Lead Awareness on Renovation Work

Hazards: Lead inhalation from sanding, cutting, burning and blasting paint · Lead ingestion from hand-to-mouth contact at breaks · Take-home lead on clothing and boots · Nervous system, kidney and reproductive effects

Why it matters

Lead work got much safer and is still not safe. NIOSH reports the share of workers at or above a blood lead level of 25 micrograms per deciliter fell 81 percent, from 14 per 100,000 workers in 1994 to fewer than 3 in 2019 — with construction still one of the four industries where it happens. And it does not stop at the gate: CDC has documented New York State children with elevated blood lead traced to renovation work in their own homes (MMWR 2009;58(3)).

Key points

  • Some tasks are presumed over the limit before anyone samples. Manual scraping and sanding, heat gun work and power tool cleaning on lead coatings are presumed above the 50 ug/m³ PEL; blasting, welding, cutting and torch burning on lead paint are presumed at fifty times it. Presumed means protected on the first shift — respirators, protective clothing, change areas, washing and blood lead monitoring — not when the lab report comes back.
  • Nothing goes home. Work clothing stays on site, and separate storage keeps street clothes clean. Whoever is waiting at home did not sign up for this job.
  • Pre-1978 housing is a second rulebook. EPA's RRP rule applies on top of OSHA: certified firm, certified renovator on the job, pamphlet to the owner, containment, cleaning verification, records kept three years.
  • No torching, no hot heat guns, no bare grinders. Open-flame burning of painted surfaces is prohibited, heat guns are capped below 1,100 °F, and high-speed removal equipment needs a shroud with HEPA collection.
  • Blood lead is the scoreboard. OSHA pulls a worker off lead work at 50 ug/dL; NIOSH's reference level for adults is 5. A climbing number means the controls are not working, whatever the paperwork says.

Do / Don't

Do

  • Ask the age of the structure and whether the paint was tested.
  • Hook the grinder or sander to a HEPA shroud first.
  • Wash hands and face before every break, not just lunch.
  • Change and bag your work clothes on site, every day.

Don't

  • Torch, burn off or open-flame strip painted surfaces.
  • Dry sweep chips and dust, or blow them off with air.
  • Eat, drink, vape or chew anywhere near the work area.
  • Wear the boots and coveralls into the truck or the house.

Quick site check

  • What year was this built, and is it target housing under the RRP rule?
  • Which task today is on the OSHA presumed-exposure list?
  • Where exactly do we wash, change and store street clothes?
  • Who has had a blood lead test, and when was the last one?
Discussion — ask the crew
  1. What year was this built, and has anyone tested the paint we are about to disturb?
  2. Which task today is a torch, heat gun, grinder or needle gun on painted steel?
  3. Where do we wash before we eat here, and is it actually usable?
  4. Who drives home in the clothes and boots they wore all day, and who is waiting at home?

Frequently asked questions

29 CFR 1926.62(c)(1) sets a permissible exposure limit of 50 micrograms of lead per cubic meter of air averaged over 8 hours. If someone works more than 8 hours in a day, (c)(2) reduces the allowable exposure: 400 divided by the hours worked. The action level, defined in paragraph (b) and measured without regard to respirator use, is 30 micrograms per cubic meter as an 8-hour TWA.

1926.62(d)(2) lists them, and until an exposure assessment documents otherwise you must treat the worker as exposed and provide interim protection. Presumed above the PEL but not more than ten times it: manual demolition of structures, manual scraping, manual sanding, heat gun applications and power tool cleaning with dust collection, where lead coatings or paint are present; plus spray painting with lead paint. Presumed above 500 ug/m3: using lead-containing mortar, lead burning, rivet busting, power tool cleaning without dust collection, cleanup where dry expendable abrasives are used, and abrasive blasting enclosure movement and removal. Presumed above 2,500 ug/m3, which is fifty times the PEL: abrasive blasting, welding, cutting and torch burning on lead-coated structures.

Under 1926.62(d)(2)(v), until the exposure assessment is done the employer provides appropriate respiratory protection, protective work clothing and equipment, change areas, hand washing facilities, biological monitoring for blood lead and zinc protoporphyrin, and training. It is not a paperwork step: it is the full package, applied on the presumption that the task is over the limit.

1926.62(h): all surfaces are kept as free as practicable of lead accumulations. Cleanup is by vacuuming or other methods that minimize the chance of lead becoming airborne. Shoveling, dry or wet sweeping and brushing may be used only where vacuuming or equally effective methods have been tried and found not to work. Vacuums must have HEPA filters and be used and emptied so lead does not re-enter the workplace. Compressed air may not be used to remove lead from any surface unless it is used with a ventilation system designed to capture the airborne dust it creates.

Lead dust that leaves the job on clothing, boots, tools and vehicle seats and ends up on the floor at home. 1926.62(i)(2)(iii) is blunt about it: employees may not leave the workplace wearing any protective clothing or equipment required during the shift. Above the PEL, (i)(2) requires clean change areas with separate storage for work clothing and street clothes so the two never touch, and (i)(3) requires showers where feasible. CDC's MMWR reported cases of New York State children with elevated blood lead levels traced to renovation, repair and painting activities in their homes during 2006 and 2007 (MMWR 2009;58(3)).

1926.62(k)(1)(i) requires the employer to remove an employee from work having an exposure at or above the action level on each occasion that a periodic and a follow-up blood test show a blood lead level at or above 50 micrograms per deciliter. That is the legal trigger, and it is far above what health agencies consider elevated: in 2015 NIOSH designated 5 micrograms per deciliter as the reference blood lead level for adults.

It is a separate rule with a separate reach. 40 CFR part 745 subpart E applies to renovation, repair and painting done for compensation in target housing and child-occupied facilities built before 1978. The firm must be EPA-certified, must assign a certified renovator to the job and ensure everyone else has been trained by one (745.89(d)), and must give the owner EPA's lead hazard information pamphlet no more than 60 days before the work starts (745.84(a)). Work practices under 745.85(a) include posted signs, containment with protective sheeting extending 6 feet beyond interior surfaces and ground cover 10 feet beyond an exterior perimeter, covered waste chutes, and cleaning verification. Records are kept 3 years (745.86(a)).

40 CFR 745.85(a)(3): open-flame burning or torching of painted surfaces is prohibited. Operating a heat gun on painted surfaces is permitted only at temperatures below 1,100 degrees Fahrenheit. High-speed paint removal equipment - sanders, grinders, planers and similar machines - may only be used with a shroud and HEPA vacuum collection. A minor repair and maintenance exemption exists for work disturbing 6 square feet or less of painted surface per room indoors, or 20 square feet or less outdoors (745.83), but it does not cover work using any of those prohibited practices.
