This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

photo of the control in use per silica task + GPS + Table 1 checklist + written-plan status + tiered findings routed to the competent person

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

• respiratory protection per the site exposure control plan (N95/half-mask)
• tablet/clipboard with the 1926.1153 Table 1 checklist
• camera
• note on the written exposure control plan + fit-test/medical-clearance references
• flashlight

Steps

1. 1. Check in with the competent person; confirm a written exposure control plan exists and list the silica-generating tasks on site (cutting/grinding/drilling/chipping concrete, masonry, or stone). Observe-and-document only.
2. 2. Match each task to OSHA Table 1 and photograph whether the specified engineering control is in use, integrated water delivery (wet cutting) or a dust-collection/HEPA shroud.
3. 3. Verify respiratory protection matches the Table 1 requirement for the task and duration (e.g., N95 / half-mask APF-10) and that workers are wearing it; note any fit-test/medical-clearance the plan references.
4. 4. Check housekeeping: confirm NO dry sweeping or compressed-air cleaning of settled dust, wet methods or a HEPA vacuum must be used.
5. 5. Record the exposure zone: signage, who is inside the dust zone, and whether unprotected workers or bystanders are exposed.
6. 6. Tier each finding against the Table 1 requirement (stop-work / correct-before-proceed / monitor) and name the responsible competent person.
7. 7. Enter photos, GPS/address, the Table 1 checklist, plan status, and the tiered findings; sign. Route stop-work items to the competent person and any suspected exceedance to an industrial hygienist.

What counts as done

• Photos of each silica-generating task showing the engineering control (water delivery or dust-collection/HEPA) in use or absent
• GPS / address confirm
• OSHA Table 1 task/control checklist with respiratory-protection match recorded
• Written exposure control plan presence + housekeeping method noted
• Tiered findings list (stop-work / correct-before-proceed / monitor) with the responsible competent person named

Proof is measured against these, not judged by taste.
