Which of the following is NOT a safe handling practice for oxygen tanks?

Dragging oxygen tanks is not a safe handling practice because it can cause damage to the tanks, increasing the risk of leaks or ruptures. Oxygen tanks are high-pressure vessels that should always be handled with care to maintain their integrity and ensure the safety of the environment around them. Transporting them properly typically involves using a hand truck or similar device to safely move the tanks without causing them to tip over or sustain physical damage.

In contrast, chaining tanks in an upright position is important as it prevents them from tipping and potentially causing accidents or injuries. Using proper protective equipment, such as safety goggles and gloves, is crucial to protect the handler during the operation. Keeping oxygen tanks away from combustible materials is essential because oxygen supports combustion, and any nearby flammable substance increases the risk of fire or explosion. All of these practices contribute to a safer environment when working with oxygen tanks, underscoring the importance of proper handling techniques.
