New York State Asbestos Investigator Practice Exam

What type of asbestos material is described as "non-friable"?

1. Material that can be easily crumbled by hand

2. Material that cannot be powdered when dry

3. Any material that is free of asbestos

4. Material that is in liquid form

The correct answer is: Material that cannot be powdered when dry

Non-friable asbestos material refers to substances that cannot be easily crumbled or powdered when dry. This characteristic is significant in understanding the potential health risks associated with asbestos exposure. Non-friable materials typically include products like ceiling tiles, floor tiles, and asbestos cement sheets, which are bound in a way that prevents the fibers from being released into the air unless they are subjected to significant mechanical disruption or damage. Recognizing non-friable asbestos is crucial for safety assessments and management practices. While these materials are generally considered to pose a lower risk than friable asbestos (which can be easily crumbled and generate airborne fibers), they still require careful handling and proper remediation measures if they become damaged. In contrast, materials that are easily crumbled by hand would be classified as friable, while any material free of asbestos would not fit the description of asbestos material at all. Liquid asbestos products do not fit within the standard definitions used in asbestos management. Therefore, the correct understanding of non-friable materials is foundational for ensuring public health and safety in environments where asbestos is present.
