This SCCM was according to report in physical contact with the FD but they didn't respond to her because they were busy.
Well, then surely they are working on the problem, and her job is to STAND BY and wait for further instructions, OR in the important cases make sure she get response, eg. slap a shoulder or whatever is required.
But no, she took her own actions and for doing that in those circumstances, she is in the wrong job.
Very dangerous for all pax, regardless of what all the uninformed and non-trained self-loading freight in here thinks
