Yeah could be a swelled battery leaking . But room should smell like rotten eggs ! :shrug:

I would touch the goo with a tool and see if it is sticky or pliable. Had MANY of those old 400 series cards that used a green encapsulent over the face of the cards that had runs that closely resembled a leaking component. It was used as a moisture proofing for the boards. If it is hard as a rock it's probably the coating.

This appear to be a 620 panel --- the drip is hanging under the rack for the 400s and above the fuses.

This has to be something to do with an outside source dripping through, not produced by the 400 units.

Good catch Ken. I didn't see the drips on the panel only on the far right card breaking up the red border. After your info and reviewing with one eye shut and my beer put put away I see the mysterious green goo. I notice it is on the same place on the panel beneath apparently the same model card. HMMMMMMM.

Couldn't hurt to pull the card and take a look at it.

Leakage from older electronic components is not that uncommon, I have seen it on 1A2 cards, and cards from several switches. This is normally a sticky goo that is almost impossible to clean up. If the equipment is still in service the best thing is to replace the cards that are leaking. If they are still working they will fail.

thanks for all the replies.

We are sure that the panel is not in use, and I do not think there is any planned use for the equipment. The overiding issue is - " is the green liquid hazardous in some way, relative to personal exposure or disposal."

Since no one at the location knows what it is, they prefer to figure it out (if possible) instead of assuming it to be "safe".

That leaves me, a non-telphone tech person and about the same age as the equipment, to see what I can come up with. It is obvious that many of you are extremely familiar with the components and I appreciate the feedback.

I think it is soap from an upstairs bathroom. Sliding down the plumbing inside the wall till it found an opening in the phone room, worked its way through the back plane and out the front of the card. Scrape it off, put it in a cup of water and shake it, or give it to someone else to shake if you so choose.

After all your research and hard work, I'll bet you find that "goo" to be safer to touch, smell and probably eat then it is to follow a bus down main street and sniff the fumes.

Ok, now worry. It just dawned on me that the little metal 'reed' relay sometimes had MERCURY wetted contacts! That's the metal can about 1-3/4 inches log and 3/8 inch square on the rear half of the board. On the blue front 400D card, it's the "animal" with the white 'Y' stenciled over the part number.
