The attention to detail in “Chicago Fire” is exquisite. On top of the extensive training that the cast goes through, per Showbiz Cheat Sheet, the firefighting series regularly features actual equipment used by real firefighters to make it as believable as possible. In April 2018, fire safety brand 3M Scott Fire & Safety tweeted a shoutout to actor Joe Minoso’s character Joe Cruz for wearing the Air-Pak X3 Pro SCBA (Self Contained Breathing Apparatus), which are used to supply firefighters with breathable air.
However, there are times where the gear used in the show makes the series seem unrealistic, namely the same Scott Air-Pak used by the firefighters in the show. Veteran firefighters took to the Firehouse forum to share their skepticism over the SCBA. One user questioned if the face piece was purely cosmetic, writing, “So what is wth the funky face pieces on the Scott masks? Is this a new mask I haven’t seen yet or something custom made for the show so you can see the actor’s face?” Another user surmised that the masks seemed standard, but may have been missing the nose cup.
