Precautions for using cryogenic protective coverall

Cryogenic protective coverall mainly provides full-body low-temperature protection for personnel working in liquid ammonia operations. It belongs to the category of low-temperature protective clothing. It is mostly used in liquid nitrogen, liquid ammonia, natural gas, laboratories, aerospace research institutes, low-temperature environments, and frozen storage rooms. , freezers, laboratories and low-temperature workplaces. Liquid nitrogen protective clothing generally consists of three layers of protective materials, two of which are thin layers made of insulating materials. The inner layer of material has high thermal insulation, allowing it to take away moisture through capillary action. The following are the precautions for cryogenic protective coverall compiled by the editor of C&G.

1. Read the instructions for use: Before using the liquid nitrogen protective clothing, read and understand the instructions for use in detail. Make sure you understand how to put on and take off protective clothing correctly and how to respond to unexpected situations.
