The application of failure mode and effects analysis (FMEA) in safety management of the extraction plant's equipment and facilities is described in detail， including to identify the type of fault that may be caused by a single system or component in some devices， to evaluate and analysis of the possible risk of failure， in order to eliminate the risks or to reduced them to an acceptable level based on the existing technology. FMEA method can gradually reduce or eliminate the hidden trouble of equipment and facilities from the source by less cost.
