We report the circumstances known at this time, concerning the fire at our peracetic acid plant of the Ohtake Plant on July 18, 2017.

We apologize again for the major inconvenience caused by this accident.

1. 1Recovery Conditions
   We proceeded with repair work of reboiler in B line by using backup items in September. In addition, we finished the high pressure gas completion inspection on November 1 and the fire completion inspection on November 2.
2. 2Plans for recommenced manufacturing
   We will start manufacturing peracetic acid from the end of November 2017, while ensuring production safety. However, under initial plans, operations will only be at up to 50% of the maximum load capability.

From December 2017, we will successively restart the production of other derivatives.
