Oil-filled capacitors.

[rayfri]

I just toss them out in the garbage can to be picked up every Friday.   
There's questions now if PCBs are really that hazardous or not.
And any small amount inside one isnt anything worth freaking out about .....
To quote the Bard.... "the sound, the fury, signifying nothing..."    HI 
HI.    Maybe we need to start worrying about the flourescent material in 
our watches that make them glow in the dark...???   Radiation is 
accumulative you know....
Personally, I think we need to spend out time worrying about things that 
really ARE dangerous .... not freaking out over
every little inconsequential thing that comes along....   
But . .that's just my opinion.....   and everyone has their own and are 
welcome to theirs.
