Abstract: On the day of the accident, Employees #1 and two coworkers were preparing to replace and repair ceiling tiles at this office area. At approximately 12:00 p.m. on April 9, 2009, Employee #1 left to go to lunch, and the coworkers sprayed various chemicals which included compounds such as acetone, propane, n-butane, and xylene. When Employee #1 returned from lunch at approximately 12:30 p.m., she was overcome by the chemicals and experienced tightness in her chest and was coughing from the exposure. Employee #1 left the area for approximately 30 minutes, tried to return, and left again for another 30 minutes to 45 minutes. From approximately 1:30 p.m. to 1:45 p.m., Employee #1 stayed at work until her supervisor returned from a meeting at approximately 3:00 p.m. At this time, Employee #1 told the supervisor that she was "overcome by the fumes" and that she was going home. On April 10, 2009, Employee #1 was admitted to the hospital due to low oxygen in the blood stream. Employee #1 was diagnosed with "Chemical Bronchitis due to chemical exposure" and was released on April 12, 2009.
