RTO 蓄热体清洗属于高温、受限空间、粉尘、化学品并存的高危作业，必须严格执行动火、受限空间、高空作业等安全管理规定，核心安全事项如下：

The cleaning of RTO thermal storage bodies is a high-risk operation involving high temperature, confined space, dust, and chemicals. It must strictly comply with safety management regulations such as hot work, confined space, and high-altitude operations. The core safety precautions are as follows:

一、系统停机与安全隔离

1、 System shutdown and safety isolation

提前按程序停机，自然降温至 45℃以下，严禁高温状态下进入箱体。

Stop the machine in advance according to the program, naturally cool it down to below 45 ℃, and strictly prohibit entering the box under high temperature conditions.

关闭进气、出气、新风阀门，加盲板彻底隔离，防止烟气、可燃气体窜入。

Close the intake, exhaust, and fresh air valves, add blind plates to completely isolate, and prevent smoke and combustible gases from entering.

切断风机、燃烧器、电气控制电源，并挂牌上锁。

Cut off the fan, burner, and electrical control power supply, and hang and lock them.

二、受限空间作业管控

2、 Control of confined space operations

办理受限空间作业票，落实 “先通风、再检测、后作业”。

Apply for confined space work permits and implement the principle of "ventilation first, testing later, and work later".

进入前检测氧含量（19.5%–23.5%）、可燃气体、有毒有害气体，合格后方可进入。

Before entering, check the oxygen content (19.5% -23.5%), flammable gases, and toxic and harmful gases. Only after passing the inspection can you enter.

保持持续强制通风，安排专人监护，内外保持联络，严禁单人作业。

Maintain continuous forced ventilation, assign dedicated personnel for supervision, maintain communication both inside and outside, and strictly prohibit single person operation.

三、防火防爆与防中毒

3、 Fire and explosion prevention, as well as poisoning prevention

蓄热体附着焦油、油污、有机溶剂，严禁违章动火、吸烟、使用非防爆工具。

The thermal storage body is attached with tar, oil stains, and organic solvents. It is strictly prohibited to engage in illegal hot work, smoking, or use non explosion proof tools.

清洗产生的粉尘量大，易形成粉尘爆炸环境，控制扬尘，禁止冲击、摩擦打火。

The amount of dust generated during cleaning is large, which can easily create a dust explosion environment. Control dust and prohibit impact, friction, and ignition.

避免吸入高温粉尘、分解有毒气体，作业人员必须佩戴防尘口罩或防毒面具。

To avoid inhaling high-temperature dust and decomposing toxic gases, operators must wear dust masks or gas masks.

四、清洗作业安全要求

4、 Safety requirements for cleaning operations

优先采用真空吸尘、低压空气吹扫，慎用高压水冲洗，防止大量泥浆堵塞气流通道。

Priority should be given to vacuum cleaning and low-pressure air blowing, and high-pressure water flushing should be used with caution to prevent a large amount of mud from blocking the airflow channel.

如需使用化学清洗剂，先确认酸碱相容性，避免与残留污染物发生放热、产气反应。

If chemical cleaning agents need to be used, first confirm their acid-base compatibility to avoid exothermic and gas producing reactions with residual pollutants.

作业人员佩戴耐高温手套、护目镜、防滑鞋，防止划伤、烫伤、化学品灼伤。

Operators should wear heat-resistant gloves, goggles, and non slip shoes to prevent scratches, burns, and chemical burns.

蓄热体多为陶瓷模块，轻拿轻放，防止坍塌、坠落伤人。

The heat storage body is mostly made of ceramic modules, which should be handled with care to prevent collapse, falling, and injury.

五、用电与高空安全

5、 Electricity usage and high-altitude safety

箱内照明使用24V 以下安全电压、防爆灯具，电线绝缘完好，杜绝漏电。

Safe voltage below 24V and explosion-proof lamps are used for lighting inside the box, and the insulation of the wires is intact to prevent leakage.

高处作业系好安全带，搭设稳固脚手架或平台，严禁踩踏蓄热体。

Wear safety belts when working at heights, set up stable scaffolding or platforms, and strictly prohibit stepping on thermal storage bodies.

临时用电规范接线，做好防水、防磨损措施。

Temporary electrical wiring should be standardized, and waterproof and wear-resistant measures should be taken.

六、现场应急与收尾

6、 On site emergency response and closure

现场配备灭火器、消防水、洗眼器、急救用品，制定应急处置方案。

Equip the site with fire extinguishers, firefighting water, eye wash stations, first aid supplies, and develop emergency response plans.

及时清运清洗废料，不在炉体内堆积，防止自燃或二次污染。

Timely remove and clean waste materials, do not accumulate in the furnace body, and prevent spontaneous combustion or secondary pollution.

清洗完成后清点人员工具，恢复盲板、阀门、电气系统，试运行正常后方可交付使用。

After cleaning, count the personnel and tools, restore the blind plates, valves, and electrical systems, and only deliver them for use after trial operation is normal.
