Asbestos Hazard Emergency Response Act (AHERA) Certification Practice Exam

Can electrical systems contain asbestos, and if so, where?

1. Only inside circuit breakers

2. Yes, around wiring and electrical boxes

3. Only in the outer shell of electrical devices

4. No, electrical systems are asbestos-free

The correct answer is: Yes, around wiring and electrical boxes

The response indicating that electrical systems can contain asbestos, particularly around wiring and electrical boxes, is accurate given the historical use of asbestos in various building materials. Asbestos was commonly utilized for its fire-resistant properties, and in older buildings, it may be found in insulation materials used around electrical wiring to prevent overheating and electrical fires. Additionally, electrical boxes might have asbestos-containing materials as part of their insulation or as a component of fireproofing measures. In contrast, other options suggest limited or no presence of asbestos in electrical systems. The idea that asbestos is found only inside circuit breakers or only in the outer shell of electrical devices does not reflect the broader reality of asbestos use in construction materials. Moreover, the assertion that electrical systems are entirely asbestos-free overlooks the fact that many older construction practices incorporated asbestos in various components for safety and performance purposes.
