1. Once a large amount of aerosol occurs at the operation site, or the liquid nitrogen fluid splashes and flows, immediately evacuate the site, and a valve closes the leak source when the leaked area is accidentally closed. Pay attention to safety protection.
2. Involving liquid nitrogen operation, it is necessary to wear a safety mask to protect the face and eyes, and to prevent cold and penetration into the glove protection hand. The tooling must be fully worn without proper exposed parts.
3. Switching operation The liquid nitrogen valve must be in a relatively open position where the upwind direction may be at the point of leakage or leakage.
4. Before using liquid nitrogen, in use, after the end of use, keep in contact with the downstream use of liquid nitrogen in the whole process, in case of accidents and timely treatment.
