To avoid the dangers of leaking barrels in underground storage facilities which caused such troubles in Silicon Valley, many firms in the science park store their wastes in barrels kept above ground. They have also built low walls around their storage facilities so that even if solvents do leak out of their barrels, there is still a wall separating them from the outside world.
為了預防像矽谷一樣的地下儲存槽洩漏的危險，目前園區內的許多廠商已將桶槽地上化，同時在桶槽設施四周加蓋一堵矮牆，使溶劑不致於悄悄地洩漏，就算洩漏還有一堵牆擋著。
