| Abstract |
Slip and fall accidents in bathroom and bathtub have several causes, but they are especially common when there is soapsuds on the floor
during a shower. Despite this situation, it can be said that there is a insufficient of standards on surface contamination materials used in
bathroom floor slip resistance testing. In this study, as the surface contaminating substance which is alternative to the soapsuds in bathroom,
the aqueous solution of SLS was experimentally derived using the proper concentrations. As the research method, first, the questionnaires
were used to standardize the soapsuds, the consumption of the body wash and then the concentration of soapsuds used during the actual time
of shower was analyzed. Second, a slippery test on 10 floor-covering samples were conducted using 9 types of soapsuds to get the C.S.R·B,
the coefficient of slip resistance when taking action barefoot. Third, C.S.R.B were measured using 6 concentrations (0.05%, 0.1%, 0.2%,
0.5%, 1.0%, 1.5%) of SLS aqueous solutions, and the concentration of SLS aqueous solution which is well harmonized with the C.S.R.B of
body washes was obtained. The study conducted with the processes described above showed that 0.1% SLS aqueous solution was the surface
contaminating substance which is similar to the soapsuds generated during a shower. |
