Computers / Business Equipment Computer systems and electronic equipment are vulnerable to power surges and other electrical disturbances. With computers widely used in the classroom, a breakdown can be disruptive to learning, as well as expensive. Schools also use a wide variety of office equipment, including computers, data systems, printers, scanners, copy machines and fax machines. Fragile electronic circuitry can be damaged by power problems that originate from utility electrical lines or equipment within the school facility. © 2007 The Boiler Inspection & Insurance Company of Canada.     All rights reserved.
