Assessment of Levels of Occupational Exposure to Magnetic Fields and Ultraviolet Radiation and Ergonomic Implications among Welders in Delta State, Nigeria

Welding processes can generate ultraviolet UV radiation and extremely low frequency ELF magnetic fields, potentially harmful to welders if exceeding safe limits. This study investigated occupational exposure to ultraviolet UV radiation, extremely low frequency ELF magnetic fields, and ergonomic risks among welders in eight towns across Delta State, Nigeria namely Asaba, Warri, Oleh, Burutu, Agbor, Sapele, Kwale, and Bomadi. Using a cross sectional design, data was collected from 384 randomly selected welders. Field measurements assessed average UV irradiance ranging from 0.13 W m² in Burutu to 0.21 W m² in Warri and magnetic field flux density generally below ICNIRP limits, except for 26.3 µT in Kwale . Questionnaires revealed prevalent ergonomic risks, with over 85 of participants reporting awkward postures and repetitive movements. PPE usage varied inconsistently between towns and welding specialties, with face shields and coveralls 62 and 69 usage, respectively being most common. These findings highlight the need for enhanced awareness, improved safety practices, and appropriate PPE utilization to mitigate occupational hazards and promote healthier welding practices for welders in Delta State to mitigate occupational hazards and promote well being.
