The incidence of occupational injury accidents in the metallurgy and mechanical manufacturing industries remains high,posing risks not only to the safety and health of workers but also causing heavy economic burdens to enterprises and families.The occupational injury accidents in metallurgy and mechanical manufacturing industries were caused by the following six items:human factors,machine factors,building factors,raw material factors,environmental factors,and management factors.The types and body parts of occupational injury accidents varied among different industries due to the nature of the occupation and working environment.Occupational injury accidents were both sudden and preventable.Currently,comprehensive intervention measures for occupational injury accidents at China and abroad included safety education,improving work environments,optimizing building layout and facilities,and enhancing safety management capabilities.Effective and feasible intervention measures for occupational injury accidents should be based on the characteristics and causes of occupational injury accidents in each industry,and should include corresponding interventions for workers,machines,buildings,raw materials,environment,and management.
