Oxygen supports combustion, so safety is critical. Essential guidelines: Never smoke or allow smoking near oxygen equipment—this is the number one safety rule. Keep oxygen at least 10 feet from open flames, gas stoves, and space heaters. Don't use petroleum-based products (Vaseline, oil-based lotions) near oxygen as they can ignite. Store oxygen cylinders upright and secured. Ensure good ventilation in your home. Have working smoke detectors. Post "Oxygen in Use" signs. Never adjust oxygen flow without your doctor's approval. Keep a backup power source for concentrators during outages.
Follow oxygen safety rules: no smoking, keep away from flames, avoid petroleum products, and secure cylinders properly.
