Guidelines for Choosing the Right Eye Wash Units
Introduction
Choosing the right eye wash unit is crucial for ensuring the safety and health of your employees. In the event of an accident or contamination, having a reliable and easily accessible eye wash unit can mean the difference between a minor inconvenience and a major medical emergency. In this article, we will discuss some important factors to consider when selecting an eye wash unit for your workplace.
Types of Eye Wash Units
There are several different types of eye wash units available on the market, each with its own unique features and benefits. The most common types are:
-
Plumbed eye wash units: These units are permanently connected to a water supply, allowing for a steady and uninterrupted flow of water. Plumbed units are typically more expensive than other types, but they offer the convenience of not having to refill the unit or replace the water.
-
Portable eye wash units: These units are self-contained and can be easily moved from one location to another. They are often used in workplaces where a permanent installation is not possible or practical, such as in a construction site or a remote location. Portable eye wash units typically use saline solution or sterile water, which must be replaced after each use.
-
Eyewash stations: An eyewash station is a combination of a plumbed or portable eye wash unit and a drench hose, which can be used to rinse contaminants from the face, head, and shoulders. Eyewash stations are often used in industrial or chemical environments where there is a higher risk of contamination.
Considerations for Selecting an Eye Wash Unit
When choosing an eye wash unit for your workplace, there are several important factors to consider, including:
-
The type of environment: The type of eye wash unit you choose will depend on the specific environment in which it will be used. For example, a plumbed unit may not be suitable for a construction site, while a portable unit may not provide sufficient water flow for an industrial setting. Consider the unique needs of your workplace and choose a unit that will be effective in that environment.
-
The type of contaminants: Different eye wash units are designed to handle different types of contaminants. Some units are specifically designed for chemical splashes, while others are better suited for particulate matter. Consider the types of contaminants that are present in your workplace and choose a unit that can effectively remove them.
-
The flow rate: The flow rate of an eye wash unit is an important factor to consider, as it determines how quickly and effectively contaminants can be removed from the eyes. The American National Standards Institute (ANSI) recommends a minimum flow rate of 0.4 gallons per minute (GPM) for portable eye wash units and 0.6 GPM for plumbed units.
-
The location: The location of the eye wash unit is also important, as it should be easily accessible in the event of an emergency. The ANSI recommends that eye wash units be located within 10 seconds of travel time from the potential hazard, and that they be clearly marked and unobstructed.
Conclusion
Choosing the right eye wash unit is essential for ensuring the safety and health of your employees. Consider the type of environment, the type of contaminants, the flow rate, and the location when selecting an eye wash unit for your workplace. By following these guidelines, you can ensure that you have a reliable and easily accessible eye wash unit in case of an emergency.
Frequently Asked Questions (FAQs)
1. What are the OSHA requirements regarding an eyewash unit?
According to OSHA, installed and portable emergency eyewash units must deliver at least 0.4 gallons (1.5L) of clean water per minute. Portable eyewash units should be capable of providing continuous water flow for a minimum of 15 minutes. The water should be readily available to wash both eyes simultaneously.
2. How many gallons is a 15 minute eye wash?
For a 15-minute eye wash, a gravity-fed (self-contained) eyewash must deliver at least 0.4 gallons of water. A plumbed eye/face wash should deliver at least 3.0 gallons of water per minute at 30 pounds per square inch pressure. A gravity-fed (self-contained) eye/face wash should also deliver at least 3.0 gallons of water for 15 minutes.
3. What is the OSHA standard for eyewash station distance?
OSHA requires that eyewash safety stations be installed within 10 seconds or 55 feet from the hazard. This ensures that employees can quickly access the eyewash station in case of an emergency.
4. What is the 10 second rule for eyewash?
The 10-second rule for eyewash stations refers to the OSHA requirement that the stations should be located within 10 seconds of the employee's work area. Additionally, the water must flow for at least 15 minutes to effectively flush the eyes.
5. What is the OSHA checklist for eye wash station inspection?
The OSHA checklist for eye wash station inspection includes replacing any broken or missing parts immediately, ensuring that nozzle caps are present to prevent contamination, and checking that the nozzles, nozzle caps, and the bowl or sink are clean and sanitary. It is also important to activate all eyewashes to make sure they are operational during regular inspections.
6. What chemicals require an eyewash station?
Eyewash stations are required in locations where workers handle injurious corrosive or caustic chemicals. Any chemicals with a pH less than 2.0 or greater than 11.5 necessitate the presence of eyewash stations to provide immediate flushing in case of eye exposure.
7. How much water should be in an eye wash?
Eyewash stations should be designed to deliver fluid to both eyes simultaneously at a volume flow rate of at least 1.5 liters/minute (0.4 gallons/minute) for 15 minutes. Combination eye and face wash stations require a flow rate of 11.4 liters per minute (3.0 gallons per minute) for the same duration.
8. What PSI should my eye wash station be?
The minimum flow requirement for eyewash stations is 30 psi, while the maximum flow is 90 psi. Eyewash stations should be able to deliver at least 15 minutes of flushing fluid at a pressure within this range.
9. What is the maximum distance to an eye wash station?
According to OSHA, emergency eyewash, eye/face wash, and shower stations must be located within 10 seconds or approximately 55 feet from the hazard. These safety equipment should be easily accessible on the same level as the hazard, and the path of travel to the stations should be free of obstructions.
10. What are the ANSI requirements for eyewash clearance?
According to ANSI standards, drench showers and eye wash units must be fully operable at the same time to properly flush the skin, eyes, and face. All flushing equipment should be located in areas that are accessible within 10 seconds or roughly 55 feet.
11. What is the minimum amount of time that you should wash your eyes out if they have been splashed with a hazardous chemical?
In case of a chemical splash, it is recommended to rinse the eyes for a minimum of 15 minutes, although rinsing time can be up to 60 minutes. The water temperature should be tolerable for the required length of time.
