How to choose the right eyewasher in various workplaces

1. When workers need to wear chemical protective clothing for field operations or rescue missions, they should use a compound eye washer to rinse their eyes. This is especially important because, after working in hazardous environments or entering a rescue site, the protective clothing may be contaminated with large amounts of chemicals. Direct contact with this clothing can pose serious risks to others. Therefore, it's essential that the user first wears the full chemical protection suit and then uses the compound eye washer to thoroughly clean themselves before being approached by others.

Firefighters and on-site personnel are often at risk of being burned during firefighting operations. In such cases, a compound eyewash system can also be used to help extinguish flames, providing an additional layer of safety.

2. Wall-mounted or vertical eyewash stations are suitable for locations where only eye rinsing is required. These units are designed to clean the eyes, face, and hands. Wall-mounted models are typically installed inside workshops or on the exterior walls of facilities. The eyewash nozzles are positioned between 1.00m and 1.10m high, matching the height of vertical eyewash systems. If wall installation is not feasible, vertical eyewash units are a practical alternative.

3. In laboratories, where space is limited, desktop eyewash stations are commonly used. These compact units are ideal for small workspaces and provide quick access to emergency eye washing.

4. Portable eyewash units offer flexibility, allowing users to move them to different locations as needed. However, these systems require more maintenance and are best suited for open, flat areas. Due to harsh operating conditions, maintenance costs tend to be higher compared to fixed installations.

5. Portable pressure eyewash systems are highly versatile, as they can be placed anywhere without restrictions. They are ideal for remote work sites with limited water sources and have a typical usage time of 30 minutes. Available options include stainless steel and plastic models, each designed for specific environments and needs.

6. Wall-mounted eyewash cans are useful in areas without a permanent water supply and where frequent relocations are necessary. However, like other mobile units, they come with higher maintenance requirements.

7. In northern regions, using eyewash equipment in winter presents two major challenges:

The first issue: Water freezing inside the eyewash unit. During cold winters, water can freeze within the system, which can severely impair its function. In extreme cases, ice buildup may completely block the water flow, rendering the device useless.

The second issue: Cold water temperature. In winter, the water from the eyewash is often too cold, which can cause discomfort or even harm to the user. Ideally, the water should be lukewarm, as recommended by the ANSI Z358.1-2004 standard. However, if hot water is used, it could potentially accelerate chemical reactions, so medical advice should be sought to determine the safest temperature. The water temperature should not be excessively hot to avoid further injury to the eyes or skin.
