Dear Ms. Johnson:
This is in response to your letter dated October 19, 1999
regarding the compatibility of hazardous materials packaged in
the same outer packaging under the Hazardous Materials
Specifically you ask if
materials described as "Paint, 3, UN1263, PG II" and "Corrosive
UN3264, PG III" may be packaged in the same outer packaging.
liquid, acidic, inorganic, n.o.s. (chromic/phosphoric acid), 8,
Hazardous materials may not be packed or mixed together in the
materials if such materials are capable of reacting dangerously
same outer packaging with other hazardous or non-hazardous
with each other and causing: combustion or dangerous evolution of
heat; evolution of flammable, poisonous, or asphyxiant gases; or
formation of unstable or corrosive materials ($ 173.24 (e) (4)).
Also see $ 173.21 (e). It is the shipper's responsibility to
determine weather any of these dangerous reactions can occur.
I hope this satisfies your request.
Sincerely,

The materials are Paint, 3, UN1263, PG II and Corrosive Liquid, Acidic,
Inorganic, NOS, (chromic/phosphoric acid), 8, UN 3264, PGII.
Arthur informed me that the DOT has no specific segregation requirements
and as long as the products don't cause a hazard when mixed that it is okay to ship
them in the same outer packaging. Could you please state the specific rule in
