Answer to Question 1
Only use power tools that are properly grounded. Stand on dry nonconductive surfaces when using electrical tools. Use only properly sized electrical cords in good condition with a GFI or GFCI. Turn on the power only after checking to see that there is no obstruction to proper operation. Disconnect the power from an electrical tool
Answer to Question 2
Desiccant wheel dehumidifiers use desiccants imbedded in a rotating wheel made out of a corrugated plastic material. As the wheel turns, the desiccant passes first through the incoming air where the desiccant adsorbs moisture from the air. Next, the desiccant passes through a regenerating zone where the desiccant is dried by the hot regenerating air.
