29 CFR 1926.62: OSHA Lead Standard for Construction Work

29 CFR 1926.62, the OSHA lead standard for construction, requires employers to keep worker exposure to airborne lead below 50 micrograms per cubic meter of air, averaged over an eight-hour shift, and to build a program of monitoring, medical checks, controls, and training around that limit. It applies to any construction task where lead may be released, from full demolition down to a plumbing repair that disturbs an old painted joint. Two numbers anchor the rule: an action level of 30 µg/m³ that triggers medical surveillance and ongoing monitoring, and a permissible exposure limit (PEL) of 50 µg/m³ that no worker may exceed.¹

When the Standard Applies

The regulation covers all construction work where an employee may be occupationally exposed to lead.¹ The language is deliberately broad. If a task has any potential to release lead into the air or generate lead-contaminated dust, the rule kicks in. That includes:

Demolition or salvage of structures with lead paint, piping, or coatings.
Removal, encapsulation, or stripping of lead-based coatings.
New construction, alteration, or repair of surfaces with lead finishes.
Renovation and routine maintenance that disturbs painted surfaces, plumbing joints, or structural components containing lead.
Site preparation involving lead-contaminated soil or debris.

The employer, not the worker, has to identify lead before a job starts. A small task like replacing a section of old pipe or drilling conduit through a painted wall can pull in the full set of requirements if it disturbs lead-containing material. On multi-contractor sites, OSHA can cite more than one employer for the same hazard: the contractor whose work created it, any contractor whose workers were exposed, and the general contractor with supervisory authority over the site.² A general contractor cannot treat lead as somebody else’s problem.

Exposure Limits and Air Monitoring

Both thresholds are measured as eight-hour time-weighted averages, and both are calculated without regard to whether the worker is wearing a respirator. The action level (30 µg/m³) triggers medical surveillance, periodic air monitoring, and employee notification. The PEL (50 µg/m³) is the ceiling no worker may cross on any shift.

Employers have to conduct an initial exposure assessment using personal air samples that represent a full shift for each job classification. Previous monitoring, employee reports, and the specific tasks all feed into it. Any change in equipment, process, or crew means a new assessment. After every round of sampling, the employer must notify each affected worker of the results within five working days, in writing or by posting them where employees can see them.¹ Notification is required whether the results are high or low.

Interim Protection Before the Assessment Is Done

Some tasks are treated as overexposures by default until air sampling proves otherwise. The standard sorts them into three tiers by assumed airborne concentration:³

Assumed above the PEL, up to 500 µg/m³: manual demolition of structures like drywall, manual scraping and sanding, heat gun use, power tool cleaning with dust collection, and spray painting with lead paint.
Assumed above 500 µg/m³: lead burning, work with lead-containing mortar, rivet busting, power tool cleaning without dust collection, dry abrasive cleanup, and moving or removing abrasive blasting enclosures.
Assumed above 2,500 µg/m³: abrasive blasting, welding, cutting, and torch burning on lead-coated surfaces.

For each tier, the employer has to provide the matching level of respiratory protection, protective clothing, change areas, hand washing facilities, biological monitoring, and training. The interim measures stay in place until documented sampling shows actual exposure. Any other task the employer has reason to believe could exceed the PEL also gets interim protection.

The Written Compliance Program

Before any project where exposure could reach the PEL, the employer must establish a written compliance program tailored to that specific job and updated at least annually.¹ A generic safety manual will not do. At minimum the plan must describe each lead-emitting activity and its controls, the compliance methods that will bring exposure below the PEL, the technologies considered, air monitoring data identifying emission sources, an implementation schedule backed by purchase orders and contracts, and how contractors on a shared site will coordinate and inform each other’s employees.

A competent person has to inspect the site, materials, and equipment frequently. The written program must be available at the worksite for any affected employee to review and copy, and produced to OSHA on request.

Controls and Protective Equipment

The standard imposes a hierarchy. Engineering and work practice controls come first: local exhaust ventilation, shrouded tools, wet methods, and HEPA-filtered vacuuming. Every feasible engineering control has to be in place before the employer relies on respirators, even if those controls alone will not bring exposure below the PEL.¹ Respirators cover whatever gap remains.

When respirators are needed, the employer pays for them and runs a full respiratory protection program: fit testing, medical clearance, respirator selection matched to the exposure, and training on use and care. Protective clothing keeps lead off skin and out of workers’ homes. Contaminated clothing must be stored separately from personal items and cleaned or disposed of properly, and workers cannot leave the site wearing it.

Housekeeping and Hygiene

Lead dust migrates, and housekeeping is a compliance requirement rather than a suggestion. Surfaces must be kept as free as practicable of lead accumulations, and cleanup is done with HEPA-filtered vacuums. Compressed air can only be used with a ventilation system designed to capture the airborne dust it stirs up.¹

Change rooms with separate storage for street clothes and work clothes are required. Where feasible, showers must be provided when exposures exceed the PEL. Handwashing stations are required in all cases, and workers must wash before eating, drinking, smoking, or applying cosmetics.

In work areas where airborne lead exceeds the PEL, three activities are flatly prohibited: eating or drinking, using tobacco products, and applying cosmetics.¹ Workers may not enter lunchrooms or eating areas in protective clothing unless surface lead dust has first been removed by vacuuming or an equivalent method. These rules target ingestion, the exposure route that gets overlooked most often.

Medical Surveillance and Removal Protection

Any employee exposed at or above the action level on any single day must be offered initial medical surveillance. For workers exposed at or above the action level for more than 30 days in any 12-month period, the employer must run an ongoing medical surveillance program that includes blood lead level and zinc protoporphyrin testing.¹ Blood tests happen at least every two months for the first six months, then every six months.

When a periodic blood test and a follow-up test both show a blood lead level at or above 50 µg/dl, the employer has to remove that worker from any assignment with lead exposure at or above the action level.¹ The employee can return only after two consecutive blood tests come back below 40 µg/dl.

During removal, the employer must provide medical removal protection benefits for up to 18 months: the worker keeps total normal earnings, seniority, and all other employment rights as if the removal never happened.¹ Pay cuts and demotions tied to a high blood lead result are not allowed. The employer can condition these benefits on the employee’s continued participation in the surveillance program.

If the employer picks the physician for a medical exam, the worker has the right to a second opinion from a physician of their own choosing, and the employer must notify them of that right after every exam.¹ If the two disagree, a third physician resolves it, and the employer pays.

Training, Observation, and Records

Employers must train every employee who may be exposed at or above the action level, and repeat that training at least annually.¹ Training covers the health effects of lead, the compliance program, proper use of protective equipment, and the worker’s rights under the standard. OSHA compliance officers routinely ask employees what they were taught; vague answers produce citations.

Employees can observe any exposure monitoring done on the site, receive an explanation of the sampling methods, watch each step, and take or receive copies of the results.¹ Workers and their representatives can also access exposure monitoring records and medical records maintained under the standard.

Retention periods are long because lead-related illness often shows up years after the exposure ends. Exposure monitoring records and objective data must be kept for at least 30 years, and medical records for the duration of employment plus 30 years.¹

A Separate Rule Applies on Pre-1978 Housing

OSHA’s lead standard protects workers. On housing and child-occupied facilities built before 1978, EPA’s Renovation, Repair and Painting (RRP) rule separately protects the people who live and use the building. Any firm paid to disturb paint on those properties must be EPA-certified and assign a certified renovator to the project.⁴ The rule reaches remodeling, plumbing, electrical work, carpentry, window replacement, and painting preparation, with narrow exemptions for post-1978 housing, minor repairs under six square feet inside a room or 20 square feet outside, and properties certified lead-free.⁵ Meeting 1926.62 does not satisfy RRP, and a crew that monitors air perfectly can still be cited by EPA for failing to contain dust or distribute the required lead hazard information.

Penalties for Non-Compliance

OSHA adjusts its penalty maximums for inflation each year. Effective January 2025:⁶

Serious violation: up to $16,550 per violation.
Other-than-serious violation: up to $16,550 per violation.
Willful or repeated violation: up to $165,514 per violation, with a minimum of $11,823.
Failure to abate: up to $16,550 per day past the abatement date.

Each violation counts separately. A single inspection that finds no air monitoring, no written program, inadequate respirators, and missing medical surveillance can produce several citations at once. Willful classifications turn up more often in lead cases than employers expect, because the requirements have been on the books and widely published for decades.
