Material safety data sheet (MSDS) documentation for handling and disposal

• Material Safety Data Sheet (MSDS): Government regulations that dictate handling/disposal of hazardous chemicals (e.g., batteries, displays, CRTs, toner/ink, chemical solvents).

Proper battery disposal

• Proper battery disposal (MSDS): Dispose of at a local hazardous waste facility - uninterruptible power supplies are also disposed of this way.

Proper toner disposal

• Proper toner disposal (MSDS): Recycle and reuse - many manufacturers will provide a return box, and some companies will offer discounts to recycled cartridges.

Proper disposal of other devices and assets

• Proper device/asset disposal (MSDS): Refer to the MSDS - don’t throw out without clear directions.

Temperature, humidity-level awareness, and proper ventilation

• Proper humidity for devices: 50% humidity - high humidity promotes condensation, low humidity promotes ESD.

Location/equipment placement

• Proper location/equipment placement: Refers to the proper location to store electronic devices - ensure storage areas are well-ventilated, have adequate cooling systems, and are only accessible to authorized personnel.

Dust cleanup

• Dust cleanup: Maintaining a regular dust cleanup schedule is crucial to prevent overheating and to ensure optimal airflow around electronic equipment.

Compressed air/vacuums

• Compressed air/vacuums: Using compressed air is an effective method for removing dust from hard-to-reach areas, while vacuuming can efficiently clean surfaces without causing static damage.

Power surges, under-voltage events, and power losses

Uninterruptible power supply (UPS)

• Uninterruptible power supply (UPS): A backup power source that provides temporary power to a device during an electrical outage.

Surge suppressor

• Surge suppressor: A device designed to protect electronic equipment from voltage spikes by blocking or shortening the excess voltage to ground. Look for high joule ratings (>600J protection), high amp ratings, and low voltage let-through ratings.
