How an Eyewash Station Prevents Serious Injury

Many of us know the pain of accidentally rubbing an eye after touching a lemon or hot pepper, but what if it was something more harmful? What if you were accidentally splashed in the eye with a hazardous chemical or bodily fluid while at work? 

According to the Centers for Disease Control and Prevention (CDC), 2,000 workers suffer job-related eye injuries in the United States every day. Employers are required to provide personal protective equipment and establish engineering controls to prevent injuries, but even with the best prevention, accidents happen. Ensuring that immediate and appropriate first aid is available can prevent serious injuries from developing. 

The first course of action whenever someone gets a chemical or potentially infectious material in their eye is flushing – which is why it’s vital to have an unobstructed, functional and well-maintained eyewash station nearby.   

Common Types of Eye Injuries to Healthcare Workers  

Chemical Exposure: Healthcare organizations typically have a few “caustic” or “corrosive” hazardous chemicals that can severely irritate or burn the eyes and in some cases lead to scarring or blindness. A few chemicals that fall into these categories include autoclave cleaners, glutaraldehyde, Lime-A-Way®, drain cleaner and potassium hydroxide. Employers and employees need to be aware of specific hazards, precautionary statements, and first aid instructions for every chemical they use in the workplace. That information is provided on the chemicals’ safety data sheet and should be readily available for consultation if an exposure occurs.

Bloodborne Pathogen Exposure: Healthcare workers can be exposed to blood and other potentially infectious materials while providing patient care. If the exposure route is through a mucous membrane such as the eyes, nose, or mouth, that employee should immediately irrigate the area with clean water or saline. Bloodborne pathogens include but aren’t limited to Hepatitis B, C and HIV.

First Aid Measures

For chemical exposures, consult the chemical safety data sheet. Many hazardous chemicals require immediate flushing of the eyes with water for at least 15 minutes, occasionally lifting the upper and lower eyelids, removing contact lenses if present, continued rinsing, then seeking immediate medical aid and/or calling a poison center.

For bodily fluid exposure exposures, current literature recommends immediately flushing the eyes with water or a saline wash for at least five minutes. If contact lenses are in place, they should be left in place while flushing because they are a barrier to the eye. Once the eye is thoroughly flushed, the contact lenses can be removed. 

Regulations and Compliance

The rule governing the requirement for employers is found in the Code of Federal Regulations at Title 29, Section 1910.151, and is enforced by the Occupational Safety and Health Administration, or OSHA. It specifically states, “Where the eyes or body of any person may be exposed to injurious corrosive materials, suitable facilities for quick drenching or flushing of the eyes and body shall be provided within the work area for immediate emergency use.”

OSHA refers employers to The American National Standards Institute (ANSI) and the International Safety Equipment Association (ISEA) standard for minimum performance and use requirements for eyewash and shower stations under ANSI/ISEA Z358.1-2014.

A few key standards required of eyewash stations:

  • Located within 10 seconds of hazardous materials
  • Have a valve mechanism that protects the unit from contamination and opens in one second or less
  • Free from hazards (unobstructed)
  • Delivers at least 0.4 gallons of tepid water (60-100º F) per minute for 15 continuous minutes


If not properly maintained, water systems and eyewash stations can grow bacteria and other organisms like acanthamoeba, pseudomonas and legionella, presenting serious health hazards to employees. Infections arising from these organisms can affect the eyes, skin, lungs, and other tissues with symptoms ranging from redness, drainage, pain, light sensitivity, fever, chills and confusion, and, in worst cases, require hospitalization or lead to death.

Organizations should follow eyewash station manufacturer instructions regarding the frequency and duration of flushing to reduce microbial contamination. At a minimum, eyewash stations should be activated once per week to ensure that water is flushed through the plumbing and the device is working properly. This will also allow fresh water to run through the lines and hardware, decreasing the chances of contamination from stagnant water.

Implementing an eyewash station testing log can ensure compliance and documentation of maintenance efforts. Depending on the environment, organizations might tailor this form to include water clearness, water temperature, and any specific instructions from the manufacturer.
