What problems are encountered during the use of liquid dewar cylinder?

Liquid dewar cylinders are commonly used for the storage and transportation of cryogenic liquids such as liquid nitrogen, oxygen, and argon. While they are generally safe and reliable, there are several problems that can arise during their use. Here are some of the most common problems encountered:
Overfilling: Overfilling the dewar cylinder can lead to pressure build-up and potentially cause the cylinder to rupture. It is important to follow the manufacturer's instructions regarding the maximum filling capacity.
Pressure build-up: Cryogenic liquids can evaporate and cause pressure build-up inside the dewar cylinder. This can lead to safety hazards and potentially damage the cylinder. It is important to periodically vent the cylinder to release excess pressure.
Frost formation: When the dewar cylinder is in use, it can develop frost on the exterior surface. This can make it difficult to read the level of the liquid inside and can also be a safety hazard if the frost becomes too thick.

Leakage: Dewar cylinders can develop leaks over time, either due to wear and tear or manufacturing defects. Leaks can be hazardous as they can cause the cryogenic liquid to rapidly evaporate and potentially cause injury.
Transport hazards: When transporting dewar cylinders, there is a risk of tipping or dropping the cylinder. This can cause the liquid inside to slosh around, potentially causing pressure build-up and increasing the risk of injury.
To avoid these problems, it is important to follow the manufacturer's instructions regarding the use and maintenance of dewar cylinders, and to handle them with care. It is also important to have proper training and protective equipment when working with cryogenic liquids.
