What is a key component of safe handling of oxygen?

A key component of safe handling of oxygen is ensuring that the oxygen tank is secured to prevent tipping. Oxygen tanks are under high pressure, and if they tip over, there is a risk of them becoming damaged or causing injury. A falling tank can become a projectile, posing danger to individuals nearby and potentially leading to damage to the tank or infrastructure. By securing the tank properly, it minimizes the risk of accidents and ensures a safer environment for both the patient and caregivers.

Each of the other choices involves practices that could pose hazards. For example, lubricating connections with oil is dangerous because oil can create a fire hazard in the presence of oxygen. Chilling the tank and tubing could lead to frostbite on the tubing and may inhibit the oxygen's function. Allowing the resident to adjust the flow rate without supervision can lead to improper oxygen delivery, which can be harmful to their health. Therefore, securing the tank is the most crucial aspect of safely handling oxygen.
