The Factories Act of 2004, the Employee Compensation Act of 2010, the Minerals Oil Safety Regulation of 1999 and the Harmful Waste Act of 2004 are pieces of legislation that included provisions for the safety, health and welfare of Nigerian workers beyond the Constitution of the Federal Republic of Nigeria 1999, and the Labour Act of 2004. This paper critically examined the extent to which these laws, with more emphases on the Factories Act of 2004 which made provisions for the safety, health and welfare of Nigerian workers and how the tenet of these laws has been enforced to reduce occurrence of accidents at workplace. This paper examined Part III of the Act, dealing with the training and guidance of naive workers, in that, no person shall be employed at any machine or in any process that is likely to cause injury, unless he has been trained by a more knowledgeable person about the dangers involved. Part III further states that factories shall provide a means of escape in case of fire, and all escape routes shall not be obstructed. Part IV addresses the welfare of persons employed, which includes the supply of clean drinking water, made available in containers, renewed daily, and suitable clean washing facilities. The findings showed that, in spite of the provisions in the Factories Act as well as other extant laws stipulating how workers safety, health and welfare is to be catered for, the rate of accidents at workplaces is increasing. Meanwhile, the examined laws will still require further review to include some of the observations and suggestions made in this work. Also, the major challenges found to be associated with the effectiveness of the Factories Act in ensuring safety, health and workers was perceived to be that the institutional agencies were not doing enough to regularly engage firms by enforcing corrective and punitive measures to erring firms. Therefore, the study recommends a special task force be setup to ensure daily compliance, the Ministry should be called to order for failure of exerting corrective measures when necessary. Finally, labour unions, human right organizations and other nongovernmental agencies should sensitize workers of their rights, privileges and protection stipulated by the law.
