By EPA definition, an asbestos-containing material contains more than what percent asbestos?

• A. 0.5 percent
• B. 1 percent
• C. 2 percent
• D. 5 percent

Answer: (B)

Regulatory definitions use a specific weight threshold to classify materials. The EPA defines asbestos-containing material as material that contains more than 1 percent asbestos by weight. That means any material with asbestos content above 1% is considered ACM and subject to the corresponding regulations for management and abatement. Therefore, the percent in question is 1 percent—the cutoff value for what makes a material asbestos-containing. If a material is at 1% or less, it isn’t automatically labeled ACM under this definition, though its presence may still require caution and assessment based on other factors like friability and exposure potential.
