UNIT ELEVEN MACHINERY EQUIPMENT SAFETY 句子分析 Many accidents in the workplace arise out of the use of machinery and tools ranging from hand tools through machine tools such as lathes and presses to large items of mobile mechanical plant e.g. cranes or fork lift trucks. “Work equipment” is almost any equipment used by a worker at work including: machines such as circular saws, drilling machines, photocopiers, mowing machines, tractors, dumper trucks and power presses; hand tools such as screwdrivers, knives, hand saws and meat cleavers; lifting equipment such as lift trucks, elevating work platforms, vehicle hoists, lifting slings and bath lifts; other equipment such as ladders and water pressure cleaners. This will ensure that the machine cannot start before the guard is closed and will stop if the guard is opened while the machine is operating; in some cases, e.g. on guillotines, devices such as photoelectric systems or automatic guards may be used instead of fixed or interlocked guards; check that guards are convenient to use and not easy to defeat, otherwise they may need modifying; make sure the guards allow the machine to be cleaned and maintained safely; where guards cannot give full protection, use jigs, holders, push sticks etc to move the workpiece. The main mechanical safety consideration for milling machines is the swarf that is generated at the point of operation. Another safety concern is the tool cutter, which could catch operator’s clothing, jewelry, hair, or any other part of the body. 安全术语 工作设备 飞屑 作业平台 自动保护装置　 互锁保护装置 日常维护 翻译技巧（十） 定语从句及同位语从句的译法（II） 译成表示原因的分句 译成表结果的分句 译成表示条件的分句 译成表时间的分句 由as引导的特种定语从句 定语从句与先行词之间被定语短语或状语分隔 定语从句与先行词之间被谓语分隔 分译法 * * 一、带有状语意义的定语从句 Aluminum copper alloy which when heat-treated has good strength at high temperature is used for making pistons and cylinder heads for automobiles.
