Has the use of ventless products led to any CO (carbon monoxide) deaths?
In the United States, the Consumer Product Safety Commission (CPSC), which is charged with protecting the public from unreasonable risks of serious injury or death related to home appliances, has stated that it is not aware of any documented incident in the CPSC In-Depth Investigation (IDI) database of fatal carbon monoxide (CO) poisoning associated with an ODS-equipped ventless gas heating product. In the United Kingdom, approximately 15 million ODS-equipped ventless units have been installed with no reported CO deaths. Japan reports that more than 40 million units have the same outstanding safety record.
