Based on a comprehensive review of the evidence, including Claimant's testimony, the expert medical opinion, the medical treatment records and bills, and the other documentary evidence in this matter, as well as based on my personal observations of Claimant at hearing, I find:
1) Claimant is a 39-year-old man, who was employed by Domino's Pizza/MBR Management Corporation (Employer) as a general manager at their store in Troy, Missouri at or about the time of his accident on July 8, 2012. He had worked for Employer for 2 to $21 / 2$ years prior, answering phones, making pizzas and delivering them. As the general manager, he was responsible for scheduling, making/cutting pizzas, doing paperwork and supervising the route drivers. He generally worked five days a week from 9:30 a.m. to 7:00 or 8:00 p.m., and, then, Sunday from 4:00 p.m. until 1:00 or 2:00 a.m. Based on his prior experience working in the pizza making/delivering industry, he said that he wanted to make sure the store he worked at had an air conditioner that worked, because some stores had none and the temperatures would top 100 degrees in the summer between the heat outside and the heat coming from the pizza ovens. He testified that the store in Troy, Missouri, where he worked, had an air conditioner, but it was not working very well.
2) Claimant explained that the heat was greatest by the pizza ovens and the temperature by the ovens was always higher than what showed on the thermostat that was hanging by the office. He testified that there was a conveyor oven (top and bottom) for baking two pizzas at a time, which were set to 490 degrees. During the summer of 2012, at or around the time of his injury, Claimant testified that the temperature outside was in the mid-100 degrees, and inside, 95 degrees was the lowest he saw on the thermostat.
3) Claimant noted that he had asked his boss many times to fix the air conditioning in the store before July 8,2012 , but he was told that it was not a high priority for his boss because there were other stores that did not have any air conditioning at all. He said that he often worked with cold rags on his neck or he would step into the cooler to try to cool off from the excessive heat in the store.
4) Claimant testified that 2012 was a really hot summer. By July 8, 2012, he had been working all week in the excessive heat in the store and progressively felt worse as the week continued. He said he felt dizzy, nauseous, weak and lightheaded. He called his supervisor to report his complaints and the supervisor told him to go to the hospital, so he went to St. Joseph Hospital West.
5) Medical treatment records from St. Joseph Hospital West (Exhibit 2) document Claimant's admission to that facility on July 8, 2012 for complaints of general malaise, dizziness, nausea, being very tired and having worked in 97-degree temperatures for four days. He was diagnosed and treated for heat exhaustion, as well as acute renal failure and dehydration. He was also found to have iron deficiency anemia, so he received a battery of tests, including a colonoscopy and upper endoscopy. He was discharged from the hospital on July 11, 2012. Among the
secondary diagnoses listed on the summary sheet from the hospital are, "Accident caused by excessive heat due to weather conditions" and "Injury or poisoning occurring at/in public building." These secondary diagnoses suggest to me that the doctors treating Claimant at the hospital related the need for his admission and treatment to the heat exhaustion and heat exposure he had been exposed to at work for the days leading up to July 8, 2012.
6) Claimant testified that after his hospital admission, he took the rest of the week off and returned to work for Employer the following Monday. He admitted that his kidney function had returned to normal when he was released from the hospital the first time. He said that on Monday and Tuesday when he worked, he noticed that the heat was decreased in the store and the air conditioning was working better, but it was still hot, with the thermostat in the 80s. He took off Wednesday because he started progressively feeling bad again (nauseous and lightheaded), and, then, he went back to the hospital, as he was told to do at discharge, if he started feeling bad again.
7) Medical treatment records from St. Joseph Hospital West (Exhibit 2) document his second admission on July 19, 2012 for a diagnosis of acute renal failure, which the doctor characte
