PTFE is stable up to 260C (500F); above this temperature it begins to decompose, releasing toxic fumes including PFIB, HF, TFE, and ultrafine PTFE particles. Normal cooking temperatures (150-200C) are safe. Overheating empty pans, using on high heat, or leaving pans unattended on burners can reach decomposition temperatures within minutes. Polymer fume fever causes flu-like symptoms; PTFE fumes are lethal to pet birds.","synthesis":{"derived_risk_level":"extreme","synthesis_confidence":0.746,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":1.075,"vulnerability_escalated":false,"escalation_reason":null,"compounds_resolved":1,"compounds_total":1,"synthesis_date":"2026-05-09","synthesis_version":"1.2.0","methodology_note":"exposure_modifier and adjusted_magnitude are computed from ALETHEIA-calibrated heuristics (route × duration × frequency multipliers, clamped to [0.5, 1.4]).
