“…The welding process joins and cuts metal using a flame or an electric arc and other heat sources to melt and cut or to melt and join two pieces of metal [ 6 ]. There are several types of arc welding, including stick or shielded metal arc welding (SMAW), the gas-shielded methods of metal inert gas (MIG), tungsten inert gas (TIG), plasma arc welding (PAW), and submerged arc welding (SAW) [ 7 , 8 ].…”

“…The most common welding method used by informal welders is the SMAW, which uses electricity as a source of heat [ 9 , 10 ]. Informal welding sites, like many other small-scale industries, are characterized by low capitalization, and minimum investment in safety precaution procedures, putting those involved and the communities around them at risk [ 6 ].…”

“…Welding is a hazardous profession with many health and safety risks to workers, including heat exposure, burns, dangerous flying objects, radiation exposure, noise pollution, fumes (for example particulate matter ‐ PM 2.5 and PM 10 ), electrocution, and poor ergo-dynamics [ 6 , 11 , 12 ]. These occupational hazards can result in temporary and/or permanent injury, short- or long-term adverse health effects, discomfort, and even death to workers [ 6 , 11 ]. Short-term effects include cuts and burns, irritation of the eyes, nose, chest, and respiratory tract, muscle aches, coughing, fatigue, and nausea.…”

“…Short-term effects include cuts and burns, irritation of the eyes, nose, chest, and respiratory tract, muscle aches, coughing, fatigue, and nausea. Long-term health effects include an increased risk of pulmonary siderosis due to exposure to iron dust, lung, larynx, and potential cancers from agents found in smoke [ 6 , 12 ]. Many of these hazards can be minimized with adherence to occupational health and safety guideline, using personal protective equipment (PPE), maintaining equipment, practicing electrical safety, and employing proper hazard control measures [ 6 , 9 – 11 , 13 ].…”

Often with minimal formal training and protections, informal welders face significant occupational health and safety (OSH) risks. This cross-sectional study of 219 adult informal welders at 70 informal welding sites in Mwanza City, Tanzania aimed to: 1) capture knowledge and awareness of occupational risks and safety precautions, training, and self-reported work-related injuries and illness and 2) observe worker use of personal protective equipment and site safety. We hypothesized that knowledge, awareness, and site inspections would improve use of PPE and that improved safety and site inspections would reduce self-reported injuries and illness. A generalized linear model (GLM) was used to model all relationships. Robust standard error estimation was used to avoid overestimation of parameters. Having a post-secondary education (aβ = 1.01, 95% CI: 0.962, 1.061; p = 0. 0679), having training in OSH (aβ = 0.927, 95% CI: 0.872, 0.984, p = 0.014), increased knowledge of occupational risks (aβ = 1.305, 95% CI: 1.143, 1.491; p<0.001), and knowledge of safety measures (aβ = 1.112, 95% CI: 0.881, 1.404; p = 0.372) increased PPE use by 1%, 7.3%, 30.5%, and 11.2% respectively. Workers who used PPE were less likely to experience fire explosions (AOR = 0.149, 95% CI: 0.029, 0.751; p = 0.02), radiation exposure (AOR = 0.097, 95% CI: 0.016, 0.579, p = 0.01) or electric shocks (AOR = 0.012; 95% CI: 0.001, 0.11, p<0.001). Having increased knowledge of safety practices also decreased the odds of fire explosions (AOR = 0.075, 95% CI: 0.018, 0.314; p<0.001). Those with higher knowledge of occupational risk (aβ = 1.57, 95% CI: 1.404, 1.756; p<0.001) and safety measures (aβ = 1.628, 95% CI: 1.34, 1.978; p<0.001) were more likely to have more positive attitudes towards safety practices. Our findings suggest that comprehensive targeted interventions including increased knowledge of occupational risks, safety practices, and occupational health law through training, along with enforcement and inspection by government officials, would benefit the environmental and occupational health for informal welders.
