consequence is similar to burn.
3) When cryogenic liquid splash into the surface of skin, it will freeze a big area quickly.

heat insulation, otherwise when you try to walk away, the cryogenic metal will fast
stick and tear up your skin. The primary emergency measure for this accident is to

5. VENTILATION DEVICE
Cryogenic Pump only be installed and operated in a well-ventilated environment. In order to
prevent gas excessive accumulation, handle with cryogenic liquid where must be always in a
well-ventilated area. When there is no lifeline or no companion traction on the other side,
never allow enter container or building which may have cryogenic gas. Because exist a
serious security hidden danger when companion entry into a closed environment to save the
fainted workmate.
NOTE
！
The mist steam generated when cryogenic liquid contact with air is just steam rather
than gas itself. The gas that liquid vapor is invisible.
6. NITROGEN SYSTEM
Nitrogen which was vented or discharged to a closed area can replace 21% oxygen in the air.
If people try to come into the atmospheric environment of low oxygen content, that will result
in suffocation without any obvious sign. When oxygen concentration is less than 15% or lower,
it will cause drowsiness and confusion, and that symptoms may be concealed by mental
pleasant illusion. When oxygen concentration is less than 12% or lower, people will lose
consciousness immediately without any obvious sign. If someone stay in low oxygen
environment for a long time, that will lead to brain damage even death. Transfer the people to
well ventilate area immediately, who seem to have any symptom of dizziness or lose
consciousness during doing relevant work of nitrogen. Artificial breath should be taken
immediately, if breath has stopped. Also should request medical assistance at once,
