SAFETY
Most areas of the tower must be inspected for safe working and operating conditions. A number of items should be inspected yearly and repaired immediately in order to guarantee the safety of maintenance personnel:
• Scale remover contains acid and can cause skin irritation—avoid contact with your eyes, skin, and clothing; in case of contact, flush the skin or eyes with plenty of water for at least 15 minutes, and, if the eyes are affected, get medical attention
• Keep scale remover and other chemicals out of the reach of children
• Do not drain the spent solution to the roof or to a septic tank; always drain the spent solution in an environmentally safe way, not to the storm sewer
• Safety is all-important: all chemicals, especially acids, should be treated with great respect and han- dled with care; rubber gloves, acid-proof coveralls, and safety goggles should be worn when work- ing with chemicals
Cleaning a system through the tower, although easier and faster than some of the other methods, pres- ents one unique hazard—wind drift. Wind drift, even with the tower fan off, is a definite possibility. Wind drift will carry tiny droplets of acid that can burn eyes and skin. These acid droplets will also damage auto- mobile finishes and buildings. Should cleaning solution contact any part of the person, it should be washed off immediately with soap and water.
Using forethought and reasonable precaution can prevent grief and expense.
