On the morning of April 12, director of security at the chace use before the class time, in company training center of urea plant maintenance and management staff of nitrogen and cautions for use are training, and lists the accident case analysis.
He pointed out in the training, nitrogen content in the air is 78%, which will give you a certain misunderstanding, that the higher nitrogen content in the air, the use of nitrogen will not cause harm to people. In fact, the nitrogen, although non-toxic, but will cause suffocation. In particular, the high concentration of nitrogen inhalation of more than 90%, will quickly coma, due to breathing and heartbeat stop and death. So, only we understand the nature of nitrogen, know how to protect measures, in order to use it well in the actual production.
Through training, we believe that benefit from the elimination of the original misunderstanding, nitrogen has a new understanding.
