Comments

A powerful oxidizer and explosion hazard; Liquid may cause frostbite; Inhalation of 100% oxygen for 24 hours can cause pulmonary edema; Chronic exposure to high concentrations of oxygen can cause lung scarring; [CHEMINFO] Oxygen toxicity is observed in mechanically ventilated patients treated for hypoxic respiratory failure. Exposures to oxygen at FIO2 of 50 to 60% for more than 6 hours can cause lung injury including alveolar edema, formation of hyaline membranes, hypoxemia, and progressive fibrosis. [Cecil, p. 578-9]
