Backflow prevention should be provided for oxygen cylinders.

True
False

Correct Answer

A. True

Explanation

Backflow prevention should be provided for oxygen cylinders because it is essential to prevent the backflow of contaminants or other gases into the oxygen supply. Backflow can occur when there is a pressure difference between the oxygen cylinder and the surrounding environment, causing the flow of gases in the opposite direction. This can lead to the contamination of the oxygen supply, which can be extremely dangerous for patients who rely on oxygen therapy. Therefore, it is necessary to have backflow prevention mechanisms in place to ensure the purity and safety of the oxygen being delivered.
