I was walking near room 9 on the ground floor at 4:30 pm. I saw worker James Bond. He fell down on the floor because the floor was wet. There was oil on the floor. He slipped and landed on his right arm. He screemed. He was in pain. Three people ran to help him. After that, I called for an ambulance and paramedics arrived after 5 minutes. They examined James Bond and decided to take him to hospital to receive medical care. James will stay in the hospital for one week.
