Cryogenic liquid oxygen storage tank
The normal content of oxygen in the air is about 21%. Whether it is due to combustion or the entry of other gases, the reduction of the oxygen content in the air is potentially hazardous.
The normal content of oxygen in the air is about 21%. Whether it is due to combustion or the entry of other gases, the reduction of the oxygen content in the air is potentially hazardous. The operator must take necessary protective measures. If the oxygen content in the air drops to 15-16%, the burning of ordinary combustible substances (including those generally used as fuel for heating or lighting) will be extinguished. The oxygen content is slightly lower than this concentration, and individuals cannot make a clear judgment on the condition of the air they breathe, because symptoms such as drowsiness, tiredness, listlessness, loss of cooperation, misjudgment, and confusion may be caused by a kind of “abnormal excitement” The state of “” is covered up, making the victim mistakenly believed to be in a safe and good state.
