单元槽的电解车间起重机-中英对照
至关重要的是，提供电解车间起重机是用来将组装好的Nestpat单元槽从组装区域吊装到固定的BICHLORTM电解槽框架内的。起重机可能还需要用于吊装电极的预包装货箱和其他装置到工作楼层。
起重机，以及任何相关的起重横梁应当这样设定，当吊装一个单元槽时，被吊装单元槽的顶部和电解槽的顶部之间的距离至少要一点六米。
6.3 监测和维护BICHLORTM电解槽的通道
在BICHLORTM电解槽周边的以下位置需要永久通道用以一系列的监测和维护活动：
1. 沿着每一个BICHLORTM分框架的两边的全长。这是用以维修活动的 – 从分框架的总管处断开和重新连接活动的橡皮软管，和由单元槽的卸载/替换所引起的分框架分断。这个通道同样需要用在对于单元槽电压的监测和电解槽的排水软管的目视检查。
2. 到电解槽的尾端张力螺钉的所在处的通道也是需要的，用来在维修时打开和关上分框架。
7. 在设计时需要考虑的安全、健康和环境（SHE）问题
有许许多多有关于安全，健康或者环境的重要问题必须在设计时加以充分的考虑。他们包括：
1. 有毒气体的排放
电解槽产生的氯气是一种有毒气体。系统必须到位以保护工厂的工人和泄漏处以及其他泄漏的氯气以外的人群。必须提供足够的洗涤系统用以去除连续不断的工厂紧急出风口处的氯气。
2. 易燃的危险 – 火灾和爆炸
电解槽中产生的氢可以和大气中的空气或者电解槽中产生的氯气相结合，产生易燃性混合物。 这很可能在设备的内部或者工厂设备周围的大气中发生。在设计时必须集中注意力于电解槽的内部和外部以及下游工厂的易燃的危险。
此外，也可能存在有一单个的Nestpak单元槽，包含了一个严重损坏的离子膜，在极化的条件下产生氢氧混合物，其中氢的浓度高于最低可燃限度的可能性。这将很快在气体的总管处被从其他单元槽来的惰性气体流和气体流所稀释，使其混合物还原成得非可燃性的。强烈的紫外线对于从电解槽引出的半透明的排水软管中的可燃混合物来说，是一种潜在的点火源。为了消除这种点火源，将所有的排水软管都屏蔽阳光的直接照射就至关重要了。在掩盖下安装电解槽就是实现它的一个很简单的方法。
3. 电气危险
在电解槽中的高电压和高电流的使用对于在电解车间中工作的工厂工人来说，是一种潜在的危险。设备的设计应该尽量减少工厂工人所承担的风险。我们需要特别关注钢结构的绝缘和工厂工人与暴露在现场的电气管理员之间的潜在的交互作用。对工作在电解槽上或者工作在其周围的工人来说，穿着合适的安全制服（绝缘靴和绝缘手套）是很重要的。
我们同样需要集中注意力于在电解车间内的吊装操作的设计，因为通过现场电气管理员与大型项目中的正在吊装的金属设备（例如，电解槽）之间的接触，可能会导致电子的短路。
6.2 Cellroom Crane for Nestpak Modules
It is essential that a cellroom crane is provided to lift the assembled Nestpak
modules from the assembly area into the fixed BICHLORTM Electrolyser frames. The crane
is possibly also needed for lifting pre-packaged crates of electrodes and fittings to
the working floor.
The crane, and any associated lifting beam, should be set up such that, when lifting a
module, the distance between the top of the lifted module and the top of the
Electrolyser is at least 1.6 metres.
6.3 Access to BICHLORTM Electrolyser for Monitoring and Maintenance
Permanent access is required to the following locations around BICHLORTM Electrolysers
for a range of monitoring and maintenance activities:
1. Along the full length of both sides of every BICHLORTM pack. This is for
maintenance activities - disconnecting and reconnecting flexible hoses from pack
headers, and pack splitting for module removal / replacement. This access is also
needed for monitoring of module voltages and visual inspection of Electrolyser offtake
hoses.
2. Access to the end of the Electrolyser where the tensioning screws are located
is required, for opening and closing the pack during maintenance.
7. Safety, Health and Environment (SHE) Issues to be Considered in Design
There are a number of important issues relating to safety, health or environment, that
must be adequately considered by in design. These include:
1. Toxic Gas Emissions
The Electrolysers produce gaseous chlorine, a toxic gas. Systems must be put in place
to protect plant personnel and offsite population from leaks and other emissions of
chlorine. Adequate scrubbing systems must be provided to remove chlorine from
continuous and emergency plant vents.
2. Flammable Hazards - Fire and Explosion
Hydrogen produced in the Electrolysers can combine with air from the atmosphere or
chlorine produced in Electrolysers, to produce flammable mixtures. Potentially this
can take place within equipment or in the atmosphere surrounding plant equipment.
Attention must be given in design to flammable hazards in and around the Electrolyser
and the downstream plant.
There also exists the possibility of a single Nestpak module, containing a badly
damaged membrane, producing a mixture of hydrogen in oxygen during polarisation
conditions, that has a hydrogen concentration above the lower flammable limit. This
will soon be diluted in gas headers, by the inerts flow and gas flow from other
modules, to render the mixture non flammable. Powerful UV light is a potential
ignition source for the flammable mixture in the translucent offtake hoses from the
Electrolyser. To eliminate this ignition source it is essential that all the offtake
hoses are shielded from direct sunlight. Installation of the Electrolysers under cover
is a simple way of achieving this.
3. Electrical Hazards
The use of high voltages and high currents in electrolysis, is a potential hazard to
plant personnel working in the cellroom. Equipment should be designed to minimise the
risks to plant personnel. Special attention should be given to insulating steelwork,
and to the potential interaction between personnel and exposed live electrical
conductors. Wearing of appropriate safety clothing (dielectric boots and gloves) is
essential for personnel working on or around Electrolysers.
Attention should also be given to the design of lifting operations in the cellroom, as
it is possible to cause electrical shorts through contacting live electrical
conductors with large items of metallic equipment (e.g. Electrolysers) that are being
lifted.
