We used a mixed-method approach of quantitative household spot checks for hygiene indicators and qualitative handwashing demonstrations, interviews, and focus group discussions to characterize handwashing practices among GEMS caretakers and confirm that spot check indicators were valid proxies for handwashing practices.
23, 24 To support the use of these spot-check indicators in the MSD study, our second objective was to conduct qualitative studies to characterize the use of hygiene materials among GEMS caretakers and confirm that observed materials were commonly used for handwashing purposes.
When pierced the pH of the extruding fluid was checked with indicator paper, the checked fluid was in all cases neutral (pH 7), indicating that the possibly dissolved alkalis are balanced by chlorine.
When pierced, the pH of the extruding fluid was checked with indicator paper; the checked fluid was in all cases neutral (pH = 7), indicating that the possibly dissolved alkalis are balanced by chlorine, that Al acidic and basic species are negligible and that neutral complex such as NaAl(OH 4 may form.
