Narrative:

I was the captain on aircraft X. Upon arrival at the aircraft our planned dg [dangerous goods] manifest showed 54 pounds of explosives in 7 packages. I queried dispatch who patched in the dg personnel. I asked them exactly what were we carrying. They could only tell me that the items were the least dangerous explosives (an oxymoron if I've ever heard one); that the amount was right at the limit of what could be carried and that the explosives were the only type of explosives [company] would carry. Yet with all that information; they still could not tell me what exactly we were carrying. In the interest of safety; I had the cargo removed. We departed on time.
