We haul hazmat everyday with a cargo van, TT, and ST. MSDS goes with every load unless it's required to have an emergency response sheet instead. C/Van or any other mode of transportation all require the same paperwork.
I should ad that MSDS and or Response sheet is furnished by the shipper. Placards are optional but you should be told before you arrive to load so you can purchase them before you arrive.
C/Vans require bulkhead.
