In many developing countries the conditions under which most of the workers in informal enterprises operate are precarious and unsafe. Many workplaces in the informal sector have some inherent hazards. Multiple exposures to different hazards are mainly due to poor housekeeping and congestion in the workplaces. Occupational hazards lead to negative health and economic consequences on workers and on other persons in the proximity of the working area. In this study occupational hazards and their associated impacts on metal workers in Nakuru town is assessed. Data was collected by a combination of questionnaires, observation and measurements at various Jua kali workplaces. The study is carried out through surveys and observations in workplaces. The study shows that cutting, impacts and crushing are the most common mechanical hazards while welding fumes, paints and solvents are the main chemical hazards in many Jua kali establishments. The use of uninsulated cables or cables with worn-out insulations was seen to be the leading electrical hazard. In regard to work related illnesses, fatigue, periodic headaches and lower back pain were seen to be the most frequent. Occupational injuries in this sector include cuts, punctures and hearing impairments. As relates to economic impacts, it was established that many workers have occasioned property damage as result of workplace incidences. The study shows that the micro and small enterprises in this informal sector are burdened with a wide variety of hazards which are related to their activities. The results of the study showed that majority of Jua kali artisans have little knowledge and training in occupational safety and health. From this study, it is seen that there is need for interventions such as trainings to improve health and safety awareness and welfare among Jua kali workers.
