Final answer:
Dosimetry records, which monitor radiation exposure, are not mentioned as a required posting and therefore are the correct answer to the question. Other documents, such as the 'Notice to Employees', permits, and regulations, must be posted in line with various OSHA mandates.
Step-by-step explanation:
When navigating through regulatory requirements in a workplace environment, especially those pertaining to safety and health audits, it is essential to understand which documents and records are required to be prominently displayed or posted. Items such as 'Notice to Employees', a copy of the permit, and a copy of regulations are typically required to be accessible and visible to all employees for the purpose of maintaining standards and informing everyone of their rights and responsibilities. Such requirements stem from directives including, but not limited to, the Occupational Safety and Health Administration (OSHA) standards.
According to the information provided, an employer's responsibility includes, among others, providing safety training in an understandable language, keeping accurate records of work-related injuries and illnesses, providing required personal protective equipment at no cost, and posting OSHA citations and injury and illness summary data where it is visible to the workers. Notably, the employer is also mandated to prominently display the official OSHA Job Safety and Health poster.
