　　Since 2009， China National Oil and Gas Exploration & Development Company Ltd. （ \"the Company\" ） has made a continual effort in sharing safety experience at all organizational levels within the Company by publicizing \"HSE Alert\" and \"HSE Bulletin\" on a weekly basis， and incorporating \"Log， Investigate and Learn from Incidents\" into the Company's
　　\"HSE Control Framework\" that makes it a mandatory requirement that all accidents/incidents be widely collected， thoroughly analyzed with lessons well learned， and precautlonary and remediaJ measures put in place so as to prevent similar incidents from recurring. Lesson sharing can and will help us identify management loopholes， avoid repeated mistakes， make equipment， installation & process safer， promote employee' s HSE awareness， and ultimately put the Company in a better position to control risks.
　　Following the initial publishing of \"HSE Warning\" in July 2010 and the second in March 2011， a third volume is now squared away. This volume is a compilation of incident management cases of the Company over the past 7 years （2011-2017）， which is indexed by Accident Type （Caught between/in/under， Confined space， Cut/puncture/scrape， Explosion/burn， Electric shock/electrocution， Noise/pressure/chemical/biological/vibration， Fall from height， Overexertion/strain， Pressure release， Slip/trip， Struck by， Drowning， Road traffic accident， Dangerous occurrence， Near miss， Environmental pollution， and other） and Life-saving Rules （Override of safeguarding sbrstems， Confined space， Driving， Energy isolation， Hot work， Line of fire， Safety mechanical lifting， Permit to work， Working at height， inadequate information， and unclassified）.
　　Albeit the terse， simplified delineation， the accidents/incidents presented in this volume are all typical， and of significant leaning values. This volume can be used as a reference for HSE professionals in the causal analysis of incidents， or as an educating material for all employees.
