新中国成立以来，随着大规模经济建设的展开和工业体系的不断完善，我国的劳动保护事业从无到有，从小到大，日益发展壮大。特别是十一届三中全会以来劳动保护和安全生产工作得到了长足的发展，各产业部、各省、市、自治区及交通、公安系统纷纷成立了各自的劳动保护科研机构，? Since the founding of New China, with the launching of large-scale economic construction and the constant improvement of the industrial system, the cause of labor protection in our country grows up from scratch, from an early age to an increasingly large age. Especially since the Third Plenary Session of the 11th CPC Central Committee, labor protection and safety work have made great strides. Various industrial departments, provinces, municipalities and autonomous regions, and transportation and public security departments have set up their respective labor protection scientific research institutions in succession.
