2.2.1事故預防
　　　根據(jù)發(fā)生的需要，任何特殊的安全防范措施都要提到。但在這一點上，一些一般性的預防措施也要注意。我們要時刻牢記，如果我們處理不慎，一些強有力的工具可造成嚴重傷害，所以我們在任何時候要很關心。熟悉機器并不能將免于意外，瞬時分心或疏忽對于有經(jīng)驗的機械師也會造成災難，對于新手來說也更容易。初學者在嘗試使用任何機器之前應該尋求指示說明，畢竟他不熟悉那些機器。這樣不僅為個人安全著想，也避免給工廠或車間造成大的損失。他應該很確切知道每個機床的停止按鈕的位置，直到確保機器處于警戒位置時，或者沒人觸碰機器的任何部分時，或者切削刀具或鉆頭不工作或不做功時，或機器的旋轉部件有碎布或其他障礙物時才啟動這按鈕。我們不應該去碰觸其旋轉部位，然而它可能是出現(xiàn)慢慢旋轉或是慢慢停止。抹布不能用來清潔運動部件。
　　　在調整機床的工作零件或切削刀或齒輪系之前，必須通過先投擲其主開關使這臺機器被孤立。令人沮喪的是，停止按鈕并不是很安全的裝置。所有的機床都會有紅色的急停按鈕，它是放置在突出的引人注意的地方，這樣就方便任何人在緊急情況下可切斷電源。

2.2.1 Accident Prevention
　　　Any special safety precautions are mentioned as the need arises. but at this point, a few general precautions are noted. It must always be borne in mind that all power tools can inflict serious injury if handled carelessly and they must be treated with profound respect at all times. Familiarity with a machine does not bring immunity from accidents, a momentary distraction or inattention bringing disaster to the experienced machinist as readily as to the novice. The beginner should seek instruction before attempting to use any machine with which he is unfamiliar, not only for his personal safety but to avoid damaging costly plant. He should be quite sure of the position of the ‘stop’ button on each machine and should never start one until he is sure that the guards are in position, that no one is touching or adjusting any part of the machine, that the cutter, drill or work is free to turn and that no rags or other obstructions are anywhere near rotating parts. Revolving parts should never be touched, however, slowly they may be turning or however smooth they appear. Rags not be used to clean moving parts.
