That guy is not wearing a face mask or proper eye protection. You don't want to make a habit of inhaling iron filings. Do it in a well ventilated area, preferable outside. The fillings get everywhere, include into any vents of any other equipment you might have nearby. My glasses weren't enough to keep the filings out of my eyes. They are fine enough that they won't scratch or cut your eyes, but you will feel like you are having the worst bout of seasonal allergies you've ever had. I was sneezing rusty boogers for 3 days.
