it is important not to move the packed column (like up and down) to avoid column cracks

Its also best to wet-pack the column. That reduces the odds of cracks or unevenness, and makes it quicker to pack. It is imperative to pack it properly by slapping the column with a rubber tube or anything of that sort.

..d in industral workers working in factories reeking of hexane for years on end. If your lab reeks of hexane i can understand the concern, but with the amounts used here, you're unlikely to get anywhere near the hundred ppm exposure limit at any point. I'd be ever so slightly more concerned about DCM bt even there it's not that big a deal, maybe move it to the fume hood on an exceptionally hot day.

Yeah, I also wouldn't worry about occasional exposures to small amounts of hexane like this. If you are still worried, just substitute heptane - it will work identically, but does not have the same neurotoxic effects and is also somewhat less volatile.
