Fixed Eye Washer
Eyewash and shower equipment are emergency rescue facilities used in toxic and hazardous work environments. When the eye or body of the field operator is exposed to toxic and harmful chemicals and other corrosive chemicals, the eye washer can perform emergency flushing or showering on the eyes and body, mainly to prevent further damage to the human body caused by chemicals, but these The device is only a Fixed Eye Washer preliminary treatment of the eyes and body.
Eyewashers were widely used in most factories, laboratories and hospitals in developed industrial countries (US, UK, etc.) as early as the 1980s. Its purpose is to reduce the harm to the body from toxic and harmful substances at work, and is widely used in petroleum, chemical, semiconductor industry, pharmaceutical manufacturing and places where dangerous materials are exposed.
Generally choose eye wash to examine from two aspects
(1) Inspect the eyewash manufacturers
The first step: to confirm that the eyewash manufacturers have a factory, the scale is large! Manufacturers have multiple parts of their own eyewash. Multi-faceted service!
The second step: to confirm that the eyewash manufacturers have a production team, these teams have a sense of safety in production, and secondly know the ability to install home, home repair!
Step 3: Have dealers providing services in various places, provide accessories, product distribution, etc.!
Step 4: Confirm the factory of the eyewash manufacturer!
Step 5: Confirm that there are sample rooms for eyewash manufacturers in the eyewash manufacturer, as well as technical experts and professional engineers!
Step 6: Check the eyewash manufacturer Fixed Eye Washer qualification, honor!
(2) Inspect eyewash products
First: Determine according to toxic and hazardous chemicals at the job site
When there is chloride, fluoride, sulfuric acid or oxalic acid in the concentration of more than 50%, you can only choose ABS stainless steel eye wash or special treatment of high performance stainless steel eye wash. Because the eye washer made of stainless steel 304 material can resist the corrosion of acids, alkalis, salts and oils in general, but it can not resist the corrosion of chloride, fluoride, sulfuric acid or oxalic acid with concentration above 50%. In the working environment in which the above substances exist, the eyewash produced by the stainless steel 304 material, in less than six months, the eye wash will be largely destroyed. The concept of ABS dip and ABS spraying is different. ABS dip is made by ABS powder dip, not ABS liquid dip.
- Characteristics of ABS powder dip-coating: ABS powder has strong adhesion strength, thickness of 250-300 microns, and strong corrosion resistance.
2, the characteristics of using ABS liquid dip: ABS powder adhesion is very poor, the thickness reaches 250-300 microns, corrosion resistance is very strong.
Second: decide according to the temperature of the local winter
Except in southern China, other areas will have temperatures below 0 °C in winter, so there will be water in the eye washer, which will affect the normal use of eye washers.
To solve the problem of water in the eyewash, you must use an antifreeze eye washer, an electric eye wash or an electric heated eye wash. - The anti-freeze type eye wash device can drain the water in the entire eye wash device after the end of the eye wash device or when the eye wash device is in the standby state. The anti-freeze type eye wash device has automatic emptying type and manual emptying type. Under normal circumstances, automatic emptying type is adopted.
For East China, Central China and Southwest China, the frozen ground layer in winter is generally 20-30 cm. The inlet pipe can be insulated to prevent water from freezing in the inlet pipe. The ground-type automatic emptying antifreeze eye washer can be used. The eye wash device can automatically drain the water in the entire eye wash to prevent freezing.
For the northeast, north and northwest regions, the frozen ground layer in the winter is generally 50-190 cm. It is obviously impossible to solve the problem of water ingress and antifreeze by using the above-ground anti-freeze type eyewash. It is necessary to use the underground automatic evacuation antifreeze type eye washer.
The eye wash device places the antifreeze valve at a position below the frozen soil layer, and uses a switch on the ground Fixed Eye Washer to control the water inlet and the drainage of the eye wash device, and the eye wash device can automatically drain the water accumulated in the entire eye wash device and the water inlet pipe under the ground to prevent the water from being trapped. Icing. - In areas where both antifreeze and water temperature can be raised, electric heating eye washers or electric heating eye washers should be used.
The electric heating eye wash device is heated by the electric heating cable, so that the water in the eye wash device does not freeze, and the water temperature of the eye wash can be increased to a limited extent, but the water temperature of the spray cannot be raised at all. (Note: the flow rate of eye wash is 12-18 liters / minute; the spray is 120-180 liters / minute)
The electric heating eye wash device is heated by an electric heating system, so that the accumulated water in the eye wash device does not freeze, and the water temperature for washing and spraying can be improved.
Third, decide whether there is water in the workplace or not.
Portable eyewashers can be used for workplaces that do not have a fixed source of water or that require frequent changes to the workplace. This category of eyewash can be moved to the location required on the job site, but this type of small portable eyewash has only eyewashing functionality, and no spray function, the water flow of the eyewash is much smaller than the fixed eyewash. Only large portable eyewashers have the function of a spray and eye wash.
For the work site with fixed water source, the fixed eye washer is used, which can directly connect to the tap water on the site, and the water flow is large.
There are many types of fixed eye washers that can be selected according to the needs of the factory.
Compound eye wash: there is a sprinkler system with eye wash system installed directly on the ground
Vertical eye wash: no spray system with eye wash system installed directly on the ground
Wall-mounted eye wash: no sprinkler system with eye-washing system installed directly on the wall
Desktop eye wash: no spray system with eye wash system installed directly on the work surface
Sprinkler: There is a sprinkler system without eyewash system installed directly on the ground
Sprinkler: there is a sprinkler system without eyewash system installed directly on the wall, ceiling
When the operator’s body and eyes are exposed to toxic or hazardous substances or other corrosive chemicals, these devices can be used for emergency flushing or showering of the eyes and body, mainly to prevent further damage to the human body caused by chemicals.
How much is the eyewash on the market? Let our market analysts give you an analysis, the safety factor is relatively high, so many engineering projects, bidding, factory reconstruction, chemical new development zone are designated GD6610 composite eye washer. For investors who have stepped into the investment in eye-washing equipment for the first time, choosing to be a high-quality eye-washing machine brand is not as good as making money by cutting corners, and the income is greater, and there is no responsibility in the later stage! There is a strong criticism of this. More for the future business! Today’s employees are increasingly protected by the state, giving blacklists to companies that are not security-conscious. . .
So how much is a composite eye washer like the above? In fact, the price of a GD composite eye washer is only about 980-3500 yuan. If you catch up with the activity price, it may be lower. In fact, there are many types of eye wash, compound type. – Portable – Desktop – Basin – Wall-mounted vertical eye washers, etc., anti-freeze with electric heating – temperature control – electric heating – buried eye wash and so on. . .
Safety Shower
How to use Emergency Shower.
A safety shower is a unit designed to wash an individual’s head and body which has come into contact with hazardous chemicals. Large volumes of water are used and a user may need to take off any clothing that has been contaminated with hazardous chemicals. Safety showers cannot be used for flushing an individual’s eyes, due to the high pressure of water from the shower, which can damage a user’s eyes.
Eyewash Station
How to use Emergency Eye wash.
An eyewash station is a unit for washing off chemicals or substances that might have splashed into an individual’s eyes before he or she can seek further medical attention. The individual needs to wash their eyes for at least 15 minutes.[2]
Drench Hose
A drench hose is an equipment that can spray water to a specific spot of the chemical exposure on individual’s body. The benefit of a drench hose is that it can be applied to an individual who cannot reach a normal eyewash or shower station or in the case where the eyewash and shower station are unavailable.
Combination Unit
A combination unit is where other units such as a shower station, eyewash station, and drench hose share the same water supply plumbing. This unit is useful in a laboratory where hazardous chemicals with different properties are used.
Eyewash Bottle Fixed Eye Washer
Also known as a personal eyewash unit, it is a supplementary for eyewash stations. However, eyewash stations cannot be replaced by eyewash bottles since they do not meet safety standards. Eyewash bottles allow an individual to flush the injured area immediately, or until the individual can reach the fixed eyewash station. Early eyewashes were designed with a single rinsing stream, but recent advancements have made eyewashes capable of flushing both eyes simultaneously. A pH neutral solution for emergency eyewash[3] may also be chosen to reduce the danger from contaminants if strong acids or alkali chemicals are presented.
