Final answer:
Citations for workplace safety violations must be posted for at least 3 working days or until the violation is abated, whichever is longer, to inform employees and ensure compliance.
Step-by-step explanation:
The question relates to the requirement for posting citations concerning workplace safety violations. In the context of worker safety regulations, such as those enforced by the Occupational Safety and Health Administration (OSHA) in the United States, citations for safety violations must be posted near the area of each violation for at least 3 working days or until the violation is abated, whichever is longer. This requirement ensures that employees are aware of the violations found during inspections and that measures are taken to correct these hazards as part of compliance efforts.
