Here is a copy paste of the new standard.
"An air operator shall provide Crew Resource Management Training (CRM) to flight crew, flight attendants, dispatchers/flight followers, ground crew and maintenance personnel, as applicable, in accordance with paragraphs (a) and (b) of this subsection."
Notice it never mentions "crew member", it only mentions "flight crew". Very big difference(See CARS Part I Subpart 1). AC 700-042 also mentions that the intent is for persons employed by the operator, so that rules out fire fighters falling under the "ground crew" requirement as well.
