LN2 for overclocking: with others

•  Storage of the LN2 •  Safe and venHlated area

•  If possible outdoors (if large quanHHes) •  Keep area clean, Hdy and accessible at all Hmes! •  Protect access to the Tanks •  Tanks are heavy! Make sure to distribute the weight



•  Workspace recommendaHons •  Keep your bench desk clean and organized •  Clean drink and trash as you go through the session •  Mount all you containers properly •  Make sure the table is stable •  Keep it to your space, to not invade others



•  Safety •  Wear the required PPE •  Follow the refilling procedure •  Be aware of the local emergency number and locaHon procedures. •  Don’t make “the show” by spiing LN2 •  Don’t pour LN2 on the floor •  Alcohol: Moderate yourself! No drunk benching.


Use and maintain cryogenic tanks

About cryogenic tanks

•  Typical pressure: 350 PSI (if pressurrizes) •  Capacity 80 to 600L •  Build with several safety measures to avoid pressure build-‐

up •  Always report a damaged tank •  Do not operate if you are not sure of how it works
