Primary hazard is inhalation of aerosolized solvent vapors. Xylene and toluene are CNS depressants and neurotoxicants with OSHA PELs of 100 ppm TWA. Some formulations historically contained methylene chloride (dichloromethane, metabolized to CO — cardiac arrest risk, IARC 2A), now being phased out in consumer products by EPA TSCA action (2024). Highly flammable. Spray painting without respiratory protection generates peak exposures 5-50x above occupational limits.","synthesis":{"derived_risk_level":"low","synthesis_confidence":0.586,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":1.1,"vulnerability_escalated":true,"escalation_reason":"Child exposure group","compounds_resolved":4,"compounds_total":4,"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]).
