We entered into the field of carbon monoxide legal representation as experts we worked with in brain injury cases alerted us to the brain damage that was so common after carbon monoxide poisoning.

Unfortunately, many of the most important questions after CO poisoning are not the most commonly asked questions about carbon monoxide poisoning. So in addition to the commonly asked questions, we will also answer some of the important questions that even ER doctors and neurologists get wrong.

The CPSC’s general page CO page is a good resource, but an even more thorough treatment is the information they published about the CO risk from Portable Electric Generators. For those resources, click here. Unfortunately, more than a decade of rule making from the CPSC on the lowering of emissions from portable electric generators was shelved in the last couple of years.
