China is a fast-expanding nation, and the last 30 years have seen enormous social and economic transformations. The effect of these changes was severe, which has been reviewed in this article. The article explains that these changes have led to a meteoric increase in occupational disease cases. For example, the health of those who work on ships is vulnerable to various risks. Security in the workplace should be provided to all workers as a fundamental decency. Poor working conditions, particularly in developing countries, remain, notwithstanding the widespread adoption of fundamental safety procedures. The quality of occupational hygiene and safety at a given workplace significantly affects the health of its employees. Many employees now face traditional and emerging dangers on the job due to recent developments in industrialisation, technology and globalisation. For instance, the manufacturing industry exposes workers to various health hazards. This article also explains that people from many walks of life are affected by issues related to occupational health. Safety on the job is still in a very precarious position in China. The writer has further explained China's maritime and heavy engineering industries in this article, examining their function, current trends and potential future obstacles. Occupational safety plans in China, which now rely heavily on technological solutions, must expand to include business and governmentlevel stakeholders in preparing for and raising awareness of issues related to workers' health on the job in the future.
