At 6:56 on August 27th, local time in Japan, a hydrochloric acid leak occurred at the Kashima plant of Asahi Glass Co., Ltd., the world’s second-largest glass manufacturer, located in Ibaraki Prefecture, Japan. According to information released by the company, holes were found in the hydrochloric acid storage tank, and it is estimated that around 1,200 tons of hydrochloric acid leaked out. Around 8 o’clock after the accident, the local fire department urged residents in the area to close their doors and windows and to limit going outside as much as possible. Currently, 4 employees of the company have been taken to the hospital by ambulance due to symptoms such as sore throats.
Asahi Glass, with perforations at the bottom; it is said that the substance has been discharged into the sea. Why wasn’t caustic soda used to neutralize it before discharge? Is 1200 tons the total amount of liquid, or the total amount of hydrochloric acid after conversion to a percentage basis? Hydrochloric acid is usually available in two concentrations: 31% and 18%. Looking forward to detailed reports later!
Once a leak is detected, shouldn’t the acid be poured into an empty storage tank right away? How can one allow it to continue leaking?
Due to poor routine inspections and equipment management, Japan is also a society prone to fraud.
Can such a thing still happen? Does that hydrochloric acid storage tank not have a level monitoring system? 1,200 tons of hydrochloric acid – that’s almost 1,000 cubic meters in volume. Such a large amount leaked, and it was only discovered so late; did they detect it using their noses?
What material are hydrochloric acid storage tanks usually made of?
There aren’t many subsequent estimates, and the report itself is vague – could it be that the seawater itself neutralizes it?
For a tank of this size, could it be a carbon steel shell with an internal lining, and the damage to that lining has caused corrosion of the shell?
