Scientific diving guidelines

The purpose of Appendix B is to provide guidelines for scientific diving operations.

• The Appendix is titled "Guidelines for Scientific Diving" and is part of 1926 Subpart Y.
• The Appendix notes that the requirements for construction work under this Appendix are identical to those set forth at Appendix B to Subpart T of Part 1910.

You can find the official text of the scientific diving guidelines in Appendix B to Subpart Y of Part 1926 and in the corresponding Appendix B to Subpart T of Part 1910.

• The Appendix B to Subpart Y is referenced on OSHA's construction standards page at https://www.osha.gov/laws-regs/regulations/standardnumber/1926.
• The document explicitly links those requirements to Appendix B to Subpart T of Part 1910 for the civilian/general industry guidance that corresponds to these scientific diving guidelines.

No — for construction work the requirements under Appendix B to Subpart Y are identical to those in Appendix B to Subpart T of Part 1910.

• The Appendix itself states the requirements applicable to construction work under this Appendix B are identical to the text at Appendix B to Subpart T of Part 1910.
• See the construction standard listing at 1926 Subpart Y which references that equivalence.

Appendix B is presented as guidelines for scientific diving; for construction diving the Appendix states the applicable requirements are identical to those at Appendix B to Subpart T of Part 1910.

• Appendix B is titled "Guidelines for Scientific Diving" and is linked from OSHA's construction standards at https://www.osha.gov/laws-regs/regulations/standardnumber/1926.
• The Appendix makes clear the construction-applicable requirements mirror Appendix B to Subpart T of Part 1910, so those provisions should be treated as the applicable OSHA guidance for scientific diving in construction contexts.

If the work involves diving activities performed as part of a construction project, the scientific diving guidelines in Appendix B apply and the construction-applicable requirements are the same as in Appendix B to Subpart T of Part 1910.

• Check 1926 Subpart Y Appendix B for the title and scope of the guidelines.
• For specifics about which provisions to follow, refer to Appendix B to Subpart T of Part 1910, since the Appendix states equivalence for construction work.

OSHA provides Federal Register publication citations for Appendix B: 58 FR 35190 (June 30, 1993) and 61 FR 31427 (June 20, 1996).

• The Appendix text on the OSHA construction standards page includes those Federal Register references and is accessible via 1926 Subpart Y.
• The Appendix also points users to the equivalent text in Appendix B to Subpart T of Part 1910.

Appendix B provides the guidelines for scientific diving and, for construction-related diving, states the requirements are identical to those in Appendix B to Subpart T of Part 1910; employers should therefore consult those OSHA appendices for applicable requirements.

• Start with 1926 Subpart Y Appendix B to identify the scientific diving guidance.
• Because the Appendix ties the construction-applicable requirements to Appendix B to Subpart T of Part 1910, employers should use that text as the operative guidance for compliance.

The Appendix identifies the e-CFR as the GPO source for the codified text of the guidelines.

• The Appendix metadata includes an e-CFR link shown on the OSHA page for the Appendix (see 1926 Subpart Y), and the Appendix itself lists the e-CFR entry as a source for the text (the e-CFR link appears in the Appendix metadata).
• For the OSHA regulatory references that mirror this guidance, consult Appendix B to Subpart T of Part 1910.

No specific Letters of Interpretation are linked with Appendix B to Subpart Y in this guidance text.

• The Appendix on OSHA's construction standards page does not list related interpretation letters and instead points readers to the equivalent Appendix B to Subpart T of Part 1910 for the matching guidance.
• If you need formal interpretations, search OSHA's interpretations pages or contact OSHA for current letters related to scientific diving under 1926 Subpart Y.

Reference it as "Appendix B to Subpart Y of Part 1926 — Guidelines for Scientific Diving."

• That is the official title shown on OSHA's construction standards entry at https://www.osha.gov/laws-regs/regulations/standardnumber/1926.
• When cross-referencing guidance, note the Appendix indicates equivalence with Appendix B to Subpart T of Part 1910.

Appendix B provides specific guidelines for scientific diving and links the construction-applicable requirements to the matching Appendix B in general industry, but it does not state that scientific diving and commercial diving are identical.

• The Appendix is explicitly titled "Guidelines for Scientific Diving" and is referenced on the construction standards page at https://www.osha.gov/laws-regs/regulations/standardnumber/1926.
• For the construction context, OSHA directs users to the equivalent content in Appendix B to Subpart T of Part 1910, which is the corresponding general-industry appendix addressing scientific diving.

The Appendix points you to the scientific diving guidelines as codified in the OSHA appendices; for construction work it explicitly states the requirements are identical to those in Appendix B to Subpart T of Part 1910.

• Use the Appendix reference at 1926 Subpart Y and then consult the corresponding Appendix B to Subpart T of Part 1910 for the operative guidelines that apply to scientific diving details.

The intended audience is persons and employers involved in scientific diving activities, including those working under construction-related diving circumstances covered by Part 1926.

• The Appendix is titled "Guidelines for Scientific Diving" and appears on OSHA's construction standards page at https://www.osha.gov/laws-regs/regulations/standardnumber/1926.
• For construction-specific applicability, the Appendix states the requirements match those in Appendix B to Subpart T of Part 1910.
