Is Nitric Oxide flammable?

Nitric oxide is classified as a non-flammable gas. It does not support combustion and does not ignite in the presence of a flame or spark. Understanding this characteristic is essential, especially in medical settings where nitric oxide is utilized for its vasodilating properties to treat conditions like pulmonary hypertension.

While nitric oxide can react with other substances, particularly in the presence of oxygen, these reactions do not imply that nitric oxide itself is flammable. In fact, nitric oxide's role in medical applications is often focused on its ability to improve blood flow without presenting a fire hazard.

In contrast, other options imply conditions under which nitric oxide could potentially be flammable, which is not accurate for its fundamental properties. This clarity on nitric oxide's safety profile is crucial in ensuring proper handling and awareness in medical gas administration.
