New York State Asbestos Investigator Practice Exam

Which of the following is a significant advantage of asbestos in construction?

1. Low cost

2. Lightweight

3. Fracture resistance

4. Heat resistance

The correct answer is: Heat resistance

Heat resistance is a significant advantage of asbestos in construction. Asbestos fibers have unique properties that make them highly effective in providing heat resistance. They are known for their ability to withstand high temperatures without degrading, which makes them valuable in applications where fireproofing is crucial, such as in insulation for pipes, boilers, and fireproofing materials. This property not only enhances the safety of structures but also allows for more efficient energy use and can prolong the life of materials in high-temperature environments. The other characteristics, while they might sound beneficial, do not encompass the primary reason for asbestos's historical use in construction. For instance, while asbestos can be low cost, it is worth noting that the long-term health risks associated with its use can lead to significant costs in remediation and legal liabilities. Its lightweight nature can be an advantage, but that quality is less significant than heat resistance in many construction scenarios. Fracture resistance is also a notable property, yet it pales in comparison to the critical need for materials that can withstand extreme conditions without compromising safety.
