The review of safety

The other day, Expo Land in Osaka had a big accident. The bolt of corkscrew came off because of metal fatigue. As a result, a woman died and other passengers were injured. Not only in this theme park. but also in other facilities occurred the similar accidents. This may be came from lacking of a consciousness of safety. The safety check wasn't excuted and the reaction when the accident happened was not good. This brought about one death. This work treats people's lives, so is had to do with a great care and a definite safety. I hope that these facilities work without fogetting this disaster and never raise the same one again.
