Study Notes

Occupational Health and Safety (OHS)

OHS focuses on preserving and protecting human resources in the workplace, crucial for both safety and productivity.
Neglecting health and safety risks, especially in computer operation, can lead to serious accidents or equipment damage.
Clean, organized, and well-lit workspaces reduce risks of injury and equipment damage.
Hazardous materials must be disposed of or recycled properly; follow specific guidelines.
Ensure safe practices include:
- Having a partner during work for safety in emergencies.
- Powering off and unplugging equipment before maintenance.
- Removing liquids from the work area to prevent electric shock or damage.
- Being cautious with tools that could cause shorts.
- Grounding oneself before touching computer parts.
- Avoiding excess force to prevent damage.
- Maintaining cleanliness to avoid accidents.
- Handling components carefully, especially avoiding contact with Integrated Circuits (IC).
- Wearing Personal Protective Equipment (PPE).
- Properly aligning pins when connecting cables.
- Recognizing contingency measures for emergencies.
- Using appropriate cleaning methods like brushes and compressed air.

Types of Computer Hardware Tools

Electro-Static Discharge (ESD) Tools

ESD is generated by friction, risking damage to computer components.
Essential tools to control ESD include:
- Anti-static wrist strap: Protects equipment from static damage.
- Anti-static mat: Prevents static buildup.

Hand Tools

Hand tools enable physical tasks using either manual or electrical power.
Common tools include:
- Flat Head Screwdriver: Loosens/tightens negative slotted screws.
- Philips Head Screwdriver: Used for positive slotted screws.
- Torx Screwdriver: For screws with a star-shaped depression, common in laptops.
- Hex Driver: Tightens nuts similar to a screwdriver for screws.
- Long-nose Pliers: Grasp and manipulate small leads.
- Allen Wrench: Drives bolts/screws with hexagon sockets.
- Wire Cutter: Strips and cuts wires.
- Soldering Iron: Joins metal conductors with solder.
- Desoldering Iron: Removes unwanted components.
- Part Retriever: Retrieves small parts in tight spaces.
- Flashlight: Illuminates hard-to-see areas.

Cleaning Tools

Proper cleaning tools are vital for maintenance and protection of computer components.
Important tools include:
- Lint-free cloth: Cleans components without scratches.
- Compressed air: Blows dust off without direct contact.
- Cable ties: Organize cables neatly.
- Parts organizer: Keeps small components sorted and accessible.

Diagnostic Tools

Diagnostic tools help troubleshoot and ensure smooth computer function.
Common tools include:
- Multimeter: Tests circuit integrity and electrical quality.
- Loopback Adapter: Checks computer port functionality.
- LAN Tester: Assesses network cable wiring.

Tools and Equipment Maintenance

Regular maintenance of tools and equipment is crucial to prevent hazards and ensure safety.
Regulations require pre-use inspections; establish a preventive maintenance schedule.
Maintenance programs should be organized, hazard-controlled, and include training.
Maintenance considerations vary by equipment type:
- Construction tools may have specific requirements.
- Power tools should be functional and safe.
- Defective tools must be tagged and removed from service.

Proper Storage of Tools, Parts, and Equipment

Proper storage enhances tool longevity and usability.
Best practices include:
- Clearly labeled and well-placed tools on boards.
- Use bins for small parts.
- Designate individuals for maintenance responsibility.
Benefits of good storage:
- Improved condition and organization of tools.
- Reduced costs and increased productivity.
- Enhanced responsibility and pride among staff.

PC Disassembly and Assembly

PC Disassembly Process

Unplugging the computer marks the first step in disassembly.
Sequential removal of internal components includes:
- Outer shell/case, system fan, CPU fan, power supply, CD/DVD drives, hard drive, RAM modules, and motherboard.

PC Assembly Process

Assembly starts with workplace preparation.
Steps include:
- Preparing the motherboard, installing CPU and fan with heatsink, RAM, and then securing the motherboard in the case.
- Connecting the power supply and installing graphics/video cards, internal drives, and add-in cards to complete the setup.
