Potential health effects

Effects of a Single (Acute) Overexposure Inhalation. Breathing 80% or more oxygen at atmospheric pressure for more than a few hours may cause nasal stuffiness, cough, sore throat, chest pain, and breathing difficulty. Breathing oxygen at higher pressure increases the likelihood of adverse effects within a shorter time period. Breathing pure oxygen under pressure may cause lung damage and also Central Nervous System (CNS) effects resulting in dizziness, poor coordination, tingling sensation, visual and hearing disturbances, muscular twitching, unconsciousness, and convulsions. Breathing oxygen under pressure may cause prolongation of adaptation to darkness and reduced peripheral vision. Skin Contact. No harm expected. Swallowing. This product is a gas at normal temperature and pressure. Eye Contact. No harm expected. Effects of Repeated (Chronic) Overexposure. No harm expected.
