If your crews scrape, sand, blast, torch, weld, or demolish anything with old paint on it, you are working under Title 8, Section 1532.1, and the version that took effect January 1, 2025 is a very different standard from the one most contractors learned. The action level dropped to 2 micrograms per cubic meter, the permissible exposure limit dropped to 10, blood lead triggers were cut sharply, and the presumption of exposure now reaches into tasks that used to pass without a second look. Painting contractors, demolition crews, bridge and steel contractors, and anyone bidding Caltrans or public works jobs need to understand what changed before an inspector or a blood test explains it for them.
Who Is Covered
Section 1532.1(a) applies to all construction work where an employee may be occupationally exposed to lead. If lead is present in a coating, mortar, solder, or the metal itself and a construction task can disturb it, the section applies. General industry work, such as a radiator shop or a battery plant, falls under Section 5198 instead.
Two numbers anchor everything else. The action level is now an airborne concentration of 2 micrograms per cubic meter (2 µg/m³), measured without regard to respirator use. The permissible exposure limit is 10 µg/m³ as an 8-hour time-weighted average. For comparison, the old PEL was 50.
Trigger Tasks and Presumed Exposure
The feature of Section 1532.1 that catches contractors is subsection (d)(2). Until you have performed an exposure assessment and documented that a task does not exceed the PEL, you must treat employees performing certain listed tasks as if they are exposed at a presumed level, and provide the protections that go with it. The current standard groups those tasks into three levels:
- Presumed above the PEL, up to ten times the PEL: where lead-containing coatings or paint are present, manual demolition of structures such as drywall, manual scraping, and heat gun applications. The same presumption applies to any other task where the employer has reason to believe exposure may exceed the PEL.
- Presumed above 100 µg/m³ (ten times the PEL): where lead-containing coatings or paint are present, manual sanding and power tool cleaning, grinding, or sanding with dust collection systems; and spray painting with lead paint.
- Presumed above 500 µg/m³ (fifty times the PEL): using lead-containing mortar or lead burning; and, where lead-containing coatings or paint are present, rivet busting, power tool cleaning, grinding, or sanding without dust collection, cleanup where dry expendable abrasives are used, abrasive blasting enclosure movement and removal, abrasive blasting, welding, torch cutting, and torch burning.
Note what moved. Manual sanding and power tool work with dust collection are now presumed at ten times the PEL. Until your own air sampling says otherwise, the interim protections for those levels apply: appropriate respiratory protection, protective clothing and equipment, change areas, hygiene and eating facilities, regulated areas, medical surveillance, and training. Shower facilities are required in the top tier. The assessment is the only way off the presumption, and it has to be documented.
The Compliance Program and Pre-Job Notification
Whenever exposures exceed the PEL, subsection (e) requires a written compliance program. It has to describe each activity in which lead is emitted, the equipment and controls used, the specific engineering and work practice means you will use to reach compliance, air monitoring data, an implementation schedule, administrative controls, and how you will coordinate with other contractors on the site. The written program must be revised and updated at least every six months to reflect its current status.
This is where Caltrans and public works submittals come in. Agencies that own painted steel and older concrete structures routinely require a project-specific lead compliance plan as a submittal before work begins, and they review it against Section 1532.1. The gap I see most often is a company-wide boilerplate plan that never names the structure, the tasks, or the monitoring plan for the job in front of it. A reviewer rejects that, and an inspector treats it as no plan at all. Write it for the project.
Subsection (p) requires written notice to the nearest Cal/OSHA district office, received at least 24 hours before the work starts, whenever the job includes trigger tasks. The exceptions are narrow: the amount of lead-containing material to be disturbed is less than 100 square feet or 100 linear feet; the only work is torch cutting or welding not exceeding one hour per shift; or the lead content of the material is below 0.5 percent by weight, 5,000 parts per million, or 1.0 milligram per square centimeter. If you cannot document that you fall inside one of those exceptions, send the notice.
The notice must include the employer’s name, address, and phone number; the job address and the precise physical location of the lead work; projected start and completion dates; the approximate number of workers; the type of structure; the amount of material in square or linear feet; a description of the work and the work practices; the supervisor’s name; and the lead content if known. Missing this notice is one of the easiest citations an inspector can write.
Blood Lead Testing and Medical Removal
Medical surveillance under subsection (j) is triggered by exposure at or above the action level, with limited exceptions for employees exposed on only a small number of days per year and never above certain daily levels. Given a 2 µg/m³ action level, most crews performing trigger tasks will be in the program. Blood lead sampling is required at least every two months for the first six months after placement and every six months thereafter.
The blood lead thresholds are the part of the 2025 revision that changes how you manage people:
- A blood lead level at or above 10 µg/dL requires a written elevated blood lead response plan, and sampling at least every two months until two consecutive results are below 10.
- At or above 20 µg/dL, sampling moves to monthly and a medical examination is required if none has been done in the preceding 12 months.
- At or above 30 µg/dL, the employee must be temporarily removed from lead exposure under subsection (k). Return to the former job requires two consecutive tests, at least 30 days apart, both below 15 µg/dL.
- Medical removal protection benefits, meaning maintained earnings, seniority, and benefits, run up to 18 months per removal.
For context, the old removal trigger was 50 µg/dL. That cost is a strong argument for controls and hygiene done right from day one.
CDPH Certification and Title 17
Section 1532.1(l)(3) requires that employees and supervisors engaged in lead-related construction work, as defined in Title 17, Section 35040, who have been shown to be exposed at or above 50 µg/m³ as an 8-hour TWA, be trained by a provider accredited by the California Department of Public Health and certified by CDPH. Title 17 defines lead-related construction work as construction, alteration, painting, demolition, salvage, renovation, repair, or maintenance of a residential or public building that may result in significant exposure to lead. Under Title 17, Section 36100, abatement work must be performed only by a certified lead supervisor or certified lead worker, following a written abatement plan, with a CDPH 8551 notification delivered to the Department at least five days before the work.
Cal/OSHA governs worker exposure on every construction site; CDPH certification governs who may do the work in homes, schools, hospitals, stores, and other public buildings. A painting contractor on a pre-1978 apartment building typically needs both.
Records
Subsection (n) sets the retention periods. Exposure assessment records and medical surveillance records follow Section 3204, which means 30 years for exposure data and duration of employment plus 30 years for medical records. Written compliance program reviews and elevated blood lead response plans are kept for three years. Training records are kept for three years. Objective data used to claim an exemption from the standard must be kept for at least 30 years.
What to Do Now
- Inventory every task your crews perform on painted or coated surfaces and sort each one into the three trigger-task tiers of Section 1532.1(d)(2).
- Commission personal air sampling on your most common trigger tasks so you can document actual exposures instead of living under the presumed levels.
- Rewrite the compliance program for the current PEL of 10 µg/m³, make it project-specific for any Caltrans or public works job, and calendar the six-month review.
- Build the 24-hour Cal/OSHA notification into your pre-job checklist and keep a copy of every notice sent.
- Set up blood lead testing with a clinic that knows the 10, 20, and 30 µg/dL triggers and can turn results around before the next sampling interval.
- Verify CDPH certification for every worker and supervisor on residential or public building projects and file the CDPH 8551 for abatement work.
