Neon, Ne Specialty Gas

Neon is a chemical element with the symbol Ne and atomic number 10. It is a noble gas. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. Neon is used for vacuum tubes, high-voltage indicators, lightning arresters, wave meter tubes, television tubes, and helium-neon lasers. Liquefied neon is commercially used as a cryogenic refrigerant in applications not requiring the lower temperature range attainable with more extreme liquid helium refrigeration.

Neon Safety Requirements:

Safety Requirements: The cryogenic liquid will rapidly boil to the gas at standard temperatures and pressures. The liquefied gas can cause frostbite to any contaminated tissue. The main health hazard associated with the release of this gas is asphyxiation by displacement of oxygen (see SDS for further information).
