Answer :
Final answer:
The definitions for containment, confinement, and control are primarily found in OSHA regulations. OSHA establishes Permissible Exposure Limits (PELs) to regulate worker exposure to harmful substances. Option B is correct.
Explanation:
The definitions for containment, confinement, and control are found in OSHA regulations. The Occupational Safety and Health Administration (OSHA) establishes legal standards for worker exposure in the United States, which include legally enforceable acceptable exposure levels or controls resulting from Congressional or Executive mandate. These safety measures are considered part of the environmental and occupational safety standards and are designated to protect workers from various hazards.
Specifically, OSHA's exposure standards, also known as Permissible Exposure Limits (PELs), are designed to regulate worker exposure to harmful substances. In the context of environmental regulation, the EPA sets standards such as Maximum Contaminant Levels (MCLs) for contaminants in drinking water, which are different from occupational standards and focus on public health and the environment.
