or Faulty Tools
Computer System Servicing (Grade
10)

2. Lesson Overview
• In this lesson, you will learn:
• - How to check hand tools for proper
operation and safety.
• - How to identify and mark unsafe or faulty
tools for repair.
• - The importance of tool safety in computer
system servicing.

3. Why Safety Matters
• Faulty tools can lead to:
• - Workplace accidents and injuries.
• - Damage to equipment and tools.
• - Decreased efficiency and productivity.
• By ensuring tools are safe, we create a safer
work environment.

4. Definition of Hand Tools
• Hand tools are manually operated tools used
for various tasks in computer system servicing.
• Examples include:
• - Screwdrivers
• - Pliers
• - Wire cutters

5. Definition of Faulty Tools
• Faulty tools are tools that are damaged or not
functioning properly.
• Common defects include:
• - Cracked handles
• - Rusted surfaces
• - Loose parts

6. Importance of Tool Inspection
• Tool inspection is the process of checking tools
for defects or issues before use.
• Purpose:
• - Ensure safety of the user.
• - Maintain tool efficiency.
• - Prevent accidents and tool damage.

7. Common Defects in Tools
• Examples of common tool defects:
• - Loose or damaged handles.
• - Dull or blunt edges.
• - Corrosion or rust.
• - Misaligned parts.

8. Visual Inspection of Tools
• Steps for visual inspection:
• 1. Look for visible cracks or damage.
• 2. Check for signs of rust or corrosion.
• 3. Ensure all parts are securely attached.

9. Functional Testing of Tools
• Functional testing involves:
• - Checking if the tool operates as intended.
• - Example: Test the grip of pliers or the
sharpness of a screwdriver.
• - Identify any unusual behavior during use.

10. Identifying Unsafe Tools
• Criteria for identifying unsafe tools:
• - Structural integrity: No cracks or breaks.
• - Operational efficiency: Tool performs its
function.
• - Absence of defects: No rust, sharp edges, or
loose parts.

11. Marking Unsafe Tools
• Tools identified as unsafe should be marked
for repair or disposal.
• Use standard labels, such as:
• - 'Do Not Use'
• - 'For Repair'
• - 'Damaged Tool'
• Ensure the label is clearly visible.
