Safety and Risk Management Services
Introduction: •All students and employees must be familiar with the location and use of eye wash and safety showers even if they do not work directly with toxic or corrosive chemicals.
Why? You may be called upon to aid a classmate or instructor who has had an exposure.
The distance from the location of the exposed individual to the safety device should not exceed 10-15 seconds walking distance. The path to the safety shower or eye wash must be unobstructed.
The path to the eye wash or safety shower cannot involve opening a door unless: ” There is always another employee present that can open the door.
• The exposed employee can exit the room without having to manually manipulate a door knob (i.e. push bar). •The location of all eye washes and safety showers must be clearly marked with a highly visible sign. The area around the safety shower and eye wash must be well lit.
• The temperature of the water delivered should be between 60° and 95°F.
Examples Of Emergency Equipment at University of Wisconsin-Stout: Eve Washes A device used to irrigate and flush both the face and the eyes.
Examples Of Emergency Equipment at University of Wisconsin-Stout: Combination units Interconnected assembly of emergency equipment (eye wash and safety shower) supplied by a single source of flushing fluid.
The wash control valve is designed to: • Ensure a flow of water once activated without requiring the user’s hand. • Go from “off’ to “on” within 1 second. • Remain in the “on” position until manually shut off. • Be resistant to corrosion that may inhibit the operation of the valve.
Using An Eye Wash Station During An Emergency: •Hold eyelids open using the thumb and index finger to help ensure that effective rinsing has occurred behind the eyelid.
• It is normal to close eyes tightly when splashed, but this will prevent water or eye solution from rinsing and washing the chemical out. Eyelids must be held open. •Practice of this procedure is encouraged to help familiarize potential users with the feel of rinsing. It will also make it easier for the user to react both promptly and properly to an emergency situation.
Eye/Face Washing Procedures: • Always wash from the outside edges of the eyes to the inside; this will help to avoid washing the chemicals back into the eyes or into an unaffected eye. • Water or eye solution should NOT be directly aimed onto the eyeball, but aimed at the base of the nose. • Velocity of the stream of water must be such that injury to the eye is avoided.
Procedure Continued: • Flush eyes and eyelids with water or eye solution for a minimum of 15 minutes. “Roll” eyes around to ensure full rinsing. •Contact lenses must be removed as soon as possible to ensure that chemicals are not trapped behind the lenses and then the eyes can be completely rinsed of any harmful chemicals. Medical attention should be sought immediately! Ideally another person in the lab should make contact with responders or dial 9-911. The sooner medical attention can be given, the chances of not sustaining permanent damage or blindness is greatly improved.
Why this Matters! • OSHA requires that suitable means for flushing and quick drenching of the eyes and body be available in any area where toxic and/or corrosive materials are in use. • In cases of an exposure, the initial first aid treatment is to flush affected area with water for a minimum of 15 minutes.
Prevention of Accidents: • Always wear required personal protective equipment (РРЕ)!!!! •Eye/Face PPE’s include: safety glasses, goggles and face-shields Know the chemicals that you are working with. Read the Material Safety Data Sheets (MSDS) and ask questions. . Know the location of the eye wash and safety shower. •Know how to operate the safety equipment, you may need to use it yourself or assist others.
Eye/Face Wash Maintenance Requirements • The nozzles must be covered to prevent contamination and covers must automatically open when the unit is activated •Eve wash units should be activated weekly to verify operation and to flush lines for 3 minutes • Self-contained units should be activated in accordance with the manufacturer’s directions
