Having spent many years on a hazmat team myself this incident makes me glad that I am now retired. However this article is a little over the top. The place was a chemical factory... of course there are going to be dangerous chemicals stored there and many of the products of combustion are harmful as well. And we are talking about the Chinese government... they have killed untold millions of their own citizens on purpose, they will lie about whatever they want whenever they feel like it. It is not really necessary to drab the Japanese into the story to convince us.
it’s more than just a little - but there are some facts (such as the number of repeat fires) on ongoing issues I hadn’t seen yet.
