高空作业清洁有哪些步骤。
What are the cleaning steps for working at height.
1、处于做外墙清洁清洗的时候，首先我们应该做的正是查看作业现场，接着确定作业案例。事情查看一下屋顶的情况，确定是否可安装吊篮、吊板，吊篮、吊板在屋顶移动，有没障碍；如霓虹灯、字牌并非防碍作业等。
1. When cleaning the exterior wall, the first thing we should do is to check the operation site, and then determine the operation case. Check the situation of the roof to determine whether the hanging basket and hanging board can be installed. If the hanging basket and hanging board move on the roof, is there any obstacle? For example, neon lights and signboards do not hinder the operation.
2、接着安装运载用具，做操作前的检验。准备擦拭用具、清洗药剂。
2. Then install the carrier and do the inspection before operation. Prepare cleaning tools and cleaning agents.
3、然后作业人员携带用具上吊篮、吊板，作业工具应该拴在吊篮及吊板上，以避免不小心失手落下，伤了行人。在地面设警示防护拦绳，放置警示告牌。
3. Then, the operators should carry tools on the hanging basket and hanging plate, and the working tools should be tied on the hanging basket and hanging plate, so as to avoid accidentally falling down and injuring pedestrians. Warning rope and warning board shall be set on the ground.
4、安全防范保护配套设施是最重要的了，作业的时候应该从上到下。每擦拭完一行，整理用具、加清洗剂、横向移动吊板及吊篮，接着再继续下一行作业。
4. Security and protection of supporting facilities is the most important, the operation should be from top to bottom. After wiping each line, clean the tools, add cleaning agent, move the hanging plate and basket horizontally, and then continue to the next line.
