Asbestos Hazard Emergency Response Act (AHERA) Certification Practice Exam

How can family members of an asbestos worker be exposed to asbestos fibers?

1. Through direct lines of communication

2. By consuming contaminated food

3. Via fibers on clothing or shoes brought home

4. Through shared water sources

The correct answer is: Via fibers on clothing or shoes brought home

Family members of an asbestos worker can be exposed to asbestos fibers primarily through fibers on clothing or shoes that are brought home. When an individual who has worked in an environment where asbestos is present leaves the workplace, they may carry microscopic asbestos fibers on their work clothes or shoes. This transfer can occur without the worker being aware of it, allowing fibers to be released into the home environment, where family members may inadvertently inhale or come into contact with them. The dangers of asbestos exposure extend beyond the workplace, as the contaminated clothing can spread fibers throughout the home, particularly in laundry areas or living spaces where clothing is handled. This calls attention to the importance of proper hygiene and protective practices in managing asbestos exposure, including changing clothes and showering before returning home. The other options do not represent typical methods of asbestos fiber exposure. While communication lines could be significant for sharing information about safety practices, they do not physically transfer asbestos fibers. Consuming contaminated food could theoretically occur if food has been prepared in a contaminated area, but it is not a common or primary route of exposure. Similarly, shared water sources are not a recognized vector for asbestos contamination, as asbestos does not readily dissolve or contaminate water in a way that would lead to exposure from drinking. Thus, the
