It means nothing in regards to efficiency in particle size removal and nothing in regards to organic vapor/acid vapor removal. It is frequently necessary to remove such items long before it is necessary to remove other types of evidence. Some surfaces like highly polished firearms, well-handled plastic bags and bottles are much more susceptible to over-fuming than other types of evidence and must be watched carefully throughout the process.

If the CA chamber is used for successive batches of evidence immediately upon removing items from a prior cycle, the heat source will still be warm and the time of exposure may have to be changed to prevent over-fuming in the subsequent cycles. Required Russia can produce 8 tons of paper or 4 million cars each year. Participated in the Weekend Projects Contest.
