Electrolytic capacitors can explode if wired backwards (tantalum caps are notorious for it). You're fairly safe if power is off when you open the box. I would recommend gloves if you plan to handle them them...while the electrolyte is usually not very toxic, there are some that use a mildly caustic solution and may burn sensitive skin.
