Larasplayground 24 11 22 Spunk On My Seams Part -

| # | Observation | Evidence | |---|-------------|----------| | 5.1 Material Composition | The deposit is a mixture of vegetable oil (≈ 62 %), synthetic polymer binder (≈ 28 %), and trace food‑grade flavoring agents (≈ 10 %). | GC‑MS chromatograms matched soybean oil standards; FTIR showed ester peaks. | | 5.2 Source Identification | The majority of the oil originates from snack‑stand spillages (particularly from the on‑site “Fruit‑Blast” kiosk). | Interviews confirmed a recent change to a higher‑oil fruit‑smoothie recipe (introduced 18 Nov 2022). | | 5.3 Seams as Accumulation Zones | Seam geometry (V‑groove profile) creates a capillary action that traps liquid droplets, preventing runoff. | UV‑flashlight highlighted oil films concentrated in the groove; flat panels showed negligible residue. | | 5.4 Safety Impact | Slip‑resistance testing (ASTM D2047) showed a 30 % reduction in coefficient of friction on affected seams. | Measured µ = 0.45 (clean) vs µ = 0.31 (oil‑covered). | | 5.5 Material Degradation | No immediate structural degradation noted; however, prolonged exposure may cause plasticizer leaching and micro‑cracking at the joint interface. | Preliminary tensile tests after 6 weeks of simulated exposure show a 5 % loss in tensile strength. | | 5.6 Cleaning Effectiveness | Standard high‑pressure rinse (150 psi) removed only ≈ 40 % of the deposit; manual scrubbing with a pH‑neutral degreaser removed ≈ 85 %. | Cleaning logs and post‑clean swab analysis. |

| Priority | Action | Responsible Party | Target Completion | |----------|--------|-------------------|--------------------| | High | Install spill‑containment trays under the Fruit‑Blast kiosk and enforce a “no‑drink on equipment” policy. | Facilities Management & Food Vendor | 15 May 2026 | | High | Revise cleaning SOP: add a weekly oil‑specific degreasing step for all seams (use biodegradable citrus‑based degreaser). | Custodial Services | 31 May 2026 | | Medium | Seal seam grooves with a food‑grade silicone bead (UV‑resistant) to reduce capillary trapping. | Playground Contractor (SafePlay Inc.) | 30 Jun 2026 | | Medium | Conduct slip‑resistance re‑testing after each cleaning cycle for the next 3 months. | Safety Officer | Ongoing | | Low | Educate visitors via signage: “Please keep food & drinks off playground equipment.” | Marketing / Public Relations | 01 Jun 2026 | | Low | Monitor material condition: schedule a quarterly visual inspection and a bi‑annual tensile test of seam connectors. | Engineering Maintenance | Every 3 months | Preventing Future Issues :
