* '''Be aware of asphyxiation''' - One of the greatest dangers of LN2 is asphyxiation. LN2 can displace upto 600 times its own volume when it boils. This can lead it to displace all the oxygen in the room, which can lead to a situation where you are asphyxiating in a near pure nitrogen atmosphere without realising it as you can still exhale CO2. Always use LN2 in small quantities, in a large open, ventilated room. See http://en.wikipedia.org/wiki/Inert_gas_asphyxiation for more information. | |||
* '''Wear appropriate clothing''' - This should be clothing that has long sleeves, tight cuffs and the special cryogenic gloves provided. Do not wear any other kind of gloves or any clothing that has significant folds, creases or places where any splashed liquid could pool. Wear footwear that covers the entire foot, i.e no sandals! | * '''Wear appropriate clothing''' - This should be clothing that has long sleeves, tight cuffs and the special cryogenic gloves provided.
