居家氧氣安全的核心在於「防火」。氧氣本身雖不可燃，但具強烈助燃性（Combustion-supporting），能大幅降低物質燃點並加快燃燒速度。在氧氣使用環境中，任何火源或火花都可能導致災難性後果。NCLEX 考試中，安全優先級（Priority）遵循 ABC 與安全原則，嚴禁吸菸是預防居家火災最直接且關鍵的衛教項目。
The highest priority instruction for oxygen safety is to avoid smoking near the equipment because oxygen supports combustion and significantly increases fire hazards. While storing tanks upright and away from sunlight is important for equipment integrity, preventing ignition sources is critical for client safety. Electrical appliances can generally be used safely if maintained properly and kept at a safe distance.
