DCHAS-L Archives Oct 28 2010 - Re: Lab safety showers

I am currently involved in construction of two new laboratories and was instructed by the city commercial building review department to include a 1 " high curb around the shower area to keep hazmat from entering the floor drain in the event of a spill. Also, the curb has to be sloped on both sides to allow accessibility. -- Best regards, Betsy Shelton 512.636.1905 retrosynthesis**At_Symbol_Here**gmail.com On Tue, Oct 26, 2010 at 9:50 AM, Gordon Kroemer wrote : > I use a 55-gallon drum, too, but have installed a small pond pump with a > hose that can be run to where needed.
