【正文】 受 xxxxx 委托，于 xx 年 12 月對(duì)該公司 xxx擬建工程進(jìn)行了安全預(yù)評(píng)價(jià)。安全預(yù)評(píng)價(jià)是在建設(shè)項(xiàng)目可行性研究階段，工業(yè)園區(qū)規(guī)劃階段或生產(chǎn)經(jīng)營(yíng)活動(dòng)組織實(shí)施之前，根據(jù)相關(guān)的基礎(chǔ)資料，辨識(shí)與分析建設(shè)項(xiàng)目、工業(yè)園區(qū)、生產(chǎn)經(jīng)營(yíng)活動(dòng)潛在的危險(xiǎn)、有害因素，確定其與安全生產(chǎn)法律法規(guī)、規(guī)章、標(biāo)準(zhǔn)、規(guī)范的符合性，預(yù)測(cè)發(fā)生事故的可能性及其嚴(yán)重程度，提出科學(xué)、合理、可行的安全對(duì)策措施建議，做出安全預(yù)評(píng)價(jià)結(jié)論的活動(dòng)。安全預(yù)評(píng)價(jià)有以下幾個(gè)特點(diǎn)：預(yù)測(cè)性。安全預(yù)評(píng)價(jià)在項(xiàng)目的可行性研究階段進(jìn)行，對(duì)項(xiàng)目的危險(xiǎn)、危害提出預(yù)防的對(duì)策措施，作為設(shè)計(jì)依據(jù)，可以預(yù)防危險(xiǎn)、危害的發(fā)生；艱難性。安全預(yù)評(píng)價(jià)依據(jù)的是建設(shè)項(xiàng)目可行性研究報(bào)告的內(nèi)容，所需的基礎(chǔ)資料、數(shù)據(jù)很不充分，故評(píng)價(jià)無(wú)論在深度和廣度上，有一定的局限性。在實(shí)施本項(xiàng)目的安全預(yù)評(píng)價(jià)以及預(yù)評(píng)價(jià)報(bào)告的編寫(xiě)過(guò)程中，xx市安全生產(chǎn)監(jiān)督管理局、xx 縣安全生產(chǎn)監(jiān)督管理局給予我們?cè)S多指導(dǎo)和支持，xxxxx 的有關(guān)人員也給予了大力幫助，在此一并表示感謝！目 錄第一章 概 述
