Yeah, these past few days I would say I've probably got my daily FDA requirement of lead additives, but I'm pretty good about washing my hands every single time after working on it before I eat or smoke. That darn old conveyer chain lube you wear for days though...unless you wanna get some Comet and take a couple of layers of skin off.. |:>( I also do my de-drossing in the evening AFTER everybody else has left, WITH my face filter on...bad part about doing it late like that is that my breath isn't the normal sweet scent of ambrosia that it is in the morning.. (:>D (you learn that real quick when you put a face mask on!) One thing I remembered to do when I had the ducting for the wave exhaust installed back when we opened up 'bout a year ago, was to run a short length of duct off to one side of the main duct at the exit end, and had a hood made a little bigger than the solder pot. When you crank the pot out the hood is right above the pot. I had them put a butterfly valve in the main duct just below where I put the short section. I could close it and divert all the suck to the solder pot hood. When I'm de-drossing I see can any dust generated go right up the exhaust...so I'm not spreading it all over the production floor...let the pidgeons on the roof deal with it, they've pooped on my car anyway...(hmmmm, thinking about it, maybe that's WHY they're pooping on my car!) Actually, I don't think much dust gets out, I'm pretty careful about not making a buncha dust, and what does go up the exhaust probably sticks to the flux residues coating the inside of the duct. One last thing on fume extractors, until I worked for Zevatech, I didn't really think too much about how the machines were exhausted at shows like NEPCON when I attended. But then after working a few shows I became very impressed with Impell systems. That's what's used to exhaust everything down at the TAC line. Their systems make a lot of sense once you look into them. No holes in the roof, can move your line anywhere you want, lower air conditioning costs...something to think about. Only reason I didn't exhaust using Impell here was that there was an existing fan on the roof and it was a little bit cheaper to go the traditional route...couldn't quite convince the powers that be to spring for a few more bucks. (I'm convinced it would have been cheaper in the long run though) -Steve Gregory- ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
