Fiberglass acoustic ceiling tiles: synthetic vitreous fibers classified IARC Group 3 (not classifiable as carcinogenic), but fiber release during installation, maintenance, or disturbance can cause skin, eye, and respiratory irritation. Recycled PET acoustic panels (FilzFelt, BuzziSpace): made from recycled plastic bottles — no fiber release, no formaldehyde, increasingly popular.","synthesis":{"derived_risk_level":"severe","synthesis_confidence":0.757,"synthesis_method":"compound_composition","context_used":"human_adult","context_source":"product_users","exposure_modifier":0.935,"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]).
