Interesting how you can use chemical hazard info to show something is 
benign or hazardous. Water actually kills more by far than all the other 
listed chemicals combined. I believe it is the third highest cause of 
death of children (drowning). One of my good friends died from it.

It is all in how you use it. OA is about 4% for the drip method and is 
fairly safe, but I would agree with it being a hazard when used in 
vaporizers. I would guess that cumophose is well down the hazard ladder, 
but I would feel more comfortable handling concentrated Sulfuric Acid 
than it.
