New York State Asbestos Investigator Practice Exam

What is considered a significant risk factor when evaluating asbestos exposure?

1. Type of building materials used

2. Presence of pets in the environment

3. Pollutants like cigarettes in the air

4. Temperature and humidity levels

The correct answer is: Pollutants like cigarettes in the air

Significant risk factors when evaluating asbestos exposure primarily focus on elements that can influence the likelihood and intensity of that exposure. Among the choices, the presence of pollutants like cigarettes in the air can elevate the risk when asbestos exposure is a concern. Smoking, particularly when combined with asbestos exposure, can lead to a heightened risk of respiratory diseases, including lung cancer. This is due to the synergistic effect of smoking and asbestos, which can greatly increase the harmful health outcomes compared to exposure to asbestos alone. Factors such as the type of building materials used, while relevant, are often considered in terms of the asbestos content specifically, rather than as a general risk factor for health outcomes. The presence of pets does not have a recognized direct influence on asbestos exposure risk. Temperature and humidity levels are factors that may influence the dispersion of asbestos fibers but are not direct risk factors in themselves for health effects related to exposure. Thus, the presence of airborne pollutants, particularly in conjunction with asbestos, stands out as a significant risk factor due to its established link to severe health consequences.
