Analysis of National Major Work Safety Accidents in China, 2003-2012

Article excerpt


Five of the world's most fatal work safety acci - dents in the past decade (2001-2010) occurred in China (1). Work safety accidents has become the first cause of deaths of Chinese citizens below 44 yr old (2). Work safety accidents pose a great threat to people's life, especially major accidents, defined as ones that result in at least 10 deaths. The Chinese government has established a surveillance system for monitoring work safety accident since 2001 under State of SAWS (3), which is the only authority system for work safety accidents inquiry in China.

Injuries related to transportation, mining, fire, explosion had the majority of occurrence (4-6), and the most accidents occurred in construction on certain geographic regions of China (7, 8). Previous researches had focused on the characteristics of work safety accidents, while there is very few research analyzing major accidents with mass casualties. There has no clear answer yet that whether accidents with mass casualties are a simple enlargement of general accidents, or there is inherent mechanism of accident cause and special risk factors or not. The in-depth research focused on cause mechanism of work accidents with at least 10 fatalities has important theoretical value and practical meaning to improve relevance and effectiveness of accident prevention.

To examine the national profile of the extent and type of major accidents in work safety, which causes more than 10 fatalities per accident, we analyzed data from accident inquiry system on SAWS website for the period 2003 to 2012 and provide scientific basis for prevention measures and strategies to reduce major work safety accidents and deaths in China.

Materials and Methods

Source of Data

Data from the State SAWS corresponding to the period 2003-2012 were used in this analysis. SAWS is the competent agency under the State Council in charge of the comprehensive supervision and administration of work safety and coalmines of the whole country. China has made mandatory provisions focusing on the implementation of safety standards, risk forecasting, accident reporting, accident accountability and other aspects through the development of relevant laws and regulations, departmental regulations and safety standards. The SAWS is law-based administration to strengthen the comprehensive supervision and administration of work safety and coal mines of the whole country. The SAWS collects information from provinces, cities and local data sources, including details regarding fatal accidents with more than three deaths and non-fatal injuries, and associated economic losses. The information of work safety accidents and coalmine incidents are required to report from enterprise involved to the regional agency and provincial department, and then finally submitted to the SAWS. After conducting an investigation, the SAWS announces the findings and determines about penalty. In this study, the data covered most industries except the military forces and private enterprises. Additionally, we checked statistical yearbook of road traffic accidents and public literature to supplement information and details.

The analysis was conducted using the registered data with more than 10 deaths per incident. Major accidents in transportation involved victim who was the operator, passenger, or a pedestrian stuck in or on the side of the road.

Data Analysis

After extraction, details including types of the event, year, region, number of deaths and injuries, causes of accidents were transformed into SPSS v13.0 (Chicago, IL, USA). Mortality rate and incidence of major work safety accidents used national census data. We performed analysis on the frequency of accidents and deaths, the trend, geographic distribution and type of major accidents. We analyzed the geographic distribution using hierarchical cluster analysis, focused on the frequency of accidents and deaths.

Incidence of major accident shows the occurrence probability of any person, and major accident mortality shows the dying probability. …
