Eyewash and shower equipment are emergency rescue facilities used in toxic and hazardous working environments. When the eyes or body of the site operator comes into contact with toxic, harmful and corrosive chemicals, the eyewash can be used for emergency flushing or showering of the eyes and body with these devices, mainly to prevent the chemicals from causing further harm to the human body, but these The equipment is only a preliminary treatment of the eyes and body.
Eyewash was widely used in most factories, laboratories, and hospitals in foreign developed industrial countries (the United States, the United Kingdom, etc.) as early as the 1980s. Its purpose is to reduce the damage to the body caused by toxic and harmful substances at work, and it is widely used in petroleum, chemical, semiconductor industry, pharmaceutical manufacturing and places where hazardous materials are exposed.
Generally, the choice of eyewash is investigated from two aspects: (1) inspect the manufacturer of the eyewash (2) inspect the product of the eyewash.
(1) Investigate eyewash manufacturers
The first step: Make sure that the eyewash manufacturer has a plant and a large scale! The manufacturer has many parts of the self-produced eyewash. Various services!
Step 2: Make sure that the eyewash manufacturer has a production team, these teams have the awareness of safe production, and secondly know the ability to install and repair on-site!
The third step: Have distributors who provide services in various places, provide accessories, product distribution, etc.!
Step 4: Come to confirm the factory of the eyewash manufacturer!
Step 5: Confirm that there is a sample room for the eyewash in the eyewash manufacturer, as well as technical experts and professional engineers!
Step 6: Check the qualifications and honors of the eyewash manufacturers!
(2) Investigate eyewash products
First: Decide based on toxic and hazardous chemicals at the work site
When there is chloride, fluoride, sulfuric acid or oxalic acid with a concentration of more than 50% at the use site, you can only choose a stainless steel eyewasher made of ABS or a specially treated high-performance stainless steel eyewasher. Because the eyewash made of stainless steel 304 material can resist the corrosion of acids, alkalis, salts and oils in general, but it cannot resist the corrosion of chloride, fluoride, sulfuric acid or oxalic acid with a concentration of more than 50%. In the working environment where the above substances exist, the eyewash device made of stainless steel 304 material will be destroyed to a large extent in less than six months. The concept of ABS dipping and ABS spraying is different. ABS dipping uses ABS powder instead of ABS liquid dipping.
1. The characteristics of ABS powder dipping: ABS powder has strong adhesion force, the thickness reaches 250-300 microns, and the corrosion resistance is very strong.
2. The characteristics of ABS liquid dipping: ABS powder has very poor adhesion, with a thickness of 250-300 microns, and strong corrosion resistance.
Second: Decide according to the local winter temperature
Except in South China, other regions will have weather below 0°C in winter, so there will be water in the eyewash, which will freeze the eyewash and affect the normal use of the eyewash.
To solve the problem of water accumulation in the eyewash, it is necessary to use an antifreeze eyewash, an electric heat tracing eyewash, or an electric heating eyewash.
1. The anti-freezing eyewash is used to empty the water in the entire eyewash after the eyewash is used or when the eyewash is in standby state. The antifreeze eyewash has an automatic emptying type and a manual emptying type. In general, the automatic emptying type is adopted.
For East China, Central China, and Southwest China, the frozen soil layer in the winter is generally 20-30 cm. The water inlet pipe can be made of insulation materials to prevent water from freezing in the water inlet pipe. An above-ground automatic emptying antifreeze eyewash can be used. The eyewash device can automatically drain the accumulated water in the entire eyewash device to prevent freezing.
For the Northeast, North China and Northwest regions, the frozen soil layer in the winter is generally 50-190 cm. The above-ground antifreeze eyewash obviously cannot solve the problem of water ingress and antifreeze. The buried automatic emptying antifreeze eyewash must be used.
The eyewash device has the antifreeze valve placed below the frozen soil layer, and uses the switch on the ground to control the water intake and drainage of the eyewash device. The eyewash device can automatically empty the entire eyewash device and the water in the water inlet pipe below the ground to prevent freeze.
2. In areas that can prevent freezing and increase the water temperature, you should use an electric heating eyewash or an electric heating eyewash
The electric heat tracing eyewash is heated by the electric heating tape, so that the water in the eyewash will not freeze, which can increase the water temperature of the eyewash to a limited extent, but it cannot raise the water temperature of the spray at all. (Remarks: The flow rate of eyewash is 12-18 liters/minute; the spray is 120-180 liters/minute)
The electric heating eyewash is heated by an electric heating system, so that the water in the eyewash will not freeze, and the water temperature of the eyewash and spray can be increased.
Third, decide based on whether there is a water source in the workplace
For those who do not have a fixed water source in the workplace, or who need to change the workplace frequently, a portable eyewash can be used. This type of eyewash can be moved to the required position on the job site, but this type of small portable eyewash only has the function of washing the eyes, but not the spray function, and the water flow for washing the eyes is much smaller than that of the fixed eyewash. Only the large portable eyewash has the function of spray and eyewash.
For work sites with fixed water sources, fixed eye washes are used, which can be directly connected to the tap water at the site, and the water flow is large.
There are many types of fixed eyewash, which can be selected according to the factory’s own needs.
Compound eyewash: with sprinkler system and eyewash system directly installed on the ground
Vertical eyewash: there is no sprinkler system and eyewash system directly installed on the ground
Wall-mounted eyewash: there is no sprinkler system, there is an eyewash system directly installed on the wall
Desktop eyewash: There is no spray system and an eyewash system directly installed on the work surface
Sprinkler: there is a sprinkler system without an eyewash system directly installed on the ground
Sprinkler head: with sprinkler system without eyewash system, directly installed on the wall and ceiling
When the body and eyes of the site operator come into contact with toxic and hazardous substances or other corrosive chemicals, these devices can be used to flush or flush the eyes and body in an emergency, mainly to avoid further harm to the human body caused by the chemicals.
How much does the eyewash on the market generally cost? Let our market analysis investigator analyze it for you. The safety factor is relatively high. Therefore, many engineering projects, bidding, factory reconstruction, and new chemical development zones all specify the GD6610 composite type. eye washer. For investors who are investing in the production of eyewash for the first time, choosing to be a high-quality eyewash brand is not as good as cutting corners and making money, and the benefits are greater, and there is no responsibility in the later period! For this, there is a strong criticism. More born for future enterprises! Now employees are increasingly protected by the state, and companies without security awareness are given blacklists. . .
So how much is a composite eyewash like the above? In fact, the price of a GD composite eyewash is only about 980-3500 yuan. If it catches up with the event, the price may be lower. In fact, there are many types of eyewashes. -Portable-desktop-basin-wall-hanging-vertical eyewash, etc., antifreeze with electric heating-temperature control-electric heating-buried eyewash and so on. . .
