MUSKEGON COUNTY, MI – Twenty-six people were being received at two local hospitals as of 6 p.m. Friday, July 11 in response to a Hazmat emergency at Michigan's Adventure, said Joan Kessler, spokeswoman at Mercy Health Muskegon.

Muskegon County Sheriff Dean Roesler has confirmed that a combination of chemicals were released in the area of the park's wave pool which combined to make chlorine gas.

The park is looking into the incident, Roesler said. At least 50 people were evaluated, some of which were individually hosed down in the Michigan's Adventure parking lot.

Emergency personnel treat victims who were involved when chemicals were released in an area at the water park at Michigan's Adventure on July 11, 2014.

One witness in the park said she "got a splash of chlorine" and started coughing while finding it difficult to breathe. Other witnesses reported burning lips.

Multiple ambulance and fire officials responded to the scene as well as a Hazardous Material Response Team (Hazmat) just after 4 p.m.

Staff reporters Tony Wittkowski and Brandon Champion contributed to this report.
