Legacy vinyl composition tile (VCT): pre-1980 VCT commonly contains asbestos — present in 30-50% of US schools built before 1980. AHERA requires management plans but NOT removal (encapsulation is acceptable). New luxury vinyl tile (LVT): contains phthalate plasticizers (DINP, DEHP) that migrate to dust — children's floor-level exposure is 2-4x adult. School carpet: accumulates allergens (dust mite, mold, pet dander from students' clothing), bacteria, and cleaning chemical residue — associated with increased asthma in students. Hard flooring with regular wet mopping provides the lowest allergen exposure.","synthesis":{"derived_risk_level":"severe","synthesis_confidence":0.82,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":1.265,"vulnerability_escalated":true,"escalation_reason":"CHD tier product","compounds_resolved":1,"compounds_total":1,"synthesis_date":"2026-03-27","synthesis_version":"1.0.0"},"hazard_summary":{"sensitive_populations":"all students (floor-level exposure), asthmatic children (carpet allergens), maintenance workers (asbestos VCT)","overall_risk":"moderate","primary_concerns":["Pre-1980 VCT asbestos in 30-50% of older US schools","LVT phthalate plasticizers migrate to classroom dust (children's exposure)","Carpet allergen accumulation linked to student asthma","Children's floor-level exposure 2-4x adult levels"],"exposure_routes":"Inhalation (dust, fibers); dermal (floor contact); oral (hand-to-mouth from floor dust)"},"exposure":{"routes":["inhalation","dermal","oral"],"contact_types":["inhalation","skin_prolonged","oral_direct"],"users":["child"],"duration":"hours","frequency":"daily","scenarios":["Children sitting on floor: direct contact with vinyl phthalate dust","Pre-1980 VCT: asbestos exposure during maintenance, damage, or removal","Carpet allergen accumulation: dust mite, mold, pet dander from students","LVT phthalate migration to classroom dust (children's floor-level exposure)"],"notes":"AHERA (Asbestos Hazard Emergency Response Act, 1986): schools must have asbestos management plans, inspect every 3 years, and manage in-place asbestos.

LVT phthalate exposure: children's hand-to-mouth behavior increases oral exposure from floor dust. FloorScore certification: tests for VOC emissions from flooring (formaldehyde, phthalates, others).
