What is Nitric Oxide?

Nitric Oxide is a colorless gas, with a sharp, sweet odor. Nitric Oxide is an unstable, free-radical gas that reacts rapidly with oxygen to form nitrogen oxides. Nitric Oxide is produced in many mammalian tissues and is a mediator of cell-to-cell communication. It functions in many biological processes, most notably vasodilation, inflammation, and neurotransmission. It is noncombustible but as an oxidizer, it accelerates the burning of combustible materials. Heating nitric oxide under pressure will cause it to explode and rocket. Nitric Oxide is very toxic by inhalation and skin absorption.

Nitric Oxide Exposure and Health Risks

Nitric Oxide is very toxic by inhalation and can be fatal even after a very short exposure to small quantities. It is an irritant to the eyes and respiratory tract. Irritation can cause burning and coughing. Labored breathing, organ damage, and unconsciousness may occur hours after exposure. Low concentrations can be dangerous even for a short time. High concentrations can be fatal after a very short time.
