Subject: Dusting
In response to Pete Jermann's question regarding combining dusting with bar coding projects--I'm not a big dusting fan. When there is a heavy layer of dust, the chief result of using dust cloths (even treated cloths) is to disturb and redistribute particulate matter. Any kind of materials handling, but especially intensive handling, has the same effect. For this reason, we try to precede bar coding, shifting, and other major projects with a vacuuming cycle. In the case of huge projects (e.g., bar coding Dewey-classed materials in the general stacks), we had to compromise, cleaning only in the dustiest areas. We've found a superb vacuum cleaner for book stacks--the Princess II manufactured by Health-Mor. It's features: The hose is 10 feet long (most are 7), which makes it possible for the operator to stand on a stool and vacuum topmost shelves without lifting the machine from the floor. The machine has a 25-year rating for residential use (higher than many). It's durable enough to hold up under heavy use and has an excellent motor. The canister holds 2-1/2 gallons of debris. No disposal bag is required. Debris is suctioned into the canister itself and the canister dumped when full. A paper cone protects the motor; the canister can be filled and emptied about 5 times before the cone is replaced; it lifts out easily and a replacement drops in. The machine has a good shape--doesn't tip over and has a well- positioned carrying handle. The machine can capture particles as small as 3 microns, so very little debris reenters the air after being vacuumed up. We ordered a half dozen machines this year, with extra brush attachments and without power nozzles. Eliminating the power nozzle reduces the overall cost of the machine and ensures that it will be used only for cleaning library collections (since it's the nozzle that provides floor cleaning capability). In reserving the machines for collections cleaning, we're trying to buy them a long life and keep brush attachments as clean as possible. attachments aren't misused.
