Which term best describes a material that is potentially harmful and has a crumbly texture, often associated with older buildings?

The term that best describes a material that is potentially harmful with a crumbly texture, often found in older buildings, is asbestos. Asbestos is a group of naturally occurring minerals that have been widely used in construction materials due to their fire-resistant properties. It was commonly used in insulation, flooring, and roofing materials in buildings constructed before the 1980s.

Asbestos can become dangerous when it deteriorates, releasing tiny fibers into the air that can be inhaled, leading to serious health problems, including lung disease and cancer. The crumbly texture is significant because it indicates that the material may be friable, meaning it's more likely to release fibers into the air when disturbed.

While lead-based paint is also a hazardous material found in older buildings, it primarily presents a risk through lead poisoning rather than through a crumbly texture. Radon gas is a radioactive gas that can accumulate in buildings, particularly basements, but does not have a physical form or texture. Superfund areas are locations designated by the Environmental Protection Agency for clean-up of hazardous waste, but this term does not specifically describe a material associated with older buildings.

Understanding the characteristics and risks associated with asbestos is crucial for real estate professionals, especially when dealing with the sale or renovation of
