INTRODUCTIONWork related safety and health hazards are a major public health concern worldwide and are under-researched especially in low and middle income countries. 1 According to the World Health Organization (WHO), 58 percent of the global population spends one-third of their time at work during adulthood.2 Therefore, the issue of work related safety has gathered increasing attention in the public health domain. The prevalence and incidence of injuries and deaths have gradually risen over the years -approximately 0.9-2.3 million work related deaths were estimated by the International Labour Organization (ILO) worldwide in 2003.3 Furthermore, the ILO reported in the same year that there were an estimated 358,000 fatal occupational accidents, 337 million occupational accidents and 160 million occupational diseases worldwide. 4 Higher prevalence of injuries and death were ABSTRACT Background: Street sweepers play important roles for keeping the cities clean. Their works entail removing of debris from streets, collecting solid waste, disposing and recycling waste material. Consequently, they have higher chances to be exposed to numerous risk factors; therefore, their occupational safety and health hazard became crucial. There is little evidence about the sweeping practices, perceptions and knowledge on their occupational safety and health hazards. The objective of the study is to explore current sweeping practices, perceived risk and the level of knowledge of a group of street sweepers of Dhaka city. Methods: An explorative qualitative research design was used. We conducted 15 IDIs, 8 KIIs and 5 FGDs with Telegu street sweepers, community and religious leaders and NGO workers in two different sweeper colonies in Dhaka City. Results: Due to the manual handling process, the street sweepers are often exposed to a variety of risks factorsexhaust fumes, extreme noise, toxic substances and dust particles. Frequent infections and injuries were reported commonly as they lack basic safety equipment's during works. Low perceived health hazards were prevalent. Strong faith-based explanations were found to rationalize possible health hazards. Conclusions: A number of socio-economic factors influence the level of knowledge and risk perception. Interventions on awareness building program coupled with behaviour change counselling (BCC) activities would be appropriate to address the lack of knowledge on health hazards and low risks perception.
