Actually, that fertilizer is not an Orica product. It is a knock-off with a slightly misspelled but similar name. That said, if it was the result would have been the same. The problem was not the product. If you follow safe handling and storage guidelines ammonium nitrate should be safe. Obviously storing it with fireworks and welding next to that combo is probably not in the Orica safety data sheet.
