の中に以下の文章があります。
CAUTION:
IT IS ALSO STRONGLY RECOMMENDED THAT AN EMERGENCY GAS
SHUTOFF VALVE BE PLACED JUST OUTSIDE THE CLEAN BENCH ON THE
GAS SUPPLY LINE.
All NuAire clean benches meet the safety requirements of UL and CSA for Laboratory Equipment. To comply with these safety requirements, NuAire uses only certified gas valves. In addition, if external
piping is required, only black pipe is used for this application.
As previously stated NuAire doesn't recommend the use of natural gas within the clean bench and ASSUMES NO RESPONSIBILITY FOR ITS USE. USE AT YOUR OWN RISK. The Bunsen burner flame within the clean bench disrupts the laminar air stream, which must be maintained for
maximum efficiency.
まあ、だから使っちゃだめではないのでしょうが、どこでも一定の不安と不合理を感じているようではあります。
私の興味は、日本のメーカーは、製造者責任の観点からどのように対応しているのかなあということ。 |
