Hi All - Is anyone aware of a prohibition against using 45 degree angle ductwork runs (as opposed to vertical runs) for a perchloric acid fume hood? This pertains to water washdown systems. This question was posed to me and I thought I'd seek your collective wisdom. I'd appreciate it if you could point me to any references you may be aware of regarding this subject. Regards Larry
