Members of City Council are questioning whether a controversial new policy that treats some city fire runs as lower priority is warranted amid concerns over its rocky implementation. Detroit Fire Commissioner Eric Jones led a presentation Monday on the policy he put in place in August that has emergency dispatchers coding runs as emergent and non-emergent, a classification that now deploys crews to some scenes without lights and sirens. Jones instituted the protocol to protect residents and firefighters, saying disregarding traffic signals and speed limits with the activation of lights and sirens for every single run — even when it's not urgent — is dangerous. But the city's fire union has criticized the move as a "public safety nightmare," saying that runs are repeatedly being dispatched improperly.
