A good knowledge of statistical features of certain accidents, therefore, is the basic requirement to implement APS. In other words, major hazard identification must be performed. Statistical study on accident cases would be a powerful tool to meet this requirement. For this purpose, we collected all the related coal gas explosion accidents that analyzed in China s Coal Mine Accident and Expert Comments Set from the years of 1950-2000 (Jiefan Wang Wenjun Li 2001). The research focused on statistical features such as space, time and gas accumulation reasons, gas grade, ignition sources, accidents categories, and accident economic loss. Through this research, certain model and representativeness results will be drawn. 

Statistical characteristics of coal gas explosions at the provincial level are provided in Section 2.1, but those are not enough to constitute space-oriented major hazard identification. More detailed information is also needed, because different working faces have different conditions that may cause coal... 

The related theory about extenics is founded by the Chinese scholars Cai wen to solve the problem of subjective and objective contradictions in 1983 (Cai, 1983), it bases on the matter-element theory and extension set theory and does research on the influence degree of the described problems about quantity and quality , so as to completely know the system features (Guo et al., 2009). Due to the complexity production conditions of underground working face, there are a variety of factors that affect gas emission, how to quickly and accurately judge the reasons that why the gas emission is abnormal is an important task of gas early-warning, the extension theory can calculate the abnormal gas emission level by using the normalized correlation function. Under the condition of correct identification of gas hazard in coal mine. 

Step I There are various hazard identification techniques, discussed earlier in the chapter, that can be applied to identify the initiating event. Suppose there is a gas leakage resulting in a fire. In this case, gas leakage is the main initiating event. 

Consider how a safety case regime would have prevented this accident. The standard hazard identification procedure in the industry is a HAZOP (hazard and operability study). Two other gas plants at the Longford site had been HAZOPed but a planned HAZOP of the plant where the...

ABSTRACT Dynamic Positioning (DP) is becoming more and more popular as the reliability of DP systems is improving and as the oil and gas industry moves into deeper and harsher environments where other station keeping methods are inefficient and very costly. The most significant risk relevant to DP operations is loss of the position control ability. The environmental condition (e.g. wind, wave, and current) is one of the main influence factors on position keeping ability of the DP system which is more important in harsh environment such as Arctic and South China Sea. In this paper the operation of a DP vessel in harsh operational conditions will be discussed. Furthermore hazard identification, consequences of loss of position and identification of robust barriers to avoid disastrous outcomes in such harsh operational conditions will also be discussed with emphasis on safe disconnection from the ongoing activity.

Major advances have taken place in the last decade in the development of commercially available testing equipment which has greatly improved the quality and reduced the cost of exptl hazard assessment Quantitative data now permit routine kinetic and mechanistic studies of expl and propint reactions. Parenthetically should be mentioned the significant changes which have taken place in gas and liq chromatography which allow the separation of unstable expl process intermediates and reaction products. The identification of such reactive fractions is made possible by on-line mass spectrometers...

Identification of facilities at which an extremely hazardous substance is present in an amount in e. ccss of the threshold plaiuiing quantity, whether it is being produced, used, or stored. Transportation routes of any extremely haztirdous substance to or from the facility must be given, as well. Also to be identified were other facilities contributing or subjected to additioiuil liazards because of tlieir proximity to facilities such as hospitals or natural gas facilities...
