I work 48/96 in a 1 station department that runs approximately 2000 runs a year. Not crazy busy by any definition. It can be rough if we get a couple of after midnight calls the first night but can usually rotate off the rescue so we don't get it 2 nights in a row unless of course multiple calls come in while the first out is on a call. Everyone here loves it because everytime we go home its a 4 day weekend! Overall its not more hours if you already work 24's. You just work your shifts all at once instead of 24 on /24 off followed by a 4 or 6 day once a month or so depending on the exaxt schedule which is the norm on the west coast . It can be a little long to be away from home, but then being home 4 straight days seems to keep everyone in the family sane.
