To avoid the danger of explosion:

• Always use suitable insulating lids (pay attention to waste gas opening).

• Observe filling levels to avoid the formation of ice on the insulating lid.

• Set up the vessel in dry and roofed rooms.

• Monitor atmospheric humidity in the installation room.

• Check vessel regularly for the collection of condensed water.

• Check vessel regularly for damage to surface or material damage

Oxygen may be condensed from the air if liquid nitrogen is used and similarly be

liquefied because the boiling point of oxygen (approx. -183° C) is above that of

nitrogen (-196° C).

The following points must be considered in the case of oxygen enrichment:

• Do not smoke.

• Where possible, keep easily inflammable materials away from the vessel.
