In *some* respects, tantalums are no more hazardous than any other component if selected or installed incorrectly. What tantalums do that seperates them from other components is the way in which they can fail. One way is in the short term. If under whatever the circuit conditions are they are installed backwards, they explode are flame up. Or they are installed correctly but they are marked incorrectly. Another way is long term. Either they can again be installed backwards and NOT fail for some long period of time out in the field. Or, they are installed correctly and fail with by - 1) having too much ripple current, or 2) being selected to have their operating voltage too close to the working voltage, or 3) everying else is correct but the environment forces them to degrade far faster than expected and fail simply because they have aged in some accelerated manner such as a high heat environment.
