Yep! I have not arced over in several years.

I find myself wondering what might be the results of _my_ exposure
to all manner of industrial and laboratory chemicals over a lot of
years.

Back when I worked a lot of radar, countermeasures, and big RF stuff we
would get a drench of Cooliol 50 or 75 cooling oil every once in a while.
Clean up? we used trico or industrial freon. Am not sure of the results yet
but the last time a UFO came close they did a U turn.

have tumbled out of position, and you had to reach your arm down into the
Arochlor to unjam the rack and fish out the stray capacitors.

dioxin hadn't been heard of and you could survive a nearby 10 megaton blast

PCB's was what has protected me from any damage from high-power RF fields
all these years.

Around 1957 I went to the Southern California Edison yard in the
industrial area
of Santa Barbara.

In the office I paid a couple a dollar or so for a gallon of transformer
oil and
took my gallon can and followed one of the men outside to a 55 gallon
drum. The
whole area was oily, dirty and looked like it'd been used for years. Some
areas
of the ground looked as though they'd been paved with oil. We opened the
valve
on the can and filled the can. Then we both wiped the spills and splashes
on
our hands and the drips on the can off using a very oily rag.

When I got back to my 1947 Chevy I put it on an old rag in the trunk of
the car
in a cardboard box so it wouldn't tip over. I wiped my oily shoes on the
dirt
at the edge of the road so I wouldn't get too much oil on the rubber floor
mats.

When I got home I poured the oil into the Heathkit Cantenna can and had
some
left over. A few years later I poured out the remnants from the can onto
the
ground in the area where our oil drain pans were inverted to get the gunk
out of
them and threw the can in the garbage.

In following years I put the dummy load on the floor under the operating
desk in
a pie tin to keep any seepage from getting on the carpet and floor. I
wiped it
off several times over the years with paper towels.

Since all my fingers have fallen off - I'm typing with my toes - and now
need to
wear glasses and my eyesight isn't as good as it used to be.

Do you think this is a result of coming in contact with PCB?

I have an old Heathkit Cantenna dummy load. how can I tell what its
filled
with, Transformer oil (pcb's) or Mineral oil... sounds silly but it
just
started leaking and I have oil all over the work bench... I went to a
paint
store and got another gallon can and that took care of the leak. hi , but
it was about half empty.

Yep, them PCB's are officially nasty little chemicals. .....

1: pour contents into empty coffee can

2: replace coffee can lid

3: gift wrap same

4: place on car rear seat, leave window down

5: go have a beer or three +/_ 45 minutes

6: go back to car, wipe seat where can was

7: go home or
7b: have another beer to celebrate empty rear seat

Hazmat is easy !!! ~8^o

The oil could be most anything, since the Cantenna was shipped dry, and the
buyer was instructed to fill it with mineral oil. What the PO really poured
in there is the real question. Since most consumers didn't have access to a
gallon of PCB (Monsanto's Arachlor), it likely isn't a PCB. But who knows?
One easy test is that a PCB won't burn, where engine oil or mineral oil
will. Wet a small piece of paper towel with the unknown oil, and try to
light it (away from the main body of oil!). If it won't burn, then its PCB.

Imagine the repercussions of knowing you had leaked a half-gallon of PCB in
your home. You have now created an official toxic spill, a hazardous site
which now must be properly decontaminated. If you think asbestos remediation
is bad news, just wait till the hazmat guys are into your PCB zone.
Remember, those PCB's love water, and they don't break down (short of oxygen
incineration), so you have a lot more than just a workbench that has to go.
You have got that stuff all over your hands, and your clothes. Where did you
wash your hands? Oops, now your bathroom is also contaminated. So's the rest
of your house. How did you wash your clothes? Looks like you'll be needing a
new washer / dryer. And where did that PCB contaminated laundry water go to?
Probably have to dig up your sewer pipes and haul them off too! Not to
mention that you have now contaminated your entire municipal sewerage
system! Get ready for some interesting fines and new legal exposure.

Did you shake hands with anybody lately? You've been spreading trace amounts
of PCB's everywhere. And what is the maximum allowable "safe" level of PCB
contamination? Parts per million? Parts per billion? You'll wish you were
dead. But even so, since PCB's also love fatty acids (they just love to hide
in the fat cells of your body), your carcass is also contaminated. You're a
walking toxic waste dump. You probably meet the criteria for needing an MSDS
just to drive to work. (Did I mention that you also have contaminated your
workplace?) So even an embalmer wouldn't want to touch you, and what
cemetery would accept an officially contaminated corpse?

Nope, looks like cremation is indicated. And I'll bet there's a wild
"Catch-22" waiting for you. I'll bet that a human crematory won't accept a
"toxic waste" contaminated corpse, and a toxic waste incinerator isn't
licensed to accept a human corpse. Gotcha! Maybe a Viking funeral?

Yep, them PCB's are officially nasty little chemicals. Just ask Dow
Chemical, who's still paying to dig up Hudson River mud and move it to
somewhere else that isn't the Hudson River (and that "somewhere else" is
another story).
