As removed from vintage USA Military radio equipment
PRODUCT SAFETY NOTICE:
It is extremely likely that the dielectric oil in this capacitor contains PCB's - production and use of PCB's in new equipment has been banned worldwide since the 1970's
This capacitor MUST be handled with care and in the event of ANY leakage, this capacitor must be treated as an item containing chemicals which are hazardous to human health (carcinogenic).
NEVER EVER TOUCH ANY LEAKED LIQUID
NEVER DISPOSE OF THIS CAPACITOR IN HOUSEHOLD WASTE!
PCB's were in very wide use up until the late 1960's, especially in products such as these capacitors.
Here is a link for very detailed information about the chemical compound, its dangers and recommended disposal of components containing PCB's
