Final answer:
Level 1 support gases used in healthcare, such as medical oxygen, have additional hazards including asphyxiation, higher storage pressures, and a greater potential for explosion compared to other medical gases.
Step-by-step explanation:
Level 1 support gases such as medical oxygen used in healthcare facilities carry additional hazards compared to other piped medical gases. These hazards include the risk of asphyxiation, which can occur if the oxygen levels are too high and displace the atmospheric air needed for normal respiration. Additionally, these gases are stored under higher pressures in cylinders, which requires stringent safety measures to prevent accidents. Furthermore, certain gases can be more highly explosive when mixed with air or other substances. Therefore, safety precautions are imperative when handling and administering medical gases.
