Under 1926.153 (related to boilers and pressure vessels), which 1910 boiler provisions are incorporated for construction?

Section 1926.153 maps several construction requirements to the boiler provisions in [1910.110]. For example, 1926.153(a)(3) maps to 1910.110(a)(4), and other paragraphs map to [1910.110(d)] provisions; see the detailed cross-references in Appendix A to Part 1926.

Under 1926.1101, do asbestos remediation activities on residential buildings fall under the construction asbestos standard or the general industry asbestos standard?

Asbestos remediation activities involving asbestos-containing building materials (ACBM) in demolition, repair, or cleanup work are covered by the construction asbestos standard, [1926.1101], not the general industry standard [1910.1001], when the described activities involve ACBM; see OSHA's interpretation: "Application of Asbestos Standards to repair and maintenance operations" and the Asbestos remediation protocols interpretation (Nov. 14, 2024).

Under 1910.147(f)(1), is there an OSHA-allowed alternative when power is required to test or position machinery instead of keeping it locked out?

Yes; 1910.147(f)(1) allows temporary removal of lockout/tagout devices and re-energization when necessary to test or position machines, but only if the employer follows the required sequence of protections (clear the machine, remove employees from the hazard area, remove devices as specified, energize for testing with employee protections, then de-energize and reapply controls) and documents the procedure; see OSHA's interpretation on the minor servicing exception and temporary re-energization procedures in the Minor servicing exception clarification (Oct. 21, 2024).

Under 1910.119, does storing multiple pre-charged appliances with Category 1 flammable refrigerant in one warehouse trigger Process Safety Management (PSM) coverage?

Yes; storage and on-site movement of pre-charged appliances containing a Category 1 flammable gas meet the definition of a "process" and, if the aggregate weight of the refrigerant on site in one location meets or exceeds 10,000 pounds, the operation is PSM-covered under [1910.119]; see OSHA's interpretation "PSM flammable gas aggregation" (June 6, 2024) at https://www.osha.gov/laws-regs/standardinterpretations/2024-06-06 and the PSM standard 1910.119.

Under 1910.135(a)(1), are crane operators required to wear hard hats when lifting loads overhead?

Yes; employers must ensure workers wear head protection when there is potential for head injury from falling objects, so crane operators who are exposed to overhead hazards must wear helmets that meet an accepted consensus standard; see 1910.135(a)(1) and OSHA's interpretation "Head protection for crane operators" (June 6, 2024) at https://www.osha.gov/laws-regs/standardinterpretations/2024-06-06-2.

Under 1910.28(b)(11)(ii) note and related provisions, how should stair width be measured when handrails are present?

Measure standard stair width between vertical barriers (walls, stair rails, guardrails), and do not treat handrails as vertical barriers that reduce the required minimum width; see OSHA's stair-width guidance in the "Stair width measurement guidance" interpretation (Oct. 17, 2024) at https://www.osha.gov/laws-regs/standardinterpretations/2024-10-17 and see the stair/handrail provisions in 1910.28.

Under 1910.23(e) (mobile ladder stand platforms), what are the step dimensions and platform guardrail requirements for different heights?

Mobile ladder stand platforms must have steps at least 16 inches wide, uniformly spaced steps with a rise not more than 10 inches and depth at least 7 inches, and platform guardrails depend on platform height: platforms 4–10 feet require handrails and midrails, and platforms above 10 feet require guardrails and toeboards; see 1910.23(e) and OSHA's "Mobile ladder stand requirements" interpretation (June 6, 2024) at https://www.osha.gov/laws-regs/standardinterpretations/2024-06-06-0.

Under 1910.134, how does OSHA define an oxygen-deficient atmosphere and does that definition apply to civilian employees in military facilities?

OSHA defines an oxygen-deficient atmosphere as having less than 19.5% oxygen by volume, and that definition and standard requirements apply to civilian employees working at military facilities when they are performing work not uniquely military; see 1910.134 and OSHA's interpretation "Oxygen-deficient atmospheres in HVAC" (July 16, 2024) at https://www.osha.gov/laws-regs/standardinterpretations/2024-07-16.

Under the COVID-19 recordkeeping rules adopted in 1910.502, is OSHA currently enforcing the COVID-19-specific recordkeeping and reporting requirements?

No; effective immediately and until further notice, OSHA announced it will not enforce the COVID-19 recordkeeping and reporting requirements adopted under 29 CFR 1910.502, including the COVID-19 log and certain reporting provisions, though OSHA will continue to enforce other applicable recordkeeping requirements under 29 CFR part 1904; see OSHA's enforcement stay memorandum "COVID-19 recordkeeping enforcement stay" (Feb. 5, 2025) at https://www.osha.gov/laws-regs/standardinterpretations/2025-02-05.

Under 1910.177, does the rim wheel servicing standard apply to C-type light truck tires that are not labeled "LT"?

Yes; C-type European Commercial Metric light truck tires may be treated under the servicing requirements of [1910.177] when their installation, use, and servicing are substantially similar to LT tires, and deviations that have no direct or immediate relationship to safety may be considered de minimis; see OSHA's interpretation "Scope of rim wheel servicing" (Aug. 1, 2024) at https://www.osha.gov/laws-regs/standardinterpretations/2024-08-01 and the rim servicing standard 1910.177.
