Liquid nitrogen is used for a variety of applications, including cryogenics, in medicine, and as coolant. However, if it is not handled properly, this chemical can be extremely dangerous. With a boiling point of -320ºF, if it comes into contact with the skin, it quickly causes cryogenic burns and frostbite. On top of this, liquid nitrogen is odorless and colorless and may result in an oxygen deficient atmosphere in a confined space.
If your facility involves the use of this dangerous chemical, you need to implement liquid nitrogen warning signs, which alert workers to be careful. These signs warn against touching the liquid and remind employees to don the proper PPE prior to handling. Liquid nitrogen warning signs enhance the safety in your facility.
