An environmental chamber comprising a transparent dome shaped housing (12) having an annular conduit, including an exhaust port, affixed to the base of the housing. The housing fits over an end of a chemical container (68), to create a controlled environment within the encapsulated space between the housing and the container. Two openings (44, 46) at the top of the housing allow chemical transfer hoses (76, 78) to be connected to the chemical container openings. A pair of gloved access ports (48) allow an operator to access the encapsulated space to manipulate connections between the transfer hoses and the chemical container openings. The top of the housing includes an intake port (42) for delivering clean purging material into the encapsulated space to purge any chemical that escaped from the chemical openings during hook up of the transfer tubing. A sensor (38) may be included for warning of a chemical leak within the protected environment. |
