Nail salon tool tray and workstation evidence for AI

An overhead image can show that a tray changed.

NAICS 812113 · Nail Salons

An overhead image can show that a tray changed. It may leave unresolved which items were placed there and who marked the station ready. OSHA’s nail salon resources cover worker health and safety topics. A nail salon can use labeled training props to document observable hand movements without recording a service. OSHA nail salon resources

Stage two trays with different inert tool IDs and a workstation sign-off card. Show a change from the first tray to the second. Add a control case where the card is present but the identifying tray feature is off camera. Ask the model which tray it can identify and what the image supports about the sequence.

Keep live client services, faces, chemicals and appointment records out. Use adult participants and clear the location and footage rights.

Describe a staged nail workstation sample

Original Fiund exercise

A ready card does not identify an off-camera tray

Two trays of inert blunt props and original station cards support a staged overhead task. No client service, chemical, face or actual hygiene procedure is recorded.

Fictional records supplied to the evaluator
RecordSourceWhat it records
NS1Practice tray registerTray A has square marker and tool IDs A1/A2. Tray B has circle marker and B1/B2.
NS2Visible change clipSquare tray A removed; circle tray B placed in view. Reviewer signs card for station S after the clip.
NS3Control imageReady card at station S2 visible, but tray marker and tool IDs outside frame. No S2 review record linked to the image.

Question for the model

Which tray change is observable, and does S2's ready card establish its tray identity or an independently verified station state?

Show the reference answer and checks

NS1 and NS2 support the observed A-to-B tray change through the square and circle markers, with a separate station-S reviewer record. NS3 shows a card at S2 but hides the evidence needed to identify its tray. The card's presence alone does not supply a linked review or the missing visual identity. Report sequence, tray and sign-off as distinct fields without declaring sanitation or readiness from an unlinked prop.

  • Inferring an unseen tray from a nearby ready card.
  • Transferring station S's sign-off to similarly labeled S2.

Fields to preserve

Tray marker and tool IDs
Defines visible identity.
Station and event sequence
Links the swap to its location.
Reviewer-card relationship
Separates displayed labels from verified authorization.

Test another case

Show B's marker clearly at S2 but leave sign-off unlinked. Require identity to resolve while the review status remains open.

Use consenting adults, inert props and cleared footage. Exclude live services, clients, faces, chemicals and appointment records.
