The allegations include stripping and simulated sex at the August show. An investigation by Memphis police into officers' involvement is ongoing.
The investigations began after The Commercial Appeal newspaper published a column by Wendi C. Thomas about the show.
Thomas wrote that she saw nearly nude men with strategically placed soapsuds on stage and at least two women were ``hoisted in the air, their legs around men's waists.''
At least one person swung a badge, others wore department pants and held nightsticks. A show organizer said all the models were from the police and fire departments.
Michael Jubirt, deputy chief of the Memphis Fire Department, expects the hearings to be completed in two weeks and says there may be punishments.
Memphis Fire Director Richard Arwood said it's been difficult to get evidence of the firefighters' behavior because the department hasn't been able to get a videotape of the show.
