This paper aims to illustrate the effect of the impact damage on fatigue behavior of CF/PEEK-titanium hybrid laminates. To achieve this end, a fatigue life model was proposed to predict the S–N curves of the laminates at various initial impact energy levels and stress ratios based on the energy dissipation approach. The energy dissipation behavior of the laminates during fatigue loading under different experimental conditions was analyzed through a large amount of post-impact fatigue tests, and the correlation between the initial impact damage and the total fatigue dissipation energy was determined. The full-field axial strain distribution of the titanium layer on the impacted side of the laminate was characterized in terms of initial impact energy level and maximum stress using digital image correlation, and then the post-impact fatigue failure mechanism of CF/PEEK-Ti hybrid laminates was summarized. Finally, the validity of the proposed model was verified by fatigue tests under other conditions of stress ratio and impact energy level. It is worth mentioning that the proposed model is also applicable to other types of FMLs, and can accurately predict the residual fatigue life of laminates after impact with only one set of S–N curve data.

Developing a group of good safety professionals is a key foundation for improving a country's work safety and health. In China, the widespread concern and discussion on the development of safety professionals, or more specifically Certified Safety Engineers (CSEs) started in the early 1990s. In recent years, especially after 2002, China's CSEs entered into a holistic, systematic and rapid development period because of the formal establishment and implementation of the professional qualification system for CSEs in 2002. Moreover, CSE is now becoming the most important profession in the field of work health and safety in China, and it has been officially approved by the central government. China has rich experiences on the development and cultivation of CSEs. However, these experiences were little known to the outside world due to the lack of efficient communication. Firstly, this paper briefly reviews the history and development of CSEs in China. Then, the administrative regulation and important requirements (such as capacity requirements and the knowledge framework) regarding CSEs in China are briefly introduced. This research aims at promoting the cooperation and exchange of information on the development and cultivation of safety professionals between China and other countries, to offer useful evidence and suggestions for the development of safety professionals.

China has been experiencing dynamic industrialization because of rapid economic growth. Even with steady industrial safety improvements in recent years in China, the death rate per accident is increasing, and major accidents (MAs) as well as particularly serious accidents (PSAs) are still occurring every year. Evidently, the risk of industrial accidents, especially of MAs and PSAs is still high. Moreover, China has entered a bottleneck period for the prevention and control of MAs and PSAs. In a word, MAs and PSAs have become a significant challenge for China's industrial, social, and economic development. In recent years, especially since 2016, great attention of the Chinese government has been given to the prevention and control of MAs and PSAs. China launched its nationwide safety campaigns for firmly curbing MAs and PSAs. Some potentially effective measures and strategies in a series of safety policy documents (e.g., the ‘Guidelines for Comprehensively and Resolutely Curbing MAs and PSAs’ and the ‘Thirteenth-Five-Year Plan for Work Safety’) were also proposed, to reduce MAs and PSAs. Firstly, this paper makes a statistical analysis of China's MAs and PSAs between the year of 2002 and 2016 to figure out the current status of MAs and PSAs in China. Then this article reviews some latest major events of the prevention and control of MAs and PSAs in China to introduce the recent efforts in the prevention and control of MAs and PSAs in China. Finally, according to a series of safety policy documents in China, and the scientific research literature from other countries, this study gives a brief introduction to the future prospects of the prevention and control of MAs and PSAs in China. Obviously, this study can provide useful evidence and suggestions for the future prevention and control of MAs and PSAs both within China and in other countries.

The problem of work safety greatly affects many parts of the world, especially developing countries such as China. The release of the Thirteenth Five-Year Guideline for National Economic and Social Development in March 2016 marked the beginning of China's Thirteenth Five-Year Plan (13th FYP) period (2016–2020). Work safety continues to be a national priority. Since the release, a newly important work safety policy, namely the 13th FYP for Work Safety has been announced on February 3, 2017 in accordance with the Thirteenth Five-Year Guideline for National Economic and Social Development. What is the current status, what are new challenges and future tasks of work safety during China's 13th FYP period? The two key objectives of this paper are: (1) to analyze the current status of work safety in China, and (2) to introduce the new challenges and future tasks during China's 13th FYP period briefly. Firstly, a statistical analysis of accidents and occupational diseases in recent years in China was carried out, and a brief introduction to safety management on the national level in China has been given to analyze the work safety status in the whole of China. Secondly, combining with the demand for economic and social development in China, and according to the suggestions in the 13th FYP for Work Safety and the current status of work safety in China, the new challenges and future tasks of work safety during China's 13th FYP period are also introduced. This study can promote the cooperation and exchange of knowledge on work safety between China and other countries to provide evidence-based services for work safety.

China is a major country producing and using hazardous chemicals. Unfortunately, the hazardous chemical industry is still one of the most high-risk industries in China. In recent years, especially after two devastating hazardous chemical accidents, namely “Qingdao 11.2 Crude Oil Leaking and Explosion Accident” and “Tianjin Port 8.12 Fire and Explosion Accident” which occurred in 2013 and 2015 respectively, China has attached great importance to hazardous chemical safety. The period between 2016 and 2017 is a crucial period for the future direction of hazardous chemical safety in China because China released a series of important government documents (such as ‘Thirteenth Five-Year (2016–2020) Plan for Hazardous Chemical Safety’ and ‘Comprehensive Plan for Hazardous Chemical Safety Management (December 2016–November 2019)’) to promote hazardous chemical safety in the future. What is the future development of China's hazardous chemical safety? To answer this question, this paper attempts to briefly analyze and introduce the opportunities, problems, challenges and tasks of the future of safety with hazardous chemical industrial activities in China, according to the current situation of hazardous chemical safety in China and using the latest government documents and studies. Obviously, this study can provide useful evidence and suggestions for the future of safety management in the hazardous chemical industry both within China and in other countries.
