[Discription of Incident]
The victim of this
accident suffered from acute pneumonia when he was engaged in work to add
hypochlorous acid soda, etc., to a tank for the drinking water facilities
at a hot springs site.
The victim who was
on the day shift continued working as he was also taking a night shift in
place of his colleague.
During a routine
patrol of drinking water facilities around 8:45 p.m., the victim found
that only about 10 percent of the volume of polychlorinated aluminum and
hypochlorous acid soda remained in the stirring tanks. Accordingly, the
victim first replenished the hypochlorous acid soda. When the victim
opened the tank cover to replenish polychlorinated aluminum, a strong
chlorine-smelling vapor was emitted and the victim inhaled the
gas.
Because of
inhaling, the victim started coughing violently, with the severely
irritating odor of the gas infusing his nasal passages and lungs. As the
victim continued to have symptoms that included burning in his throat and
chest, he underwent an examination at a hospital where he was diagnosed
with acute pneumonia and liver function impairment due to chemical
damage.
