Which of the following describes a nonflammable gas?

A nonflammable gas is defined as one that does not ignite easily and does not support combustion. The choice that states a gas that does not meet the definition of a flammable gas accurately captures this characteristic. Nonflammable gases, such as nitrogen, helium, and carbon dioxide, are commonly used in various applications, including medical settings, because they can be safely handled without the risk of ignition.

Understanding this definition is crucial when working with gases in any environment, particularly in medical facilities where the use of nonflammable gases is essential for patient safety and compliance with regulatory standards. Recognizing that a nonflammable gas is safe from igniting or supporting flames is vital in preventing hazardous situations.
