If it helps, we don't have any floor drains in our labs under safety showers. We use a trash can and funnel curtain to do the flushing on the safety showers as required. I can count on one hand the number of times the shower has been used in my 20+ years here and when it does, we have had custodial come in and use their large water vac to clean-up.

Good afternoon,
Quick query. We have a new building with labs under construction and near the final phases. Ammonium Hydroxide (corrosive) will be used in a ventilation hood in one of the lab rooms. There is a sink mounted eyewash planned but I just
found out that no provisions were made for a safety shower. This has now been brought to the attention of the construction group but unfortunately there is no floor drain in that lab room and it's beyond the point where one could be installed. The group
is suggesting a location for the shower that is accessible within 5 seconds of where the chemical will be used but the individual would have to proceed through a swinging door. Under ANSI Z358.1 a door is considered an obstruction for corrosive hazards.
Would a swinging door still be considered an obstruction? Any advice would be great.
