On 5/29/10 five people were boating on El dorado Reservoir in the operator’s cabin vessel.  They had been tied up in the Rock Quarry most of the day with the generator running.  Three people spent most of their time inside the cabin of the boat with the AC running.  At some point during the day Occupant1 started to feel ill and lied down inside the vessel.  She continued to feel worse and started throwing up.  Her parent's thought she may have gotten overheated or may be coming down with the flu so they asked Operator to take them back to Shady Creek Marina so they could take Occupant1 home.  On the way back to the Marina Occupant1 continued to get worse and two other people also started to get dizzy and sick to their stomachs.  Once at shady Creek Marina Operator contacted NRO, whom was in the parking lot taking care of some other issues and asked if it would be okay to pull into the no parking to load Occupant1 into the vehicle because she was sick and could not stand up.  NRO told them that was fine and asked what type of symptoms she was having.  They explained that she was dizzy, throwing up and could not stand.  NRO knew that they had been in the Rock Quarry most of the day and asked about carbon dioxide poisoning.  Operator stated that he had alarms inside the cabin but they had not gone off so he did not think that was it.  NRO told them to stop at his location in the parking lot to have EMS look at her since they were already there for another medical call.  NRO advised El Dorado fire Dept. that there was truck pulling up with a very sick girl inside if they would check her for carbon dioxoide poisoning.  They advised they would.  Once Occupant1 was tested, it was discovered that she had a 34% carbon dioxide in her blood.  At this time NRO had them check her mother and she had 34% carbon dioxide in her blood.  NRO went down to the marina slips where Operators boat was parked and found operator’s wife lying down and not feeling good.  NRO took the third victim up to where occupant2 and occupant1 were at and had her tested also.  The third victim’s test results were lower but she still had a 28% carbon dioxide in her blood.  El Dorado Fire advised Butler Co Dispatch to dispatch 2 more ambulances to the Shady Creek Marina for 3 carbon dioxide poisoning patients.  Both occupant2 and occupant1 were transported to St. Francies Hospital in Wichita and occupant3 was transported to Susan B. Allen Hospital in El Dorado.  They were all 3 treated with 100% oxygen for several hours and then released.

NRO had Operator check both of his alarms in his vessel and both tested in working condition.  Operator stated that he was going to get new alarms and have them installed and was also going to have the generator exhaust system looked at and fixed if repairs were needed.
