What kind of exposure does Oregon OSHA regulate regarding lead?

Surface exposure levels
Inhalation exposure levels
Drinking water contamination levels
Residential exposure standards

The correct answer is: Inhalation exposure levels

Oregon OSHA regulates inhalation exposure levels concerning lead due to the significant health risks posed by airborne lead particles. In occupational settings, workers can be exposed to lead dust or fumes through various activities such as construction, painting, or demolition. Inhalation of lead can lead to serious health issues, including neurological damage and other systemic effects. Therefore, OSHA guidelines focus on monitoring and controlling airborne lead concentrations to ensure worker safety. These regulations are crucial for maintaining a safe workplace and mitigating the risk of lead poisoning. While surface exposure levels, drinking water contamination, and residential exposure standards are important public health concerns, they are typically governed by different agencies or regulations outside the specific purview of Oregon OSHA in relation to workplace exposures.
