There are hazards associated with neon, including suffocation with inhalation, corneal frostbite with eye contact and frostbite with skin contact. Overall, this type of gas has low reactivity making it very stable, but the hazards are present in both gas and liquid form.
Morris Travers and William Ramsay discovered neon in 1898. In a vacuum discharge tube, the gas has a reddish-orange color. It is one of the most noble of the noble gases and is cheaper compared to helium in most cases. It is a common component in neon signs. Other common uses include lightning arrestors, television tubes, high-voltage indicators and wave meter tubes.
