{"hq_id":"hq-p-chd-000093","name":"Convertible High Chair (Painted Wood/Metal with PVC Seat Pad)","category":{"primary":"children","secondary":"gear_transport","tags":["high chair","PVC","lead paint","phthalate","feeding"]},"product_tier":"CHD","overall_risk_level":"high","description":"Convertible high chairs used from infancy through toddlerhood (6 months to 5 years), featuring painted wood or metal frames with PVC-upholstered seat pads. Children sit in these chairs 3+ times daily for meals, with bare legs contacting PVC surfaces and hands/mouths touching painted surfaces. PVC seat pads contain phthalate plasticizers (DEHP, DINP) that migrate to skin on contact — accelerated by food spills and cleaning product residues. Painted surfaces on lower-cost models may contain lead, especially in imported products. The extended product lifespan (5+ years) means continued exposure as plasticizer content depletes and paint degrades.","synthesis":{"derived_risk_level":"moderate_to_high","synthesis_confidence":0.855,"synthesis_method":"compound_composition","context_used":"human_infant","context_source":"product_users","exposure_modifier":1.208,"vulnerability_escalated":true,"escalation_reason":"CHD tier product","compounds_resolved":4,"compounds_total":4,"synthesis_date":"2026-03-27","synthesis_version":"1.0.0"},"hazard_summary":{"sensitive_populations":"infants, children","overall_risk":"high","primary_concerns":["PVC seat pads leach phthalate plasticizers through skin contact; painted surfaces risk lead contamination (especially imports); food residue + cleaning chemicals accelerate migration; mouthing of tray edges by teething babies"],"exposure_routes":"Dermal contact: bare legs and arms on PVC seat pad 45-90 min/day; Hand-to-mouth: touching painted surfaces then eating; Ingestion of paint chips from teething/mouthing the chair tray and rails"},"exposure":{"users":["infant","child"],"routes":["dermal","oral"],"contact_types":["skin_prolonged","oral_direct"],"duration":"hours","frequency":"daily","scenarios":["Oral/ingestion exposure during use of Convertible High Chair (Painted Wood/Metal with PVC Seat Pad)","Dermal contact during handling of Convertible High Chair (Painted Wood/Metal with PVC Seat Pad) (hours contact)","Incidental mouthing or hand-to-mouth transfer by children"],"notes":"Exposure to Convertible High Chair (Painted Wood/Metal with PVC Seat Pad) occurs via dermal, oral.
