5. Cryogenic liquids, when returned to the gaseous state, can displace oxygen from the air
under the right conditions. It is strongly recommended to use and store cryogenic liquids in
well ventilated areas only. It may also be prudent to install oxygen monitors in areas where
liquid nitrogen is stored and ventilation is minimal.
6. The CO2 cooling option is supplied with a cryogenic valve that can hold maximum pressure
of 1000 psi. In order not to exceed this pressure limit, the CO2 cylinder must be kept at the
temperature not higher than 25 °C.
7. Dewar with liquid Nitrogen should be handled and stored in an upright position. Do not drop
