Cal/OSHA's New 2026 Rules: Lead, Confined Spaces, and Training Records Explained for Contractors

Every January I sit down with each of my clients and walk through what changed in Title 8 while they were busy building things. This year the list is heavier than usual. Three changes took effect on January 1, 2026 that touch almost every California contractor I work with: a revised confined space standard for construction, stricter medical removal triggers under the lead standards, and a new state law on training records in personnel files.

I have read the adopted regulatory text and the current Title 8 sections behind each of these, and this post covers what the changes say, who they hit, and what to do about them. As always, the citations are here so your team can verify everything against dir.ca.gov directly.

What changed in Cal/OSHA's confined space rules for construction?

On November 4, 2025, the Occupational Safety and Health Standards Board filed its adopted revisions to the Construction Safety Orders on confined spaces, covering 8 CCR sections 1951, 1952, 1953, 1955, 1956, and 1960, along with section 5156 in the General Industry Safety Orders. The Office of Administrative Law approved the text with an effective date of January 1, 2026.

The headline change is in section 1952. The revised rule spells out a specific sequence for identifying confined spaces on a construction site, and it puts a competent person at the center of it:

• A competent person must conduct an initial survey of the work area for confined spaces existing at the time work begins.
• A competent person must periodically inspect the work area with enough frequency to identify new confined spaces as construction creates or uncovers them.
• The employer must inform its employees and the controlling contractor of each new confined space discovered or created by construction or demolition activity.
• A competent person must identify which confined spaces are permit-required spaces, through evaluation and testing as necessary.

That periodic re-survey duty deserves attention. Construction sites manufacture confined spaces as they go. A vault gets set, a tank gets placed, an excavation gets covered, and a space that did not exist at mobilization now needs evaluation. The old approach of surveying once at kickoff no longer satisfies the text. If you are unsure who qualifies to run those surveys, I broke down the role in my post on competent person requirements.

The revisions also tighten the vocabulary and several operational rules:

• "Entry employer" now means any employer whose employees enter or that decides an employee it directs will enter a permit space, and the text notes that refusing to decide counts as an implicit decision to allow entry. Entry employers must have a written permit space program implemented at the construction site, available for inspection before and during entry operations.
• The hazardous atmosphere definition for combustible dust now references 20 percent of the minimum explosive concentration, a defined term, in place of the old vision-obscured-at-5-feet test, which survives only as an approximation note.
• Lockout and tagout are now defined within the article, and tagout is acceptable only where it gives equivalent protection or lockout is infeasible and stored energy has been rendered safe.
• Atmospheric testing still runs in the fixed order of oxygen, then flammables, then toxics, and the revised text confirms that concurrent testing with a multi-gas meter is acceptable as long as readings are examined in that order.
• Flammable atmospheres: where the entry employer cannot get flammable gases, mists, or vapors below 10 percent of the lower flammable limit, entry is prohibited unless the space is rendered inert, entrants wear IDLH-rated respiratory protection under section 5144(d)(2), and all additional physical hazards are eliminated or isolated.
• Rescue under section 1960 now leads with a duty to ensure rescue services at the site are trained, immediately available, properly equipped, and capable of performing permit space rescue. Non-entry retrieval is the default unless it would increase overall risk or would not help.
• Training under section 1956 must be provided at no cost to the employee, and workers who are not authorized to perform entry rescues must be trained on the dangers of attempting one. That last item tracks the worst pattern in confined space fatalities, the untrained coworker who climbs in after a downed entrant.

The amendment to section 5156 reroutes construction operations to Article 37 of the Construction Safety Orders, so there is no longer any argument about whether a construction crew can operate under the looser general industry confined space provisions.

What are Cal/OSHA's stricter lead requirements for 2026?

California's overhauled lead standards, 8 CCR 1532.1 for construction and 5198 for general industry, largely took effect January 1, 2025. That earlier phase set the permissible exposure limit at 10 micrograms per cubic meter as an 8-hour time-weighted average and the action level at 2 micrograms per cubic meter, both dramatic reductions from the numbers a generation of contractors memorized.

What changed on January 1, 2026 is the medical removal math, and I pulled this straight from the current text of section 1532.1(k). An employer must temporarily remove a covered employee from lead exposure when any of these is true:

• The last blood lead test is at or above 30 micrograms per deciliter. This trigger was already in effect.
• Effective January 1, 2026, the last two blood lead test results are at or above 20 micrograms per deciliter.
• Effective January 1, 2026, the average of all blood lead tests over the last 6 months is at or above 20 micrograms per deciliter, unless the most recent test is below 15.

Return to the former job requires two consecutive blood lead tests, taken at least 30 days apart, both below 15 micrograms per deciliter. Removed employees are entitled to medical removal protection benefits, meaning the removal cannot quietly become a layoff.

For demo crews, painters, plumbers cutting old pipe, and anyone disturbing pre-1978 coatings, the practical effect is that blood lead levels which passed without comment a few years ago now trigger mandatory removal. If your exposure assessments and blood lead monitoring program have not been rebuilt around the 2025 numbers, the 2026 removal triggers make that overdue work urgent.

What are the new training records requirements for California employers?

This one is a Labor Code change rather than a Title 8 regulation. Senate Bill 513 amended Labor Code section 1198.5, the personnel file statute, effective January 1, 2026. Personnel records that employees and former employees have a right to inspect and copy now expressly include education and training records, and each training record must identify:

• the employee's name,
• the name of the training provider,
• the duration and date of the training,
• the core competencies covered, including any skills in equipment or software, and
• the resulting certification or qualification, if any.

Employers generally have 30 days to respond to a written request. For safety training specifically, this stacks on top of obligations you already carry. Cal/OSHA training documentation has long been an IIPP requirement under 8 CCR 3203, something I covered in detail in my post on Cal/OSHA IIPP requirements for construction companies. The new wrinkle is the level of detail per record and the fact that the request can come from the employee side, not only from a compliance officer. A sign-in sheet with a topic scrawled at the top does not capture provider, duration, competencies, and resulting certification.

What should California contractors do before their next inspection?

Here is the punch list I am running with my own clients this quarter:

1. Rewrite the confined space program to reflect the Article 37 revisions: name the competent person for surveys, build the periodic re-survey into the schedule, update the definitions, and confirm rescue arrangements meet the revised section 1960.
2. Re-check lead exposure assessments against the 2 microgram action level and confirm your clinic and your recordkeeping can catch the two-test and 6-month-average removal triggers.
3. Rebuild the training record template so every course generates a record with the five SB 513 elements.
4. Assume these topics come up during enforcement. New standards get inspection attention in their first year, and document requests are where most citations start. My walkthrough of what to expect during a Cal/OSHA inspection explains how those requests unfold.

FAQ

Do the 2026 confined space rules apply to residential contractors?

Yes. Article 37 applies to construction operations generally, and the amended section 5156 removes any path to treating construction confined space work under the general industry provisions.

We already follow federal OSHA's construction confined space rule. Are we covered?

Mostly, but not entirely. The California revisions parallel the federal Subpart AA framework while adding state-specific details, including the explicit survey duties and the training-at-no-cost language. On California sites, Title 8 is the enforceable text.

Does the lead standard apply if we only occasionally disturb old paint?

It can. The construction lead standard has presumed exposure levels for listed trigger tasks until you complete an exposure assessment, and the action level of 2 micrograms per cubic meter is low enough that intermittent work can still be covered. Get the assessment done rather than guessing.

Do the SB 513 training record rules cover safety training only?

No. The statute covers education and training records generally. Safety training is where contractors have the most volume, so it is where the gap usually shows.

Where can I verify these changes myself?

The confined space rulemaking file, including the OAL-approved text, is on the Standards Board pages at dir.ca.gov, and the current lead standard text is at dir.ca.gov/title8/1532_1.html. For SB 513, the amended Labor Code section 1198.5 is on the California Legislative Information site.
