An eyewash station is a crucial safety device used in workplaces where employees may be exposed to hazardous chemicals, dust, or debris that can cause eye irritation or injury. Proper use of an eyewash station can prevent severe eye damage and even save vision in an emergency.
One of the most important aspects of using an eyewash station correctly is flushing the eyes for the recommended duration. Many people underestimate how long they need to rinse their eyes, which can lead to incomplete removal of contaminants and increased risks of long-term injury.
This topic will discuss why flushing time is important, how long to flush the eyes, steps for proper eyewash station use, and additional safety tips.
1. Why Is Flushing Time Important?
Flushing the eyes for the correct duration is essential for removing harmful substances and preventing further irritation or damage. When chemicals, dust, or other foreign objects enter the eye, they can cause serious burns, infections, or permanent vision loss if not removed properly.
What Happens If You Don’t Flush Long Enough?
- Chemical burns may continue to damage eye tissue.
- Small ptopics may remain lodged in the eye, leading to scratches or infections.
- Toxic substances can be absorbed deeper into the eye, increasing the risk of blindness.
Taking the right amount of time to flush the eyes ensures that all contaminants are completely removed, reducing the risk of complications.
2. How Long Should You Flush Your Eyes?
The flushing duration depends on the type of contaminant that entered the eyes. Here are the general guidelines:
1. For Mild Irritants (Dust, Pollen, Debris, or Non-Toxic Substances)
- Flush for at least 5 minutes.
- If discomfort persists, continue rinsing and seek medical attention.
2. For Chemicals That Cause Minor Irritation (Soap, Cleaning Agents, or Mild Acids/Bases)
- Flush for at least 15 minutes.
- Keep your eyelids open to ensure thorough rinsing.
- Seek medical attention if irritation continues.
3. For Strong Acids and Bases (Corrosive Chemicals Like Sulfuric Acid or Ammonia)
- Flush for at least 20 minutes.
- Strong acids can cause rapid tissue damage, so extended flushing is crucial.
- Bases (alkalis) tend to penetrate deeper into the eye and require even longer rinsing.
- Seek immediate medical assistance.
4. For Extremely Hazardous Substances (Toxic Chemicals, Unknown Substances, or Biological Contaminants)
- Flush for 30 to 60 minutes.
- If the chemical is highly toxic or causes severe burns, continue flushing while being transported to a medical facility.
The longer you rinse, the better chance you have of removing all harmful substances and minimizing permanent damage.
3. Steps for Properly Using an Eyewash Station
Step 1: Reach the Eyewash Station Immediately
Time is critical. Go to the eyewash station within 10 seconds of exposure to a hazardous substance. If available, ask a coworker to assist you.
Step 2: Activate the Eyewash Station
- Push the activation handle or foot pedal.
- Water should start flowing immediately at a consistent, low-pressure stream.
Step 3: Keep Your Eyes Open and Position Correctly
- Lean forward so that both eyes are directly in the stream of water.
- Hold your eyelids open with your fingers to ensure that water reaches all parts of the eye.
- Roll your eyes in all directions to flush out any trapped contaminants.
Step 4: Flush for the Recommended Time
- Follow the recommended flushing times based on the contaminant.
- Even if you feel relief after a short rinse, continue flushing to prevent delayed injuries.
Step 5: Seek Medical Attention
- After flushing, do not rub your eyes.
- If exposure involved hazardous chemicals, strong acids, or bases, seek immediate medical care.
- Inform the medical team about the substance involved for proper treatment.
4. Common Mistakes to Avoid When Using an Eyewash Station
Many people misuse eyewash stations in emergencies due to panic or lack of training. Here are common mistakes and how to avoid them:
1. Flushing for Too Short a Time
- Mistake: Stopping after a few seconds of rinsing.
- Solution: Follow the recommended flushing time even if the eye feels better.
2. Not Holding Eyelids Open
- Mistake: Closing the eyes while rinsing, which prevents proper washing.
- Solution: Use fingers to hold eyelids open so water can reach all areas.
3. Using High-Pressure Water
- Mistake: Rinsing with a high-pressure hose or faucet.
- Solution: Only use low-pressure, steady streams from a proper eyewash station.
4. Delaying the Use of an Eyewash Station
- Mistake: Waiting too long to rinse the eyes.
- Solution: Go to an eyewash station immediately after exposure. Every second counts.
5. Workplace Safety and Eyewash Station Requirements
Eyewash Station Placement and Accessibility
- Stations should be located within 10 seconds of hazardous areas.
- They must be free from obstructions for quick access.
- The water flow must last at least 15 minutes at a steady rate.
Regular Maintenance and Testing
- Eyewash stations should be tested weekly to ensure proper function.
- Water temperature should be lukewarm (60-100°F) to prevent shock or additional damage.
- Nozzles should be covered and clean to prevent contamination.
6. Additional Tips for Eye Safety
1. Always Wear Proper Eye Protection
- Use safety goggles, face shields, or chemical-resistant glasses when working with hazardous materials.
- Ensure eyewear meets ANSI Z87.1 safety standards.
2. Know the Location of the Nearest Eyewash Station
- All employees should familiarize themselves with eyewash station locations before an emergency occurs.
3. Train Employees on Eyewash Station Use
- Workplace safety programs should include regular training on proper eyewash procedures.
- Employees should practice simulated emergency drills to ensure quick response times.
Using an eyewash station correctly can mean the difference between full recovery and permanent eye damage. The key to effective eye flushing is knowing how long to rinse, following proper steps, and ensuring immediate response after exposure.
By flushing for the recommended duration, keeping the eyes open, and seeking medical attention when necessary, individuals can prevent long-term vision problems and ensure workplace safety. Proper training, maintenance, and protective measures further reduce risks and improve emergency preparedness.
