17、. WORK FROM SCAFFOLDS 脚手架作业Where scaffold access has been provided, it shall only be used for which it has been designed and constructed. The scaffold shall only be used when the appropriate Scaffold Inspection Tag is attached. 使用脚手架时应遵循有关的设计和建造要求。脚手架只有经过检查并贴上标签后才能使用。Whilst erecting and dismantling
18、scaffolding fall protection must be afforded to the scaffolding erectors whilst ascending and descending partly erected or dismantled scaffolds. Safe access and egress can be achieved by various methods. When ascending and descending scaffolds an independent ladder access can be erected with landing
19、 stages that are fully boarded and hand railed with access to each lift of the scaffold which is progressively erected or dismantled with the main body of the scaffold structure .If this method is impractical safe access can be arranged onto the scaffold from the structure floors. In the event that
20、either of these means is not acceptable man baskets and crane access can be used provided there is a safe means of landing personnel on the scaffold structure. If ascending or descending the scaffold structure is required then 100 % tie off method with a double lanyard safety harness must be used.安装
21、和拆卸脚手架时，在提升或降下脚手架部件的过程中，必须对工人进行充分的保护。可以采用各种方法安全的进入或离开。当竖起和降下脚手架时，可以用栈桥建一个独立的梯子，栈桥铺满平板，有扶手，从上面可以随着脚手架主体结构的安装或拆卸进入每一层脚手架。如果这个办法不行，可以从结构楼层安全走上脚手架。如果这些办法都不行，可以使用载人吊篮和吊车，不管怎样必须采用安全的方法将人放在脚手架结构上。如果搭设或拆除脚手架结构，则必须100%系挂双系索（2个挂钩）安全保险吊带。Whilst erecting runs of independent scaffolding steel static lines (secur
22、ely attached wire rope cable) should be erected along the lift of scaffold so that Scaffolders only hook on once and do not have to undo the safety harness when traversing along the length of the scaffold.在搭建独立脚手架时，应沿着脚手架的竖立高度安装钢管（安全地系在绳索上），这样搭脚手架的人员只需勾住安全带一次，不需要在沿着脚手架移动时松开安全带。7.

FALL ARREST坠落防护ASSESSMENT
28、评估SECCO IPMT requires suitable and sufficient steps to be taken to prevent persons from falling. Requirements are given where a person is liable to fall two meters or more requires that suitable and effective measures be taken to prevent any person falling a distance likely to cause personal injury.
29、赛科 IPMT要求采取适当而充分的措施，防止人员坠落。当人员可能从2米以上高空坠落时，必须采取合适而有效的措施，防止坠落对人员造成伤害。The contractor shall adopt effective measures to prevent personnel form slipping when working at heights, due to the cold weather and the freezing of raining or accumulated snow. All accumulation of water, ice, frost and snow shall
30、be removed from any elevated work surface when it presents a hazard to employees working at heights.承包商必须采取有效措施，防止人员在进行高空作业时由于寒冷的天气、下雨后的结冰或积雪而滑倒。对雇员高空作业构成危险的所有的积水、冰、霜、雪均应及时清除。A lightning rod or other similar suitable grounding device shall be installed to ground the structure before working at heigh
31、t can be started. Personal are forbidden to work at heights when the environmental conditions present a hazard such as severe fog and strong winds above Level Six. 在高处作业开始以前，应事先设置避雷设施或其它相似的接地装置。遇有六级以上强风、浓雾等恶劣气候不得进行高处作业。Following any period of poor weather conditions such as a snowstorm, typhoon or h
32、eavy rain, the equipment associated with working at heights shall be thoroughly inspected before resuming the work.暴风雪及台风暴雨后，应对高处作业安全设施进行全面检查，发现损坏应立即修理完善。Other considerations include:其他需要考虑的事项，包括： the indication of areas where a fall could occur注明可能发生坠落的区域 guard rails护栏 fixed ladders固定梯子 roof work顶部
33、作业 fragile surfaces易碎表面 window cleaning窗户清洁 conditions of floors and traffic routes地面和交通线路情况 formal written permit to work systems进入工作区域的正式书面许可 fall-arrest systems, including safety lines, harnesses and secure anchorage points高空坠落保护系统，包括安全绳，全身保险带和安全的悬挂点 falling objects.坠落物GUARD RAILS护栏Guardrails fac
34、ilitate mobility because there is no connection between worker and rail, and they can prevent falls. Workers may still be at a risk of falling if they lean over or through the rail to gain access. Also, a stumble near the rail needs to be considered. Regulations specify rail heights, spacing, toe-bo
35、ards, etc, and on roof edges rails are known as edge protection.工人和护栏间没有连接物，设置护栏可以方便走动，防止坠落。如果工人靠在护栏上和穿过护栏，仍可能有坠落的危险。另外要考虑在护栏边缘绊倒的可能性。有关护栏高度、间距、踢脚板和屋顶/顶部边缘的规定称作“边缘保护”。SAFETY NETS安全网Safety nets facilitate mobility because they have no connection between worker and net, and are designed to catch worke
36、rs who fall from a height. The erection of safety nets is a hazardous process and must only be undertaken by competent personnel with suitable fall protection. Nets must be installed as close to the working level as possible, to minimize the distance a worker could fall through, the maximum permitte
37、d being six meters. Consideration needs to be given to the effects of one or more workers falling through such a distance, either separately or together, there must be adequate clearance below the net to accommodate its stretching on impact, and worker(s) need to be rescued after the fall. 工人和网之间没有连
38、接物，安全网的设置便于接住从高处坠落下来的工人。安装安全网时存在一定的危险，只有采取适当防护措施（防止坠落）的合格人员才能从事这项工作。安全网应尽量靠近工作平面处安装，以尽量减少工人坠落的距离，最大允许距离是6米。应考虑到一个或几个工人分别或一起从这个距离坠落的后果。在安全网下面必须有足够的空间使网能够在受力时伸展开，在坠落后需要将工人救出来。FALL-ARREST SYSTEMS坠落制动系统Fall-arrest systems are designed to provide a safe and ergonomic connection between the worker and wor
39、kplace structure. This can reduce the workers mobility and as a result a number of different types have been developed for different working situations to provide the best combination of protection and mobility. If a fall should occur, the equipment automatically arrests the worker by a braking mean
40、s, which minimizes the fall distance and limits the arresting force to a maximum of 10kN.设置坠落制动系统的目的在于，在工人和工作场所（构筑物）之间建立一种安全并且符合人机工程的连接。这种连接可以减少工人的活动范围，对于不同的工作情况，人们研究并采用不同的连接方式，将人身保护和人员活动范围及灵活性有效的结合起来。如果发生坠落，坠落制动设备就会通过制动手段自动地捕住坠落的人员，使坠落距离最小，并将下坠力限制到最大值10kN。The simplest system consists of a full-body
41、 safety harness, which a worker puts on prior to attaching to the system; a safety lanyard, which is a flexible link between the harness and the anchorage; an anchorage, which connects the lanyard to the structure; and connectors, which link the parts of the system together. Only full-body safety ha
42、rnesses can be used in fall-arrest systems. Safety lanyards must not exceed two meters in overall length and must have an integral energy absorber. Connectors such as karabiners and hooks.: Connectors. Compatibility between parts of the system is important.最简单的系统由全身安全保险带（在连接到系统之前工人把安全带系上），一条安全系索（在保险
43、带和锚固件之间柔性连接），一个锚固件（把系索连接到构筑物上）和连接器（把系统零部件连接在一起）组成。只有全身保险带可以在防坠落系统中使用。安全系索全长不应超过2米，且必须有一个完整的能量吸收器。连接器有钢环和钩子等。系统零部件之间的相容性是很重要的。Retractable lifelines (also known as fall-arrest blocks) give more mobility. Anchored above the worker they have a spring-tensioned cable, which is paid out and retracted unde
44、r the normal movement of the worker, but a braking mechanism automatically locks the cable in response to the sudden jerk of a fall, in a similar fashion to a car seat belt. 收缩式救生索（也称为坠落制动装置）具有更大的灵活性。具体的方法是在工人上方设置了一个弹性张力绳索，当工人正常移动时放出和缩回，在突然坠落的情况下，制动机构会自动地锁住绳索，类似于汽车的安全带。Retractable Type Fall Arrester
45、s.收缩式坠落制动器Vertical travel, e.g. on tower ladders, can be protected by vertical lifelines. A sliding device moves up and down a rail or rope in response to climbing movements, but locks in response to the sudden jerk of a fall. 垂直方向（例如在塔梯上）工作时，可采用垂直救生索对人员进行保护。当工作人员攀登时，滑动装置沿着轨道或绳索上下移动，当人员意外坠落时，滑动装置会锁住
46、。Anchorage Points锚固点Cover eyebolts, mobile eyebolts, tripods, roof anchors, and deadweight anchors for use with fall-arrest equipment. It is important to ensure that the anchorage point can withstand the forces applied in a fall with an adequate safety factor. It is important to ensure that, where possible, the point is positioned above the worker to minimize the falling distance, and that sufficient space exists beneath the worker so that the length of the fall does not exceed that which is available on site. 包括有眼螺栓、活动式有眼螺栓、三脚
