Posted by Them That makes sense. Most of these places closed in the great recession, the oldest in 2009 and the most recent in April, so they haven't really been cleaned up much at all, but also haven't decayed *all* that much compared to some of what I've seen on here. The reason I was wondering was the number of full face masks left behind at Deferiet when it shut down in 09, whether those were there for a necessary reason that I should pay attention to, or if they were a cache for some disaster chemical or bureaucratic. At least asbestos is probably less of a threat in places from the 2000s, most of these buildings are essentially giant Quonset huts, built from steel framing and sheet metal walls. |
Posted by Samurai I work in an active Kraft Process paper mill (International Paper- Ticonderoga Mill, Ticonderoga NY)... |
To make ClO2, you need 57% hydrogen peroxide, 93% sulfuric acid, methanol, and compressed air |
Posted by Them So, 2(H2O2) + 3(H2SO4) + CH3(OH) = ClO2 how? Is that compressed air possibly pure chlorine gas instead? To add to the rogues' gallery of chemical nasties already named? |
Posted by siper Pardon my ignorance. So which cartridge would I use for PCB's? I'm currently using a 3m half-mask (6000) with a pink p100. |
Posted by Therrin Howdy Siper, I just went and researched the answer to your question. There's a few answers... The REALLY SHORT ANSWER! If your round pink filter is labeled P100 2097, you have adequate minimum protection. The Short Answer: Best Protection: 3M™ Organic Vapor Cartridge/Filter 60921, P100 Respiratory Protection http://multimedia....--&boundedSize=310 http://solutions.3...D0K8BC31gv%29&rt=d (P100 WITH Organic Vapor Protection, Pink Filter Face with Black Color Label) ______________________________________________________________________________ **OR** Intermediate Level Protection: 3M™ Particulate Filter 2097/07184(AAD), P100 Respiratory Protection, with Nuisance Level Organic Vapor Relief http://multimedia....--&boundedSize=310 http://solutions.3...D0K8BC31gv%29&rt=d Note: The round pink filters are NOT all the same!!! This one is a round pink filter labeled with number 2097. 3M makes SEVERAL round pink filters, each with different number codes, which are meant for different applications. Just getting a "round pink filter" does NOT mean you've matched it to the proper hazard. The Long Answer: Your question doesn't really ask enough. Exposure of PCB's (commonly chlorodiphenyl 42%/54%) is typically liquid above 50*F, and can be a solid/powder under 50*F, or can be found in ash/soot of incinerated materials. PCB's exposure routes are by inhalation, skin absorption, ingestion, and/or eye contact. So if you THINK you're going somewhere that PCB contamination may be a real problem, and you're only using a half-mask, you can still get pretty fucked up. PCB's cause a really nasty chloracne on the skin. Cancer Sites - [in animals: tumors of the pituitary gland & liver, leukemia] In such an environment, NIOSH suggests a SCBA apparatus in positive pressure or pressure-demand modes. For ESCAPE ONLY NIOSH suggest a FULL FACEPIECE respirator with an organic vapor canister having a P100 filter. So an organic vapor P100 would be the best option for very limited exposure. (This is not the same as a normal "P100" which is not rated for organic vapor). So it really depends what your exposure amount is. If you're in a location with very low level respiratory exposure, yes, you could spend a lot longer there with an Organic Vapor/P100 filter; but you really don't want that shit in your eyes or on your skin either. For additional information see the NIOSH page on PCB: http://www.cdc.gov.../npg/npgd0126.html My suggestion: For about $3 to $4 more you can get a "multi-contaminant filter" 3M™ Multi Gas/Vapor Cartridge/Filter 60926, P100 Respiratory Protection http://multimedia....--&boundedSize=310 http://solutions.3...D0K8BC31gv%29&rt=d (P100 WITH Organic Vapor Protection, WITH Acid Gas Protection. Pink Filter Face with Olive Color Label) (Everything mentioned on this page will fit the 3M 6000 series half-mask) Hope this helps you make a well-informed decision. |
Posted by siper You, sir, are an incredible man. Thanks! |
Posted by skatchkins Thanks Therrin for all the info on the different filters. I went with your advised 60921 for the added organic. Then I had to be "that guy" since I had some time on my hands, and masked off the inflow and painted the pink flat black. http://distilleryi...22000ae904e2_6.jpg May use my vinyl cutter to add a logo or something to the front. |

Posted by Therrin I never thought of doing that, but it does cut down on the pinkness of the whole thing. Something BioHazard-esque would be a nice touch for a logo. haha. You should put this up over on the Abandoned Nudes thread that I keep putting my nude ass-shots in-mines pics in. |
Posted by Ricky_from_TV And go shirtless for good measure right? |
