My only experience with floor drains has been negative. - In that particular instance (an laboratory explosion involving approx. 200 ml of nitric acid), the drench shower worked but the floor drain did not. - Having saved the eyes and skin of the person involved from the acid burn, the group responding felt it was definitely preferable to clean up the water than not have a shower at all. - Post incidence review indicated that, over the years, the drain had become plugged from lack of maintenance. Floor sweeping had led to the construction of a plug of dirt under the drain cover, thereby leading to a blocked drain. - Ever after, I have always recommended the installation of drench showers in chemical laboratories. The installation of drains should be done only if it can be done both economically and properly. In the end, however, a drain, once installed, will only work if it is properly maintained. - *********************************************** * Dr. R. E.
