The Ministry of Labour is investigating after two men became sick at a workplace in Chatham.
Chatham-Kent Police, Fire, and EMS were called to the business on Richmond St. yesterday after one of the men vomited then fell to the floor and became unresponsive.
Police say the men were working near a propane powered forklift.
The workplace was evacuated and an air test found levels of hydrogen cyanide and carbon monoxide. Businesses in the area were also evacuated.
The two men were taken to hospital and treated for poisoning.
