The Lead-Safe Floor Work SOP
Purpose
Carry out floor sanding, painted trim removal and floor demolition in pre-1978 homes as work under the EPA Renovation, Repair and Painting rule (40 CFR Part 745, Subpart E), so that the dust a flooring crew makes does not leave lead behind for a child to swallow. Floor work is close to the worst case for lead: sanding turns a coating into fine dust, and the floor is exactly where small children play. The rule's requirements are not optional extras on these jobs, and the fines and the harm both land on the shop that skipped them. This SOP turns the rule into the steps a crew runs.
Scope
Covers flooring work for compensation in target housing, meaning housing built before 1978 with the rule's own exclusions, and in child-occupied facilities, where the work disturbs painted or coated surfaces: sanding or screening a floor finish, removing painted base, shoe or casing, undercutting painted jambs, and tearing out floors with coatings on them. The rules themselves, the exemptions and their conditions are in Lead-Safe Rules for Floor Work in Pre-1978 Homes. In states EPA has authorized to run their own program, that state's rule governs and may be stricter. Asbestos in old floors is a separate hazard handled by The Old Floor Removal and Disposal SOP.
Roles and the handoffs
| Role | Owns | Hands off |
|---|---|---|
| Estimator | Home age, what coated surfaces the job disturbs | The lead flag to the office at estimate |
| Office | Firm certification current, pamphlet delivered and acknowledged | The signed acknowledgment to the certified renovator |
| Certified renovator | Determination, containment, crew training, cleaning verification, the records | The completed checklist to the office at job close |
| Crew | Work practices, daily cleanup | Any breach of containment to the certified renovator at once |
The certified renovator is a named person on each job. Where the rule requires them on site, they are on site; nobody else signs the cleaning verification.
The procedure
Decide whether the rule applies, and write the decision down. Confirm the year built and the occupancy type, list every coated surface the job will disturb, and either presume those coatings contain lead or have them tested by a certified inspector or risk assessor, or by the certified renovator with an EPA-recognized test kit. The rule's minor repair and maintenance exemption reaches only small areas per room and is lost if the work uses a prohibited practice or demolishes painted surfaces, so sanding a whole floor is far outside it. Acceptance: a written determination per surface, presumed or tested with the result. Wrong looks like "only a few boards, so it doesn't count" with a sander on the truck. Stop rule: no determination, no work on coated surfaces. Hazard: no scraping, sanding or cutting to "check" a coating before the determination.
Confirm the firm and the people. The firm's RRP certification is current, a certified renovator is assigned by name, and every crew member who will do the work has been trained by that renovator in the practices they will use, or is certified. Acceptance: certification dates checked and recorded, training recorded with names. Wrong looks like a new hire sent to pull base with no training. Stop rule: an expired firm certification stops the job before it starts. Hazard: none at this step.
Deliver the pamphlet and get it acknowledged. Give the owner, and the adult occupant if different, the EPA Renovate Right pamphlet no more than 60 days before the work begins, and get a written acknowledgment of receipt, or a certificate of mailing at least seven days before work if it is mailed. Acceptance: signed acknowledgment in the file before day one. Wrong looks like the pamphlet handed over on start morning with no signature. Stop rule: no acknowledgment or proof of mailing, no start. Hazard: none.
Set up containment before any coating is disturbed. Post warning signs at the work area's entries; remove furniture and objects or cover them with plastic sheeting; close and cover the forced-air registers and returns in the work area with the system off; close windows and doors and cover doorways with plastic, with the entry door covered so the crew can pass while dust stays in; and cover the floors around the work area with taped-down plastic as the rule's containment provisions describe. Acceptance: signs up, every opening covered, entry flap in place, the certified renovator has checked it. Wrong looks like an uncovered return in the room being sanded. Stop rule: containment torn or opened during work stops the work until it is repaired. Hazard: plastic sheeting on floors is slippery; tape every edge and keep it out of stair runs.
Use only permitted work practices. No open-flame burning or torching, no heat gun at 1100 F or higher, and no sanding, grinding or power planing unless the machine has a shroud or containment system with HEPA vacuum extraction collecting the dust at the point it is made, run so that no dust escapes it. A standard drum sander with a cloth bag does not by itself meet that description. Remove painted trim by scoring the paint line and prying, with no dry sanding of painted trim. Acceptance: every tool on site is either non-powered or meets the HEPA-shroud condition. Wrong looks like visible dust leaving a sander. Stop rule: visible dust escaping a machine stops that machine. Hazard: lead dust is an ingestion and inhalation hazard, so the crew wears respirators under the shop's program wherever OSHA 29 CFR 1926.62, which governs employee lead exposure separately from the RRP rule, calls for them on that task, and eats, drinks and smokes only outside the work area after washing.
Clean up and contain waste every day. At the end of each day, collect debris and chips, HEPA-vacuum the work area, and seal waste in heavy plastic bags or sheeting before it leaves the area. Carry waste out through the entry flap and transport it covered. Acceptance: no visible dust or debris in the work area overnight, waste sealed. Wrong looks like a broom in the work area; dry sweeping spreads the dust. Stop rule: dust tracked outside containment is cleaned with the HEPA vacuum and wet wipes before the crew leaves. Hazard: crew remove or HEPA-vacuum disposable coveralls and shoe covers before leaving the area.
Clean the work area in the rule's order. When the work is done, mist and fold plastic dirty side in, then clean walls from the top down by HEPA vacuum or wet wipe, HEPA-vacuum every remaining surface and object, wet wipe them, and wet mop hard floors with a method that keeps rinse water separate from wash water. Acceptance: every surface in the work area cleaned in that order. Wrong looks like mopping before vacuuming, which turns dust into a film. Stop rule: none at this step; the next step tests it. Hazard: none new; on a refinish, sequence the job so this cleaning and the verification come before the finish coats, or the finish seals any dust left onto the floor.
Run cleaning verification. The certified renovator wipes each windowsill and the hard floor in the work area with wet disposable cleaning cloths, one cloth for each floor section of up to 40 square feet, and compares each cloth to the EPA cleaning verification card. Acceptance: every cloth matches or is lighter than the card. Wrong looks like a cloth darker than the card. Stop rule: re-clean that section and re-verify with a new cloth; if it fails again, re-clean, wait one hour or until the surface is dry, whichever is longer, and wipe with a dry electrostatic cloth as the rule describes, then record that the section is done. Only after every section passes do the register and return covers come off, with the filter changed and the system restarted and confirmed running. Hazard: none beyond the containment still in place.
Close the records. File the determination, test results, firm and renovator certification, training records, pamphlet acknowledgment, and the work practices checklist with verification results, signed by the certified renovator. Keep them three years after the work ends. Acceptance: complete set in the job file. Wrong looks like a verification done and never written down. Stop rule: the job is not invoiced closed until the file is complete. Hazard: none.
The record this produces
The full RRP file described in step 9, plus the photo record of containment. It is read by the office at close, by an EPA or state inspector if the firm is audited, and by the shop itself if a family later asks what was done in that house. The checklist is the proof that the practices were followed, because the dust they controlled is gone.
Worked pass: oak refinish and new base in a 1956 house
Living room and dining room, about 380 square feet of red oak to sand and finish, painted base and shoe to replace. A family with a four-year-old.
Step 1: the house is 1956 target housing. The certified renovator presumed lead in both the base paint and the old floor finish rather than testing, and wrote that down. Step 2: firm certification current, renovator named, two crew trained on the job and recorded. Step 3: pamphlet handed to the owner nine days before start, acknowledgment signed.
Step 4: signs at both entries, furniture out, two registers and one return covered with the system off, kitchen and hall doorways sheeted, the hall doorway as the entry flap, plastic taped on the hall floor beyond it.
Step 5: the base came off by scoring and prying, bagged at the wall. The floor was sanded with a drum sander and edger fitted with shrouds and HEPA extraction, and one stretch near the hearth was hand-scraped. No dust was seen escaping. Step 6 ran each evening.
Step 7 ran after sanding and before any finish went down.
Step 8 failed its acceptance on one section. The living room, about 230 square feet, needed six cloths and the dining room, about 150, needed four, plus three sills. One living room cloth, the section along the hearth where the hand-scraping was done, came out darker than the card. The stop rule triggered: that section was re-cleaned and re-verified with a new cloth, which matched the card. Every other cloth passed first time.
The finish coats went on over a verified-clean floor, the new primed base went on after them, and step 9 closed the file with the hearth section's two wipes both recorded.
