Note: Before disposing of equipment, be sure that any storage devices have been removed or wiped clean to prevent data theft.DISPOSING OF CERTAIN DEVICESThe following devices are common candidates for disposal, and you should observe proper environmental and safety precautions when disposing of them.Device Disposal MethodsCRT monitorsCRT monitors have a high concentration of lead, which could be a safety hazard if not disposed of properly. Some electronics retailers will accept your CRTs for recycling if you drop them off. If this isn’t possible, you should contact your local sanitation department for instructions. You can also consult the Environmental Protection Agency’s (EPA’s) eCycle program. CRTs should never be thrown into the garbage.ScannersLike CRTs, some scanners contain toxic materials that, if thrown in the trash, may prove an environmental hazard. Donate the scanner to a manufacturer or retailer or contact a waste management authority.BatteriesManufacturers of alkaline batteries today have largely eliminated mercury from their products, so disposing of these batteries in the trash is safe. Keep in mind that this doesn’t necessarily apply to older batteries, which you may need to dispose of as you would a scanner or CRT. Lithium-ion batteries used in laptops are also typically free of toxic materials and are safe to throw away normally. Due to a lack of cost-effectiveness, these batteries are typically not recycled at this point in time.

Some, such as carbon black, may be carcinogenic to humans in large quantities. Many electronics retailers as well as manufacturers accept ink and toner cartridges for recycling, or even refilling. You should avoid throwing these cartridges in the trash.Hard drivesFunctioning hard drives are good candidates for donation or re-selling, but you should take care to wipe all data on the drive before giving it away. Malfunctioning or obsolete hard drives can usually be disposed of in the trash, as they do not normally contain toxic materials.DEVICE PLACEMENTThe environmental conditions in which you work can have an effect on the devices you work with. Computers operate best in environments that are protected against several different environmental hazards, as described in the following table.EnvironmentalHazards DescriptionTemperatureExtreme temperature conditions could cause computers to malfunction or break down. It is necessary to keep computers under normal temperature conditions. Airflow around a computer and its external devices helps to dissipate the heat generated, so make sure that the components have enough room around them to prevent overheating problems.
