The on-site audio-visual alarm in the emergency eye wash station in the CO2 removal section of the ammonia synthesis plant is extremely important; its function is to alert other personnel working in that section to the occurrence of an accident. In the CO2 removal units of ammonia synthesis plants in large petrochemical enterprises, this characteristic is most prominent when the plant spaces are large and there are few workers in the CO2 removal area. If an accident occurs in the CO2 removal unit and someone uses an eye washer, without an alarm to alert others, the remaining staff in that area will not be aware that an accident has taken place. Therefore, it is highly necessary to install on-site alarms for eye wash stations. Detailed operating procedures for the emergency response plan in the CO2 removal workshop of the ammonia synthesis plant – Emergency response plan for eyewash stations: The operators in the CO2 removal workshop go to the eyewash station, push the handle to activate the eyewash switch, and the eyewash fluid is automatically discharged ; Use both hands to lift the eyelids and rinse the eyes with chemicals; the rinsing time should be >15 minutes, and the flow rate of the eye wash solution should be >1.5 L/MIN. Turn on the eye wash switch by operating the manual handle, and the eye wash solution will be discharged automatically ; Use both hands to lift the eyelids and rinse the eyes and face with chemicals; the rinsing time should be greater than 15 minutes, with a flow rate of eye wash solution of more than 11.4 L/MIN. Turn off the eye wash switch by pressing the control lever, and replace the dust cover on the eye wash nozzle. In severe cases, seek medical treatment at a hospital immediately. The safety emergency response plan for the CO2 removal unit in ammonia synthesis plants was initially developed with the selection of the most suitable eye washers in mind. So, how should eye washers be chosen? When selecting eyewash stations or shower equipment for CO2 removal workshops, in addition to considering the operating conditions in such workshops, it is also necessary to take into account the standards and technical requirements that the eyewash stations or shower equipment must meet, as well as the after-sales service and safety performance of the equipment. Due to the special requirements for eyewash stations and shower equipment in the CO2 removal workshop, there are corresponding regulations regarding the materials used for such equipment. Currently, in the domestic market, the eyewash nozzles and spray nozzles of some domestic eyewash devices, imported eyewash devices, and showering equipment are generally made of ABS material, while other components are made of stainless steel or copper pipes coated with ABS material. Eyewash devices and showering equipment used in CO2 removal facilities in China are typically made of stainless steel, which offers excellent corrosion resistance, does not rust, is non-toxic, and is also durable. In the cold weather of the north, it is possible to consider installing anti-freezing devices, or other features such as lighting equipment and switches.
