INTENDED LEARNING OUTCOMES
At the end of the lesson, the learners must be able to:
1. Identified the different proper safety procedures and precautions;
2. Apply the proper safety procedures and precautions when working with computer hardware.
When working with computer hardware, one must handle electrical parts and delicate electronic equipment. Adhering to appropriate safety protocols is essential for safeguarding both the apparatus and oneself. By following these safety precautions, you can help minimize the risk of damage to computer hardware and reduce the likelihood of accidents or injuries during maintenance and repair tasks. The following are some crucial safety measures to remember:
Disconnect Power - Before working on any computer, ensure that it is powered off and unplugged. Disconnect the power source to eliminate the risk of electric shock.
Use an Anti-Static Wrist Strap - Wear an anti-static wrist strap to prevent the buildup of static electricity, which can damage sensitive electronic components. Ensure the strap is properly grounded to the computer case.
Work in a Clean and Dry Environment - Avoid working in areas with excessive dust, moisture, or humidity, as these can damage components. A clean and dry workspace helps prevent electrical shorts and improves overall safety.
Remove Jewelry - Take off rings, bracelets, and other jewelry to reduce the risk of accidental contact with electrical components.
Handle Components Carefully - Hold components by their edges to avoid contact with sensitive circuits and connectors. Be gentle when inserting or removing components to prevent damage.
Use the Right Tools - Always use the appropriate tools for the job, including screwdrivers, pliers, and cable management tools. Using the wrong tools can damage components and pose safety risks.
Disconnect External Devices - Disconnect external devices, such as printers, scanners, and USB drives, before opening a computer case. This reduces the risk of accidentally pulling or damaging cables.
Keep Work Surfaces Dry - Ensure that your work surfaces are dry to prevent electrical hazards. Avoid placing drinks or other liquids near electronic equipment.
Be Mindful of ESD - Avoid working on carpets and other surfaces that generate static electricity. If possible, use an anti-static mat and work on an anti-static surface.
Follow Manufacturer Guidelines - Refer to the manufacturer's guidelines and documentation for specific safety recommendations and procedures related to the hardware you are working on.
Use Proper Lifting Techniques - When moving heavy equipment, use proper lifting techniques to avoid strain or injury. Get assistance if needed.
Label Cables and Components - Labeling cables and components during disassembly helps ensure correct reassembly and reduces the risk of errors.
Stay Informed - Stay informed about the specific safety requirements and precautions for the equipment you are working on. Manufacturers may provide safety information in user manuals and documentation.
Emergency Procedures - Familiarize yourself with emergency procedures in case of accidents, such as the location of fire extinguishers and emergency exits.
