What is Asbestos?

Understanding Asbestos: Risks, Regulations, and Safe Removal in Oregon

Asbestos is a serious health hazard. It was once a common building material, but today, we know it can cause life-threatening diseases. Many homes and buildings in Oregon still contain asbestos, making it a major concern for homeowners, contractors, and business owners.

If you are planning a renovation, demolition, or repair project, it’s important to understand asbestos risks. Oregon has strict laws for asbestos abatement, removal, and disposal to protect public health. Knowing how to handle asbestos safely can prevent exposure and keep your property in compliance with state regulations.

This guide will explain what asbestos is, why it’s dangerous, where it’s found, and how to deal with it properly under Oregon law.

What is Asbestos?

Asbestos is a naturally occurring mineral that was widely used in construction before its dangers became known. It is made up of tiny fibers that are strong, flexible, and resistant to heat and chemicals. Because of these properties, asbestos was added to many building materials to improve durability and fire resistance.

For decades, asbestos was used in:

• Insulation (attics, walls, and around pipes)
• Flooring (vinyl tiles, adhesives, and linoleum backing)
• Ceiling materials (popcorn ceilings and textured coatings)
• Roofing and siding (asbestos cement shingles and tar paper)
• Drywall and joint compounds
• Furnace and boiler insulation

If your home or business was built before 2004, there is a chance it contains asbestos. Buildings from the mid-20th century are even more likely to have asbestos materials.

Why is Asbestos Dangerous?

Asbestos is most dangerous when disturbed. Cutting, drilling, sanding, or removing asbestos materials can release tiny fibers into the air. These fibers are too small to see, but when inhaled, they can get stuck in the lungs.

Over time, asbestos exposure can cause serious illnesses, including:

• Mesothelioma – A rare but aggressive cancer that affects the lining of the lungs and abdomen.
• Asbestosis – A lung disease that causes scarring and breathing problems.
• Lung Cancer – People who work with asbestos over time have a higher risk of developing lung cancer.

These diseases take years—sometimes decades—to appear. That’s why asbestos exposure is so dangerous. People may breathe in asbestos fibers without knowing it and won’t see health effects until many years later.

The best way to stay safe is to never disturb asbestos-containing materials unless necessary. If asbestos removal is required, it must be done carefully by licensed professionals.
