The husband of a woman who died while scuba diving is suing the international diver training organization PADI, alleging it inadequately teaches
divers to protect themselves from carbon monoxide poisoning. Tests revealed her scuba tank contained lethal levels of carbon monoxide. Husband Colin Crosss lawyer said PADI has roughly a page and a half that deals with the quality of air in the tank that you’re using to dive. It examines bad air, it examines what to do. It’s PADI’s recommendation to test your tank by tasting it. But the problem is that carbon monoxide is tasteless and odourless.
