“…While a majority of them were aware of these hazards (53.7%), a significant proportion still lacked awareness (46.3%). This finding is supported by previous study conducted by Mutangala et al (2021) in Congo, Africa. 91% of the worker were aware about noise induced health hazards.…”

Background: Occupational exposure to noise is a significant concern in the welding industry, posing potential health hazards to workers. This study aimed to assess the prevalence of noise-induced health hazards, knowledge regarding these hazards, and the practice of preventive measures among welders in Mysuru City. Methods: A cross-sectional study was conducted and data was collected from welders in Mysuru City, including noise exposure levels, perceived stress levels, insomnia prevalence, and demographic characteristics. The association between the number of years of noise exposure and auditory/non-auditory health effects was analysed. Participants' awareness of noise-induced health hazards and the use of protective equipment were also evaluated. Results: The study included male participants, predominantly below 30 years of age, with a majority (74.3%) belonging to the Muslim community. Decreased hearing (11.5%) and sleep disorders (3%) were reported by participants. About half (53.7%) were aware of noise-induced health hazards, with a high usage of safety glasses but limited use of earplugs. Most had exposure to noise for less than 5 years. Moderate levels of perceived stress and low prevalence of insomnia were observed. Significant associations were found between the number of years of noise exposure and both auditory/non-auditory health hazards, as well as between age category and auditory health effects. Conclusions: The study reveals the prevalence of noise-induced health hazards among welders in Mysuru City and highlights the importance of promoting occupational health and safety measures. Raising awareness and encouraging the use of protective measures are crucial to mitigate the adverse effects of noise exposure in the welding industry.

IntroductionThe multiple constraints of urban agriculture have prompted farmers in Lubumbashi to turn to informal mutual aid networks. The survey data collected from 88 farmers chosen at random from the 202 farmers previously interviewed enabled us to decipher the crucial role of mutual aid in maintaining urban farms.MethodsThe survey data collected from 88 farmers chosen at random from the 202 farmers previously interviewed enabled us to decipher the crucial role of mutual aid in maintaining urban farms.ResultsThe results show that 79.5% of the surveyed farmers resort to mutual aid to ensure the vegetable production cycle. More specifically, this mutual aid consists in sharing resources, for which the farmer would interact 15.1 times with other farmers, and in sharing agricultural know-how, for which the farmer would interact 11.6 times with other farmers. Four categories of resources are defined in this mutual aid network: highly exchanged resources with a high exchange intensity (hoes, watering cans, plant protection products and chicken droppings), highly exchanged resources with a low exchange intensity (land capital, spades, and seeds), lowly exchanged resources with a low exchange intensity (motor pumps and buckets) and non-exchanged resources (financing, labor, chemical fertilizers). Agricultural know-how such as soil preparation, soil fertility management, pest control and sales techniques are widely shared. Characteristics such as gender, age, experience, religious affiliation, and farmer status in the household are statistically significant explanatory factors of mutual aid. In addition, neighborhood relations, kinship and religious affiliation are social ties that enable farmers to help each other.DiscussionThe results provide useful information on the crucial role played by informal mutual aid networks in maintaining urban farms in the face of the negative consequences of chaotic urbanisation and climate change. The study recommends that policymakers and agricultural extension services take these networks into account when drawing up policies for disseminating innovations. For, although informal, they constitute powerful and inexpensive channels of communication in an inoperative institutional context of urban agriculture.

Occupational Hearing Hazards among Informal Sector Welders in Lubumbashi, Democratic Republic of Congo

Abstract: Introduction: Noise, an undesirable sound which is found in all areas of occupational activity, is still a matter of concern given the damage it causes. Various machines and tools, from simple to sophisticated ones, produce several types of noise in the workplace.
