Final answer:
Prohibited actions in areas with occupational exposure hazards include eating, drinking, leisure activities, and excessive socializing; these regulations are set to protect workers' health and maintain safety.
Step-by-step explanation:
The question addresses what actions are prohibited in areas with a likelihood of occupational exposure to hazards. In these areas, certain actions such as eating and drinking are prohibited to maintain high safety standards and prevent the ingestion or absorption of hazardous materials. Other prohibited actions may include using the workspace for leisure activities, which can distract from awareness of potential risks, or socializing, which can reduce focus on necessary safety protocols. Although sitting is not inherently a risky behavior, it could be forbidden if it impedes safe working conditions or emergency responses. Occupational safety regulations, in accordance with the Occupational Health and Safety Act (OHSA) and OSHA standards, mandate these prohibitions and also require employers to provide safe working environments, reduce hazards through engineering controls or safer practices, and inform and train workers about potential dangers.
