It is essential to maintain safe working conditions to prevent accidents and injury to any person or damage to any object in a work area.
New staff and visitors must be informed of the appropriate safety procedures.
Any transgression of the procedures must be reported.
As a computer user or a technician, you should be aware of all possible dangers.
A safe workspace is clean, organized, and well lit.
Follow proper procedures for handling computer equipment.
Failure to follow the prescribed safety procedures could result in fines, criminal convictions, damage to equipment, claims for damage from the owner of the property and data or injury.
The proper disposal or recycling of hazardous computer components is a global issue.
Make sure to follow regulations that govern how to dispose of specific items.
When an organization violates these regulations, there can be legal consequences.
Follow the basic safety guidelines to prevent cuts, burns, electrical shock, and damage to eyesight.
As a best practice, make sure that a fire extinguisher and first aid kit are available in case of fire or injury.
Remove your watch or any other jewelry and secure loose clothing before starting work.
Turn off the power and unplug equipment before opening the case and performing service.
Cover any sharp edges inside the computer case with tape.
Never open a power supply or a monitor.
Do not touch areas in printers that are hot or use high voltage.
Know where the fire extinguisher is located and how to use it.
Know where the first aid kit is located.
Keep food and drinks out of your workspace.
Keep your workspace clean and free of clutter.
Lift heavy objects with your legs to avoid back injury.
Static electricity is the buildup of an electric charge resting on a surface, which can be destructive to the electronics in a computer system.
Electrostatic discharge (ESD), harsh climates, and poor-quality sources of electricity can cause damage to computer equipment.
At least 3000 volts of static electricity must be built up before you can feel the ESD, but less than 30 volts of static electricity could damage a computer component.
Static electricity can build up on a person walking across a carpeted floor.
If the environment temperature is too high, equipment can overheat.
If the humidity level is too low, the chance of ESD increases.
If the humidity level is too high, equipment can suffer from moisture damage.
A tool kit should contain all the tools necessary to complete hardware repairs.
Mercury, commonly used in the manufacturing of batteries, is extremely toxic and harmful to humans.
When disposing of batteries, monitors, and toner cartridges, comply with local environmental regulations.
When handling motherboards, cards, or drives, don’t touch the chips on the device, hold expansion cards by the edges, and don’t touch any soldered components on a card, and don’t touch the edge connectors unless it’s absolutely necessary.
Batteries from portable computer systems may contain lead, cadmium, lithium, alkaline manganese, and mercury, which do not decay and will remain in the environment for many years.
In a classroom environment, after you have reassembled everything, have your instructor check your work before you put the cover back on and power up.
The MSDS sheet contains chemical reactivity and incompatibilities information that includes spill, leak, and disposal procedures.
To determine whether a material used in computer repairs or preventive maintenance is classified as hazardous, consult the manufacturer MSDS.
Monitors and power supplies contain such very high voltages that you should not wear antistatic wrist straps when repairing them.
In this part of the chapter, you learn how to take apart a desktop computer and put it back together, a skill needed in this and other chapters as you learn to add or replace computer parts inside the case and perhaps even build a system from scratch.
The MSDS sheet also includes protective measures for the safe handling and storage of materials.
