We have come across 2 red comet Fire Extinguishers (one c. 1940 and one c. 1920) while unpacking our collection and they are still filled with what is most likely carbon tetrachloride. Any advice on how other institutions have handled disposal/display/storage/replication of these? Thanks! Heather -- Heather Pozun Watson Director, Fremont Co. Pioneer Museum 1443 W.
