homes.

Safe Removal and Abatement Procedures

When asbestos is identified, proper management is critical:

• Encapsulation: In some cases, sealing intact asbestos materials prevents fiber release without removal.
• Enclosure: Creating barriers that separate ACMs from building occupants can be effective for certain situations.
• Removal: When necessary, only licensed asbestos abatement contractors should remove materials, following strict protocols including contaminants areas with negative air pressure, proper PPE and regulated disposal procedures.

DIY removal is strongly discouraged and often illegal under local regulations, as improper handling creates greater exposure risk than leaving materials undisturbed.

Preventing Exposure and Protecting Your Health

Practical steps to minimize asbestos exposure include:

• Testing suspected materials before beginning any renovation project.
• Hiring qualified professionals for repairs involving potential asbestos materials.
• Never drilling, sanding scraping or disturbing suspected asbestos materials.
• Keeping potentially asbestos-containing materials in good repair.
• Monitoring known asbestos materials for signs of damage or deterioration.

While asbestos presents significant health risks, these risks are manageable through proper identification, professional assessment, and appropriate abatement when necessary. With careful attention to where asbestos may lurk in our everyday environments, we can minimize its impact on current and future generations.
