II. Introduction

Computer assembly and disassembly involve handling sensitive electronic components and electrical devices. Following Occupational Health and Safety (OH&S) procedures ensures the safety of the technician and protects computer equipment from damage.

Safety should always be the first priority before performing any computer servicing task.

III. The 5S Principles

The 5S methodology is a workplace organization system that promotes efficiency, cleanliness, and safety.

5S Principle Japanese Term Description
Sort Seiri Remove unnecessary tools and materials from the workplace.
Set in Order Seiton Arrange tools and materials properly for easy access.
Shine Seiso Keep the workplace clean and free from dust.
Standardize Seiketsu Maintain consistent workplace organization and procedures.
Sustain Shitsuke Develop discipline in maintaining cleanliness and safety.

IV. The 3Rs of Waste Management

The 3Rs help reduce waste and protect the environment during computer servicing activities.

3Rs Description
Reduce Minimize the use of unnecessary materials and resources.
Reuse Use functional components and materials again whenever possible.
Recycle Dispose of electronic waste properly through recycling programs.

V. Personal Protective Equipment (PPE) for Computer Systems Servicing

Image PPE Purpose
Anti-static Wrist Strap Anti-static Wrist Strap Prevents electrostatic discharge that can damage components.
Anti-static Mat Anti-static Mat Protects electronic parts from static electricity.
Safety Glasses Safety Glasses Protects eyes from dust and small particles.
Face Mask Face Mask Prevents inhalation of dust during cleaning.
Gloves Gloves Protects hands from cuts and sharp edges.
Rubber Sole Shoes Rubber sole shoes They protect you from electrical shocks by providing a non-conductive barrier, and guard against trips or slips on slippery lab
