I just had concerns of bottle bombs, myself. I brewed up a hefeweizen, which, by style, has more carbonation than typical ales. So, I carbed per the style, not realizing it may be an issue with pressure in the bottles. If you look around, you'll see information stating not to go too much over 3 volumes of CO2 in bottles. (Has to do with how much dissolved CO2 is in the beer for carbonation, and what that volume of CO2 would look like not dissolved in a liquid.) I carbed to somewhere around 3.6 volumes, which is considerably higher than recommended. Maybe I've gotten lucky (probably the case), but I've had zero bottle bombs, thus far. I'm still leery of opening them, but I've kept them cool in the basement, at around 65°F, which will help keep the pressure down a little. And I always chill in the fridge before opening them.
With normal carbonation rates and full fermentation, I'd say you're just fine. Typical carbonation rates only sit around 2.5 volumes.
Here's some info on carbonation:
