The hydrogen tank explosion, which killed eight people in Gangneung last spring, is said to be caused by the inflow of oxygen into the tank. However, before the accident, the oxygen concentration inside the hydrogen tank had already exceeded the standard value, and the safety recommendation was made, but it was revealed that it was ignored.

The hydrogen tank explosion, which killed eight people in Gangneung last spring, is said to be caused by the inflow of oxygen into the tank. However, before the accident, the oxygen concentration inside the hydrogen tank had already exceeded the standard value, and the safety recommendation was made, but it was revealed that it was ignored.

In less than a month after commissioning, it was confirmed that the oxygen concentration in the hydrogen tank once exceeded the standard.

Normally, if the oxygen concentration exceeds 2% in the hydrogen tank, the risk of explosion increases and the operation should be temporarily stopped. At that time, the concentration of oxygen was detected at 3%.

[Explosion victim: I heard that there was an abnormal oxygen inflow. I heard that the figure was about 3%.]

In particular, the Korea Gas Safety Corporation recommended the installation of filters to reduce the oxygen concentration at that time, but it was reported that no action was taken until the accident occurred.

It has also been revealed that this project, which had been conducted as a government research and development project,

[Kim Dae-geon / Chairman of the Korea Accident Prevention Corporation: It seems that hydrogen production did not start until five days before the end of the project. It is estimated that the project itself was very hasty and poorly progressed because it failed to meet the target time of 1,000 hours.]

Kangwon Techno Park, which provided the site, confirmed that even the companies in the industrial complex were not informed about the installation of the hydrogen tank.
