After 9/11 they put Hydrogen Peroxide on some sort of list and I was no longer able to buy it for my Jacuzzi. It is a great, healthy alternative to Bromine and Chlorine but it’s not on the list of sanitizers for hot tubs, pools, etc. I know it’s highly combustible because I read where someone spilled it on a wooden deck and someone threw a cigarette down and it was instantly a huge fire and nearly burned the adjacent concrete house down.
Hydroden peroxide is classified as an oxidizer.
