transported as "petroleum products" can only transport one of these materials (*a.* butadiene *b.*
kerosene *c.* nitrogen *d.* anhydrous ammonia) - b. kerosene
Some products are allowed to ___________________ as they travel one after another through the same
liquid pipeline - co-mingle
Example of a material found in a type B radiation container - high level spent fuel from a nuclear power
plant
