Pre-1978 Paint Disturbance: Stop and Assess

Purpose

If you are about to disturb paint in a house built before 1978 and you have not measured the area and checked your method, stop now: put the sander down, do not sweep or vacuum dry, close the door to the room, and get the occupants, above all any child under six or anyone pregnant, out of the space until this is resolved. Dry sanding a pre-1978 wall for ninety seconds puts lead dust on every horizontal surface in the room, and it goes home on your clothes.

This procedure guarantees one thing: nobody in the shop decides in the moment whether a paint-disturbing job is small enough to just do. The decision is made against measured square footage and a named method, before the tool starts, by someone who has checked both gates. The failure it prevents is the tech who did a good job on a small patch, brushed the debris into a dustpan, and left a family with a contaminated floor and the shop with a violation it cannot argue its way out of because the sander is in the photographs.

Scope

Covers the arrival assessment and stop decision for any repair, renovation or painting the shop performs for compensation in target housing built before 1978 or in a child-occupied facility, where painted, varnished or coated surfaces will be disturbed.

Explicitly not covered:

• Performing regulated lead-safe work. That is done only by a firm certified under 40 CFR Part 745 Subpart E with a certified renovator on site, working to that rule's containment, work-practice and cleaning-verification requirements. This SOP ends at the handoff.
• Deciding whether paint contains lead. Only an EPA-recognized test kit used by a certified renovator, paint chip sampling by an accredited lab, or an inspection by a certified inspector or risk assessor answers that. Absent one of those, the paint is presumed to be lead-based and this SOP runs.
• Post-1977 housing, which is outside the rule, though the dust and silica controls in the shop's other procedures still apply.
• Employee exposure monitoring and medical surveillance, which are the shop's obligations under 29 CFR 1926.62 and belong to the owner, not the tech on the ladder.

Roles and responsibilities

The procedure

1. Establish the year built before the tool comes out, and default to presumed lead if it is unknown. The office should have it, but verify: county assessor record, the customer's own statement, or the deed. Acceptance: a year written on the ticket with its source. Wrong looks like guessing from the style of the house, which misreads renovated pre-war homes constantly. Stop rule: year unknown or contested, treat it as pre-1978 and run this SOP anyway. There is no penalty for treating a 1985 house carefully and there is a large one for the reverse.

2. Confirm the property is target housing before applying the rule, because two carve-outs exist. Target housing under the rule is pre-1978 housing other than a zero-bedroom dwelling, and other than housing for the elderly or persons with disabilities unless a child under six resides or is expected to reside there. Acceptance: a one-line note, for example "1952 three-bedroom single family, occupied by a family with a four-year-old." Wrong looks like assuming a senior apartment is exempt without asking about grandchildren living there. Stop rule: unclear, call the lead rather than resolving a carve-out from the truck.

3. Measure the surface you will actually disturb, room by room for interior work and in total for exterior work. The minor repair and maintenance exemption at 40 CFR 745.82 stops applying above 6 sq ft of disturbed painted surface per room for interior activities, or 20 sq ft for exterior activities. Measure the whole disturbed area, not the defect: a patch plus its feathered and sanded halo is the number. Acceptance: a written figure per room in square feet with the dimensions it came from. Wrong looks like measuring the hole and forgetting the sanding halo, which routinely doubles the area. Stop rule: over the threshold, stop and go to step 6.

4. Check your planned method against the prohibited practices, because method voids the exemption regardless of area. The rule prohibits open-flame burning or torching, operating a heat gun at 1,100 degrees F or above, and machine sanding, grinding, planing, needle gunning or abrasive blasting with power tools not fitted with a shroud and HEPA vacuum attachment. Window replacement and demolition of painted surface areas also fall outside the minor repair exemption on their face. Acceptance: your method written down and checked against that list. Wrong looks like a 3 sq ft patch treated as exempt while a bare random-orbit sander sits on the floor, which it is not. Stop rule: any prohibited practice in the plan, either change the method or go to step 6.

5. If the work stays inside both gates, still work wet and clean wet. Score before pulling trim, mist surfaces before scraping, hand-sand with a wet sponge or a shrouded sander on a HEPA vacuum, put down plastic, and clean with wet methods and a HEPA vacuum only. Acceptance: no visible dust bloom during the work, no dry sweeping at any point, debris bagged rather than dustpanned. Wrong looks like a shop vac without a HEPA filter, which discharges the fine fraction back into the room air, which is the fraction that matters. Hazard: lead dust is an inhalation and ingestion hazard, so nobody eats, drinks or smokes in the work area, hands and face get washed before the truck, and work clothes go home in a bag rather than worn, per the hygiene and change requirements in 29 CFR 1926.62.

6. When either gate is crossed, stop, contain what you already disturbed, and hand it off. Stop cutting or sanding immediately, mist and wet-wipe anything already loosened, bag it, HEPA vacuum the area, and close the room. Then call the lead with the measured figure and the method. Acceptance: work stopped, debris contained wet, occupants out of the room, one phone call made from the site. Wrong looks like finishing the patch and mentioning it later, which converts a scheduling problem into a violation with a witness. Stop rule: the tech does not resume, negotiate or reduce the scope on the spot. That is the lead's call, and the lead's options are a certified renovator, a referral, or declining the work.

7. When the shop proceeds as a certified firm, the paperwork starts before the work does. The Renovate Right pamphlet goes to the owner and to occupants before the job begins, with a written acknowledgment, and the rule expects that within a reasonable window ahead of the start rather than months earlier. Acceptance: signed acknowledgment in hand before any surface is disturbed. Wrong looks like handing the pamphlet over at the end with the invoice. Stop rule: no acknowledgment, no start, and the certified renovator on site owns that call rather than the office.

The record this produces

The rule requires the certifying firm to keep its renovation records, and 40 CFR 745.86 sets that retention at three years from completion. The shop's own file needs more than the minimum, because the useful question later is why a job was or was not treated as regulated:

• Year built and its source, and the target-housing determination including which carve-out was considered.
• Measured disturbed area per room, with the dimensions, and the exterior total if applicable.
• Planned method, named specifically enough to check against the prohibited-practice list.
• The decision and who made it: proceeded under the minor repair exemption, proceeded as a certified firm, referred out, or declined.
• Renovate Right acknowledgment, signed and dated, where the shop proceeded as a certified firm.
• Photographs of the area before and after, which is the only cheap evidence of how much surface was actually disturbed.

Office files it against the property, not just the job, because the next call to that address starts from the same determination.

Worked pass: hallway ceiling patch, 1952 single family

Step 1: assessor record says 1952, written on the ticket by the office. Step 2: three-bedroom single family, occupied, a four-year-old in the house. Target housing, no carve-out, and the child under six is exactly who the rule exists for.

Step 3: the water-stained ceiling patch measures 18 in by 30 in, which is 540 sq in, or 3.75 sq ft. But the tech is going to feather and sand about 3 in past the patch on all sides, making the disturbed area 24 in by 36 in, or 864 sq in, which is 6.0 sq ft. Sitting exactly at the interior per-room threshold, with no margin, which is already a call to the lead in a well-run shop.

Step 4 is where it failed, and it failed on method rather than on area. The plan was a random-orbit sander to flatten the compound, and that sander has no shroud and no HEPA vacuum attached. That is a prohibited practice under the rule, and a prohibited practice voids the minor repair exemption whatever the square footage, so even the original 3.75 sq ft version of this job would not have qualified. Stop rule fired at step 4 before anything was cut.

Then the scope grew, which is the ordinary way these jobs cross the line. Standing there, the customer asked about the peeling casing on the hall window: roughly 16 linear ft of casing at 3.5 in wide, which is 16 times 0.29 ft, about 4.67 sq ft. Added to the ceiling's 6.0 sq ft, that is 10.67 sq ft in that one room, roughly 1.8 times the 6 sq ft per-room interior threshold. Two independent reasons to stop.

Step 6 ran as written: nothing had been sanded, so containment was light. The tech misted and wiped the two spots already scraped by hand, bagged the debris, HEPA vacuumed a strip of floor, closed the hall door, and called the lead from the porch. The lead's call was to schedule the shop's certified renovator for both items on one visit rather than send the tech back for the ceiling alone, which would have been the same job twice.

Step 7 then ran on that visit: Renovate Right delivered and acknowledged in writing before any surface was touched.

Checked back against the general section: step 4 states that method voids the exemption regardless of area, and this pass proved it by stopping a job that was, on area alone, arguably inside the gate. Step 3 says measure the disturbed area rather than the defect, and the 3.75 to 6.0 sq ft difference between the patch and its halo is the whole reason the ceiling was borderline instead of comfortable.
