Oregon Construction Contractors (CCB) Practice Test

The correct answer reflects safety regulations regarding lead exposure in the workplace. In Oregon, as per Occupational Safety and Health Administration (OSHA) standards that inform state regulations, the permissible exposure limit (PEL) for lead is set at 50 micrograms per cubic meter of air averaged over an 8-hour workday. This is designed to protect workers from the harmful effects of lead, which can result in serious health issues, including neurological damage, kidney problems, and reproductive issues.

Understanding the significance of this limit is essential for construction contractors and workers. It underlines the importance of implementing safety measures to minimize lead exposure, such as proper ventilation, personal protective equipment, and regular monitoring of air quality on job sites where lead-related work is conducted.

Other options indicating lower or higher exposure limits do not align with established safety standards for lead, emphasizing the critical role of adhering to the correct regulations to ensure workers' health and safety.
