The International Labour Organization (ILO) has developed numerous conventions, protocols, and recommendations on minimum labour standards, with the majority relating to occupational safety and health systems (OSH). However, environmental issues like deforestation, desertification, flooding, erosion, oil spills, and air and water pollution, particularly in Nigeria, pose a threat to the health and safety of the many organizations in developing nations. Using a hybrid of research designs such as survey and content analysis and based on the Risk Society Theory and Sense-making Theory, this paper reviews, environmental health and occupational safety at workplaces in Nigeria. This study aims to identify environmental health and occupational safety issues in Nigeria's manufacturing sector, specifically in the iron and steel and aluminium industry, by examining inaccurate data on male and female workers. Using in-depth interviews with a total of 17 participants, the primary data was gathered from managers and senior staff members of chosen firms in Ajaokuta, Kogi State, and Lagos State, Nigeria. These were Ajaokuta Steel Company Limited (ASCL) and Alumaco Aluminium Manufacturing Co. of Nigeria Ltd., Ikeja, Nigeria. It discovers a high level of occupational health awareness, insufficient funding for safety intelligence initiatives, and a high frequency of workplace dangers. The study also finds that Nigeria was among the signatories in Africa who failed to comply with this directive. It recommends promoting occupational health services, training doctors to recognize work-related diseases, and complying with the ILO's Convention 155. The article also suggests updating laws, conducting education campaigns, investing in training, and holding employers accountable for non-compliance
