Good news and... Not quite bad news. First, this is a modern flash with a low trigger voltage, and there is no risk using it on any modern camera. So, good news.

Second: this will work with any generic radio trigger, from cheap to expensive. However, its headline feature is built-in radio triggering, and that works with Yongnou's own triggers, which they only make for Canon and Nikon.

I found a post on modifying a Canon trigger to work with Olympus, which seems a bit scary to me but may work for you.

An alternative might be the Cheetah Light V850, which also comes with an integrated (in this case, clips on the side of the flash) radio trigger system. It is completely generic, using only the standard center pin, but the cool thing is that you can set the power from the in-camera transmitter, so it's easy to make the manual adjustments — just test and terak until you have it right. You can fire multiple flashes, and actually have up to 16 sets with independently-set power levels (There's a dial to select groups quickly).

One downside is that this has a less-reliable 400mhz radio rather than the 2.4ghz band that Yongnou uses (I haven't had trouble in practice, but I haven't pushed it). Also it uses a rechargeable lithium battery, which yields amazing recharge times, but if it runs out, you can't just pop in drugstore AAs.

This flash is also sold as the Godox V850 and Neewer TT850 — read reviews at Fstoppers and FlashHavoc. The Cheetah Light brand is slightly more expensive, but you get a one-year warranty and US repair (rather than sending directly to China if there is a problem).

Or, you could of course go with the Yongnou you are looking at, or one of the other models Yongnou makes + Pocket Wizard triggers or whatever you like. I think, though, that if you are not using one of the big two camera systems, Yongnou isn't the best choice.
