    ground for an open delta

    Bill, Thanks a lot for your detailed response. A "Winnipeg" connection huh? I've never heard of it, and I'm from Winnipeg. Alan

    ground for an open delta

    I am working on a project at a remote site that has only two phases supplied via an overhead line across a mountain range. Adding the third phase is very expensive. So there is an open wye/open delta 600V power source created from the two 12kv lines. How is the grounding usually done for an...

    Hazard Classification of PAX (KAX)

    In case anyone else has this situation, the supplier of KAX 51 told me that it will generate CS2 above approximately 30C. Even though KAX 51 in liquid form is non-flammable, the factory is rated Class I, Div I. Scary stuff. Alan

    Hazard Classification of PAX (KAX)

    I found out a bit more today. The solution is a 30% concentration and is not flammable, according to the supplier. They also said it did not have to be very hot to give off CS2, and they will confirm the actual temperature asap. But since CS2 has a flashpoint of -30C, and an LEL of 1.25%...

    Hazard Classification of PAX (KAX)

    cdafd, there is an MSDS for it, but this doesn't cover the NFPA classification. And yes, liquid is the final product form. rbalex, thanks for your information. The question I am wrestling with is whether to assume that carbon disulphide might be generated, or just to ignore it and deal only...

    Hazard Classification of PAX (KAX)

    Thanks for your reply. The material is supplied in powder form, but it is dissolved in water for the process. I am only concerned about it when it is a liquid. It seems to be relatively safe unless it is heated, in which case it gives off carbon disulphide vapors which are highly flammable...

    Hazard Classification of PAX (KAX)

    Hi, I am doing a Hazardous Area Classification for a site that uses Potassium Amyl Xanthate (PAX or KAX). I have the MSDS sheet, but I can't determine which NFPA Group it should be listed in. I assume Group D, but I'd like to verify. I don't have NFPA 325, and it is no longer available...
