Liquid Nitrogen Safety Operation Method

Liquid nitrogen is inert, colorless, odorless, noncorrosive, extremely cold (-320° Fahrenheit), and nonflammable.

Personal Protective Equipment:

Chemical splash goggles, face shield, and gloves of impermeable material should be used.Long sleeves and cuff-less trousers/slacks are also recommended during handling, transfer operations or whenever the possibility of exposure to liquid nitrogen spills exists.

Safe Handling:

Impact resistant containers that can withstand the extremely low temperatures should be used.Materials such as carbon steel, plastic and rubber become brittle at these temperatures.Use only approved,unsealed containers.Never pour liquid nitrogen into a thermos.Never seal liquid nitrogen in a container.Vaporization could cause the container to build up enormous pressure and explode.
