Eyewash stations used in chemical processing plants

We **currently do not have any standards for eye washers; domestic manufacturers of eye washers produce them in accordance with the relevant technical specifications for eye washers in the United States.** However, there are 3 versions of the American standard for eye washers, ANSI Z358-1, and the technical requirements vary among them: the ANSI Z358-1 1998 version, the ANSI Z358-1 1999 version, and the ANSI Z358-1 2004 version. The latest version is ANSI Z358-1 2004. According to the American ANSI Z358-1 2004 standard for eyewash stations, the materials used in their manufacture must possess three properties: first, properties that meet hygiene requirements. II. It has the property of resisting corrosion by environmental chemicals. III. Performance requirements that include a certain service life. In accordance with the above regulations, eye wash stations can be made of stainless steel, copper, and plastic. 1. Eye wash stations and shower equipment should be installed near the source of danger; it is ideal to be able to reach them within 10 seconds by walking quickly. They should also be installed at the same level, preferably in such a way that a straight path can be taken to them, thereby avoiding the need for rescue across different floors. 2. Under special circumstances, eye wash stations and shower equipment should meet specific requirements. For example, in environments where there may be direct exposure to strong acids or strong bases, or other highly corrosive substances or toxic and harmful materials that can be easily absorbed by the skin, eye wash stations and shower facilities must be installed as close as possible to the source of danger. 3. In laboratories where there is a possibility of exposure to the aforementioned toxic and hazardous chemicals, eyewash stations and shower facilities are generally installed in the internal passageways of the laboratory. However, sometimes the work location is far from the eye wash stations and shower facilities, which may delay rescue efforts. In this case, it is recommended to install hoses for eyewash stations and shower equipment next to the laboratory sink. This type of device is quite convenient and practical. When dangerous chemicals accidentally splash into the eyes, face, and other areas, this device can be used to rinse them as quickly as possible, providing timely protection.

　　The authoritative regulation in the chemical industry regarding health protection facilities such as eyewash stations and shower units is HG20751-95 \"Regulations for the Safety and Health Design of Chemical Enterprises.\" Articles 4.1.4 and 4.6.5 of these regulations stipulate that in work environments with toxic hazards and areas where there is a risk of chemical burns, necessary health protection facilities such as eyewash stations and shower units must be installed, with a service radius of less than 15 meters.

Generally, you just buy one from the manufacturer and install it; there is a ** at the bottom and a shower at the top.

Areas where acidic, alkaline, or irritating substances might splash into the eyes, especially in laboratories, require the installation of eye wash stations

The regulations regarding the installation of eye wash stations are quite vague in the \"Regulations on Safety and Health Design for Chemical Enterprises\". When working on projects that involve existing factories, we should always try to discuss the matter with the factory’s technical staff. First, we need to have the workers identify the areas where eye wash stations are needed. Second, it’s important to take into account the issues related to freezing and usage of eye wash stations in winter (some new factories fail to consider these factors, which results in the eye wash stations becoming unusable or getting damaged in winter). In short, practical experience in installing eye wash stations is far more important than mere theoretical guidelines

An eye washer is an emergency rescue device used in environments with toxic, harmful, and dangerous conditions. When on-site workers’ eyes or skin come into contact with toxic, harmful, or otherwise corrosive chemicals, these devices can be used to provide emergency rinsing of the eyes and skin, primarily to prevent further damage from the chemicals. However, these devices only offer preliminary treatment for the eyes and skin and cannot replace medical treatment; in severe cases, further medical care must be sought as soon as possible. Eye washers are mainly classified into the following categories: Composite eye washers. Composite eye washers are emergency equipment equipped with both a spraying system and an eye washing system, and they are installed directly on the ground for use. When chemical substances splash onto workers’ clothing or bodies, the spray system of a composite eye washer can be used for rinsing, with the rinsing time being at least 15 minutes ； When harmful substances splash onto a worker’s eyes, face, neck, arms, or other areas, the eye-washing system of a composite eye washer can be used for rinsing, with the rinsing time being at least 15 minutes. 　　Vertical eye washer: A vertical eye washer has only an eye-washing system; it lacks a spraying system, and is installed on the floor of the work site for use. When harmful substances splash onto a worker’s eyes, face, neck, arms, or other areas, the eye-washing system of a vertical eye washer can be used for rinsing, with the rinsing time being at least 15 minutes. Vertical eye washers: Imported vertical eye washers, stainless steel vertical eye washers, TOP stainless steel vertical eye washers, electrically heated vertical eye washers, electrically heated with heat tracing vertical eye washers, frost-proof vertical eye washers. Wall-mounted eye washers: Wall-mounted eye washers come only with an eye washing system; they lack a spraying system and are installed on the walls of the work site for use. When harmful substances splash onto a worker’s eyes, face, neck, arms, or other areas, the eye-washing system consisting of a wall-mounted eyewasher can be used for rinsing, with the rinsing time being at least 15 minutes. Portable eye washers are suitable for areas where there is no fixed water source or where the working environment needs to change frequently. They can be divided into ordinary portable eye washers and pressure-type portable eye washers. Application industries: offshore oil fields, desert oil fields, disease prevention and control centers, port operations, and more. 　　Laboratory desktop eye washers Desktop eye washers can be installed directly on the workbench in a workplace. These eye washers are primarily used in factory laboratories, school laboratories, or hospital laboratories. The rescue radius of a desktop eye washer is 5 meters; it consists only of an eye washing system, and can be used to rinse areas such as the face, eyes, neck, and arms. 　　Laboratory desktop eye washers: stainless steel desktop eye washers, imported desktop eye washers (with eye washing basins), imported desktop eye washers (without eye washing basins), imported wall-mounted eye washers. Emergency spray nozzles. The spray nozzles and shower head products come only with a spraying system, without an eye washing system. 　　 Emergency eye wash station The emergency eye wash station is mainly suitable for industries such as large-scale petrochemical and electronics industries, as well as disease prevention and control centers.

It’s not HG20751-95 \"Regulations for the Safety and Health Design of Chemical Enterprises\", but HG20571-95!

Our company has installed eye wash stations in the gas production, low-temperature methanol washing, methanol synthesis workshops, and methanol storage areas.

Eyewash stations should be installed in locations where accidents are likely to occur and that are relatively safe.

In fact, there are relevant design standards in China, namely \"HGT20570.14-1995 Installation of Personal Protection Emergency Systems\", which contains design requirements for eye wash stations!
