Workers who operate cryogenic liquid storage tanks should have a detailed understanding of the structural characteristics of the equipment and its pipe and valve systems.

LNG is usually stored in cryogenic storage tanks at -162°C and a pressure of about 0.1MPa.

Use of cryogenic liquid storage tanks

Content

1.1 Workers who operate cryogenic liquid storage tanks should have a detailed understanding of the structural characteristics of the equipment and its pipe and valve system, be familiar with the dangerous characteristics of cryogenic liquids, strictly control the surrounding environmental conditions, and operate in accordance with the safe operating procedures of cryogenic liquid storage tanks. Operators must pass the training and assessment of the technical supervision department and hold a pressure vessel operation qualification certificate before they can start working. Before operating, workers should take labor safety protection measures in accordance with regulations.
