Eyewash Devices
Eyewashes are designed for two primary dangers: foreign body irritations and chemicals. Foreign bodies usually affect one eye and once the object is removed, the flushing process can be discontinued. Chemicals on the other hand usually affect both eyes simultaneously and must be thoroughly cleansed for a long time to ensure any residuals of the chemical are removed. Not all styles or types of eyewashes fit every need. The hand-held bottles of flushing solution are an excellent choice for foreign body removal, but are not suited for full treatment of an accident involving corrosive chemicals. These bottles can be used as a "stop-gap" measure until the person can be transported to a permanent eyewash or medical treatment. Although this is normally not used in permanent facilities, it is very useful for mobile operations. Just be sure to rotate stocks, as they do expire. In cold climates, remember to protect the solution from freezing! Permanent facilities should invest in an eyewash device that is connected directly to the plumbing system. This will provide the volume of water necessary for proper treatment of any splash, spill or irritation to the eyes of a staff member. In some cases you may need more than one unit. Make sure there is an eyewash near any area of the hospital where corrosive chemicals are used. There is some flexibility in the rules, but do not expect employees to go up or down stairs, through multiple doors or even around an "obstacle course" of hazards to get to the device. Remember, the person who needs an eyewash can't see, so it has to be very easy to find! It is best to have an eyewash in every room where lab procedures are performed (e.g., with reagents or formalin), where photodeveloping chemicals are mixed or used, and where hazardous cleaning chemicals or insecticides are used. Make sure to locate the eyewash in a place where contamination from the chemicals in use will be minimized. Also be conscious of overhead cabinets or shelves, as well as adjacent obstructions; make sure an injured person can get their head and body into the correct position. Lastly, make sure that eyewashes are conspicuously identified and checked for proper operation at least monthly. Also remember to include the location and operation of eyewashes in the employee training program. The information on these pages is excerpted from |
