Generally base baths for cleaning purpose are kept outside, close to the sink. They should be covered properly using an appropriate lid. If lab has additional chemical fume hood (extra, dedicated to baths), bath could be placed inside chemical fume hood to prevent the spill and chemical exposures to the researchers. Base baths are generally big in size, and difficult to accommodate inside chemical fume hood while researcher is using the same hood.
We frequently see base baths located outside of fume hoods. If they are covered and secure we haven’t objected to this in the past.
What are your opinions regarding placement of base baths outside fume hoods, near sinks, and on the floor in 5-gallon buckets?
