As liquid nitrogen is a cryogenic substance – in other words, it exists at very low temperatures – handling it incorrectly can cause cold burns and frostbite. Care should always be taken when working with liquid nitrogen. It should be handled carefully while wearing personal protective equipment (PPE).

As it is odourless and colourless, liquid nitrogen is difficult to detect in the air. Therefore, it should only be stored in well-ventilated areas and transported in approved containers. Anyone handling liquid nitrogen should understand the relevant safe work practices that should be applied when working with it.
