New York State Asbestos Investigator Practice Exam

Among the following, which is NOT a typical material that may contain asbestos?

1. General office supplies

2. Roofing felt

3. Brake linings

4. Pipe insulation

The correct answer is: General office supplies

General office supplies typically do not contain asbestos, making this choice correct. Asbestos is a naturally occurring mineral that was commonly used in various industrial and construction materials due to its heat-resistant properties and durability. Materials that are known to contain asbestos include roofing felt, brake linings, and pipe insulation, as they were widely utilized in building, automotive, and insulation applications during times when asbestos use was prevalent. Roofing felt, for example, often used in construction projects, especially prior to regulations limiting asbestos use, contained asbestos fibers for added durability. Brake linings also contained asbestos due to its heat resistance, which is essential for performance and safety in automotive applications. Pipe insulation was frequently made with asbestos to effectively manage heat and prevent energy loss in plumbing systems. In contrast, general office supplies, such as paper products, staplers, and filing equipment, are not known to incorporate asbestos, making them an unlikely source for exposure.
