[EVENT] Uncovering a Lost Masterpiece: The Hidden Story Behind Paulus Potter's The Abduction of Europa ------------------------------------------------------------------------------------------------------------ 1.From: Kathryn Makos Posted: Saturday May 17, 2025 6:49 PM Subject: RE: Fume extractor recommendation Message: Greetings, In addition to Monona's always excellent advice, I want to add this: your local Fire Department &/or if you are affiliated with the State, your state fire protection engineering team (Authority Having Jurisdiction) will probably forbid the use of a ductless fume hood for flammable vapors, even when fitted with the appropriate organic vapor filtration, because there is no guarantee the charcoal filters don't leak around the edges or will leak once saturated. This would be based on Building Codes and any additional State design codes. Per Monona: Ask if the NCMA has a Health & Safety consultant on contract for this design decision. I cannot tell from your website if you are literally a State Museum or just have NC in your title as a private museum, but if a State then they also have OEHS staff to assist. Another option would be to talk with the North Carolina On-Site Consultation Program. OSHA has always had a non-regulatory small business assistance program in every state. It is completely free, you can request a consultation on a targeted issue, and the only agreement is that a business work with OnSite to mitigate the hazard. They should have CIHs as well as Fire Protection specialists on staff who can work with your facility engineer on the proper system for you.

So dust, smoke particles, and fumes are all particles. Notice there is no mention of solvent VAPORS. These solvent vapors are molecules, not particles. They require a filter medium on which to adsorb such as activated charcoal. The charcoal can be activated to capture specific vapors or gases such as some organic vapor solvents, gases like formaldehyde, etc. But no charcoal will capture all of your solvents and the rapid movement past the filter medium will limit capture. And that is IF, AND ONLY IF, they also provide some charcoal in your filter system. This system is not a good choice for the purpose for which you intend it. Choosing a filter system the exhausts out a window should be should involve many people including the engineer who runs your HVAC system. For every cubic foot of air you exhaust out a window, that HVAC system must provide another cubic foot to replace it. These systems can unbalance the whole building's ventilation. If you have a significant amount of solvent processes that need to be addressed, I suggest bringing ventilation experts (CIHs with P.E. credentials for example) who can design a system or install a chemistry fume hood that will be compatible with changes in your HVAC and meet the existing air quality regulations, building codes, and fire regs in your area. Monona Original Message: Sent: 5/15/2025 4:25:00 PM From: Perry Hurt Subject: Fume extractor recommendation The North Carolina Museum of Art Conservation Department is planning on purchasing a mobile fume extractor. Currently we are interesting in the Extract-All SP987-5-2A Dual Arm Portable Air Cleaner, SP987-5-2A Dual Arm Portable Air Cleaner - Air Impurities Removal Systems <https://www.airsystems-inc.com/products/fume-extractors/sp987-5-2a-dual-arm-portable-air-cleaner/>. Does anyone have insights on this model, or other suggestions for fume extractors? We are looking for a compact fume extractor, mainly to filter organic solvent fumes that commonly result from cleaning and retouching artworks. It's been suggested that the two-arm variety are particularly useful to cover both the artwork being treated as well as a taboret where solvents are being accessed. Like many mobile fume extractors, this Extract-All model has a replaceable internal filter. We would also like to have the option of venting fumes outside, out a window for example.

A long-lost monumental painting by Dutch master Paulus Potter has been rediscovered - thanks to a 1664 newspaper announcement! A collaborative research project between the National Gallery of Ireland and the Mauritshuis, The Hague, has combined conservation, art-historical, and scientific analysis to confirm that Head of a White Bull is a fragment from a larger composition by Paulus Potter, the renowned Dutch animal painter of the seventeenth century. This finding sheds new light on Potter's exploration of mythology. This revelation not only expands his known oeuvre but also challenges the long-held belief that his genius was confined to animal depictions. Muirne Lydon and Natalia Macro from the National Gallery of Ireland will join us to share more about this fascinating discovery. Will we see you there?
