Hello Listers - I am looking for experiences, anecdotes, opinions about the necessity of a fume hood in an archaeology laboratory setup. The laboratory in question will have a general exhaust fan as well as Nederman extraction trunks for targeted fume removal. A fume hood is also planned, but I'm beginning to think it may be redundant. Some conservation entailing the use of chemicals will occur in the laboratory, but that is not the primary purpose/intended use of the space. (The lab supports a resource management and research-based government archaeology program.)
