Safety issues? Yes, two.
First, it is powerful enough to do serious damage. Don't shoot anybody with it.
Second, and this is true with ALL airguns with the sliding pump cylinder, it is considered prudent to hold the cocking lever with one hand while loading the pellet with the other. If the sear were to fail and the gun try to fire while the breach was open AND your fingers were in it... it'll seriously injure them. This is also true of the Fast Deer, the Xisico B3/B7, the QB88, the B4-2, etc.
The up side is that the gun probably isn't powerful enough to actually cut your fingers off, unlike rifles like the QB36-2 or the B21/B30.
The wood is touch and go on these. When I stripped mine (bought 3-4 years ago), I found one of the nicests pieces of wood I'd ever seen on a Chinese gun. But the wood on my B4-2 was pretty poor.
