Eye washers are safety devices designed to flush foreign objects and chemicals from the eyes. They are commonly used in places such as factories and laboratories to protect employees and experimenters from eye injuries. The Occupational Safety and Health Administration (OSHA) in the United States explicitly mandates providing workers with a "safe and healthy working environment."

OSHA has also specifically established safety standards and regulations to improve the working environment for employees, such as in 29 CFR 1910.151, where it is stipulated that appropriate equipment should be placed in work areas where the eyes or body may be exposed to harmful or corrosive materials for emergency eye and body flushing.

National Standards for Eye Washers

The national standards GB/T 38144.1-2019 "Eye and Face Protection - Emergency Shower and Eye Wash Equipment Part 1: Technical Requirements" and GB/T 38144.2-2019 "Eye and Face Protection - Emergency Shower and Eye Wash Equipment Part 2: User Guide" have been issued. The eye/face wash products developed and produced by Sysbel have passed CMA testing and certification, fully complying with the Chinese national standard GB/T 38144.2-2019, the U.S. national standard ANSI Z358.1-2014, and the Australian standard AS4775-2007.

Principle of Eyewashers

Sysbel's latest developed eyewash features a showerhead and showerhead cover. The water flows evenly into the showerhead cover in a vortex pattern, spreading along the inner wall in an arc, and jetting out a conical water column, effectively and harmlessly rinsing the body in case of emergencies. This product category fully complies with the U.S. standard ANSI Z358.1-2014 and the Australian standard AS 4775-2007, and it has passed CSA testing and EU CE certification.

Usage Instructions for Eye Washers

Remove the dust cover, stand in a proper position, and seek assistance from colleagues if necessary.

Use your fingers to open the eyelids, gently push the valve open, bring both eyes close to the eyewasher nozzle, and rinse with a large amount of clean water for about 15 minutes.

After rinsing, close the valve, cover the dust cover, and promptly seek medical attention for further examination and treatment.

How to Use Eye Washers for Body Injuries?

Remove contaminated clothing, pull down the valve lever by hand, and water will automatically spray from the eyewash head.
Stand under the compound eyewash head and rinse the entire body with plenty of clean water.
After use, the lever must be pushed up to reset it for the next use.
Installation Precautions for Eye Washers

Must be installed near hazardous work areas, with an effective rescue radius of 10m or 15m.

Install at the same elevation if possible, preferably in a straight line to avoid obstacles.

Within the 15m radius of the eyewasher, there should be no electrical switches to prevent electrical short circuits.

Must be connected to drinking water, and the use of recycled water or process water is strictly prohibited.

The inlet diameter should be no less than 25mm to ensure an adequate water flow.

For emergency use only, strictly prohibited for regular use.

No hanging or stacking of items near the device location.

The water supply valve must be kept open and should not be closed.

There should be conspicuous signs around the eyewasher installation.

Classification of Eye Washers

Compound Eyewasher: Equipped with both a shower and eye wash system, installed on the ground for comprehensive body, eye, and face flushing.

Vertical Eyewasher: Only equipped with an eye wash system, directly fixed to the ground without wall support.

Wall-Mounted Eyewasher: Suitable for installation on walls or directly fixed to appropriate-sized pipes, with external drainage fittings to guide and discharge flushing liquid, keeping the floor clean.

Portable Eyewasher: Includes regular portable eyewashers and pressure-type portable eyewashers, suitable for outdoor or workplaces without drainage facilities, can be installed on walls as needed, providing timely and professional protection.

Handheld Rinsing Device: Used on laboratory countertops as a supplementary device to ANSI Z358.1-2014, providing rinsing for eyes, face, and body, but not a substitute for other emergency flushing equipment such as emergency eyewash and emergency shower.

Electrically Heated Emergency Shower: An indoor and outdoor freeze-resistant eyewash and flushing device for emergency assistance and primary treatment, usable in environments as low as -50°C.
