潜水作业
Underwater Work适用范围scope of application
本作业指导书适用于本公司接受的顾客委托的潜水作业。This instruction is suitable for underwater work operations by customer authorized in the company.
2 潜水方式diving mode
采用轻潜作业。Light weight diving.
3 设备和工具equipment and tools
3.1 轻潜水装具：有开放式、密闭循环式及再生循环式，目前常用开放式。
Equipment of Light weight diving: open, closed cycle and regeneration cycle, open used commonly at current.
(1) 水面供气轻潜水装具：Equipment of light weight diving supplied by the air
surface:
A、KMB—28型轻潜水装具KMB - 28 type equipment of light weight diving:
—轻潜头盔组（即头盔整体）Helmet team of light weight diving (whole helmet)
头盔主要由头盔本体、五角带、提手、面部衬托、面窗、鼓鼻器、口鼻罩、面罩披风、通讯系统等零部件组成。The helmet is mainly composed of a helmet body, pentagon belt, handle, face support, visor, drum nasal mask, mask, mask cloak, communication system and other parts.
—潜水服组轻潜的潜水服有湿式、干式或热水式几种：Light weight diving suits divide into wet, dry or hot water suit:
湿式潜水服适用于春末至初秋这段时间的浅水潜水作业。干式潜水服是可以充气，将人体与水完全隔绝，一般用于温带地区深秋至初春这段时间的常规潜水。热水式潜水服适用于深潜水和严寒区潜水。Wet diving suit is suitable for underwater work in this period of late spring or early autumn in the shallow water. Dry diving suit can be inflated, isolated the body with water, generally used for diving in late autumn or early spring. Hot diving suit is suitable for deep diving and diving in cold region.
—软管组（DSUS—700）包括脐带、供气控制台、应急气瓶（一般是单瓶）与一级减压器、供气控制台与低压气源连接的低压软管、供气控制台与高压气源连接的高压软管。
其中脐带由供气管、加强缆和通讯电缆组成，每隔0.4m 用胶带绑扎。- Hose team (DSUS - 700) including the umbilical cord, gas console, emergency bottle (usually a single bottle) is connected with a pressure reducer, connected with low-pressure hose from gas console and low-pressure gas source, connected with high-pressure hose from gas console and
high-pressure gas source. The umbilical cord is composed of gas supply pipes, strengthen the cable and communication cable, taped every 0.4m.
3.2 供气系统Gas supply system
（1）空气压缩机：供气量和气体压力较高，可供空气潜水允许的任何深度使用，选用时，必须同实际潜水工作的用气量相适应。The air compressor: gas supply and higher gas pressure for air diving allowed to use any depth, gas consumption must adapt to the actual diving in use.
（2）储气瓶：潜水员水下呼吸一般不使用直接从空气压缩机输出的压缩空气，而先将压缩空气储入耐压容器——储气瓶，再由储气瓶经过滤器供给潜水员，既能降低温度，又便于集中使用空气。Gas cylinders: generally divers underwater do not breathe directly from the output of compressed air in the air compressor, but the compressed air into the pressure container -- gas cylinders, to supply divers through the cylinders by the filter, to reduce the temperature on the use of collected air.
（3）空气过滤器：指经两级过滤器的空气净化装置。其中第一级装置为油水分离器，用以分离所供气体内含油成份；第二级装置内装活性炭或棉蕊，用以过滤所供气体中的化学杂质成份。The air filter: refers to air purifying device through the two stage filter. The first stage device, for oil-water separator, is used to separate oil from the gas composition; second stage device loaded activated carbon or cotton core, is used to filter the chemical impurities in the gas.
3.3 潜水附属器材diving accessory equipment
（1）通讯设施：一般使用电话进行水上水下信息交流沟通，电话有故障时，应立即出水。Communication facilities: generally telephone used in underwater information communication, once the telephone is at fault, divers should be out of water immediately.
（2）保暖衣：包括绒衣、毛线衣、毛线帽、毛线袜以及衬衣等，由潜水工个人保管，注意保持清洁。Warm clothes including the wool, sweaters, shirts, sweater hat and socks, are kept by the divers cleanliness.
4 实施步骤：Implementation steps:
4.1 潜水前的准备工作The preparatory work before diving
（1）制定潜水作业实施方案the implementing plan of underwater work
潜水计划的制订，首先要认真调查作业现场的水文、气象、水流、水底底质等情况，依据任务性质和潜水作业量，准备相应的人力和装备、器材，制订潜水作业实施方案。全面分析潜水作业中的各种情况，制订出行之有效的安全措施。对医务保证和其它有关部
