A cryogenic liquid is defined as a liquid with a normal boiling point below –130°F (–90°C). The most commonly used industrial gases that are transported, handled, and stored in the liquid state at cryogenic temperatures are argon, helium, hydrogen, nitrogen, and oxygen. Cryogenic protection is needed to handle them. <strong>PPE for cryogenic protection</strong> The recommended personal protective equipment for handling cryogens includes: a full faceshield over safety glasses, loose fitting thermal insulated or leather gloves, long-sleeved shirts, and trousers without cuffs. In addition, safety shoes are recommended for people involved in the handling of containers.
