Another additional safety measure is to TEST each cap before you use  
it.  Maybe at the rated voltage or twice that even.

I worked at a company (Teradyne) that made (still makes) highest  
quality automatic test equipment.  They tested EVERY component they  
used before it went to the stock room.  Every one. Here is why:

Cost to test a resistor or transistor:  nearly zero
Cost to find a bad transistor after board testing stage:  $18.65
Cost to find it after it fails at the customers factory:  $367.00 or  
more

Of course, the company made test equipment so they used their own  
products to do the testing.
