Technical Data Center
OSHA's Technical Data Center (TDC) provides a full range of professional reference and research services primarily to OSHA employees throughout the nation who rely upon the Center to maintain and locate materials to support their research. TDC includes a Docket Office and a Technical Information Resource Center.
OSHA is committed to increasing public participation in the development of occupational safety and health regulations and other related documents, and to also ensuring transparency in the Agency's rulemaking process (PDF*). The Docket Office serves as OSHA's central repository and dissemination center for all Agency rulemaking documents. "Dockets" serve as a source of current and historical information on Agency activities, including comments received from the public to inform Agency decisions. The Docket Office can assist the general public in the following ways:
- Answering questions about how to access and properly use the public e-rulemaking portal at Regulations.gov, which is a multi-agency website that serves as an on-line clearinghouse for materials related to OSHA rulemaking and non-rulemaking activities, and which also serves as OSHA's official electronic public docket and on-line comment system.
- Providing information about which Agency actions are currently open for comment and appropriate procedures to follow when submitting a comment, which can be done electronically at Regulations.gov, via fax at (202) 693-1648, or in person in TDC at the address noted in the “Visit” box on this webpage.
- Facilitating access to the Agency's Public Reading Room to inspect physical docket items and other materials that may be restricted from view on Regulations.gov.
- Processing requests to authenticate docket records for third-party litigation purposes.

The Center can assist the general public in the following ways:
