The fieldwork was carried out by a main researcher and a team of 10 locally recruited field investigators. Waste generation data were recorded over three shifts (4 am–12 noon, 12 noon–8 pm and 8 pm–4 am) on each of three days in a week (two weekdays and one weekend) in each HCE. The field investigators placed a designated bin-bag in each ward or department at the start of a shift and collected the bag at the end of the shift, replacing it with a new one to continue the survey program. The bin-bags were individually weighed using a hand held scale. Then the waste was manually segregated (following appropriate safety precautions) into two categories (hazardous or non-hazardous) as designated in WHO guidelines (Prüss et al., 1999) and weighed again. Each investigator received training on how to measure the waste quantity, on safe operation during segregation of hazardous and non-hazardous waste, on replacing bin-bags and on data recording procedures. This method was applied to all departments of each HCE, including both
of the official mortuary departments in the study area.
