How to Keep Lead From Coming Home on You
Why this matters
Lead dust from an old-paint job does not stay on the job. It rides home in the seams of coveralls, in boot treads, on the steering wheel and in your hair, and it lands on the floor of a house where a toddler crawls and puts everything in their mouth. Take-home lead is documented well enough that Congress ordered NIOSH to study it in the early 1990s, and the cases keep appearing: a child with an elevated blood lead level whose only source turns out to be a parent's work. CDC says there is no known safe blood lead level in children and uses 3.5 micrograms per deciliter as its reference value, a number a few days of tracked-in dust can reach. Respirators protect your lungs. This procedure protects everyone who lives with you.
The path lead takes
Lead leaves a job four ways: on your skin and hair, on your clothes and boots, on things you carry (tools, phone, lunch cooler), and on the surfaces of the truck. Each step below closes one leg of that path, in the order the dust actually travels. Skip one and the steps after it are fighting dust that has already moved.

The line that matters most is the one between the truck bed and the cab. Everything left of it is treated as contaminated, everything right of it is kept clean, and the change happens at that line.
Step 1: Decide it is a lead day before you load the truck
If the house was built before 1978 and the work will disturb paint, or a test has shown lead-based paint on what you will touch, it is a lead day. Make the call at the shop, not on site.
Why: the whole procedure depends on kit you have to carry: a change of clothes, coveralls, a lidded bin, bags, soap, water and paper towels. A tech who finds out at noon that the trim is lead has none of it and drives home in what they worked in. The occupant side of the same decision is the EPA renovation rule. See related: EPA Lead RRP Rule for Contractors.
Step 2: Dress for the job in clothes that never go home
Wear disposable or launderable coveralls over work clothes, or dedicated work clothes that live at the shop. Work boots for lead days stay in the bin in the truck bed, or wear disposable shoe covers over them. Tie long hair back and wear a cap or a hood.
Why: fabric holds fine dust in the weave and releases it every time it flexes, which means in the cab, on a couch, and in the family washer. Boot treads are the largest single carrier into a house because they deposit dust on floors, which is exactly the surface a child touches. Under 29 CFR 1926.62(g), where employees are exposed above the PEL (or are presumed to be, before an exposure assessment), the employer provides protective clothing at no cost and handles the laundering. See related: Lead Exposure for the Worker, Not the Occupant.
Step 3: Nothing goes in your mouth in the work area
No eating, drinking, smoking, vaping, chewing gum or tobacco inside the work area, and no phone calls with the phone pressed to a dusty face. Keep the lunch cooler and the water jug in the cab, not on the tailgate.
Why: ingestion is a real route on a lead job. A cigarette held in dusty fingers delivers lead straight to the mouth, and smoking heats it on top of that. A phone handled with work gloves and then held to your face does the same thing more slowly. This is the step most often skipped because it costs nothing in the moment and the harm shows up weeks later on a blood test.
Step 4: Wash hands and face before every break
At every break and before you leave the work area, wash hands, forearms and face with soap and running water, and scrub under the nails. Set up a wash station at the work-area exit if the house has no sink you are allowed to use: a jug of warm water with a spigot, soap, paper towels and a catch bucket.
Why: washing has to happen before the hands touch food, the cab or the phone, or the wash only cleans dust you have already spread. Alcohol hand sanitizer does not remove lead dust; it leaves the dust on the skin and spreads it around. If running water truly is not available, use wipes made specifically for lead removal and wash properly at the next sink. Keep nails short; dust packs under them.
Step 5: Change at the line, before the cab
At the end of the day, at the truck bed:
- HEPA-vacuum the coveralls while still wearing them, or gently brush off visible debris outdoors. Never blow them off with compressed air or shake them; both put the dust back in the air at face height, and 1926.62 prohibits removing lead from clothing that way.
- Peel the coveralls off by rolling them inside-out, so the dirty face ends up inside. Bag disposables; put launderables in the lidded bin.
- Boots off into the bin, or shoe covers off into the bag, standing on a clean mat.
- Wash hands and face again, because steps 1 to 3 just put dust back on them.
- Put on street shoes and get in the cab.
Why: this is the step that keeps the cab clean, and the cab is the one place you go every day and never clean properly. A tech who changes at home has already carried a full day's dust through the truck.
Step 6: Keep the cab clean, and check it
No work gloves on the steering wheel, no tools that came out of the work area without being wiped or bagged, no boots in the footwell. HEPA-vacuum the cab floor and seats weekly on lead-job weeks and wipe the wheel, shifter and door handles with damp disposable wipes.
Why: dust in a cab is re-suspended every time a door shuts or the fan runs, so a dirty cab exposes you on the drive and exposes anyone else who rides in it, including a child on a weekend. A standard household vacuum blows the fine fraction straight back out of its exhaust; only a HEPA-filtered vacuum captures it.
Step 7: Launder separately, and never with the family wash
Work clothes and launderable coveralls go to the shop's laundering arrangement or a commercial laundry. Under 1926.62(g), when the employer launders lead-contaminated clothing, the laundry must be told in writing that it is contaminated, and the bag carries a warning label. They do not go in the household machine.
Why: a washer that runs work clothes then children's clothes transfers lead to the second load, and the lint trap and drum hold dust between cycles. An owner-operator with no laundry option should treat that as the problem to solve, not the routine to accept. If a one-off home wash cannot be avoided, run work clothes alone and then run an empty cycle before anything else goes in, and understand that this reduces carry-over rather than removing it.
Step 8: Shower before you pick up your kids
On a lead day, shower and wash your hair as soon as you get home, before hugging a child, sitting on furniture or starting dinner. Where the job can provide showers, use them there.
Why: hair and skin carry dust that steps 4 and 5 do not reach, and a child is picked up, held at face height and played with on the floor. This is the moment the whole procedure is for.
A worked example
A two-person crew is preparing the exterior of a 1931 house for paint: three days of hand-scraping and wet-sanding clapboards and trim, with a test showing lead-based paint on the siding and window trim. One tech, D., has a two-year-old at home.
The routine runs as above. The wash station sits at the corner of the containment by the driveway. The crew times it: the lunch wash takes about 4 minutes each, the end-of-day change at the truck bed about 10 minutes, so 4 plus 10, about 14 minutes of the day per person, go to keeping lead off the cab and out of the house.
On day 2, D. leaves the work area at lunch to pick up a part, skips the change, and drives 20 minutes in coveralls and work boots. Nobody notices. After the job, the shop wipe-samples the cab floor of D.'s truck as part of its own check: a single damp-wipe sample over one square foot of the driver's footwell, sent to a lab. It comes back at 85 micrograms per square foot (illustrative). The truck is not regulated by any dust-lead standard, but for scale, EPA's clearance level for floors inside homes (40 CFR 745), lowered in 2024, is 5 micrograms per square foot. The cab floor reads 17 times that home floor level, and D.'s boots and street shoes have both stood on it.
The fix is not a lecture. The shop HEPA-vacuums and wet-wipes the cab, replaces the floor mats, moves D.'s work boots permanently into the lidded bin, and adds the cab footwell to its weekly lead-week cleaning. A repeat wipe two weeks later, after another lead job run with the change at the line, comes back at 4 micrograms per square foot, under the home floor level. D. also asks the child's pediatrician about a blood lead test, which is the right call whenever a parent's work involves lead, regardless of what a cab sample says.
What the example teaches: a single skipped change on a single lunch run put more lead on the cab floor than three days of routine did. The routine holds only if it holds every time the tech crosses the line, including the trips nobody planned.
How to tell the routine is working
- Blood lead trends hold flat. A tech whose results climb while air sampling says the respirator is holding is taking lead in by mouth or carrying it home. See related: The Tech Whose Blood Lead Came Back High.
- The cab stays clean on inspection. No visible paint chips or dust on mats, pedals or seats, and an occasional wipe sample stays low.
- Nobody changes at home. If a tech's street clothes are in the truck bed bin rather than the cab, the line has moved to the wrong place.
