What type of document is NEHC Technical Manual, TM 6260.51.99 series?

The correct answer is a guidance document because the NEHC Technical Manual, TM 6260.51.99 series is designed to provide recommendations, best practices, and information to support the implementation of hearing conservation programs and related practices. Guidance documents typically help organizations understand and comply with regulations and policies by offering clarity on expectations and methods, rather than imposing legal requirements as regulations do.

Unlike a regulation, which mandates specific actions to be taken by organizations, guidance documents are more flexible and serve to assist individuals and entities in achieving compliance in a practical manner. They are not personal accounts, which would describe individual experiences or opinions, nor are they financial reports, which focus on monetary aspects of an organization. Therefore, the purpose and nature of the NEHC Technical Manual clearly align it with being a guidance document.
