All recommendations are suggesting the use of "upstream" traffic cones in addition to using apparatus in a blocking position as indicated in the photo below:

My question is this:
Why would we voluntarily place people (most likely a single person) on the "wrong" side of the apparatus to go place traffic cones? We position the apparatus to protect our people....right?
If people can't see a fire engine or truck parked sideways in the street, are little orange traffic cones really gonna help?
It seems like very little reward for the risk.
