How to Remove Asbestos from Your Air?

Dealing with asbestos, especially on job sites, is heavily regulated due to its significant health risks. These regulations are in place to ensure that only trained professionals handle asbestos to prevent exposure.

For non-professionals or the general public, direct interaction with or attempts to remove asbestos is strongly discouraged due to the high risk of releasing asbestos fibers into the air, which can lead to serious health issues upon inhalation.

But clearly there are times when encountering asbestos may be unavoidable.

You may suspect or have confirmed the presence of asbestos but cannot immediately access professional remediation services.

This can occur in varied ways:

After Disturbance: Discovering that asbestos-containing materials have been accidentally disturbed, releasing fibers into the air.

During Renovations: During DIY home renovations or in workspaces where renovations uncover previously undisturbed asbestos.

In Rented Spaces: Tenants in older buildings might suspect asbestos but have landlords who are unresponsive or slow to take action.

In Workplaces: Employees might become aware of asbestos in their workplace but find that their employer is delaying professional assessment or remediation.

In Waiting Periods: When professional asbestos removal is scheduled but there’s a waiting period before the work begins.

In these scenarios, the primary concern is reducing immediate asbestos exposure until professional help can be secured.

Temporary Measures for Reducing Asbestos in the Air

HEPA Air Purifiers

While HEPA air purifiers cannot eliminate the source of asbestos, they can help reduce airborne asbestos fibers. Its importance to choose air purifiers with HEPA filters rated to capture particles as small as 0.3 microns. For asbestos, the denser the filter, the better. We recommend air purifiers that can use H13 and H14 filters.

Usage: Placing them near the disturbed area and run them continuously.
Selection:

Seal Off Area

Seal off the area where asbestos disturbance occurred to prevent the spread of fibers to other parts of the building or home.
The Goal is to isolate the threat: Use plastic sheeting and tape to seal the area.

Ventilation

Avoid using HVAC systems that might circulate asbestos fibers throughout the space.

Personal Safety

Consider wearing personal protective equipment (PPE), such as P100 respirators and disposable coveralls, when near the affected area to minimize personal exposure.

Preventing Home Contamination from Workplace Asbestos

When asbestos is present at your job, it’s natural to worry about accidentally bringing it home, potentially exposing your family to its dangers.

Here are targeted strategies to prevent this:

1. Dedicated Work Attire: Maintain a set of clothing exclusively for work, including footwear. Changing out of these clothes before leaving work can significantly reduce the risk of carrying asbestos fibers home.
2. Secure Storage: Use on-site lockers or airtight bags to store your work attire after changing. This containment helps prevent any loose fibers from escaping.
3. Home Entry Routine: Establish a routine at home where you immediately place any potentially contaminated items in a designated area for cleaning or disposal. This might include items like your work bag or personal protective gear that you can’t leave at work.
4. Separate Laundry: Wash work clothes separately from the household laundry. Consider using disposable coveralls that can be discarded after use to eliminate the need for laundering potentially contaminated work clothes.
5. Vehicle Care: If you must transport potentially contaminated items, place them in a sealed container or bag in the trunk. Regularly clean your vehicle’s interior, focusing on areas that might come into contact with work-related items.
6. Communication with Household Members: Inform your family about the importance of these measures and why maintaining this separation is crucial for everyone’s health.

Identifying Potential Asbestos Hazards in Your Environment

While asbestos itself cannot be seen, smelled, or felt directly, certain indicators can signal its presence:

1. Building Age: Buildings constructed or significantly renovated before the late 1970s are more likely to contain asbestos materials. If your workplace or home falls into this category, it’s wise to be cautious.
2. Common Asbestos-Containing Materials: Familiarize yourself with the types of materials that commonly contained asbestos, such as popcorn ceilings, vinyl floor tiles, insulation around pipes, and certain types of shingles. Recognizing these materials can serve as a warning to take extra precautions.
3. Material Condition: Pay attention to the condition of older building materials. If you notice wear, damage, or signs of disturbance in materials known to potentially contain asbestos, this could indicate a higher risk of fiber release.
4. Review Historical Records: If possible, consult any available construction records, renovation logs, or material safety data sheets for your building. These documents can provide insights into the materials used and whether they might contain asbestos.

Key Takeaway: While direct detection of asbestos through sight, smell, or feel is not possible due to the microscopic nature of asbestos fibers, understanding the types of materials that may contain asbestos, along with historical building information, can guide you in identifying potential risks. Professional assessment remains the most reliable approach to confirm the presence of asbestos and determine the necessary safety measures.

Historical Use and Initial Discovery of Hazards:

1. Ancient Use: Historical records indicate that asbestos was known and used by ancient civilizations, like the Greeks and Romans, for its fire-resistant properties. They used it in lamp wicks, clothing, and building materials. However, there are also early accounts suggesting that they noticed health problems among those who worked with the material.
2. Industrial Revolution: The use of asbestos materials expanded significantly during the Industrial Revolution. It became a popular material for insulation, fireproofing, and other industrial applications due to its durability and resistance to heat and chemicals.
3. Early Health Concerns: The first documented health concerns related to asbestos exposure date back to the late 19th and early 20th centuries. Factory inspectors and physicians began to notice a higher incidence of lung problems and early deaths among workers in asbestos mining and manufacturing industries.
4. Medical Research and Studies: Throughout the 20th century, medical research increasingly linked asbestos exposure to various lung conditions, including asbestosis (a fibrotic lung disease caused by asbestos fibers) and later mesothelioma (a rare form of cancer almost exclusively associated with asbestos exposure). Studies observed workers in industries such as shipbuilding, construction, and textile manufacturing, where asbestos use was prevalent.
5. Public Awareness and Regulation: By the mid to late 20th century, the evidence of asbestos-related health risks became more widely recognized, leading to public awareness campaigns, regulatory changes, and eventually bans or strict controls on asbestos use in many countries.

How Long Does Asbestos Stay Airborne?

“The duration asbestos fibers remain airborne depends on factors like fiber size and disturbance method – smaller fibers under 5 microns can stay suspended for weeks, while larger fibers settle in hours. More aggressive mechanical release causes longer airborne times than low-impact disturbance, but there are no exact rules for how long asbestos stays airborne after release.”

Airborne Duration Table

Airborne Duration of Different Types of Asbestos

Chrysotile Asbestos

Common Sources: Chrysotile, also known as white asbestos, is the most common form of asbestos found in buildings. It is frequently used in roofing materials, floor and ceiling tiles, insulation, and various textiles. Chrysotile fibers are also found in automotive parts like gaskets and brake linings due to their resistance to heat.

Airborne Duration:

• Large Fibers (>5 Microns): These fibers tend to settle within hours in calm indoor environments and within minutes in outdoor or windy conditions.
• Small Fibers (<5 Microns): Smaller chrysotile fibers can remain airborne for up to a few days in calm indoor air, and for a few hours outdoors. In constantly disturbed air, such as during ongoing construction activities, these fibers can stay suspended for up to several weeks.

Amphibole Asbestos

Common Sources: Amphibole asbestos includes types such as amosite (brown asbestos) and crocidolite (blue asbestos). These fibers are typically found in high-temperature applications such as insulation for pipes and boilers, and in some cement products. Amphibole fibers are known for their needle-like shape.

Airborne Duration:

• Large Fibers (>5 Microns): Similar to chrysotile, larger amphibole fibers will settle within hours in calm air and within minutes when exposed to windy conditions outdoors.
• Small Fibers (<5 Microns): The thinner and more durable nature of amphibole fibers means they can remain airborne for several days in calm air, and for a few hours in windy conditions. In environments where the air is constantly disturbed, these fibers can remain suspended for weeks or even indefinitely in extreme cases.

Sanded Asbestos

Common Sources: Sanded asbestos refers to the dust created when asbestos-containing materials like flooring, ceiling tiles, joint compounds, and plaster are mechanically disturbed through sanding. This process is particularly risky as it aggressively releases a mixture of fiber sizes into the air.

Airborne Duration:

• Mixed Fiber Sizes: The act of sanding can release a significant concentration of asbestos fibers into the air. In calm indoor environments, this dense concentration of fibers can result in a significant airborne presence for more than 48 hours. Outdoors or in windy conditions, the fibers will disperse more rapidly but still start at a high initial concentration. In areas with constant disturbance, elevated levels of airborne fibers can persist for weeks, especially in confined spaces.

Other Types of Asbestos:

1. Tremolite Asbestos:
   • Common Sources: Not used commercially on its own, tremolite asbestos can be found as a contaminant in chrysotile asbestos, vermiculite insulation, and talc powders.
   • Airborne Duration: Similar to other forms of asbestos, tremolite fibers can remain airborne for extended periods, especially the finer fibers. The specific duration would depend on the environment and the form in which the tremolite is present (e.g., within chrysotile or in contaminated vermiculite).
2. Actinolite Asbestos:
   • Common Sources: Less commonly used, actinolite asbestos can be found in some insulation materials, paints, and sealants.
   • Airborne Duration: Actinolite fibers, due to their brittle nature, can easily become airborne and may stay suspended for prolonged periods similar to other amphibole types.
3. Anthophyllite Asbestos:
   • Common Sources: Rarely used in commercial products, anthophyllite can be found in some composite flooring and insulation materials.
   • Airborne Duration: Given its rarity and limited use, specific airborne duration data is less available, but it would likely mirror other amphibole asbestos fibers in behavior.

Additional Situations of Concern:

1. Demolition of Asbestos-Containing Structures:
   • Large-scale demolition can release significant quantities of asbestos fibers into the air, especially if proper abatement procedures are not followed. The duration and concentration of airborne fibers would be highly variable, depending on the methods used and the types of asbestos-containing materials present.
2. Natural Weathering and Degradation:
   • Asbestos-containing materials that are exposed to the elements over time can degrade, releasing fibers into the air. This can occur in older buildings with exterior asbestos products or in natural deposits. The duration of fibers remaining airborne would depend on environmental conditions.
3. Fire and High-Temperature Exposure:
   • Exposure to high temperatures or fire can cause asbestos-containing materials to break down, releasing fibers. The impact of such situations on airborne duration is complex and would vary based on the intensity of the heat and the type of asbestos material involved.

Situations with Increased Danger and Risk

1. DIY Renovations in Older Homes:
   • Risk Level: High
   • Context: Homes built before the 1980s may contain asbestos in various materials. DIY renovations, like sanding, drilling, or cutting into walls, ceilings, or floors, can unknowingly disturb these materials, releasing fibers. The lack of professional control and containment can lead to prolonged exposure.
2. Accidental Damage to Asbestos-Containing Materials:
   • Risk Level: Moderate to High
   • Context: Accidental disturbances, such as damaging insulation, ceiling tiles, or other asbestos-containing materials, can release fibers. The risk is particularly high if the area is not promptly and properly contained and cleaned.
3. Professional Asbestos Abatement:
   • Risk Level: Low to Moderate
   • Context: When conducted by licensed professionals, asbestos removal is performed under strict regulations and safety measures, minimizing the release of fibers and exposure. However, some risk remains, especially if safety protocols are not adhered to.
4. Natural Disasters or Building Deterioration:
   • Risk Level: High
   • Context: Events like earthquakes, floods, or significant wear and tear can disturb asbestos-containing materials in structures, leading to unexpected exposure. The extent of fiber release depends on the condition of the materials and the nature of the disaster.
5. Occupational Exposure in Construction, Demolition, and Maintenance:
   • Risk Level: Very High
   • Context: Workers in these industries face the highest risk, especially when working in older buildings where asbestos is more common. Without proper precautions, these activities can result in significant asbestos fiber release and prolonged exposure.

Risk Mitigation Strategies

For each of these scenarios, specific strategies can be employed to mitigate the risks:

• DIY Projects: Before beginning any renovation project in an older home, have the materials assessed for asbestos. If asbestos is present, consider hiring a professional for removal.
• Accidental Damage: If asbestos-containing materials are accidentally damaged, isolate the area, avoid further disturbance, and consult with an asbestos abatement professional.
• Professional Abatement: Ensure the abatement company is licensed and follows all safety regulations. Stay out of the area until the work is complete and clearance air testing confirms it’s safe to return.
• Natural Disasters: After a disaster, have a professional assess the damage for potential asbestos exposure risks before starting clean-up or renovation efforts.
• Occupational Safety: Workers should use appropriate PPE, follow safety protocols, and participate in asbestos awareness and safety training programs.
