Emergency eyewash stations and showers are critical safety installations used in workplaces where hazardous substances are handled. They provide immediate decontamination to individuals exposed to harmful chemicals, biological agents, or particulate matter, minimizing injury and preventing further absorption of hazardous materials. Eyewash stations are specifically designed to flush the eyes with water or a sterile solution, removing contaminants that could cause irritation, burns, or blindness. They are essential in environments where there is a risk of eye exposure to corrosive, toxic, or irritating substances. The stations typically feature nozzles that deliver a gentle flow of fluid to both eyes simultaneously, ensuring thorough rinsing. Emergency showers, on the other hand, are used to drench the entire body, quickly removing contaminants from the skin and clothing. They are crucial in situations where large areas of the body are exposed to hazardous chemicals or when clothing catches fire. The showers deliver a high volume of water to ensure rapid dilution and removal of harmful substances. Both eyewash stations and showers must be easily accessible, clearly marked, and located within a 10-second reach of potential hazards. They should be regularly maintained and tested to ensure proper functionality. The water or solution used must be tepid, as extreme temperatures can exacerbate injuries. In summary, emergency eyewash stations and showers are vital for immediate first aid in hazardous environments, reducing the severity of injuries and providing critical time for medical treatment.

An employee should use an emergency eyewash station immediately when their eyes are exposed to hazardous substances. This includes situations where chemicals, biological agents, or particulate matter come into contact with the eyes. Specific scenarios include: 1. **Chemical Splashes**: If a chemical, whether liquid, powder, or aerosol, splashes into the eyes, immediate flushing is necessary to prevent serious injury or blindness. 2. **Dust or Particulate Matter**: When dust, metal shavings, or other small particles enter the eyes, using an eyewash station can help remove these irritants and prevent scratching or further damage to the cornea. 3. **Biological Contaminants**: In environments where biological agents are present, such as laboratories or healthcare settings, exposure to infectious materials necessitates immediate eye flushing to reduce the risk of infection. 4. **Chemical Fumes or Vapors**: If exposed to irritating or corrosive fumes or vapors that cause eye irritation, using an eyewash station can help alleviate discomfort and prevent further damage. 5. **Accidental Contact with Irritants**: Any accidental contact with known eye irritants, even if not immediately painful, should be followed by using an eyewash station to ensure no delayed reaction occurs. In all these cases, the employee should proceed to the nearest eyewash station without delay, activate the unit, and flush their eyes for at least 15 minutes, keeping their eyes open and rolling them to ensure thorough rinsing. After using the eyewash station, the employee should seek medical attention to assess any potential damage and receive further treatment if necessary.

15 to 20 minutes.

1. **Assess the Situation**: Quickly determine the need for the emergency shower. Use it if you have been exposed to hazardous chemicals or materials. 2. **Activate the Shower**: Pull the handle or lever to start the flow of water. Emergency showers are designed to deliver a large volume of water quickly. 3. **Remove Contaminated Clothing**: Immediately remove any clothing, jewelry, or accessories that have been contaminated. Do this while under the shower to prevent further exposure. 4. **Rinse Thoroughly**: Stand under the shower for at least 15 minutes. Ensure that all affected areas are exposed to the water. Use your hands to help wash away contaminants. 5. **Keep Eyes Open**: If your eyes are affected, keep them open and allow water to flow over them. Use an eyewash station if available, or ensure the shower water reaches your eyes. 6. **Avoid Hot Water**: Use only tepid water. Hot water can open pores and increase absorption of chemicals. 7. **Seek Assistance**: Call for help or have someone else call emergency services while you are using the shower. 8. **Do Not Use Soap**: Unless instructed by a safety officer, avoid using soap as it may react with certain chemicals. 9. **Aftercare**: Once decontamination is complete, seek medical attention immediately. Inform medical personnel about the substance involved. 10. **Report the Incident**: Follow your organization’s protocol for reporting the incident to ensure proper documentation and investigation. 11. **Follow Up**: Participate in any required medical evaluations or follow-up procedures as advised by healthcare professionals.

Emergency eyewash stations and showers should be inspected weekly. This frequent inspection ensures that the equipment is functioning properly and is free from obstructions or contamination. The weekly checks typically involve activating the eyewash and shower to verify that they are operational, ensuring that the water flow is adequate, and confirming that the water is clear and at a safe temperature. Additionally, the area around the equipment should be checked to ensure it is accessible and that any signage is visible and legible. Beyond the weekly checks, a more thorough annual inspection is recommended. This comprehensive inspection should assess the overall condition of the equipment, including the integrity of the plumbing, the condition of the nozzles, and the effectiveness of the drainage system. Any issues identified during these inspections should be addressed promptly to maintain compliance with safety standards and regulations, such as those set by the Occupational Safety and Health Administration (OSHA) and the American National Standards Institute (ANSI). Regular maintenance and inspection of emergency eyewash stations and showers are crucial for ensuring the safety of employees in environments where hazardous materials are present. Properly functioning equipment can significantly reduce the risk of injury in the event of exposure to harmful substances.

OSHA requires emergency eyewash stations and showers to be installed in workplaces where employees are exposed to corrosive materials. The key requirements include: 1. **Accessibility**: Stations must be located within 10 seconds (approximately 55 feet) of the hazard. They should be on the same level as the hazard and have a clear path for access. 2. **Activation**: Units must be capable of being activated in one second or less and remain operational without the use of hands. 3. **Water Flow**: Eyewash stations should deliver a continuous flow of tepid water (60-100°F) for at least 15 minutes. Showers must provide a minimum of 20 gallons per minute. 4. **Maintenance**: Equipment must be regularly inspected and maintained to ensure proper operation. This includes weekly activation to verify functionality and prevent sediment buildup. 5. **Signage and Lighting**: Stations must be well-lit and clearly marked with highly visible signs. 6. **Training**: Employees must be trained on the location and proper use of the equipment. 7. **Design Standards**: Equipment should comply with ANSI/ISEA Z358.1-2014 standards, which provide detailed specifications for performance and installation. 8. **Drainage**: Proper drainage should be considered to prevent water accumulation and potential slip hazards. 9. **Privacy**: If possible, showers should be installed in a manner that provides privacy to the user. 10. **Testing and Records**: Regular testing should be documented, and records should be maintained to ensure compliance. These requirements ensure that emergency eyewash stations and showers are effective in minimizing injury from hazardous exposures.

Emergency eyewash stations and showers should be strategically located in the workplace to ensure immediate access in case of exposure to hazardous substances. They must be installed within a 10-second walking distance from the hazard, typically considered to be about 55 feet. The path to these stations should be unobstructed, allowing for quick and easy access without the need to navigate around obstacles or through doors.
