WhiskersWhat is Asbestos?
Asbestos is a mineral known for its heat- and fire-resistant properties, commonly used in building materials such as flooring, ceilings, roofs, and automotive parts. The connection between Asbestos exposure and health risks only became evident in the 1950s.
Asbestos is banned in 55 countries, but it is still imported and used in the United States, albeit at lower levels than in the past.
How are People Exposed to Asbestos?
Exposure to Asbestos typically occurs in two main ways: by inhaling the toxic particles or by accidentally swallowing (ingesting) them. These two types of exposure are associated with different types of Asbestos. All forms of Asbestos exposure are dangerous.
Inhalation Exposure
When tiny bits of Asbestos become airborne, they can be inhaled directly into the lungs of those nearby. Types of Asbestos with sharp fibers that can be easily inhaled include:
- Actinolite Asbestos: Used in products like cement, insulation, paint, and drywall.
- Amosite Asbestos (brown Asbestos): Commonly used in cement, insulation, roofing, and other construction materials.
- Anthophyllite Asbestos: A less common type found in cement and insulation materials.
- Crocidolite Asbestos (blue Asbestos): The most dangerous type, with fine fibers that are easy to inhale. It was used in cement, tiles, and insulation.
- Tremolite Asbestos: Heat-resistant and previously used in products like paint, sealants, insulation, roofing, and plumbing materials. It is no longer mined.
Ingestion Exposure
Asbestos fibers can also enter the mouth and be accidentally swallowed. Chrysotile Asbestos (white Asbestos) can be inhaled but is most commonly associated with ingestion.
While some companies argue that chrysotile Asbestos mined today is safe when used in certain products, health professionals assert that all forms of Asbestos are carcinogenic, and no level of exposure is safe.
How Does Asbestos Cause Cancer?
If Asbestos is inhaled or swallowed, its microscopic fibers can become lodged in the lungs and remain there for years. Over time, they cause inflammation and scarring, potentially leading to cancer.
Most people do not exhibit symptoms immediately after Asbestos exposure. Early signs may include vague symptoms such as coughing or shortness of breath. These symptoms are often mistaken for less serious conditions, leading many to delay seeking medical attention.
Diseases caused by Asbestos exposure include:
- Asbestosis
- Lung cancer
- Mesothelioma
- Pleural disease
Cancer or disease resulting from Asbestos exposure can take 20 to 50 years to develop. When symptoms do appear, they may include:
- Anemia or a high white blood cell count
- Difficulty breathing, shortness of breath (dyspnea), coughing up blood, or persistent cough
- Fatigue
- Fever and loss of appetite
- Insomnia and night sweats
- Pain in the chest or lungs
- Unexplained weight loss
How to Get Rid of Asbestos
There are approximately 30 million homes and buildings in the U.S. that contain Asbestos. Understanding the causes, risk factors, and prevention of mesothelioma is crucial to living safely with Asbestos.
In some cases, disturbing Asbestos-containing materials to remove them is more dangerous than leaving them undisturbed. Disturbance releases fibers into the air, increasing the risk of inhalation. Therefore, it is often safer to leave Asbestos-containing materials alone.
If Asbestos-containing materials are in good condition, it is generally best not to disturb them. However, if Asbestos poses a health threat, it should either be repaired or removed. Only a licensed professional can test for Asbestos and determine if removal is necessary and safe.
If you suspect your home contains Asbestos, contact a licensed Asbestos removal contractor for an inspection and testing. Based on the results, they will recommend whether the Asbestos-containing material should be removed.
Asbestos Repair
Repairing Asbestos involves either encapsulation or enclosure. Encapsulation entails applying a sealant to Asbestos materials to prevent fiber release. Enclosure involves covering the Asbestos with airtight materials to contain the fibers and prevent their release.
Asbestos Removal
The U.S. federal government enforces strict guidelines for Asbestos removal. Licensed professionals undergo training and follow specific procedures, including:
- Sealing off the work area with plastic sheeting to prevent fibers from spreading.
- Using HEPA air filters and clean air exhaust ducts to purify the air inside and outside the work area.
- Wearing protective suits and respirators while removing Asbestos.
- Inspecting the area throughout the process to ensure complete removal.
- Placing Asbestos materials in labeled, double plastic bags.
After removal, the remediation team thoroughly cleans the area with HEPA vacuums and wipes it down. Asbestos materials are sealed and taken to an approved disposal site, labeled as toxic, hazardous waste to ensure safe handling. Proper disposal prevents further health hazards and ensures the Asbestos materials are not disturbed.
