SMPTE NY MEETING 17 January 1996:

The first speaker was Ed Kurz of Kodak.  Ed described several 
aspects of film care:

1. PREVENTION: Keep the process dirt to a minimum by proper handling 
and laboratory procedures.  Ed noted that one of the biggest culprits 
in post-lab dirt was paper and cardboard; their rough edges often 
allow particles to disengage and land on film.  So use plastc bags 
and other non-fibrous handling methods. Keep clear of paper products. 

2. MECHANICAL: Remove surface dirt and dust with brushes, vacuums, 
ionized air, PTR, etc.

3. AQUEOUS: Water-based cleaners and wetting agents of various sorts. 

4. ORGANIC SOLVENT: Traditional solvent cleaning, which can be 
characterized by the following (assuming proper solvent):

   Solvent Action (dissolves oils, fingerprints)
   No Residue
   No Photographic Activity
   Fast Evaporation Rate (drying time / film speed)
   Low Toxicity

Ed also presented a summary of various solvents, but concentrated on 
comparisons of MC, Perc, HFC 43-10, IPA and AK-255.  The details are 
too numerous to reproduce here, but they can be found in other sources 
(and if you really want them, I'll send them separately).

The second speaker was Jonathan Banks from RTI/Lipsner-Smith. He is 
new to the US operation (having spent many years in the UK operation) 
and will be taking over the Chicago operation.  Jonathan presented 
2 solvent based solutions in the form of the 900 (IPA) and MK-VI 
(MC) machines.  He also made some addressed the value of the film; 
the importance of the data it contained, and related that to the 
choice of cleaner (equipment and methodology).  He als raised some 
interesting points about archives.  For example, unlike (most of) us, 
the gov't has archives of nitrate films, so an IPA-based cleaner is 
not appropriate. 

The third speaker was "Mike" Michelson of TFI who described the TFI 
FC-2000/4000 aqueous cleaner.  The tech description was pretty 
straightforward, but there seemed to be (imho) an undercurrent of 
commercialism to his presentation.  There wereno revalations here, 
you can get the same info at any trade show or from the product 
literature.  One point Mike made was that his cleaners did NOT 
address solvent action (i.e., will not clean oils and fingerprints) 
but that this "extreme" condition represented a small fraction of 
everyday bulk cleaning needs and therefore was considered unimportant 
to the design of an aqueous system. 

The fourth and last speaker was Don Wannamaker of Environmental 
Management Ltd, a company which deals with the legal aspects of 
compliance, both OSHA (for safety and health) and EPA (for the 
environment).  If nothing else, Don made it clera that this is 
treacherous territory and that anybody who navigates these waters 
alone is bound for trouble.  In a few short minutes, our heads were 
reeling from the regulations and cross-regulations, classifications, 
compliances, blah blah.  The most enlightening thing for me was to 
learn that aside from all the OSHA and EPA stuff (daunting enough), 
the STATE or LOCALITY can enforce rules above and beyond the OSHA 
and EPA rules. Ouch. Especially for our major markets (LA: smog 
valley, NYC: density issues, especially as pertains to ozone).

Well, after that we all needed margaritas (which have been shown to 
have a negligible ODP and only moderate toxicity) so we retired to 
an appropriate venue where we all sobbed in our drinks over the loss 
of 1,1,1 and were consoled by the generosity of our hosts (Kodak) and 
the other participants in the meeting.
