I have an MSDS for "Carbon Monoxide, Carbon Dioxide and Propane in Nitrogen." and I'm looking for a new one. The MSDS# is obscured by a BAR-84 sticker. The Lot# is 827502, if that helps.
I saw 3 MSDSs in the Library for this mixture, but none of them had this ratio of ingredients;
Carbon Monoxide 1.2-8.0%
Carbon Dioxide 4.0-16.0%
Propane 600-3200 ppm
